BACKGROUND Open reduction and internal fixation is the treatment of choice for displaced intra-articular calcaneal fractures at many orthopaedic trauma centers. The purpose of this study was to determine whether open reduction and internal fixation of displaced intra-articular calcaneal fractures results in better general and disease-specific health(More)
We conducted a prospective, randomized, controlled trial to compare functional outcomes, complications, and reoperation rates in elderly patients with displaced intra-articular, distal humeral fractures treated with open reduction-internal fixation (ORIF) or primary semiconstrained total elbow arthroplasty (TEA). Forty-two patients were randomized by sealed(More)
OBJECTIVE Serial circulating tumor cell (CTC) counts have demonstrated predictive and prognostic value in patients with metastatic breast, colorectal, and prostate cancer. In a phase III study of pegylated liposomal doxorubicin (PLD) with trabectedin vs. PLD for relapsed ovarian cancer, we evaluated the correlation, if any, between numbers of CTCs and(More)
We randomised prospectively 44 patients with fractures of the shaft of the humerus to open reduction and internal fixation by either an intramedullary nail (IMN) or a dynamic compression plate (DCP). Patients were followed up for a minimum of six months. There were no significant differences in the function of the shoulder and elbow, as determined by the(More)
BACKGROUND Microfracture, the standard of care, is recognized to be an incomplete solution for cartilage damage. BST-CarGel, a chitosan-based medical device, is mixed with autologous whole blood and is applied to a microfractured cartilage lesion in which it physically stabilizes the clot and guides and enhances marrow-derived repair. An international,(More)
The purpose of this study is to determine whether arthroscopic acromioplasty is equivalent or superior to open acromioplasty, in a prospective, randomized, controlled, blinded clinical trial. Seventy-one patients with a clinical diagnosis of impingement syndrome were randomized to arthroscopic or open acromioplasty. Nine were excluded because of(More)
PURPOSE We evaluated the hypothesis that circulating tumor cells as determined using the CellSearch System would correlate with tumor volume, pathological stage and Gleason score in men with localized prostate cancer. MATERIALS AND METHODS Samples of blood (30 ml) were drawn from 97 men with localized prostate cancer before radical prostatectomy, on(More)
OBJECTIVE The efficacy and safety of BST-CarGel®, a chitosan scaffold for cartilage repair was compared with microfracture alone at 1 year during a multicenter randomized controlled trial in the knee. This report was undertaken to investigate 5-year structural and clinical outcomes. DESIGN The international randomized controlled trial enrolled 80(More)
OBJECTIVE To report on all complications experienced by patients with displaced intra-articular calcaneal fractures (DIACFs) following nonoperative management or open reduction internal fixation (ORIF). DESIGN Prospective, randomized, multicenter study. SETTING Four level I trauma centers. PATIENTS The patient population consisted of consecutive(More)
