We report a rare complication during primary total knee arthroplasty. An intramedullary femoral guide rod was broken during insertion. The broken part jammed into the isthmus of the femur. An initial attempt to push the broken rod via the proximal femur by a guide wire to the distal femur was unsuccessful because the broken rod was lodged in the isthmus. Ultimately, the isthmus was opened using...
Osteoarthrosis (OA) is a multi-factorial disease characterized by the progressive loss of articular cartilage and the development subchondral sclerosis, intra-osseous cysts and osteophytes. In addition to changes in cartilage which occur in OA, it is suggested that early changes are seen in the adjoining subchondral and trabecular bone (1). In this work we develop, optimize and extend MR techni...
The increasing problems in the field of osteoporotic fracture fixation results in specialized implants as well as new operation methods, for example, implant augmentation with bone cement. The aim of this study was to determine the biomechanical impact of augmentation in the treatment of osteoporotic distal femur fractures.Seven pairs of osteoporotic fresh frozen distal femora were randomly ass...
Epidermal cells from different circumferential positions around the femur of Blabera craniifer can interact to form an intercalary regenerate. Removal of a longitudinal strip of integument (cuticle plus epidermis) from any position around the circumference leads to the cut edges healing, localized growth and intercalary regeneration of the missing section of the circumference, so that the resul...
Malignant transformation of conventional giant cell tumor of bone is rare and usually occurs with irradiation. This article describes a case of malignant transformation of a giant cell tumor 15 years after initial curettage and bone graft. A 35-year-old man was admitted to the hospital with a recurrent giant cell tumor of the distal femur. On presentation, the patient reported the insidious ons...
Background: Proper rotation of components in total knee arthroplasty (TKA) will largely affect the postoperative outcome. Ethnical variation may affect rotational profile. We aimed to evaluate distal femur rotation in Iranian population using transepicondylar axes. Methods : From a total of 450 knee CT scans and via consecutive sampling, 150 qualified subjects with normal lower extremities ...
The present study investigated the case of a 46-year-old female with primary malignant perivascular epithelioid cell neoplasm (PEComa) of the femur. The patient presented with a 5-month history of right distal thigh pain following trauma. Radiographs of the right distal femur revealed a mixed lytic and sclerotic lesion with subtle areas of cortical destruction and soft tissue extension, consist...
