BACKGROUND This study is aimed at evaluating the operation techniques and clinical significance of free flap transplantation combined with skin grafting and vacuum sealing drainage (VSD) in repairing severe traumatic extensive circumferential or semi-circumferential soft-tissue defects of the lower leg. MATERIAL AND METHODS Thirty patients with severe(More)
PURPOSE The aim of the study is to evaluate the surgical technique and clinical significance of the sequential therapy of vacuum sealing drainage (VSD) and free-flap transplantation for children with extensive soft-tissue defects below the knee in the extremities. METHODS Twenty-two children (aged from 3 to 10 years) received sequential therapy of VSD and(More)
BACKGROUND Physiological loading is widely believed to be beneficial in maintaining skeletal integrity by stimulating new bone formation through increases in osteoblastic activity and concomitant decreases in osteoclastic activity. However, excessive or nonphysiological loading is associated with bone injuries, including stress fractures and osteoporotic(More)
OBJECTIVE To explore the surgical technique and clinical value of treatment for posttraumatic large circular soft tissue defect in the lower extremities using a combination of posterior tibial vascular bridge flap in the unaffected leg and skin graft covered by vacuum sealing drainage (VSD). METHODS From January 2008 to June 2010, 11 cases with(More)
OBJECTIVE To investigate the feasibility of inducing in vitro mesenchymal stem cells (MSCs) derived from adult human bone marrow differentiate into osteoblasts and potential applicability of the MSCs as the seed cells in tissue engineering. METHODS Adult human bone marrow was collected from the healthy adult volunteers to obtain the MSCs, which, after in(More)
OBJECTIVE To explore new techniques for the treatment of comminuted distal femoral fractures to promote functional restoration and reduce the complications of the fracture. METHODS Sixteen adult canines were selected for this study, and the experimental and control hindlimb for each canine were randomly determined. Distal comminuted fracture (AO/ASIF Type(More)
Intra-abdominal migration of Kirschner wire is unusual in children. We present a case of intra-abdominal migration of Kirschner wire used for stabilization of the hip joint during pelvic osteotomy, and its successful removal under digital subtraction angiography.
OBJECTIVE To discuss the experience with three-dimensional reconstruction technique in initial clinical application in gastrocnemius muscle flap surgery. METHOD From 2007 to 2008, 7 patients received gastrocnemius muscle flap surgeries to repair the wounds. Preoperative CT angiography or magnetic resonance imaging (MRI) was performed after injection of(More)
SUMMARY Since arthroplasty, prosthetic replacement and non-vascularised articulation autografting do not normally produce very satisfactory results for ankylosis of metacarpophalangeal and interphalangeal joints, the authors performed reconstruction of phalangeal articulations of the hand using vascularised phalangeal articulations of the foot in 11(More)
OBJECTIVE To describe the surgical techniques and our experiences in fingertip replantation after amputation. METHODS On the basis of examination of the anatomic features and the degree of fingertip vascular injury, 32 amputated fingertips in 26 cases were replanted, and flexible revascularization procedures of both artery and vein anastomoses,(More)
