Osteochondromas, or exostoses, are overwhelmingly found as isolated lesions although they can be present within the context of multiple hereditary exostosis. Increased exostotic load associated with multiple hereditary exostosis can lead to limb-length discrepancy, increased femoral anteversion, valgus angulation, and acetabular dysplasia. Solitary osteochondromas have been linked with bursal i...

PURPOSE This study aimed to investigate the outcomes of modular neck-utilization in primary total hip arthroplasty (THA). MATERIALS AND METHODS Thirty patients (34 hips) who had modular stem THA between April 2011 and January 2013 were evaluated. There were 19 men and 11 women with a mean age of 61.2 years at the time of surgery. There were 20 cases of osteonecrosis of femoral head, 7 cases o...

INTRODUCTION Medial rotation deformity of the hip is a problem to patients who are handicapped by cerebral palsy but able to walk, because the knees point inward during gait ("kissing patellae") and cause falls and frequent injuries. Knees and ankles are subject to stress and, therefore, they assume compensating positions. Lower legs assume position of valgus and external rotation, whereas feet...

BACKGROUND The clinical outcome of hip resurfacing (HR) as a demanding surgical technique associated with a substantial learning curve depends on the position of the femoral component. The aim of the study was to investigate the effects of the level of surgical experience on computer-assisted imageless navigation concerning precision of femoral component positioning, notching, and oversizing ra...

PURPOSE This study assessed the short term clinicoradiological results of primary total hip arthroplasty using third generation ceramic-ceramic articulation Accolade TMZF femoral stems. MATERIALS AND METHODS Two hundred and seventy two patients (294 hips) with primary total hip arthroplasty using third generation ceramic-ceramic articulation Accolade TMZF femoral stems who had been followed-u...

BACKGROUND Retrieval studies have suggested that the cause of femoral implant failure after metal-on-metal hip resurfacing is multifactorial. Both varus positioning of the femoral component and notching of the superior part of the femoral neck have been associated with femoral component failure. The hypotheses of this study were that placement of a femoral resurfacing component alters femoral n...

INTRODUCTION The hip fractures appear to be a real epidemic problem, especially in the western world, due primarily to higher average age. The social and economical impact is considerable with a continue social and health costs up-rising. The female-male ratio is approximately 8:1. PURPOSE The purpose of this report is to present a system of osteosynthesis for fractures of the lateral femoral...

Because there is no consensus with regard to the efficiency of the Frejka pillow in the treatment of hip joint dysplasia in newborns, the aim of the present study was to evaluate our results with this device. During the 3-year period 1988 to 1990, the Frejka pillow was used in 108 newborns with clinically unstable hips verified by ultrasonography. There were three treatment failures (2.8%), def...
