Applied Anatomy and Clinical Correlations — Flashcards

Musculocutaneous nerve injury commonly occurs in the setting of: - Trauma (e.g., _____ dislocation) - Bullet shot to the anterior arm - Strenuous upper extremity exercise (e.g., baseball pitching)

In the elbow there are three joints, these being:- _____ Joint- Ulnohumeral Joint- Proximal Radioulnar Joint

Injury to the _____ nerve (C8-T1 (nerve roots)) commonly occurs due to:- fracture of the medial epicondyle of humerus "funny bone" (proximal lesion) - fractured hook of hamate (distal lesion) (from fall on outstretched hand - "FOOSH")

The _____ (rotator cuff muscle) is innervated by the axillary nerve.

Before the median nerve enters the wrist / hand within the _____, it travels through the forearm between the flexor digitorum superficialis and the flexor digitorum profundus

Claw hand deficits are _____ pronounced in proximal lesions

Hint: (more/less)

Injury to the _____ nerve (C5-T1) Causes: - Midshaft fracture of the humerus - Compression of the axilla Clinical features: - Wrist drop - Finger drop

The _____ (bone) (palpable in the anatomic snuff box) is the most commonly fractured carpal bone.

_____ bursa continues proximally extending into forearm 2.5cm proximal to flexor retinaculum

A lesion to the #_____ cord would result in wrist drop, paralysis of the deltoid, and impairment of internal rotation of the humerus
