BACKGROUND Anterior cervical discectomy and fusion is a standard treatment for symptomatic cervical disc disease, but pseudarthrosis and accelerated adjacent-level disc degeneration may develop. Cervical disc arthroplasty was developed to preserve the kinematics of the functional spinal unit. Trials comparing arthroplasty with anterior cervical discectomy(More)
HYPOTHESIS Clavicular fractures account for 2% to 2.6% of all fractures. Plating has been considered the gold standard for treating midshaft clavicular fracture. Intramedullary pinning and conservative treatments have also been commonly used. We hypothesized that intramedullary pinning and conservative treatments have the same treatment results compared(More)
PURPOSE To evaluate the curative effect of Ilizarov bone transport combined with antibiotic cement spacer for infected tibial nonunion with bone defect. METHODS We retrospectively reviewed the outcomes of 58 patients with infected tibial nonunion from January 2008 to March 2011 at our institution. Patients were treated with complete debridement, radical(More)
BACKGROUND We evaluate the clinical results of reconstructing massive juxta-articular defects of the distal femur (mean, 16.4 cm) with series-connected double-strut free-vascularized fibular grafting (FVFG) and external fixator fixation. METHODS We retrospectively reviewed a consecutive series of 19 patients, who underwent FVFG transfer because of massive(More)
The objective of this meta-analysis was to compare the fixation outcome of the Gamma nail and dynamic hip screw (DHS) in treating peritrochanteric fractures. Relevant randomised controlled studies were included, and the search strategy followed the requirements of the Cochrane Library Handbook. Methodological quality was assessed and data were extracted(More)
The limited repair potential of articular cartilage, which hardly heals after injury or debilitating osteoarthritis, is a clinical challenge. The aim of this work was to develop a novel type I collagen (Col)/glycosaminoglycan (GAGs)-porous titanium biphasic scaffold (CGT) and verify its ability to repair osteochondral defects in an animal model with bone(More)
BACKGROUND Subtrochanteric fractures of the femur complicated with segmental bone defects are uncommon injuries and challenging to manage. We evaluated the effect of reconstructing extensive bone defect in the subtrochanteric area (mean, 6.9 cm) with folded free vascularized fibular graft (FVFG). METHODS Between 2001 and 2007, 14 cases of subtrochanteric(More)
A 40-year-old woman had her right extremity avulsed at the proximal upper arm level and the wrist and hand of her left extremity irretrievably injured in a traffic accident. The right distal forearm was surgically amputated and replanted onto the stump of the left distal forearm. New strategy for nerve repair was applied and the function recovery of the(More)
OBJECTIVES Total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) are treatment choices for end-stage shoulder osteoarthritis. The decision of whether to use TSA or HA is controversial. The objective of this study was to compare the effects of TSA and HA for shoulder osteoarthritis. METHODS We conducted a search for clinical studies that had been(More)
Due to their good biocompatibility and mechanical integrity, tissue engineering scaffolds have become a principal method of repair and regeneration of osteochondral defects. To improve their intrinsic properties, control their degenerative times, and enhance their cell adhesion and differentiation, numerous scaffold architectures and formation methods have(More)
