PURPOSE The external snapping hip syndrome is caused by slippage of the iliotibial band over the greater trochanter. Most cases are treated conservatively but if this fails, open surgical treatment is commonly performed by Z-plasty or by creating a defect on the iliotibial band. We present a series of 11 hips that were surgically treated by an endoscopic(More)
We reviewed a series of consecutive total hip replacements with cemented femoral components. Modern cementing techniques were followed in all cases, but two different medullary plugs were used—one was polyethylene and the other bioabsorbable gelatin. Cement mantle quality and plug migration were assessed by three different observers (X, Y, and Z); their(More)
Primary total hip replacement (THR) is performed by different approaches. The traditional transtrochanteric approach described by Charnley1 is not commonly used today in primary surgery and has been substituted for less invasive approaches.2 The posterior approach is popular in THR. Favored by many surgeons, it provides anatomic dissection and less(More)
Hip arthroscopy has become a standard surgical procedure. Specific portals and portal placement techniques are well described and routinely used. The anterior portal placement relies on the ability of the surgeon to introduce a needle into the joint from the landmark located at the crossing of a vertical line from the anterior superior iliac spine and a(More)
PURPOSE The purpose of this study was to examine the arthroscopic findings in the hips of patients with long-term follow-up of Chiari osteotomies. TYPE OF STUDY Prospective consecutive series of patients. METHODS Seven consecutive patients (1 male, 6 female; average age, 23 years) having a Chiari osteotomy performed in 1 hip during childhood or(More)
PURPOSE The internal snapping hip syndrome is caused by slippage of the iliopsoas tendon over the iliopectineal eminence or the femoral head. Open surgical techniques have been successfully used to treat this condition. More recently, endoscopic techniques have become available to address this problem. The purpose of this study was to investigate an(More)
