Anatomic variation of the trapeziometacarpal joint stabilizing structures is one of the concepts proposed to explain the pathogenesis of trapeziometacarpal arthritis. We undertook this study to test the hypothesis that septation of the first extensor compartment or variation of the abductor pollicis longus (APL) tendon (supernumerary insertions) are more(More)
Using data from our MRI study, we found that a tunnel oriented 50° externally rotated and 60° cephalad would better connect the fibular collateral ligament (FCL) insertion to the popliteofibular ligament (PFL) insertion as compared to a traditional anterior-to-posterior (A–P) fibular tunnel. The purpose of this study was to test that finding in a cadaver(More)
OBJECTIVE Through the evaluation of randomized clinical trials using a statistical methodology consisting of comparative assessment, we sought to determine the conditions under which allopurinol was a protective agent for patients undergoing coronary artery bypass grafting (CABG). METHODS The medical literature was searched for all human clinical trials(More)
The relationship of proximal tibial morphology to the presence of femoral osteochondritis dissecans (OCD) lesions is unknown. This radiographic study tested the null hypothesis that knees with unilateral medial or lateral OCD lesions would have no difference in the slope of their medial, lateral, or posterior tibial plateau compared with unaffected knees.(More)
BACKGROUND Aseptic loosening of the femoral stem remains a significant reason for revision in total hip arthroplasty (THA). Although stem fixation methods have changed over time, there is relatively little evidence supporting cemented or uncemented stems as more durable constructs. QUESTIONS/PURPOSES We examined whether there was a difference in survival(More)
