BACKGROUND Frozen shoulder is a debilitating condition characterized by gradual loss of glenohumeral motion with chronic inflammation and capsular fibrosis. Yet its pathogenesis remains largely unknown. We hypothesized that the subacromial bursa may be responsible for the pathogenesis of frozen shoulder by producing inflammatory cytokines.

BACKGROUND The clinical and radiological outcomes of revision total knee arthroplasty with a cemented posterior stabilized (PS), condylar constrained knee (CCK) or a fully constrained rotating hinge knee (RHK) prosthesis were evaluated. METHODS This study reviewed the clinical and radiological results of 36 revision total knee arthroplasties with a(More)
We measured the change of the center of hip rotation after the revision of acetabular loosening using an acetabular reconstruction ring and an impaction allogenic bone grafting. Thirty-five revision total hip arthroplasties were performed. The average follow-up was 3.8 years. Horizontal distance was changed from 34.01±10 mm preoperatively to 41.07±6 mm at(More)
Defects of the femoral shaft (15%, 20%, 25%, and 30% of the femoral length) with intact periosteum were made in young rabbits to investigate differences in union time. The mean union time was 7.3, 7.1, 7.4, and 7.0 weeks, respectively and there was no significant difference ( >0.05) between the groups. The mean healing indices were 6.7, 4.6, 3.9, and 3.1(More)
OBJECTIVE To compare results between vascularized fibular grafting and internal bone transport for large bone defects of the femur. DESIGN Retrospective review of patients. SETTING University teaching hospitals. PATIENTS This study included 37 patients with femoral bone loss: 20 patients were treated with internal bone transport and seventeen patients(More)
We describe a case of Charcot ankle arthropathy in a 43-year-old male patient who underwent revision surgery for tibiotalocalcaneal arthrodesis with a retrograde intramedullary nonvascularized fibular graft. After 3 months of postoperative stabilization with a ring external fixator, successful radiographic union was identified. The findings obtained at 33(More)
The purpose of this study was to identify the optimal position for a precontoured-locking plating (PHILOS®) of the proximal humerus in Asians in terms of conformity and to determine the prevalence of screw exits in the position of the highest conformity. Twenty adult humeri and 14 cadaveric shoulders were included in this study. After placing the(More)
