PURPOSE To review medium-term outcomes of 46 patients who underwent total hip replacement (THR) for osteoarthritis secondary to dysplastic hips. METHODS Records of 58 hips in 6 men and 40 women aged 32 to 76 (mean, 62) years who underwent THR for osteoarthritis secondary to dysplastic hips and had been followed up for a mean of 4 (range, 2-8) years were retrospectively reviewed. The hips were...

PURPOSE OF THE STUDY The aim of this study is to assess the mid-term results specific ultra-short, cementless stem in patients younger than 60 years with regard clinical and radiographic outcomes, survivorship, complication rate revisions. MATERIAL AND METHODS A consecutive series one hundred twenty-one (130 hips) at time surgery was enrolled study. Primary arthritis (33.8%) dysplastic hips (30...

In a longitudinal case-control study, we followed 81 subjects with dysplasia of the hip and 136 control subjects without dysplasia for ten years assessing radiological evidence of degeneration of the hip at admission and follow-up. There were no cases of subluxation in the group with dysplasia. Neither subjects with dysplasia nor controls had radiological signs of ongoing degenerative disease a...

We studied the reproducibility of ultrasonographic screening examination of the hip when read by diagnostic radiographers. In order to determine interobserver variability, 200 ultrasonograms were classified according to Graf's method by five observers (four radiographers and one radiologist). The kappa values for interobserver variability indicated moderate agreement (kappa 0.47) for the exact ...

Background. Residual dysplasia occurs in some hip joints with DDH treated conservatively. This may lead to osteoarthrosis in relatively near future. Our study aimed to determine which radiographic parameters and clinical factors could reliably predict hip joint development after closed reduction. Material and methods. We examined 81 patients and 107 hip joints treated with over-head traction. T...

The results obtained in a consecutive series of thirty-seven Pemberton operations for congenital dislocation or subluxation of the hip are reported. Over the period under review, 1967 to 1973, it was the only type of acetabuloplasty employed at Winford. Unless the mandatory concentric reduction could be obtained with ease, preliminary open reduction was favoured, especially in cases of primary ...

OBJECTIVE To evaluate acetabular morphology and the prevalence of dysplasia in a Saudi population, and compare it with others in different geographical areas. METHODS The study took place at King Fahd University Hospital, Al-Khobar, Kingdom of Saudi Arabia from May 2005 to April 2006. We recruited radiographs of 104 patients of 40-88 years of age. We digitally measured the center edge angle (...

Although some navigation systems have been used for improvement of component positioning, there have been few reports regarding cases of severe pelvic deformity. We performed a retrospective review of 25 cases of total hip arthroplasty with a computed tomography-based navigation system in patients with severe pelvic deformities and estimated acetabular component position and angle between sever...

Using radiography and computer tomography (CT) we studied the morphology of 83 hips in 69 Caucasian adults with osteoarthritis secondary to developmental dysplasia of the hip (DDH). A previously published series of 310 hips with primary osteoarthritis was used as a control group. According to the Crowe classification, 33 of the dysplastic hips were graded as class I, 27 as class II and 23 as cl...

BACKGROUND Hip arthroscopy is recognized as a highly effective means of treating joint disorders. Complications in hip arthroscopy, including neurovascular traction injury, compression injury to the perineum and scope trauma, have been reported. We report our experience with 73 hip arthroscopy procedures and complications at Chang Gung Memorial Hospital. METHODS Seventy-two patients with 73 h...
