– Discussion: – see: elbow flexion contracture; – indicated for patients w/ loss of motion (out of functional range from 30 to 130 deg) due to anterior and posterior osteophytes; – PreOp Planning and Positioning: – patient is supine w/ bump placed under shoulder, and arm folded across chest; … Read more

– Discussion: – simple transverse frxs w/out comminution may have delayed healing which requires close observation to avoid distraction & angulation; – this is especially true if a gap exists at frx site which cannot be closed by non operative means; – Closed Reduction: – note these … Read more
– See: Three Part Fracture – Discussion: – includes large proximal fragment created by frx of surgical neck of humerus; – some capsular tissue is almost always retained on large head fragment ensuring its viability; – if head fragment is displaced anteriorly, greater tuberosity is usually frxed, whereas lesser tuberosity … Read more
– See: Three Part Fracture Dislocation and Four Part Fracture – Discussion: – tuberosity frag + displaced surgical neck fragment; – unstable shafts may be driven into mass of deltoid muscle & may be anterior to the proximal fragment; – poor bone contact will lead to delayed or nonunion in most cases; – subtypes: – greater … Read more
Discussion (see also: subacromial bursectomy) subacromial bursa is large synovial membrane which is adherent to undersurface of coracoacromial ligament, acromion, & delltoid laterally, an is adherent to rotator cuff & greater tuberosity; it envelops proximal humerus, & facilitates gliding of proxiaml humerus under coracoacromial arch References Synovial osteochondromatosis in the subacromial bursa. Subacromial/subdeltoid bursa abscesses. An overlooked diagnosis.

– Discussion: – these plates are used with 3.5 mm cortex screws; – their main application is for use with pelvic and acetabular frx; – they may be also used in fractures of the distal humerus (dorsolateral apect), the clavicle, and the calcaneus; – reconstruction plates have notches … Read more
– See: – Humeral Shaft Fractures in Children – Throwing Shoulder – Discussion: – most of these injuries are either Salter I or II fractures; – frx separations of proximal humeral epiphysis occur most often between ages of 11 and 15 years; – 80% of longitudinal growth of humerus occurs in proximal physis; – large … Read more
