BACKGROUND Prognosis of traumatic osteonecrosis of femoral head in children is poor for either conservative treatment or surgical intervention. Intravenous bisphosphonate is an expecting medication to reduce femoral head resorption and to prevent femoral head collapse after traumatic osteonecrosis. This mechanism will reduce development of osteoarthritis and disability in the future. OBJECTIV...

Hip resurfacing (HR) is a highly attractive option for young and active patients. Some surgeons have advocated cementing the metaphyseal stem of the femoral component to improve fixation and survivorship of HR. However, extending component fixation to the metaphysis may promote femoral head strain shielding, which in turn may reduce survival of the femoral component. Replacing the metallic meta...

PURPOSE To compare the efficacy of quadratus femoris muscle pedicle bone flap transplantation combined with hollow compression screw fixation versus AO hollow compression screw fixation in the treatment of femoral neck fracture for Chinese young and middle-aged patients. METHODS Case-controlled studies (CCTs) were used to compare the two operative methods in the treatment of femoral neck frac...

Background The purpose of this meta-analysis was to compare the outcomes of external fixation and flexible intramedullary nails for femoral fractures in children between 5 and 15 years of age based on the current evidence. Materials and methods We searched relevent studies in the following database: Cochrane library, PubMed and EMABASE up to May 2014. All randomized controlled trials, Clinica...

PURPOSE Fixation of proximal femoral megaprostheses is achieved in the diaphyseal isthmus. We hypothesized that after extended bone resection including the proximal part of the isthmus a reduced length of fixation will affect the stability and fixation characteristics of these megaprostheses. The aim of this study was to analyze in a validated sawbone model with extended proximal femoral defect...

Cementless femoral fixation by means of bone ingrowth has been successful in total hip arthroplasty in patients with sufficient bone quality. Consistent bone ingrowth and resultant long-term success involve many factors, including surgical technique, initial mechanical stability achieved at time of implantation, stem design and material, and implant surface. One potential method for achieving f...

OBJECTIVE To determine the initial resistance of fixation using the Rigid Fix(®) system, and compare it with traditional fixation methods using metal interference screws; and to evaluate the resistance of the fixation with the rigid fix system when the rotational position of the bone block is altered in the interior of the femoral tunnel. METHODS forty ovine knee specimens (stifle joints) wer...

BACKGROUND AND PURPOSE There is very little information on the cost of different treatments for femoral neck fractures. We assessed whether total hospital and societal costs of treatment of elderly patients with displaced femoral neck fractures differ between patients operated with internal fixation or hemiarthroplasty. METHODS 222 patients (mean age 83 years, 165 women (74%)) who had been ra...

BACKGROUND Intracapsular femoral neck fractures are associated with high rates of nonunion. We aimed to identify risk factors for nonunion in patients with both displaced and nondisplaced intracapsular femoral neck fractures treated with three 7-mm parallel cannulated screws, placed in either a triangle or an inverted triangle configuration, using failure of fixation as the primary outcome. M...

The use of pin fixation for grafts in the femoral tunnel in anterior cruciate ligament (ACL) reconstruction is becoming more popular. The transtibial stiff femoral guides are necessary to ensure that the pins fix the graft. However, the cross pins can sometimes miss the femoral tunnel. As a result of some technical problems that we encountered, we introduced an extra step in the technique of th...
