Acetabular redirection osteotomy can be used to relieve pain, improve function, and extend the life of dysplastic hip joints. To understand better the factors that may determine the acetabular reorientation that minimizes pressures, joint contact pressures were calculated by computer assisted methods in 70 dysplastic and 12 normal hips (82 patients). Calculated pressures were consistent with pr...

BACKGROUND A new minimally invasive transsartorial approach for the Bernese periacetabular osteotomy was developed. We investigated whether this technique was safe and successful with regard to minimizing tissue trauma and, more importantly, whether it was possible to obtain optimal reorientation of the acetabulum. METHODS Our experience with this approach was retrospectively assessed by mean...

BACKGROUND Preserving the hip joint to delay arthroplasty for patients with acetabular dysplasia-associated early-stage osteoarthritis has become more common, and several surgical procedures have demonstrated pain relief and improved hip joint function. Periacetabular osteotomy, one of the joint-preserving surgical procedures of the hip, provides favorable outcomes, although there are no report...

BACKGROUND AND PURPOSE Giant cell tumors (GCTs) of bone rarely affect the pelvis. We report on 20 cases that have been treated at our institution during the last 20 years. METHODS 20 patients with histologically benign GCT of the pelvis were included in this study. 9 tumors were primarily located in the iliosacral area, 6 in the acetabular area, and 5 in the ischiopubic area. 8 patients were ...

The objective of this study was to assess outcome and recurrence rate after limb-salvage surgery with reconstruction for pelvic bone tumors and analyze complications and their relationship with surgery. The authors analyzed 129 patients followed for a mean of 6 years (range, 2-19 years). Chondrosarcoma was the most frequent histotype. Thirty-one cases with no acetabular involvement were reconst...

Acetabular fractures are produced by high energy injuries that often cause dislocation of the fragments with gaps and steps (Olson et al., 1997). The goal of operative treatment of such fractures is to restore acetabular anatomy with perfect fragment reduction and stable fixation in order to enable early joint movement (Letournel and Judet, 1993). The fixation of the fragments is not strong eno...

Total hip replacement has evolved into one of the most frequently performed reconstructive procedures in orthopaedic surgery today. A modified anterior approach developed by the senior surgeon has been utilized in performing over 3,000 operations in the past two decades. It is a unique and facile exposure. It can be easily applied to primary and revision surgery. Noncemented prostheses have bee...

  Background: Anterior pelvic ring surgery includes a variety of plating techniques and insertion of retrograde superior pubic ramus screws. Anterior acetabular surgery also includes fixation through an ilioinguinal or Stoppa approach. These exposures risk injury to the spermatic cord and accompanying genital branch of the genitofemoral nerve. The primary aim of this study was to identify the d...

Introduction: Anthropometric studies provide valuable information in different populations. This study was conducted to evaluate the anatomical variations of the normal hip joint among Tehran population, Iran, in comparison with other populations. Methods: This study was carried out on hip joint of 260 patients in all ages and both genders referred to the Department of Radiology at Ebn-e Sina ...

Purpose Several studies have recently found an association between acetabular labral tears and the early onset of osteoarthritis. For this reason, treatment of labral tears in young and active patients is crucial for hip preservation. We retrospective reviewed 300 cases for hip acetabular labral tears that treated with hip arthroscopy surgery. The clinical results and image evaluation results w...
