Implant design and positioning are important factors in maintaining stability and minimizing dislocation after total hip arthroplasty. Although the advent of modular femoral stems and acetabular implants increased the number of head, neck, and liner designs, the features of recent designs can cause intra-articular prosthetic impingement within the arc of motion required for normal daily activit...

Objective: To study the variations in anthropometric parameters of adult human femora including total length, shaft angle anteversion and neck femur Pakistani origin. Study Design: Descriptive Correlational. Setting: Department Anatomy, Rawalpindi Medical University. Period: April, 2022 to June, 2022. Material & Methods: Eighty undetermined gender age were selected from bone bank Anatomy De...

OBJECTIVE To assess the intra-rater and inter-rater reliability for measuring femoral anteversion angle (FAA) by a radiographic method using three-dimensional computed tomography reconstruction (3D-CT). METHODS The study included 82 children who presented with intoeing gait. 3D-CT data taken between 2006 and 2014 were retrospectively reviewed. FAA was measured by 3D-CT. FAA is defined as the ...

Introduction: Osteochondroplasty of the anterior head-neck junction is often performed to treat femoro-acetabular impingement (FAI) on the assumption that the underlying deformity is inadequate anterior offset of the femoral head. However, other morphologic abnormalities, including reduced anteversion, posterior slip, and widening of the neck can all cause loss of joint motion. In this study we...

PURPOSE Past classification for the treatment of idiopathic genu vara depended simply on the measurement of distance between the knees, without attention to the rotational profile of the lower extremity. We retrospectively analyzed anatomical causes of idiopathic genu vara. PATIENTS AND METHODS Twenty eight patients with idiopathic genu vara were included in this study. All patients were surg...

Background: A novel modification of an existing technique was developed to allow precise fluoroscopic assessment of rotational alignment of the fractured femur during intramedullary nailing. It is hypothesized that this will reduce the incidence of rotational malalignment which is reported to occur in 20-30 % of femoral fractures managed with intramedullary nails. The neck lateral technique has...
