Background: Evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. Although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative CT scanning. The purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational ...

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 Correction of a distal femoral deformity may prevent or delay the onset of osteoarthritis or mitigate its effects. Accurate correction of deformity without production of a secondary deformity depends on precise localization and quantification of the deformity. We report a technique to correct distal femoral deformities in the coronal plane. METHODS Fourteen femora in thirteen skele...

background: massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. the purpose of this study was to analyze the outcome of these procedures at imam reza hospital, mashhad university of medical sciences. methods: in this study, 113 cases have been presented. eleven cases were excluded (patients has a traumatic...

OBJECTIVE To evaluate the medium-term outcome of limb-salvage surgery using all-polyethylene tibial endoprosthetic replacement following en-block resection for distal femoral tumors. METHODS Forty-nine patients with distal femoral tumor were treated between June 2006 and June 2012. The follow-up period was 6-110 months (average 53.4 months). The prosthetic survival was analyzed using the Kapl...

Introduction: The indications for intramedullary nail fixation of fractures of the femoral shaft have been greatly expanded by techniques of interlocking nailing. However, distal locking screw fixation remains the most technically demanding and problematic portion of the procedure and maybe responsible for as much as one-half of the exposure of the surgeon’s hands to radiation during the proced...

Introduction . Computer modeling and additive technologies are increasingly used in medicine. Oncoorthopedics is no exception. Careful preoperative planning the creation of individual instruments make it possible to perform radical operations, which allows maximum preservation healthy tissues leads an increase functional potential patients postoperative period. Objective – improve results surgi...

A computer-aided 3-dimensional (3D) visualization operation simulation system based on computer-aided design (CAD) Unigraphics NX and Mimics software was established to provide orthopedic surgeons with an actual and reliable system in treating of distal femoral fracture.According to the preoperative CT data, 3D reconstruction of the distal femoral fracture could be achieved by the Mimics softwa...
