-
-and flexor retinaculum (laciniate ligament),

95
Q

** Ulnar nerve entrapment - signs on exam**

A

-Percuss or pressure ulnar groove (Tinel test)
-Percuss over Guyon’s canal
-Sustained maximal elbow flexion x1min with wrist in neutral position OR
-Hypothenar atrophy
-Weak finger adduction eg pinch paper (catch little finger in pocket)
-Decreased sensation to pinprick and light touch in all ulnar territories

96
Q

** Ulnar nerve sites of entrapment **

A

-Cubital tunnel
-Ulnar tunnel /Guyon’s canal

97
Q

Causes of ulnar nerve entrapment

A

Cubital tunnel
- Elbow synovitis, osteophytes,
- Prolonged flexion
- DM

Ulnar tunnel
- Trauma, laceration
- Ganglion cyst
- Distal vascular anomalies
- External pressure (prolonged resting on flat surface eg anesthesia)

98
Q

Types of thoracic outlet syndrome

A

Vascular:
– Subclavian artery: ischemic sx
– Venous occlusion: edema, engorged superficial veins, thrombosis
-
-Neurologic
– Weakness of hand intrinsic muscles
– Sensory loss in ulnar distribution over hand/forearm

99
Q

Thoracic outlet syndrome test

A

Adson manuever - palpate radial pulse while inhaling, extending neck, turning head ipsilaterally (cervical rib) and contralaterally (scalenus anticus syndrome). Positive if pulse drops and symptoms reproduced

-Hyperabduction maneuver
-Costoclavicular maneuver

100
Q

Thoracic outlet syndrome Tx

A

-ROM, PT for posture
-Avoid hyperabduction
-Botox
-Surgery

-Refractory: Cervical rib or fibrous band resection

101
Q

** C7 injury; What is the clinical presentation, motor deficit, Sensory deficit, reflexes. **

A

Posterior forearm pain, paresthesia of 3rd finger, might have neck pain

-Motor deficit: elbow and finger extension, wrist flexion

-Sensory deficit: 3rd finger

-Reflexes: decreased tricep reflex

102
Q

** RA patient comes in with numbness in hands – differential diagnosis (3)?
-Name 2 investigations?**

A

DDX:
-CTS
-Atlantoaxial instability +/- cord compression
-Peripheral neuropathy from vasculitis
-Raynauds
-
-Ix:
-NCS/EMG
-C spine XR
-Polyneuropathy workup: B12, TSH, A1C, SPEP

103
Q

**Patient with pain at groin, radiating to thigh and knee, burning sensation anterior thigh, hip ROM normal, SLR normal
-What nerve root is affected?
-Give one test to do on physical exam and how would you do it?

A

-Test:
-L2-L3 nerve root: Femoral nerve stretch test; patient lies prone, knee flexed to 90 degrees, then hip passively extended; reproduction of anterior thigh pain is positive test
-Meralgia: direct pressure over nerve where it exists pelvis
-Motor/reflexes should be normal
-Typical symptoms include burning dysesthesias and pain over the anterolateral thigh, unaffected by hip rotation or straight leg raise. In some patients, these symptoms may be elicited by performing Tinel’s test at the site of entrapment.

104
Q

Meralgia paresthetica pathology, causes, and symptoms

A

Lateral femoral cutaneous nerve compression at inguinal ligament medial to ASIS → burning pain and dysesthesia over anterolateral thigh

-Cause
–Obesity,
–Preg
–Trauma
–Surgical injury (eg appendectomy
–Tight belts
–DM
