We report a case of spontaneous physeal growth arrest of the distal femur in a nine-year-old child with Ewing's sarcoma of the proximal femur treated with chemotherapy and endoprosthetic replacement. Owing to the extent of disuse osteoporosis at the time of surgery, the entire intramedullary canal up to the distal femoral physis was filled with cement. Three years later, the femur remained at i...

BACKGROUND Tumors of the distal femur and diaphysis with proximal metaphyseal extension into the femur present a challenge for limb salvage. The conventional treatment consists of limb salvage with total femur replacement. This case study aims to present preliminary results and experience with short-stem reconstruction, focusing on the mechanical stability of the procedure. METHODS Sixteen sh...

The article presents the case of a patient who after her first pregnacy, during the immediate postpartum period, suffered a femoral supracondylar fracture complicated by bone marrow edema syndrome (BMES), also known as regional temporary osteoporosis (RTO). The fracture of the distal femur was treated with an open reduction and internal fixation of the distal femur by means of a minimally invas...

A previous study showed that 1 mm of distal femoral resection restored knee extension 4.5°. We determined the relationship with a more accurate measurement technique. Twenty-six subjects treated with total knee arthroplasty were studied. Digital photographs of the extended knee with and without 1.5 and 3.0 mm thick augments placed between the femoral component and distal femur were analyzed, an...

BACKGROUND The configuration of the distal surface of the femur would be more important in terms of the patellofemoral (PF) joint contact because the patella generally contacts with the distal surface of the femur in knee flexion. Some total knee arthroplasty (TKA) designs configurate medially prominent asymmetric femoral condyles. This difference in the design of distal femoral condyle may aff...

Background: Osteoporosis is the most common metabolic disease of the bone in the world, and has hit about 200 million people around the world and it increases the risk of fractures. More than 5 million osteoporotic fractures occur annually in the world. Bone mineral density is the standard method of diagnosis of this disease. In this method, proximal of femur (neck) and lumbar vertebra bones (L...

We describe a minimally invasive procedure for removal of a distal femur locking plate using arthroscopic assistance. Using lateral accessory portals, we performed arthroscopically-assisted removal of distal locking screws. Under fluoroscopic image, proximal screws were removed from the diaphysis. The accessory lateral portal sites used to remove the distal screws were connected. Through this a...
