We have studied whether the state of the articular cartilage at the time of rotational acetabular osteotomy for dysplasia of the hip affects the outcome 2 to 5.5 years after surgery. Arthroscopy in 57 patients (59 joints) at the time of the operation showed grade-0 changes in seven, grade-1 in nine, grade-2 in 17, grade-3 in 14 and grade-4 in 12 joints, according to the classification of Outerb...

We used a large prospective institutional registry to determine if there is a 'safe zone' that exists for acetabular component position within which the risk of hip dislocation is low and if other patient and implant factors affect the risk of hip dislocation. Patients who reported a dislocation event within six months after hip arthroplasty surgery were identified, and acetabular component pos...

BACKGROUND We analyzed the extent of the comminution in the acetabular weight-bearing area, the clinical and radiographic results, and the complications after a minimum 2-year follow-up of the modified Stoppa approach for the treatment of acetabular fractures, and we attempted to evaluate the efficacy of the operative technique. METHODS All of the 22 patients, who needed the anterior approach...

Lewinnek et al described a safe zone of acetabular component placement in Total Hip Arthroplasty (THA) to reduce complications. This safe zone is between 10-30 degrees of version and 30-50 degrees of inclination 1 . Callanan et al. reports only 53% of acetabular cups were within Lewinnek’s Safe Zone of optimal cup placement (62% within the abduction safe zone, 79% within the version safe zone)....

BACKGROUND Patients with symptomatic femoroacetabular impingement (FAI) frequently have bilateral deformity and inquire about the prognosis of their contralateral, asymptomatic hip. Idiopathic coxarthrosis has been established as an independent risk factor for joint failure on the other side. PURPOSE To determine the prevalence of bilateral arthroscopic treatment for FAI and to identify predi...

We report the outcome of 161 of 257 surgically fixed acetabular fractures. The operations were undertaken between 1989 and 1998 and the patients were followed for a minimum of ten years. Anthropometric data, fracture pattern, time to surgery, associated injuries, surgical approach, complications and outcome were recorded. Modified Merle D'Aubigné score and Matta radiological scoring systems wer...

We report the clinical and radiological outcome at ten years of 104 primary total hip replacements (100 patients) using the Metasul metal-on-metal bearing. Of these, 52 had a cemented Stuehmer-Weber polyethylene acetabular component with a Metasul bearing and 52 had an uncemented Allofit acetabular component with a Metasul liner. A total of 15 patients (16 hips) died before their follow-up at t...

Acetabular fractures are quite challenging injuries for the orthopedic surgeon due to low incidence and the deep and complex anatomy. A 61 y old man fell from a single-storey house and sustained a right acetabular fracture and cartilage wear. The dual-column was fixed with cannulated screw fixation via anterior ilioinguinal approach and received second surgery of open reduction and pelvic recon...

We carried out a clinical and radiological review of 103 cementless primary hip arthroplasties with a tapered rectangular grit-blasted titanium press-fit femoral component and a threaded conical titanium acetabular component at a mean follow-up of 14.4 years (10.2 to 17.1). The mean Harris hip score at the last follow-up was 89.2 (32 to 100). No early loosening and no fracture of the implant we...

The increasing need for total hip replacement (THR) in an ageing population will inevitably generate a larger number of revision procedures. The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. The failed acetabular component requires reconstruction to restore the hip centre and improve joint biomechanics. Impaction bone ...
