PURPOSE To identify and quantify the presence of extra-articular tibia vara that might influence the mechanical axis alignment after total knee arthroplasty (TKA). MATERIALS AND METHODS A total of 48 TKAs in 30 osteoarthritic Indian patients were prospectively evaluated. The hip-knee-ankle angle (HKA), joint line convergence angle, and varus angulation at the femur and tibia were measured fro...

This study examined the axial and torsional stiffness of polyaxial locked plating techniques compared with fixed-angle locked plating techniques in a distal tibia pilon fracture model. The effect of using a polyaxial screw to cross the fracture site was examined to determine its ability to control relative fracture site motion. A laboratory experiment was performed to investigate the biomechani...

VOL. 75-B, No. 2, MARCH 1993 (Fig. 1). The usual below-knee amputation would have left too short a stump. We therefore decided to amputate the bone, 6 cm below the knee, and turn up a section of the healthy distal tibia on a long posterior flap to lengthen the stump. We excised the middle two-thirds of the tibia, with the anterior and lateral compartments, and disarticulated the foot at the ank...

BACKGROUND Measurement of bone mineral density by dual x-ray absorptiometry combined with clinical risk factors is currently the gold standard in diagnosing osteoporosis. Advanced imaging has shown that older patients with fragility fractures have poor bone microarchitecture, often independent of low bone mineral density. We hypothesized that premenopausal women with a fracture of the distal en...

PURPOSE. To report on 23 patients with giant cell tumour (GCT) of the femur or tibia treated with curettage, electrocautery, burring, phenol irrigation, and cementation. METHODS. Records of these 14 men and 9 women aged 22 to 38 (mean, 31) years were reviewed. The most common site involved was the distal femur (n=13), followed by proximal tibia (n=8), proximal femur (n=1), and distal tibia (n=1...

BACKGROUND This randomized, parallel-group, non-blinded study was designed to determine the role of fibular fixation in the treatment outcomes of combined distal tibia and fibula fractures. MATERIALS AND METHODS Sixty patients with distal tibial and fibular fractures were randomly divided in two groups of case and controls. In the case group, fibula was fixed prior to the fixation of tibia. I...

OBJECTIVES To define pQCT precision errors, least-significant-changes, and identify associated factors for bone outcomes at the radius and tibia in children. METHODS We obtained duplicate radius and tibia pQCT scans from 35 children (8-14yrs). We report root-mean-squared coefficient of variation (CV%RMS) and 95% limits-of-agreement to characterize repeatability across scan quality and least-s...

In a study of 23 intra-articular fractures of the distal tibia of which 18 were re-examined after an average follow-up period of 5.4 years, two major fracture patterns were identified: type A, a rotational pattern, caused by low energy trauma and type B, a compressive fracture pattern caused by high energy trauma. Type B fractures could be divided into three subgroups: 1) An isolated fracture o...
