Femoral torsion has been implicated in the pathogenesis of patellar luxation and cranial cruciate ligament disease (CCLD). However, obtaining an objective and reproducible measurement of this conformation remains a challenge, thereby preventing accurate surgical correction. The purpose of this presentation is to review the traditional methods for assessing femoral torsion, discuss their limitat...

The use of modular implants in femoral stem design has grown increasingly popular over the last decade because of the theoretical advantage of more flexibility and optimization of femoral anteversion, limb length, and femoral component offset. With the benefit of increased surgical flexibility, however, modularity also carries the theoretical risks of fretting at the modular surfaces, sequelae ...

OBJECTIVE To evaluate the validity of physical examinations by assessment of correlation between physical examinations and CT measurements in children with intoeing gait and the causes of intoeing gait by age using CT measurements. METHOD Twenty-six children with intoeing gait participated in this study. The internal and external hip rotation, thigh-foot angle and transmalleolar angle were me...

An abnormality of femoral anteversion (FA) is often recognized in patients with osteoarthritis of the hip joint (hip OA). And it is considered that rotation abnormality in the knee and the lower leg occurs as compensation, in cases of FA abnormality. The purpose of this study was to assess the magnitude and variability of FA and femoral condyle rotation (FCR) in order to identify the associatio...

BACKGROUND Excessive femoral anteversion is common in cerebral palsy (CP), is often associated with internal hip rotation during gait, and is frequently treated with a femoral derotational osteotomy (FDO). Concerns exist regarding long-term maintenance of surgical outcomes. Past studies report varying rates of recurrence, but none have employed a control group. METHODS We conducted a retrospe...

BACKGROUND Hip prostheses with short anatomical stems were designed for metaphyseal fixation and to spare bone stock. We present a study of a short anatomical femoral stem used in all age groups of patients with Dorr A and B type of femora. METHODS We reviewed radiographs of 85 hips in 74 patients who had a cementless total hip arthroplasty with a short anatomical 80 mm femoral stem designed ...

In 1937 Blount described a series of 28 patients with 'Tibia vara'. Since then, a number of deformities in the tibia and the femur have been described in association with this condition. We analysed 14 children with Blount's disease who were entered into a cross-sectional study. Their mean age was 10 (2 to 18). They underwent a clinical assessment of the rotational profile of their legs and a C...

Primary hip arthroplasty is a surgical procedure through which the coxofemoral joint is replaced with a prosthetic implant. Arthroplasties can be total or partial, cemented or uncemented. These procedures are generally indicated as a form of treatment for arthritic pain or in the case of severe trauma, such as femoral neck fractures. The most commonly used approaches are: Smith Peterson, Watson...
