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)
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)
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)
Vascularization of engineered bone tissue is critical for ensuring its survival after implantation and it is the primary factor limiting its clinical use. A promising approach is to prevascularize bone grafts in vitro using endothelial progenitor cells (EPC) derived from peripheral blood. Typically, EPC are added together with mesenchymal stem cells (MSC)(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)
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)
OBJECTIVE To simulate anterosuperior instability of the shoulder by a combination of massive irreparable rotator cuff tears and coracoacromial arch disruption in cadaveric specimens, use proximally based conjoined tendon transfer for coracoacromial ligament (CAL) reconstruction to restrain against superior humeral subluxation, and investigate its(More)
OBJECTIVE To review the research progress in the repair and reconstruction of isolated traumatic radial head dislocation with annular ligament injury in children. METHODS In recent years, the related literature concerning isolated traumatic radial head dislocation with annular ligament injury in children was reviewed. RESULTS For isolated traumatic(More)
CSN5 has been implicated as a candidate oncogene in human cancers by genetic linkage with activation of the poor-prognosis, wound response gene expression signature. The present study aimed to investigate the effect of silencing CSN5 on invasion and cell cycle progression of human colorectal cancer cells, and to determine the potential molecular mechanisms(More)
OBJECTIVE To investigate the applications of fluoroscopy-based navigation in pelvic fractures and related surgical considerations. METHODS From May 2010 to December, 16 patients with pelvic fractures were treated with computerized navigation. There were 12 males and 4 females with an average age of 37 years (ranged from 20 to 54 years). Fractures were(More)
