Q

Wartenberg’s Sign

A

Position of abduction in the pinky. The ulnar nerve controls abduction and adduction of the pinky but with abduction the extensor digiti minimi and branch to pinky from EDC also play a part and are controlled by radial nerve. To do this test you have palm on a table and have them extend the fingers then abduct and adduct (they won’t be able to adduct).

Q

Anterior Interosseous Nerve vs Median Nerve

A

Median nerve travels between the 2 heads of the pronator teres and then gives rise to AIN (the median nerve continues down as well). The median dives between the FDS and FDP.

AIN: FPL, Radial 2 FDP, Pronator quadratus.

Median: Rest of the wrist/finger flexors (except FCU and ulnar FDP); 1st 2 lumbricals; thenar muscles; sensation to median nerve distribution.

Median nerve comes off lateral and medial cords.

30
When does peel back mechanism occur?
Cocking phase of throwing
31
Putti-Platt Procedure
Tightening the anterior capsule and subscapularis with subsequent accepted loss of ER to increase stability of shoulder. Not used for baseball players because of the loss of ER.
32
Fat-Pad Sign
Also called “sail sign”. Describes the elevation of the anterior fat pad. It’s usually concealed in the coronoid fossa. Happens with increased swelling or a fracture (usually condylar in children and radial head in adults).
33
Capsular Shift
Capsule and ligaments tightened to increase shoulder stability. This has fallen into favor for MDI and will maximize stability but allow full return of ROM.
34
Volkmann’s Contracture
Acute ischemia to the muscle fibers of the forearm flexors >> extensors.They become fibrotic and shortened and leads to contracture. This is caused by obstruction of the brachial artery near the elbow due to improper/poor fitting of cast; supracondylar fractures; crush injuries; and compartment syndromes. Position on arm: Wrist flexion/pronation, thumb adduction, MCP extension, IP flexion
35
Runner’s Hematuria Prevention
1. Keep a small amount of urine in the bladder before run 2. Avoid high doses of NSAID’s (they have blood-thinning effects and can exacerbate problem)
36
Runner’s Hematuria Management
Usually clears up within hours/days. Regardless, recommend sending to PCP to investigate possibility of serious pathology (kidney stones, cancer, etc.)
37
Diuresis
Water loss at the kidneys
38
Wound healing intention?
Primary Intention = when wound edges are approximated (sutures, staples, glute) Secondary Intention = wound edges cannot be approximated and wound needs to heel from the bottom Tertiary Intention = combination of both, wound cannot be stitched up immediately but can after awhile
39
Time delay allowed to close wound to have minimal risk for infection?
4-6 hours so wound edges aren’t too inflamed, colonized, or necrotic.
40
Management of hypoglycemia?
Mild: management can be treated with absorbed glucose, hard candy, sugared beverage, fruit juice. Severe: Usually has mental status changes, autonomic changes, and/or collapse. Needs to be treated with subcutaneous/intramuscular injection of glucagon (kits for home administration are available and should be available at athletic events for athletes with DM1).
41
Athlete Collapses With No Prodromal Symptoms?
Cardiac collapse tends to be instantaneous with no symptoms prior to the collapse. If they have ventricular fibrillation they will hit the ground and no longer talk.
42
Sickling Collapse vs Heat Collapse
Sickling collapse usually occurs within first 1/2 hour on field and core temperature not greatly elevated.
43
Salter-Harris Fracture
A growth plate fracture of a long bone. Type 1: Fracture line runs straight across growth plate Type 2: Fracture breaks at an angle going through most of the growth plate and the metaphysis Type 3: Rare. Usually in distal tibia bone. Cuts vertically through epiphysis and then through part of physis (almost like a 90 angle) Type 4: Vertical/oblique line that goes through metaphysis, physis, and epiphysis. Type 5: Growth plate damage but no fracture. 1 = Straight 2 = M 3 = E 4 = ME 5 = Crush
44
How long to place in a sling after a shoulder dislocation?
3 weeks
45
After injury/surgery, what should total ROM for the throwing shoulder be compared to the other side?
Within 5% of total motion compared to the other side.
46
Noncontact and contact ACL injury rate for female vs male athletes?
2-6 times higher for noncontact. Equal injury rate for contact. The risk of subsequent contralateral ACL injury is higher in females vs males also.
47
Risky body positions during landing to tear ACL?
1. Extended knee 2. Flat foot 3. Offset body position
48
Risk factors for noncontact ACL injuries?
1. Joint laxity 2. Intercondylar notch width 3. BMI 4. Maximal knee flexion during landing 5. Initial and maximal knee valgus
49
Components of ACL injury prevention program that decrease rate of ACL injuries?
Components include: 1. Dynamic stretching 2. Strengthening 3. Functional balance 4. Agility 5. Plyometrics Lasts more than 10 minutes, 3x/week for at least 8 weeks. Should be continued in-season during warm up.
50
Risk factors found to predict development of PF pain in asymptomatic female adolescent athletes?
1. Knee valgus displacement during box-drop test 2. Early sport specialization
51
Differences in females (compared to males) with regards to cutting/jumping and ACL risk?
1. Females (adults/children) have higher knee valgus angles/moments during cutting, landing and squatting 2. The increased valgus angles/moments shown to be associated with ACL injury risk 3. Females have decreased hip flexion angles and greater knee flexion stiffness during cutting tasks 4. Greater hip adduction angles in females and positively related to knee valgus angles 5. Females are weaker (normalized to body weight) in hip strength, and quad/hamstring strength. 6. Females have different quad, hamstring, and gastroc muscle activation patterns than males.
52
Muscle strength and knee kinematics?
They are weakly to moderately related. This suggests that strength is not the only factor, other neuromuscular factors may be important
53
Female structural factors compared to males with regards to ACL?
1. Female ACL is smaller in length, cross-section, and volume (even after adjusting for body anthropometry) 2. Females have narrower/shallower notches (notch width is good predictor of size in men but not women; notch angle is good predictor of ACL size in women but not men) 3. Female ACL is less stiff and fails at a lower load (even after adjustment for anthropometry and ACL size).
54
Hormones and the females ACL?
Although there is no consensus in the literature, there have been studies correlating menstruation with ACL tears in women. Estrogen and progesterone receptor sites have been reported in human ACL cells. It has been proposed that levels of these hormones may have deleterious effects on the tensile strength of the ACL.
55
Position the knee usually is in during isolated ACL tears?
ER and valgus. This is counterintuitive because the ACL is only loaded in IR. This mechanism may be related to impingement of the ACL on the lateral wall of the intercondylar notch. A narrow notch would directly contribute to this mechanism.
56
Kohler Disease?
Idiopathic avascular necrosis of the navicular. Can take 2-3 years to return to normal.
57
Little league elbow?
Medial epicondyle apophysitis. The medial apophysis is the weakest structure on the medial side of the elbow.
58
Osteochondrosis vs osteochondritis
Osteochondrosis is a developmental disorder of the bones in children/adolescents where there is a disruption of blood supply to a specific area of bone, resulting in death of bone tissue (AVN is similar and can occur at any age). Osteochondritis is an inflammatory condition that affects the cartilage and bone in a joint, usually develops following injury/trauma.
59
Where does OCD happen more in the lateral elbow?
Capitellum > radial head
60

76
What to do if you find someone unresponsive?
Check ABC’s. Make a phone call to 911 as soon as possible and attach AED as soon as possible. One round of CPR is acceptable if there is no one to place a call to 911.
77
Good Samaritan Law
Applies in emergency settings only for when someone acts in good faith when someone is in imminent danger.

87
Arcade of Frohse
The arcade is formed by a fibrous band between the two heads of the supinator muscle. The deep branch of the radial nerve passes beneath the arcade.
88
Osborne’s Ligament
Osborne's ligament can be classified as the fibrous band bridging the two heads of the FCU (arises from humerus and goes to FCU). Osborne's ligament forms the roof of the cubital tunnel, an opening between the muscles through which the ulnar nerve passes.
89
HAGL Lesion
Humeral avulsion of the GH ligament (inferior). Usually occurs with arm being forced into abd/ER position.
90
ALPSA Lesion
Anterior labroligamentous periosteal sleeve avulsion. The anterior labrum rolls off the glenoid and backwards in a medial and inferior direction (like you’re rolling up a sleeve and going backwards towards the scapula).

97
Os Acromiale
Unfused acromial epiphysis. Usually ossifies from 18-25. This can project into the RTC outlet, decreasing total area, and is thought to be associated with RTC pathology.
98
RTC Repair Rehab?
Sling for 6 weeks. Early PROM (full ROM by 8-10 weeks) Isometrics at 3-4 weeks (isotonics 4-6 weeks) AAROM at 3-4 weeks (delaying abd for 6-8 weeks)

What clinical tests are most predictive of RTC tear?
Supraspinatus weakness Weakness in ER Impingement sign
100
What to do if the spine is not in a neutral position after neck trauma?
1. Try to realign the spine to minimize secondary injury to spinal cord 2. Don’t move the neck if any of the following occurs: - There is increased pain - Neurologic symptoms occur - Muscle spasm - Airway compromise - It is physically difficult to reposition spine - Resistance is encountered - The patient is apprehensive
101
How often should emergency action plans be rehearsed?
At least annually
102
During initial assessment, what findings heighten the suspicion of a potentially catastrophic cervical spine injury and require initiation of spine injury management protocol?
1. Blunt trauma and unconscious or altered level of consciousness 2. Neuro findings/complaints 3. Significant midline spine pain with or without palpation 4. Obvious spinal column deformity
103
If doing CPR during neck stabilization procedure, what should you do about rescue breaths?
Jaw thrust instead of head tilt technique.
104
Removing helmet or shoulder pads for neck injury?
Protective athletic equipment NEEDS to be removed prior to transportation to emergency facility. Needs to be done with at least 3 people present.
105
How to move supine athlete? Prone?
Supine: 8 person lift Prone: Need to use log roll PUSH technique (5 people)
106
Scoop Stretcher
Hinged at both ends to “scoop” the athlete so not needing to do log roll or lift and slide.
107
Securing head on spine board?
Head is always last part of body to be secured. ONce the head-immobilization device is placed to stabilize the head, tape or straps should be used to secure the head at 2 separate points of contact (chin and forehead)
108
Face Mask Removal
With 4 attachments, remove the 2 side straps first, folllowed by the top straps (so mask doesn’t rotate down onto throat) If one score gets stuck keep trying to remove the others and then have a tool to cut the mask.
