“…These authors would not, of course, be able to comment on asymptomatic patients with subluxation or those who were not symptomatic enough to warrant a referral; many of these patients might undergo THA at a later age or not at all. Others [59] suggest an ''inevitability of disabling coxarthrosis'' in patients with recognized subluxation. In our study cohort, 54% of all hips with preoperative subluxation (Severin Grade 4 and higher) did not have additional surgery at a mean age of 41 years with a mean Merle d'Aubigné score of 16 points.…”

The goal of the Bernese periacetabular osteotomy is to correct the deficient acetabular coverage in hips with developmental dysplasia to prevent secondary osteoarthrosis. We determined the 20-year survivorship of symptomatic patients treated with this procedure, determined the clinical and radiographic outcomes of the surviving hips, and identified factors predicting poor outcome. We retrospectively evaluated the first 63 patients (75 hips) who underwent periacetabular osteotomy at the institution where this technique was developed. The mean age of the patients at surgery was 29 years (range, 13-56 years), and preoperatively 24% presented with advanced grades of osteoarthritis. Four patients (five hips) were lost to followup and one patient (two hips) died. The remaining 58 patients (68 hips) were followed for a minimum of 19 years (mean, 20.4 years; range, 19-23 years) and 41 hips (60%) were preserved at last followup. The overall mean Merle d'Aubigné and Postel score decreased in comparison to the 10-year value and was similar to the preoperative score. We observed no major changes in any of the radiographic parameters during the 20-year postoperative period except the osteoarthritis score. We identified six factors predicting poor outcome: age at surgery, pre-

“…These deformities lead to abnormal stress distributions on the articular weightbearing area, elevated joint contact pressures, and shearing stresses on the acetabular rim complex [10,12,24]. Thus, these patients often have labral tearing and cartilage degeneration develop at an early age, resulting in premature hip osteoarthritis [18,26,30,37,38].…”

“…Early secondary osteoarthritis of the hip often develops in young adults who have a dysplastic acetabulum [1][2][3][4][5][6][7]. Wiberg described the development of osteoarthritic changes in young adults who had a dysplastic hip with <20° of the centre-edge (CE) angle on antero-posterior radiographs [6,7].…”

“…Plain radiographs allow a diagnosis of dysplasia to be made [1][2][3][4][5][6][7][8][9][23][24][25][26][27][28], however, these two-dimensional (2D) images lack three-dimensional (3D) information and accurate quantification of the degree and location is difficult.…”

Objective Little data exists on the original morphology of acetabular dysplasia obtained from patients without radiographic advanced osteoarthritic changes. The aim of this study was to investigate the distribution and degree of acetabular dysplasia in a large number of patients showing no advanced degenerative changes using three-dimensional computed tomography (3DCT). Materials and methodsEighty-four dysplastic hips in 55 consecutive patients were studied.All 84 hips were in pre-or early osteoarthritis without radiographic evidence of joint space narrowing, formation of osteophytes or cysts, or deformity of femoral heads. The mean age at the time of CT scan was 35 years (range 15-64 years). 3D images were reconstructed and analyzed using recent computer imaging software (INTAGE Realia and Volume Player).Deficiency types and degrees of acetabular dysplasia were precisely evaluated using these computer software.Results The average Harris hip score at CT scans was 82 points. Twenty-two hips (26%) were classified as anterior deficiency, 17 hips (20%) as posterior deficiency, and 45 hips (54%) as lateral deficiency. No significant difference was found in the Harris hip score among these groups. The analysis of various measurements indicated wide variations. There was a significant correlation between the Harris hip score and the acetabular coverage (p < 0.001). ConclusionOur results indicated wide variety of deficiency type and degree of acetabular dysplasia. Hips with greater acetabular coverage tended to have a higher Harris hip score.
