SUMMER 2008 BETA 31 Trauma : “I can’t remember anything after the first few words she said: ‘I’m sorry to tell you that your test results came back positive.’ After that, it was all just a blur of sounds and images—the traffic outside, my heart beating, the look on her face. Everything was moving in slow motion. I just kept hearing those five words echoing in my head: ‘Your test came back posit...

Thirty shoulders, in 20 patients, which had undergone core decompression for symptomatic avascular necrosis of the humeral head were reviewed 2 to 14 years later (average 5.6). Twenty-two showed good or excellent clinical results; the other eight shoulders had required arthroplasty. All 14 shoulders with stage I or II radiological changes (Ficat and Arlet 1980) at operation had good or excellen...

BACKGROUND Although scapular malpositioning is commonly associated with rotational deficits and risk of injury, modifiable causes of such malpositioning in overhead athletes are not well described. PURPOSE/HYPOTHESIS The purpose of this study was to examine the scapulothoracic profile of adolescent baseball players, specifically, pectoralis minor (PM) length. We hypothesized that PM would be ...

Dysregulated extracellular matrix (ECM) metabolism may contribute to vascular remodeling during the development and complication of human atherosclerotic lesions. We investigated the expression of matrix metalloproteinases (MMPs), a family of enzymes that degrade ECM components in human atherosclerotic plaques (n =30) and in uninvolved arterial specimens (n=11). We studied members of all three ...

BACKGROUND Posttraumatic anterior shoulder instability is associated with anterior glenoid bone loss, contributing to recurrence. Accurate preoperative quantification of bone loss is paramount to avoid failure of a soft tissue stabilization procedure as bone reconstruction is recommended for glenoid defects greater than 20% to 27%. QUESTIONS/PURPOSES We determined whether radiography, MRI, or...

HYPOTHESIS Traumatic inferior shoulder dislocation (luxatio erecta) injuries are rare, comprising less than 0.5% of all shoulder dislocations. Few cases have been reported, and the outcome of treatment has been ill defined. MATERIALS AND METHODS Between 1968 and 2000, 18 patients (20 shoulders) with luxatio erecta were evaluated at our institution. Two patients (2 shoulders) were lost to foll...
