Apophyseal fracture affecting the greater trochanter is a rare injury in children. We report a case of non traumatic avulsion of the greater trochanter in a 13-year-old boy who presented with a history of pain about his right hip over the past few months. Hip radiographs, radioisotope bone scan and CT scan confirmed the diagnosis of avulsion of the greater trochanter with minimal displacement. ...

The apophyseal fracture or avulsion of the greater trochanter occurs in skeletally immature patients. It has at etiological factors indirect mechanisms (avulsion) and direct mechanisms (trauma on the trochanter), the latter being the most common. The clinical presentation is easily identified and a simple X- ray can confirm the diagnosis. Regardless of the treatment chosen, this pathology has a...

A method of performing a biplanar intracapsular trochanteric osteotomy with a Gigli saw was designed and tested prospectively in 431 cases of Charnley low friction arthroplasty. Three methods of trochanteric reattachment were tested, and a double cross-over wire with a compression spring was best; this method was successful in 222 out of 226 patients (98.2%), of which half were revision operati...

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...

Introduction: Osteosynthesis of the femur using an interlocking nail is the gold standard for treating diaphyseal fractures of the femur. There are two established entry points for the antegrade interlocking nails which is the piriformis fossa or the greater trochanter. It has been reported that varus malalignment was frequently seen in proximal femur fracture which were treated with interlocki...

BACKGROUND The wire fixation and the cable grip fixation have been developed for the extended trochanteric osteotomy (ETO) in the revision of total hip arthroplasty (THA). Many studies reported the postoperative performance of the patients, but with little quantitative biomechanical comparison of the two fixation systems. METHODS An in-vitro testing approach was designed to record the looseni...

The extra-articular impingement of the greater trochanter against the ileum is an underrated cause of early dislocation in total hip arthroplasty. In this preliminary study, the authors assess the effectiveness of an anterior longitudinal osteotomy of the greater trochanter for preventing dislocation. A total of 115 patients underwent a total hip arthroplasty through a posterolateral approach. ...

In his model of the biomechanics of the proximal human femur, Friedrich Pauwels assumes a resultant force acting on the femoral head that is created by the partial body weight and the force of the abductor muscles inserting at the greater trochanter. This model suggests a tensile force in the region of the greater trochanter. An exact examination of the muscle insertions at the greater trochant...

The clinical details of eight patients who have been treated for tuberculosis ofthe greater trochanter during the last 15 years are presented. Their average age was 56 years. In every case the diagnosis was not made for some time, partly because of the vagueness of the symptoms and partly because the surgeon seemed unaware that tuberculosis could occur at this site. In treatment it is recommend...
