INTRODUCTION Total knee prostheses with a mobile-bearing insert were developed to provide nonconstrained joint range of motion while reducing friction forces. The purpose of this study was, based on weightbearing X-rays, to evaluate the mobility of the polyethylene tibial insert in relation to the femoral and tibial components. We studied the results of a cementless total knee arthroplasty (TKA...

We reviewed 28 patients treated with partial fibulectomy combined with an Ilizarov compression frame for a non-infected tibial delayed union or non-union. Patient data, time to referral, type of fracture (open or closed), type of non-union (atrophic or hypertrophic) and period of treatment were recorded. Neither time to referral, type of fracture or type of non-union did adversely affect the du...

BACKGROUND Meniscus extrusion or hypertrophy may occur in knee osteoarthritis (OA). However, currently no data are available on the position and size of the meniscus in asymptomatic men and women with normal meniscus integrity. METHODS Three-dimensional coronal DESSwe MRIs were used to segment and quantitatively measure the size and position of the medial and lateral menisci, and their correl...

objective(s) the objective of this study was to document and explain bilateral differences in the q angle. materials and methods two hundred limbs of healthy adult indian volunteers were studied. the q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. the relative lateral placement of the tibial tuberosity with respec...

Background: The purpose of this study was to introduce a technical tip for the preparation of tibial tunnel in a posteriorcruciate ligament (PCL) reconstruction to reduce the chance of popliteal artery injury and duration of the surgery.Methods: This study included 18 patients who underwent PCL reconstructions at Imam Khomeini University Hospital,Tehran, Iran, between 2016 and...

We report a radiological sign which predicts progression to hypertrophic non-union for fractures of the tibial diaphysis. Radiographs of 46 tibial fractures were reviewed independently by four orthopaedic trauma surgeons and two musculoskeletal radiologists. Patients were identified from a database of tibial fractures managed with Ilizarov frame fixation. There were 23 fractures that progressed...

The purpose of the present study was to determine whether tactile cutaneous reflexes from the skin of the foot contain location-specific information during human walking. Muscular responses to non-nociceptive electrical stimulation of the sural, posterior tibial, and superficial peroneal nerves, each supplying a different skin area of the foot, were studied in both legs during walking on a trea...

BACKGROUND Severely disabled children with cerebral palsy (CP) are prone to low trauma fractures, which are associated with reduced bone mineral density. AIMS To determine whether participation in 50% longer periods of standing (in either upright or semi-prone standing frames) would lead to an increase in the vertebral and proximal tibial volumetric trabecular bone mineral density (vTBMD) of ...

Objective(s) The objective of this study was to document and explain bilateral differences in the Q angle. Materials and Methods Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with res...

The aims of this study were to define age-related histological changes in the articular cartilage of the stifle joint in non-chondrodystrophic dogs and to determine whether physical activity has a positive impact on preservation of cartilage structure during ageing. Twenty-eight German shepherd dogs were included in the study. These dogs had no evidence of joint inflammation as defined by clini...
