Current indications for trochanteric osteotomy include improving exposure to the femoral intramedullary canal through correction of proximal femoral angular deformities, such as medial greater trochanteric overhang1; improving general exposure to the acetabulum and femoral canal in complex primary and revision hip total hip arthroplasty (THA)2; and facilitating exposure to the anterosuperior ac...

Fracture of the femoral prosthesis neck following total hip arthroplasty is not common. We report a case of femoral prosthesis neck fracture in an adult male patient following modular, uncemented total hip arthroplasty. This case report further emphasizes the importance of the potentially high loading situation in the prosthetic femoral neck. On the other hand, the occurrence of a femoral prost...

Femoral osteotomy is performed for osteonecrosis of the femoral head to prevent progression collapse and promote repair process by transposing necrotic lesion nonweight-bearing portion. The purpose this review article was summarize current knowledge on two types osteotomy: transtrochanteric anterior or posterior rotational curved varus osteotomy, both which are currently osteonecrosis, mainly i...

Periprosthetic femoral fracture post-total knee arthroplasty can lead to malunion. This may lead to abnormal force transmission and accelerated wear of the prosthesis. Accurate femoral deformity correction depends on the combined correction of the mechanical axis alignment and the lateral distal femoral angle. Modern external fixation correction devices allow for simultaneous gradual correction...

BACKGROUND Subtrochanteric oblique osteotomy (SOO) has been widely used to reconstruct highly dislocated hips in uncemented total hip arthroplasty. The occurrence of complications can be attributed to the instability of the osteotomy region. The aim of this study was to evaluate the initial stability of SOO in uncemented total hip arthroplasty. MATERIAL AND METHODS A 3-dimensional finite elem...

BACKGROUND The purpose of this study was to investigate periosteal vessels location as intra-operative landmarks in distal femoral osteotomies and focused on the branching pattern of the vascular supply of the medial and lateral femoral condyle, its constancy, and the relationship to the height of distal femoral osteotomies. Anastomoses of relevant vessels were studied to analyze the risk of va...

BACKGROUND Numerous proposed surgical techniques have had minimal success in managing greater trochanter overgrowth secondary to retarded growth of the femoral capital epiphysis. For reconstruction of residual hip deformities, a novel type of proximal femur L-osteotomy was performed with satisfactory results. Although the clinical outcome was good, the biomechanical characteristics of the femur...

BACKGROUND Late-onset tibia vara (Blount disease) can be difficult to treat because of frequent morbid obesity and associated deformities, including distal femoral varus, proximal tibial procurvatum, and distal tibial valgus, that contribute to lower extremity malalignment. We present a comprehensive approach that addresses all components of the deformity and allows restoration of the anatomic ...
