Vascularized Greater Trochanter Bone Flap Transfer for Treatment of ARCO Stage-IIB to IIIB Osteonecrosis of the Femoral Head

Indications for free vascularized fibular grafting for the treatment of osteonecrosis of the femoral head

BACKGROUND The present study aimed to determine the indications for free vascularized fibular grafting for the treatment of osteonecrosis of the femoral head. METHODS Seventy-one hips (60 patients) were clinically followed for a minimum of 3 years. Average follow-up period was 7 years. Etiologies were alcohol abuse in 31 hips, steroid use in 27, idiopathic in 7 and trauma in 6. Preoperative s...

Indications of Free Vascularized Fibular Grafting for the Treatment of Osteonecrosis of the Femoral Head

Available Findings Fail to Provide Strong Evidence of the Role of Bone Morphogenic Protein-2 in Femoral Head Osteonecrosis

Despite widespread research on non-traumatic femoral head osteonecrosis (FHON), there is no consensus about preventative treatment options. Insufficient blood supply and increased intra-osseous pressure are the initiating events in the majority of cases. BMPs are growth factors that belong to the transforming growth factor β (TGFβ) superfamily. Two specific formulations of BMPs have already bee...

Autologous Bone Marrow Mesenchymal Stem Cells Associated with Tantalum Rod Implantation and Vascularized Iliac Grafting for the Treatment of End-Stage Osteonecrosis of the Femoral Head

Tantalum rod implantation with vascularized iliac grafting has been reported to be an effective method for the treatment of young patients with osteonecrosis of the femoral head (ONFH) to avert the need for total hip arthroplasty (THA). However, there have been unsatisfactory success rates for end-stage ONFH. The authors describe a modified technique using bone marrow mesenchymal stem cells (BM...

Application of bone marrow mesenchymal stem cells to the treatment of osteonecrosis of the femoral head.

Osteonecrosis of the femoral head (ONFH) is a type of common and refractory disease in the orthopedic clinic that is primarily caused by a partial obstruction of the blood supply to the femoral head, resulting in a series of pathological processes. Mesenchymal stem cells (MSCs) comprise a mixture of various stem cells in myeloid tissue with multipotential differentiation capacity. They can diff...
