PURPOSE We evaluated the results of more than 10 years of follow-up of total hip arthroplasty using a second-generation cementless femoral prosthesis with a collar and straight distal fixation channels. MATERIALS AND METHODS One hundred five patients (129 hips) who underwent surgery between 1991 and 1996 for primary total hip arthroplasty using cementless straight distal fluted femoral stems ...

The purpose of the present study was to compare the effects of alendronate and alfacalcidol on cancellous and cortical bone mass and bone mechanical properties in ovariectomized rats. Twenty-six female Sprague-Dawley rats, 7 months of age, were randomized by the stratified weight method into four groups: the sham-operated control (Sham) group and the three ovariectomy (OVX) groups, namely, OVX ...

BACKGROUND Accurate evaluation of the plain radiography of lower limb is critical for preoperative planning of total knee arthroplasty (TKA). We aimed to investigate the effect of femoral lateral bowing and rotation on the radiographic measurements of distal femoral condyle resection thickness (DRT) and the distal femoral resection valgus angle (FVA). METHODS We analyzed 246 three-dimensional...

BACKGROUND Progressive genu varum with disturbance of medial tibial physeal growth (classic Blount disease) is a well-studied phenomenon, and in rare cases, genu varum can occur because of medial distal femoral physeal growth disturbance (so-called femoral Blount disease). To our knowledge, progressive genu valgum caused by disturbance of lateral distal femoral physeal growth has not been descr...

Background. Intra-articular fractures of distal femur present a huge surgical challenge. The aim of this study is to evaluate functional outcome, fracture healing, and the complications of distal femoral intra-articular fractures using locking compression plates. Material and Methods. We reviewed 46 distal femoral fractures treated with distal femoral locking compression plates between 2009 to ...

BACKGROUND Distal femur fractures are difficult to manage, and the selection of implant approach for internal fixation remains controversial. This study explores the clinical outcome of treating distal femoral fractures with a locking compression plate using a posteriolateral novel approach. METHODS Twenty patients with distal femoral fractures were included in our study, and all patients und...

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...

The aim of this study was to evaluate the results of minimally invasive percutaneous plate osteosynthesis (MIPPO) of distal femoral fractures in elderly diabetic patients with osteoporotic bone. Thirteen supracondylar or intercondylar femoral fractures were treated by MIPPO with a locked plate without bone grafting. All fractures healed, with only one delayed union in a patient who had deep inf...

BACKGROUND Medial patellofemoral ligament (MPFL) reconstruction in adults often utilizes screw fixation in the distal femur. The aim was to define the safety of similar fixation in young patients, with respect to their open physis. PURPOSE To define the age-related relationship between the femoral insertion of the MPFL and the medial aspect of the distal femoral physis on magnetic resonance i...

In the setting of periprosthetic joint infection, the complete removal of implants and cement can be challenging with well-fixed, cemented implants about the knee. This can get especially complex in the setting of long cemented femoral component stems. Osteotomies are well described in the proximal femur and tibia for removal of implants and cement. There is little information available on dist...
