Arthroscopic Acromioplasty: Discussion and Outcomes:

Discussion:     – objective good to excellent results may be achieved in over 70% of patients, and subjective satisfactory results are achieved in over 90% of patients;     – shoulder arthroscopy is indicated in cases of impingement syndrome and questionable rotator cuff tear repair, since the shoulder scope will be able to determine the status of … Read more

Arthrodesis of the Shoulder

– See: Brachial Plexus Injury – Indications: – shoulder paralysis: – may include paralytic dislocation or combined rotator cuff / deltoid paralysis (in which case shoulder arthroplasty would be contra-indicated); – as a requirement for shoulder fusion, the muscles of forearm and hand need to be functional as do the serratus anterior and trapezius; – the … Read more

Arthroplasty of the Shoulder

– Discussion: – Total Shoulder Arthroplasty:    (considerations: hemiarthroplasty vs TSA) – Reverse arthroplasty   – Indications: – indicated for end stage DJD or RA shoulder involvement; – contra-indications to shoulder arthroplasty include combined rotator cuff / deltoid paralysis and recent joint infection; – in these rare circumstances, arthrodesis may be considered; – may occur as … Read more

Arterial Development of the Limbs

(See also: Adult Upper Limb Arteries) Discussion: Upper Limb Development subclavian artery projects into the early upper limb bud & forms subclavian-axillary-brachial  trunk; its distal portion becomes interosseous artery that initially supplies plexus of arteries in the primitive hand; branch of trunk artery, median artery, temporarily replaces interosseous artery in supplying the hand; subsequently, ulnar … Read more

AP of Shoulder: in the scapular plane

– See:       – Anterior Dislocation       – Posterior Dislocations: – Discussion:     – note: w/ true AP of shoulder there should be no overlap of the humerus over the glenoid; – Greater Tuberosity and Acromio Humeral Interval;     – AP in ext. rot. brings greater tuberosity into clear … Read more

AVN and Salvage of Talus Fractures

– See: – Radiographic Evaluation – Blood Supply to Talus- Discussion: – may occur following talar neck fractures or may be atraumatic (from SLE, diabetes, MS ect); – absence of subchondral bone atrophy in talar dome on x-ray after 6 weeks following fracture implies AVN (see Hawkins Sign); – however,  there is not direct correlation between development of AVN and … Read more
