The hip joint is commonly affected in juvenile chronic arthritis (JCA) and involvement is usually bilateral. It is well established that the involvement of the hip in JCA is the most important reason that the patient will lose independence and mobility. The positive gains, both in terms of hip function and the overall functional capability, of the patients(More)
BACKGROUND Intramedullary jigs are most often used for distal femoral bone cuts in total knee arthroplasty (TKA). However, the accuracy of bone cuts in the distal femur may be affected by the presence of diaphyseal deformities of the femur. METHODS Sixty-three patients (88 knees) with lateral bowing of the femur underwent primary TKA using a lateralized(More)
BACKGROUND Earlier literature on fixation of distal third humeral fractures describes the use of elaborate modification of existing implants, custom-made implants and dual plating. These modifications have the disadvantages of limitations of hardware availability and cost as well as longer surgical exposure to accommodate the plates. The aim of this study(More)
BACKGROUND Nonunion of diaphyseal fractures of the humerus are frequently seen in clinical practice (incidence of up to 15% in certain studies) and osteosynthesis using dynamic compression plates, intra medullary nails and Ilizarov fixators have been reported previously. Locking compression plates (LCP) are useful in the presence of disuse osteoporosis,(More)
PURPOSE The aim of this prospective study is the analysis of the clinical and radiological outcomes of active thoraco-lumbar spinal tuberculosis treated with isolated posterior instrumentation without any posterior bone grafting or anterior inter-body bone grafting or anterior instrumentation. METHODS The study was a prospective follow-up of 25 patients(More)
BACKGROUND The sliding screw-plate devices and cephalo-medullary nail devices have performed well in stable inter-trochanteric fractures in patients with reasonably good quality of bone. However, their suboptimal performance in comminuted fractures in the presence of osteoporotic bone has prompted many surgeons to consider bipolar hemiarthroplasty as the(More)
Mobile-bearing total knee arthroplasty designs were thought to be associated with lesser stresses on the polyethylene (PE) insert as compared to fixed-bearing designs. The wear rate of the PE liner was felt to be less in the mobile-bearing knees due to the decrease in the stresses. However, a reevaluation of the biomechanics of the mobile-bearing design is(More)
The current methods of dealing with research misconduct involve detection and rectification after the incident has already occurred. This method of monitoring scientific integrity exerts considerable negative effects on the concerned persons and is also wasteful of time and resources. Time has arrived for research administrators to focus seriously on(More)
STUDY DESIGN Prospective cohort study. PURPOSE To evaluate the contribution of upper and lower lumbar segments to flexion and extension of the lumbar spine in normal and diseased spines. OVERVIEW OF LITERATURE The specific contributions of upper and lower lumbar segments during flexion/extension have rarely been reported. Furthermore, no comparisons(More)
