BACKGROUND Although no prospective studies have compared functional results of trochanteric osteotomy and a non-trochanteric approach, most surgeons feel that trochanteric osteotomy is outdated in simple hip arthroplasty. Reasons not to perform an osteotomy include the fear of longer rehabilitation and worse (final) functional outcome. METHOD This prospective study examines differences in reh...

Osteoporosis has become a serious global public health issue. Hence, osteoporotic fracture healing has been investigated in several previous studies because there is still controversy over the effect osteoporosis has on the healing process. The current study aimed to analyze two different periods of bone healing in normal and osteopenic rats. Sixty, 7-week-old female Wistar rats were randomly d...

BACKGROUND Tarsal tunnel syndrome is a known complication of lateralizing calcaneal osteotomy. A Malerba Z-type osteotomy may preserve more tarsal tunnel volume (TTV) and decrease risk of neurovascular injury. We investigated 2 effects on the tarsal tunnel of the Malerba osteotomy compared to a standard lateralizing osteotomy using a cadaveric model: (1) the effect on TTV as measured by magneti...

Superior gluteal nerve emerges through the greater sciatic foramen above the piriformis muscle. The nerve curves upwards and forwards between the gluteus medius and minimus muscles, supplies both of them and ends by supplying the tensor fasciae latae muscle, from its deep surface. During hip surgeries, this nerve often gets injured resulting in complications. An exact knowledge of its course is...

INTRODUCTION Some authors have hypothesised that atypical femur fractures occur due to tensile mechanism of failure. We studied the distribution of such lesions along the femur shaft to determine if they concentrate in regions that are subject to tensile loading. METHODS From May 2004 to March 2010, radiological reviews of 48 patients aged 69 +/- 10.4 (range 47-92) years with atypical femoral...

BACKGROUND Rotational acetabular osteotomy (RAO), Chiari osteotomy and shelf procedure are important treatments to delay the progression of osteoarthritis in developmental dysplasia of hip (DDH) patients, but their biomechanical differences are still unknown. This study was to evaluate the different biomechanical changes of hip joint after these three surgeries. METHODS Sixteen DDH models of ...

Power force velocity profiles of ballistic push offs are increasingly more used for the purpose of performance assessment. The main input parameter for such profiles is jump height. This study aims to propose and validate a simple low cost method for calculating jump heights based on 2D tracking of the trochanter. Furthermore a comparison with the existing low cost time in air method was carrie...

Iliopsoas impingement is an uncommon cause of pain after total hip arthroplasty. If pain persists after a trial of conservative treatment, surgical intervention can alleviate the patient's symptoms. Multiple advantages exist to release the iliopsoas tendon at the level of the lesser trochanter. The purpose of this Technical Note is to demonstrate a technique for arthroscopic release of the ilio...

high tibia osteotomy is a common procedure in orthopedic surgery. a precise overview on indications, patients selection, pre-operative planning, surgical technique, methods of fixation, and complications have been presented. this paper focused on the points that should be considered to achieve good long-term outcomes. high tibia osteotomy is a common procedure in orthopedic surgery. a precise o...

A 65-year-old female had a history of tuberculosis of the left greater trochanter 30 years ago. She underwent 6 months of chemotherapy after which the disease healed completely. Currently she presented to us with pain and swelling on the lateral aspect of left hip of 2-month duration. Clinical and radiological findings were suggestive of a recurrence. Biopsy was conclusive for tuberculosis. She...
