Abdominal aortic aneurysms (AAAs) can cause aortoenteric fistulae (AEF). AEF can either be primary, arising from the aneurysm or other diseases, causing the aorta to erode into the bowel, or secondary, from previous aortic grafting. Primary aortoduodenal fistula (ADF) is a rare clinical entity that usually presents with gastrointestinal bleeding that can be(More)
The optimal treatment for displaced femoral neck fractures in elderly patients is a matter of controversy. Four surgical options are well supported in the orthopaedic literature: reduction with internal fixation, unipolar hemiarthroplasty, bipolar hemiarthroplasty, and total hip arthroplasty. Based on a review of the outcomes literature regarding treatment(More)
BACKGROUND During the 1990s, cost reduction programs were developed to decrease the hospital cost of total knee arthroplasty. The purpose of this study was to evaluate the impact of hospital cost reduction programs for total knee arthroplasty on patient outcome at our hospital. METHODS We evaluated 159 patients who had undergone unilateral primary total(More)
A painful arthritic knee with severe valgus deformity may be treated successfully with total knee arthroplasty using several techniques: constrained implant with lateral release, nonconstrained implant with lateral release and a thick tibial insert, or nonconstrained implant with lateral release and medial reconstruction. Eight patients with Type II valgus(More)
BACKGROUND Treatment for acromioclavicular (AC) joint pain may include distal clavicle excision (DCE). It is possible that DCE can disrupt the surrounding ligaments, leading to increased AC joint laxity. PURPOSE To determine the load to failure and stiffness of the AC joint after DCE and symmetric acromioclavicular joint resection (ACJR). STUDY DESIGN(More)
A prospective case series was undertaken to determine the incidence of os acromiale in patients presenting to an orthopedic clinic with shoulder pain during a 6-month period. Ninety-three shoulders in 88 consecutive patients were evaluated by history, physical examination, and radiographs. Radiographs included anteroposterior, scapular Y, and axillary views(More)
Degeneration and tearing of the long head of the biceps brachii tendon (LHBT) are common intra-articular findings, and surgical intervention including tenodesis or tenotomy is beneficial. A new arthroscopic shoulder technique may be performed through an anterior portal while one is viewing from a posterior portal: (1) Visualize the intra-articular biceps(More)
The goal of this study was to evaluate contact area and surface pressure as a result of different suture patterns in the treatment of anterior shoulder instability caused by a Bankart lesion. Loads were applied through the humeral head to the glenoid surface in the intact shoulder and after simple suture labral repair (n=10) and vertical mattress labral(More)
