1
Q

A patient comes to see you complaining of pain in their posterior forearm when lifting a glass to drink or opening a door. What test would you do to confirm the likely diagnosis?

A

The extended finger resistance test. Production of pain towards the elbow when you press on an extended middle finger is indicative of lateral epicondylitis…or tennis elbow.

2
Q

A volleyball player went to block a shot and jammed her finger. You examine her and she cannot extend the distal joint of her finger. What does she have?

A

Mallet finger. This is when you rupture the DIP extensor tendon.

3
Q

A skateboarder slips off his board and lands on his elbow. What muscle and bone were likely involved in him “breaking” his elbow?

A

A flexed triceps with the tendon pulling on the olecranon.

4
Q

What symptoms might be manifested in someone with a synovial ganglion cyst in the dorsum of their hand?

A

That similar to carpal tunnel syndrome because cysts often form near the carpal tunnel and can compress the median nerve.

5
Q

A construction worker was cut with a circular saw below his elbow. What nerves contribute to him making the sign of benediction when asked to make a fist? What other clinical sign might he have?

A

The median nerve was severed which supplies the PIP of digits 1-3 and the DIP/MCPs of 2 & 3. Flexion of 4 & 5 remain unaffected because these are innervated by the ulnar nerve which was apparently not injured in the accident. You would also expect to see an abnormal “pinch” sign when asked to make an “OK” sign with the index and thumb because the anterior interosseous nerve is a branch off of the median nerve and innervates the flexor digitorum profundus and flexor pollicus longus.

6
Q

A football player comes to see you after a biceps curl competition with decreased sensation on the volar side of fingers 1-3. You rule out carpal tunnel syndrome first. What do you do next to figure out what’s going on?

A

Test pronation strength and see if you can reproduce symptoms when resistance is applied upon pronation (flexion of the pronator teres). Median nerve compression by the pronator teres near the elbow is likely causing his symptoms.

7
Q

What are the four common places to injure your ulnar nerve?

A

1.) Posterior to the medial epicondyle 2.) In the cubital tunnel (formed by the tendinous arch connecting the humeral and ulnar heads to the flexor carpi ulnaris 3.) Wrist 4.) Hand

8
Q

You are a concert pianist and suffer an injury to the distal portion of your forearm. What nerve do you pray is not injured and why?

A

Ulnar nerve. Injury results in atrophy of interosseous muscles and “claw hand” due to unopposed action of extensors and FDP. Adduction of the wrist is impaired. The wrist is drawn medially when attempted to flex because the FCU no longer counterbalances the FCR. MCP joints become hyperextended because flexor tone is lost and you can no longer flex fingers 4 & 5. Finally the interphalangeal joints cannot extend.

9
Q

An IV drug abuser comes to your clinic complaining of pain and weakness in his hand. You think he might have injured a nerve as he cannot extend his thumb or the MCP joints of the other fingers. What nerve may have been injured as a result of IV drug abuse?

A

He probably hit the deep radial nerve that supplies the MCP joints via the extensor digitorum.

10
Q

You do a clinical test and diagnose a patient with DeQuervian Tenosynovitis. What tendons are inflammed in this patient?

A

The abductor pollicus longus and extensor pollicus brevis

11
Q

Why in carpal tunnel do patients normally continue to have palmar sensation?

A

The palmar cutaneous branch of the median nerve does not pass through the carpal tunnel.

12
Q

Why do people progressively lose strength in their thumb in carpal tunnel syndrome?

A

The median nerve supplies the abductor pollicus brevis and opponens pollicis.

13
Q

What is the flexor retinaculum released on the medial side of the wrist in carpal tunnel release procedures?

A

In order to avoid damage to the recurrent branch of the medial nerve which is on the lateral portion of the hand.

14
Q

If a person injured their median nerve by trying to commit suicide by slitting their wrist, will they still have a functional thumb if they survive?

A

Partially. The abductor pollicus longus and adductor pollicus can still move the thumb because they are supplied by the ulnar nerve.

15
Q

Your patient tells you they have lost sensation on the medial part of their hands after riding their bike across the country. What has caused these symptoms?

A

Riding for a long time with your hands extended puts pressure on the hamate hooks which compresses the ulnar nerves.

16
Q

A person comes to see you after a long day of skiing complaining of minimal strength in their thumb when grabbing things and turning the key of their car. What likely happened when he was skiing?

A

He ruptured the collateral ligament of the 1st MCP joint. This usually is a result of hyperabduction of the MCP joint of the thumb.

17
Q

After being in a car accident a patient had lacerations in her forearm. She did not lose any motor function, only sensation to the dorsum of her hand. What nerve was injured and why was motor function unimpaired?

A

She injured the superficial branch of the radial nerve. This branches off from the radial nerve as does the posterior interosseous nerve which supplies suppinator and extensor function to the forearm. She still has function because the posterior interosseous nerve is still functioning.

18
Q

Why is a streptococcus infection in the forearm an urgent condition?

A

The bacteria can cause huge amounts of damage as it travels up the fascial compartments of the forearm.

19
Q

Your friend fell on an outstretched hand and denotes pain in his anatomical snuffbox. What portion of this broken bone is least likely to heal well?

A

The proximal portion of the scaphoid. It receives blood supply distally to proximally by the distal recurrent radial artery.

20
Q

What type of shoulder dislocation is a quarterback most likely to get?

A

Anterior. When throwing the shoulder is abducted and externally rotated. Getting hit from behind can push the head of the humerus anterio-inferiorly and dislocate the shoulder.

21
Q

What elbow injury is common in kids while being swung by their parents as they walk? How is this fixed?

A

Subluxation and dislocation of the radial head. This occurs when the radius is pulled on while the arm is pronated and the distal annular ligament is torn. The radius is put back into place by suppinating the child’s arm while flexed at the elbow.

22
Q

A person slips on ice and falls on an outstretched hand. They did not break their scaphoid. What is the most common forearm fracture?

A

Colles fracture. It is a complete fracture of the distal 2cm of the radius.

23
Q

A patient has been having problems with flexion of his hand. What muscles would you beef up to help him with this action?

A

Interossei (MCP joint flexion), Flexor Digitorum Superficialis (PIP joint flexion), Flexor Digitorum Profundus (DIP joint flexion), Thenar (Thumb MCP joint flexion), and the Flexor Pollicus Longus (Thumb PIP joint flexion).

24
Q

A patient has been having problems with extension of his hand. What muscles would you beef up to help him with this action?

A

Extensor Digitorum Communis (MPC joint extension), Interossei (PIP and DIP joint extension), Extensor Pollicus Brevis (Thumb MPC joint extension), and the Extensor Pollicus Longus (Thumb PIP joint extension).

25
Q

What muscles of the hand can act in flexion and extension?

A

Interossei and Thenar muscles.

26
Q

Will a nerve injury involving the posterior portion of the supinator cause more or less damage than a nerve injury involving the anterior portion of the supinator?

A

Less. The nerve enters the anterior portion of the supinator and exits on the posterior portion.

27
Q

Why would you think that the trapezium may have originally been a metacarpal?

A

The growth plate of the metacarpal of the thumb is located proximally where all of the other finger metacarpals are located distally with the phalynx metacarpals located proximally.

28
Q

What kind of motion do you have when extending the wrist?

A

Radio-carpal and lunato-capitate motion

29
Q

What causes the scaphoid to commonly break at the waist when someone falls on an outstretched hand?

A

Radioscaphoid capitate ligament

30
Q

A patient comes to see you with a broken pinky and ring finger. She says she will still probably be okay to do all normal activities because these are the smaller fingers of the hand. Is she right?

A

No. The pinky and the thumb are the most flexible fingers of the hand and allow for grabbing of things.

31
Q

A patient is having difficulty flexing his finger but has not torn any tendons. What else could be torn that make it difficult for him to flex his fingers?

A

The annular ligaments around the intermediate and proximal phalanges. These make up the pulleys necessary for finger flexion.

32
Q

What muscles are atrophied when you diagnose a carpal tunnel patient with thenar atrophy?

A

Abductor pollicis brevis, flexor pollicis brevis and opponens pollicis.

33
Q

What muscles are atrophied when you diagnose someone with hypothenar atrophy?

A

Abductor digiti minimi, flexor digiti minimi brevis and opponens digiti minimi

34
Q

When you pinch your girlfriend what muscles are making her squeal?

A

Adductor pollicis and 1st dorsal interosseus muscle

35
Q

What deep muscles of the hand abduct the fingers? Adduct?

A

DAB (dorsal interossei) and PAD (palmar interossei)

36
Q

A patient is having trouble with flexion of all finger joints. What muscles are weak at each joint?

A

DIPJ = FDP, PIPJ = FDS, MPJ = IO

37
Q

A patient is having trouble with extension of all finger joints. What muscles are weak at each joint?

A

DIPJ = IO, PIPJ = IO/EDC, MPJ = EDC (extensor digitorum communis)

38
Q

Why can you also get a patient’s pulse on the dorsal side of the hand?

A

The radial artery dives into the anatomical snuffbox deep to the tendons as it forms the radial side of the deep palmar arch.

39
Q

What arteries would you tie off most proximal to your incision if you cut the superficial palmar arch?

A

The ulnar and radial arteries. These form the superficial palmar arch. Note the ulnar artery will be most superficial.

40
Q

What major muscles will still work if someone has a cut to the ulnar nerve?

A

Abductor pollicus brevis (median), flexor pollicis brevis (median), opponens pollicus (median) and the radial side of the 1st three lumbricals (median).

41
Q

During a routine exam of your patient you notice that one leg is longer than the other. What could this condition be called if it was due to the hip?

A

Coxa vara = if the angle between femur shaft and head has decrease and shortened the leg. Coxa valga - if the angle between femur shaft and head has increased and lenthened the leg.

42
Q

A wide receiver jumps up to receive a pass and gets hit with a helmet right in the hip on the way down. The trainer says he has a hip pointer. What happened to him to cause this pain?

A

The impact probably ruptured capillaries in the sartoriius when it was compressed on the anterior superior iliac spine (ASIS)…forming a contusion.

43
Q

A man comes to see you with a “pulled groin” after horseback riding. What muscle was likely pulled?

A

His adductor longus. This muscle remains flexed throughout most of the duration of a horseback ride to keep the rider from falling off.

44
Q

Your cardiologist says he wants to do an angiogram to look at your left heart. Through what vessel will he go through? What if he wanted to look at your right heart?

A

Femoral artery = left heart. Femoral vein = right heart

45
Q

You are bleeding profusely after a gunshot wound to the anterior thigh. Where should the medic put pressure to control your bleeding?

A

It is possible that the bullet ruptured the profunda femoral artery. In this case, you need to compress the femoral artery by compressing it on the psoas major and superior pubic ramus.

46
Q

A 45 year old female comes to see you for a tender bump inferior and lateral to the pubic tubercle. You diagnose her with a femoral hernia. What path did the intestine have to take to get into the femoral triangle where it could bulge out?

A

It had to pass into the femoral ring, through the femoral canal and out the saphenous opening where it is now bulging outwards.

47
Q

A 25 year old male comes to the ER after his leg was crushed in a construction accident. Physical exam shows decreased temperature, sensation and pulse in his distal lower extremity. Why does this patient need surgery ASAP?

A

Compartment syndrome. The muscles of the lower extremity are enclosed by fascial compartments. When trauma causes bleeding in muscle, pressure increases in the compartments and compresses neurovascular structures. A fasciotomy must be done to relieve the pressure and save the neurovascular structures.

48
Q

How do varicose veins form?

A

Due to old age, lots of standing or whatever else, the veins in the leg expand and the valves no longer function. Blood pools in these veins as a result.

49
Q

During removal of cancerous lymph nodes from the pelvis the surgeon accidentally nicks a nerve. After the surgery the patient can no longer adduct his hip. What nerve was likely nicked in the procedure?

A

The obturator nerve. It innervates the adductor longus, adductor brevis, adductor magnus, external obturator and gracilis.

50
Q

What composes the border and floor of the femoral triangle.

A

The triangle is composed of the inguinal ligament, sartorious and adductor longus. The floor is composed of the pectineus and iliopsoas.

51
Q

A 92 year old patient comes to see you with warmth, swelling and erythema in his thigh. You suspect deep venous thrombosis, but he is still fairly active. If inactivity is ruled out, what else could cause DVT?

A

Weakening of muscle fascia reduces the musculovenous pump, can cause blood to pool and form clots.

52
Q

Why is a patient with a femoral hernia not really at risk for a nerve compression injury?

A

The femoral nerve is not located in the femoral sheath.

53
Q

A 45 year old patient had his broken hip fixed after a car accident. After 9 months of hip pain, he gets an X-ray that shows reabsorption of the femoral head. What artery was likely compromised during the surgery or in the accident?

A

Posterior circumflex femoral artery

54
Q

A 65 year old man has problems standing up out of a chair. He walks normally but has difficulty climbing stairs. What muscle has likely been injured?

A

Gluteus maximus. 75% of gluteus maximus inserts on the IT band.

55
Q

You do a hip assessment on a patient and they have a positive Trendelenburg test. You suspect nerve injury, what is causing his test to be positive? What other pathology could be present if it is not a nerve injury.

A

The superior gluteal nerve supplies the gluteal muscles. These muscles keep the pelvis elevated when one leg is not on the ground. His test is positive because the gluteal muscles on the leg he is standing on cannot keep the pelvis elevated and the pelvis dips on the side he is not standing on. This test can also be positive with greater trochanter fractures and hip dislocations.

56
Q

What contributes to wallet sciatica?

A

The wallet pushes on the piriformis muscle which compresses the sciatic nerve.

57
Q

A laboring pregnant woman decides that she wants a nerve block during labor. What nerve would you block?

A

Palpate the ischial spine where the sciatic nerve comes through the foramen and around the sacrospinous ligament.

58
Q

Why might one person present with hemorrhoids that bleed and another with ones that don’t bleed at all? Which one will have more pain?

A

Internal hemorrhoids are veins that break through the mucosa of the anal canal and bleed, but hurt less because they are in the visceral region. External hemorrhoids are veins that are covered by skin and don’t bleed, but hurt more because they are in the somatic region.

59
Q

At what point do you have to consciously make an effort to not poop you pants?

A

At the pectinate line. This line separates somatic from visceral muscle, visceral being more interior in the anal canal.

60
Q

You are watching a new baby and it never passes its first stool. What could be going on here?

A

Imperforate anus

61
Q

In what disease do you have to manually dilate the anus in order to pass stool.

A

Hirshsprung’s disease

62
Q

What transmits sensation to your butt when someone pinches your butt?

A

Superior, middle and inferior cluneal nerves.

63
Q

Two patients come to your clinic after a car accident with hip injuries. They both have their hip flexed but one has it adducted and internally rotated and the other has it abducted and externally rotated. How do the dislocations of their hips differ?

A

Posterior dislocation = hip adducted and internally rotated. He will also have a shorter leg. Anterior dislocation = hip abducted and externally rotated.

64
Q

What ligaments contribute to the formation of the greater and lesser sciatic foramina?

A

Sacrospinous ligament = lesser sciatic foramen. Sacrotuberous ligament = greater sciatic foramen.

65
Q

What ligaments contribute to the stability of the hip?

A

Iliofemoral, ischiofemoral and pubofemoral ligaments.

66
Q

What are the anatomical terms for someone who is knock kneed? Bowl-legged?

A

Genu varum= bowllegged , genu valgum= knock kneed

67
Q

What causes patellar-femoral syndrome?

A

Increased femoral anteversion

68
Q

What is the sole muscle in the anterior compartment of the thigh not innervated by the femoral nerve?

A

Psoas. It is innervated by the anterior rami of L1,L2 and L3.

69
Q

What is the sole muscle in the medial compartment of the thigh not innervated by the obturator nerve?

A

Adductor magnus. It is innervated by posterior branch of the obturator nerve and the tibial nerve.

70
Q

Which posterior compartment of the thigh is the sole muscle not innervated by the tibial compartment of the sciatic nerve?

A

Short head of the biceps femoris. It is innervated by the fibular compartment of the sciatic nerve.

71
Q

6 weeks after hip surgery a patient comes to see you with hip pain. Imaging shows resorption of the femoral head. What blood supply was likely nicked during his procedure?

A

The medial circumflex femoral artery.

72
Q

What muscles would lose function if you tore your pes anserine ligament?

A

Gracilis, Sartorious and Semitendonosis

73
Q

What portion of the meniscus is the best place to tear if it has to?

A

Around the periphery. This is where the blood supply is. There is no blood supply in the interior.

74
Q

A patient comes to see you after a football game complaining of knee pain after hearing a pop. You suspect an ACL tear. What tests can you do to confirm your diagnosis?

A

Lachman test, Anterior drawer test. These both test to see if the tendon will prevent anterior movement of the tibia.

75
Q

Why do some women experience anorectal incontinence after giving birth?

A

The pudendal nerve gets stretched and damaged.

76
Q

How does defection occur in a stepwise fashion?

A

Your body senses the colon is full and contraction of abdominal muscles increases intra-abodominal pressure. The external/internal anal spincters and puborectal sling relax. The rectal musculature contracts, the rectum and colon descend and feces are discharged.

77
Q

What are OB/GYN docs checking that need to be 10cm apart during labor? What are they checking before someone gets pregnant to see if they could possible do a vaginal delivery?

A

Laboring = distance between ischial spines. This is the most narrow part of the pelvis through which the baby’s head must pass and ligaments stretch during labor. Prepregnancy = distance between pubic symphysis and sacral promontory, this distance cannot change and will determine if you can have a vaginal delivery.

78
Q

A 39 year old female comes to see you with hip pain after moving into her new two story home. She said she was moving boxes up and down stairs all day. She says her pain hurts most with abduction and lateral rotation of the hip and it runs down to her tibia. What caused this pain?

A

Friction rubbing of gluteal tendons rubbing on the trochanteric bursa causing trochanteric bursitis.

79
Q

A 58 year old man tries to kick off after scoring a touchdown at his neighborhood’s yearly turkey bowl. He falls down after kicking, grabbing the back of his thigh, writhing in pain. From what bone did a tendon likely tear away from?

A

The ischial tuberosity. This is where all of the hamstring muscle attach and hamstring avulsions often occur when kicking or running hard.

80
Q

A 19 year old private is being operated on after receiving a gunshot wound to the medial buttock. After his surgery he can no longer extend his thigh or flex his leg. What happened either from the gunshot wound or the surgery?

A

Any wound to the medial buttock yields the patient susceptible to damage to the sciatic nerve, which provides innervation to the hamstrings. This patient has no hamstring function and likely had a damaged sciatic nerve.

81
Q

A 40 year old marathon runner comes to see you with knee pain around his patellar ligament. What is causing this pain?

A

It is likely an imbalance in the quadriceps muscles that cause chondromalacia patellae.

82
Q

When you tap a patients patellar tendon testing for reflex, where does signal go immediately after you tap?

A

Up the femoral nerve to the L2-L4 nerve roots and back down the femoral nerve causing the quadriceps to contract

83
Q

What surgery could you do to fix someone with non-functional external anal spincters?

A

Gracilis transplant. It is a minimal adductor of the thigh and losing it will not really affect anything.

84
Q

A patient comes to see you two years after a patellar tendon rupture complaining of frequent dislocation of the patella and pain while running. Why might his patella always dislocate laterally? What is causing his pain while running when it’s not dislocated?

A

It almost always dislocates laterally, on top of that, he might have atrophy of the vastus medialis, which holds the patella medially, and can predispose one to patella femoral syndrome.

85
Q

What three structures are likely to tear if you get hit in the knee while planted on that foot during a sprint?

A

The “unhappy triad”. ACL, MCL and posterior horn of the medial meniscus

86
Q

A patient comes to the ER after a car crash complaining of knee pain after his tibia collided violently with the dash of the car. What ligament was likely ruptured?

A

PCL

87
Q

A 65 year old man comes to see you complaining of decreased range of motion in his knee. There is no specific incident that caused it and it’s gotten worse over the past few months. You notice a large bump on the backside of his knee extending into his calf. What is your diagnosis?

A

Popliteal cyst

88
Q

What type of bursitis would you expect a house maid to have? A clergyman? A person with a distal femur fracture?

A

House maid = prepatellar bursitis. Clergyman = infrapatellar bursitis. Fracture = suprapatellar bursitis

89
Q

What is the first thing you should consider when someone comes in with a distal femur fracture?

A

Did they rupture their popliteal artery?

90
Q

How could you get around a popliteal artery rupture in a patient?

A

Bypass via the genicular arteries

91
Q

What is a milder form of anterior compartment syndrome in the leg?

A

Shin splints. People who live sedentary lives and suddenly exercise cause the muscles to become inflamed and pressure builds up within the fascial compartments of the leg.

92
Q

A patient comes into the ER after getting hit by a car. There is a laceration going through his popliteal fossa. How might you check to make sure his tibial nerve is still in tact?

A

Plantar flexion and sensation on the soles of the feet.

93
Q

A patient comes to see you after her knee dislocation was fixed complaining of difficulty walking and loss of sensation on the anterolateral portion of her leg and dorsum of her foot. On physical examination you note a high steppage gate. What nerve was likely injured when she dislocated her knee?

A

Common fibular nerve. Injury to this nerve results in loss of innervation to the anterior and lateral compartment of the leg, thus eliminating ability to dorsiflex and evert the foot. This woman has the typical clinical sign of foot drop.

94
Q

A 30 year old mom comes to see you after a day of skiing complaining of pain in her first webbed space of her foot. What is causing this pain?

A

Deep fibular nerve entrapment by the ski boots compressing the extensor retinaculum and extensor hallicus brevis on the deep fibular nerve.

95
Q

What nerve is paralyzed in absence of a calcaneal tendon reflex?

A

S1 or S2

96
Q

A young basketball player you have seen many times for calcaneal tendinitis walks into your office with his foot rotated laterally, using his midfoot to push off as he goes. What do you suspect he is here to see you for?

A

Calcaneal tendon tear

97
Q

A patient complains of leg cramps in the posterior compartment while walking that disappear after rest. What is this condition called and how would you assess the patient?

A

This is intermittent claudication that can be caused by occlusion of the posterior tibial artery and thus ischemia. You would have the patient invert their foot to relax the extensor retinaculum so you can check his posterior tibial pulse.

98
Q

What bone of the body is most likely to compound fracture?

A

Distal portion of the tibia. It is the weakest part of the tibia and is subcutaneous.

99
Q

Where would a patient lose feeling if you accidentally transected his superficial fibular nerve near the maleolus during and ankle surgery?

A

Much of the dorsum of the foot, excluding the 1st webbed space and the lateral aspect of the foot

100
Q

Transection of what nerve would result in loss of sensation in the lateral dorsal aspect of the foot?

A

Sural nerve

101
Q

One of your duties as a resident is to insert a cannula for blood administration prior to big surgeries. One day, a post-operative patient complains of pain and numbness along the medial border of his foot. What structure might you have cut?

A

The saphenous nerve. It runs next to the saphenous vein which is often used in cut downs for surgeries. The saphenous nerve innervates the medial border of the foot.

102
Q

A high school basketball player severely rolls her ankle. You find that she has a fracture and swelling in her high ankle. What bone is likely fractured and what ligaments are likely torn?

A

The lateral malleolus of the fibula is often fractured in ankle inversion injuries. The talofibular ligament is the most susceptible to tear in ankle inversion injuries…the calcaneofibular ligament can sometimes tear also.

103
Q

While playing tennis, you misstep and roll your ankle pretty bad. You have lots of swelling and pain in your lower ankle. If there was a fracture, what would it likely be?

A

An avulsion of the 5th metatarsal from tearing away of the fibularis brevis tendon

104
Q

What happens when someone has a Pott fracture-dislocation of the ankle?

A

Often the foot is everted severely enough that the medial ligament tears off the medial malleolus. This causes the talus to move laterally and break the lateral malleolus. The posterior portion of the distal tibia can break also if the tibia shifts forward.

105
Q

What is the foot’s version of carpal tunnel syndrome?

A

Entrapment of the tibial nerve by the flexor retinaculum. It is enclosed in a small space between the medial malleolus and the calcaneous that can be compressed by other tendons.

106
Q

What causes bunions?

A

Hallux valgus. The 1st metatarsal deviates laterally, displacing the sesamoid bones. This causes pain, inflammation and formation of bursas. These bursas are bunions.

107
Q

How might someone acquire flat feet?

A

Lots of standing and weight gain can cause loss of support of the talus by the calcaneonavicular joint. The talus drops down, lengthening the medial longitudinal ligament and causing flat feet.

108
Q

What ligaments and tendons tend to be shorter in a child with clubfoot?

A

The tibionavicular ligament, extensor hallicus longus, extensor digitorum longus and anterior tibialis tendons.

109
Q

A 27 year old female who enjoys running presents to your office with medial foot pain that is the worst when she gets out of bed in the morning. It gets better with movement and worse after rest. Palpation of what bone is likely to cause most tenderness in this patient?

A

Medial tubercle of the calcaneous. This is plantar fasciitis

110
Q

A 19 year old runner comes in complaining of pain and tingling on the medial side of his foot while running. What is causing his symptoms?

A

Medial plantar nerve compression

111
Q

Where can you best palpate the dorsalis pedis artery of the foot?

A

Lateral to the extensor hallicus longus tendon as it crosses the midfoot.

112
Q

Where would you expect to find swollen lymph nodes from an infection of the lateral foot? The medial foot?

A

Lateral = popliteal and inguinal. Medial = inguinal only

113
Q

A 65 year old male comes in complaining of pain on dorsiflexion and plantar flexion of his ankle. What joint is likely arthritic? What if he had pain with inversion and eversion? With mid foot movement while walking?

A

Inversion/eversion = talocalcaneal joint. Dorsiflexion/plantar flexion = talocrural joint. forefoot motion = talonavuncular joint

114
Q

Why can’t you cut the flexor retinaculum for someone with pain in their 1st webbed space?

A

It stabilizes all of the flexor tendons of the foot and would render them nonfunctional if cut

115
Q

What protects the bones if the foot from impact damage while walking?

A

Plantar aponeurosis

116
Q

What nerve is causing pain when you have plantar fasciitis?

A

Calcaneal nerves

117
Q

What bones are likely to break in your foot if you jump from a rooftop?

A

Calcaneus and 5th metatarsal, these are the weight bearing bones in the arch of the foot
