Clinical Anatomy Upper Limb Flashcards
2 joints of shoulder girdle
Glenohumeral + Acromioclavicualr
Muscles of rotator cuff
supraspinatus, infraspinatus (alos teres minor) and subscapularis
Causes of impingement
Tendonitis, cuff tear, subacromial bursitis, osteophytes from AC joint (can inject subacromial space)
In anterior dislocation what commonly detaches
labrum (lower part is called Bankart lesion)
Anterior dislocation of shoulder may impinge on
Axillary nerve (at quadrangualr space) Brachial plexus + even axillary artery
Adhesive capsulitis
Frozen shoulder, Global loss of ROM. May inject GH joint in painful phase.
Nerve of anterior compartment of upper arm
Musculocutaneous nerve (also supplies later forearm)
Nerve of posterior compartment of upper arm
Radial nerve
Radial nerve supplies all …
extensors of upper limb (damage = wrist drop)
In a humeral shaft fracture what is susceptible to injury
Radial nerve
Extensor origin of elbow =
lateral epicondyle (tennis elbow)
Flexor origin of elbow =
medial epicondyle (golfer’s elbow)
Supracondylar fracture (just above elbow) may cause …
brachial artery occlusion + median nerve injury (also radial and ulnar nerves)
Nerve of anterior compartment of forearm …
All median Nerve except Flexor Carpi Ulnaris + Flexor Digitorum Profundus (ulnar nerve)
Nerve of Posterior compartment of forearm..
Radial nerve (any extensor in the upper limb)
