femoral bone graft
Many methods are available including allograft autograft and synthetic bone grafts. Currently there are three distinct approaches by which the bone graft is introduced into the femoral head.

16 raised as a corticoperiosteal flap the graft can be rotated to the metaphyseal-diaphyseal area of the distal femur and.

Introduction and Radiographs JN is a morbidly obese 38-year-old African-American male who presented with a 2-year history of chronic left hip pain. Curettage and bone grafting with or without internal fixation 1 5.
From April 1989 to February 1996 6 primary and 18 revision TKAs with femoral bone grafting were performed in 22 patients with an average age of 62 years. Review of the literature has shown technical errors to be a major cause of ACL reconstruction failures with various studies reporting rates of 24 to 64. The purpose of this study was to evaluate the clinical and radiographic results of TKAs with morsellized and solid femoral bone grafting.
We describe the clinical outcomes of the surgical treatment of benign lesions of the proximal femur including the femoral neck using a compression hip screw and synthetic bone graft. Structural grafting for femoral reconstruction has been used in femoral revision surgery in connection with partial bone loss. Furthermore such grafting preserves the natural hip geometry and articular cartilage unlike the osteot-.
Bone Grafting Bone grafting helps repair bones after a severe fracture or when they do not heal correctly. It has been freeze dried sterilized with gamma irradiation and has an approximate weight of 20g. We performed an in vitro experiment to evaluate the use of high hydrostatic pressure HHP.
13-18 Specifically femoral tunnel malposition has been implicated as the primary cause of failure in 60 to 79 of patients. Strut bone grafts such as fibular bone grafts provide not only graft material but also provide structural support to the head of the femur to prevent collapse. 1 a core tract entering from the lateral and proximal femur.
There are several treatment options for benign bone tumors of the proximal femur. Grafting also fuses two adjoining bones to treat chronic pain. Multiple allograft and autograft options exist as do the techniques used to perform grafting of ACL femoral or tibial tunnel defects.

Femoral Head OsteonecrosisProximal Femoral Osteotomy and Open Bone Grafting Procedures Harpal P. 1719-22 We hypothesize that MARS surgeons will also identify femoral tunnel malposition at the time of. Bone graft obtained from a cadaver and inserted after processing Most commonly used bone substitute Properties osteoconductive only due to lack of viable cells the degree of osteoconduction available depends on the processing method fresh frozen or freeze-dried and type of graft cortical or cancellous.
These graft choices include autologous reamer-irrigator-aspirator RIA harvested bone from the femur 7 8 autologous iliac crest or proximal tibia bone graft cores 9 allograft bone dowels 10 11 and synthetic dowels. Eleven knees were affected by rheumatoid. The total volume of the bone graft was significantly higher for Group 3 78 29 ml compared to Group 1 29 11 ml and Group 2 30 11.
Donated from deceased tissue donors. Vascularized fibular grafts additionally provide nutrients to the bone graft and are hypothesized to replace the necrotic bone with new bone through creeping substitution. We describe a simple method to treat large bone defects of the femoral shaft combined with heterotopic bone formation after treatment for femoral shaft fractures with large bone loss using the heterotopic bone as bone graft material.
Drumm Samik Banerjee Patient Case. The medial femoral condyle bone graft is based on the descending geniculate artery which arises from the superficial femoral artery and richly vascularizes the periosteum and cortical bone of the medial femoral condyle. 2 a window in the femoral neck the so called lightbulb procedure or 3 an elevated trapdoor through the femoral head articular cartilage5 Historically nonvascularized bone grafting introduced.
This method will be especially useful for cases that have both long bone defects of the femoral shaft and ectopic bone formation as well as. Cortical strut grafting of the femur during revision total hip arthroplasty tha can help reconstruct bone defects and restore bone stock eliminate stress risers which might cause later fracture provide stable fixation of periprosthetic fractures and can reduce pain from mechanical mismatch of the bone and implant at the tip of some femoral. The current standard for sterilization of potentially infected bone graft by gamma irradiation and thermal or chemical inactivation potentially deteriorates the biomechanical properties of the graft.
Which is widely used as a disinfection process in the food. The femoral head has been processed to remove soft tissue cut in half longitudinally and washed to deplete cell and marrow content. Bone grafting is an attractive treatment option in that it combines the benefit of decompressing the femoral head with the added benefit of introducing an osteoconductive andor osteoinductive material into the devitalized head.
