“…Murphy et al [15] reported the acetabular index of depth-to-width in patients with hips that did not develop severe arthritis by the age of 65 had a mean value of 48%, whereas dysplastic acetabula in which secondary osteoarthritis was more likely to develop had an average depth-towidth ratio of 31%. In our series, the mean acetabular depth-to-width ratio, the Reimers index, and the centeredge angle in the younger age group was 42.1%, 0.16, and 30.5°, respectively.…”

The Pembersal operation combines features of the Pemberton and Salter osteotomies. Results have usually been reported in patients with dysplasia but without frank dislocation. We asked if the following factors influence the outcome of the Pembersal operation in patients with dislocated hips: triradiate cartilage damage causing early closure; the acetabular index improvement; and the age of the patient at time of operation. We assessed triradiate cartilage damage, a modified McKay clinical classification, acetabular index, center-edge angles, Reimers index, acetabular depth-to-width ratios, Severin classification and Tönnis grading of 33 patients (44 hips) have been evaluated in this retrospective study. The mean age at surgery was 5 years (range, 1.5-14 years). The minimum followup was 5 years (mean, 10.5 years; range, 5-17 years). Preoperatively, three (7%) hips were Tönnis Grade 2, 10 (23%) were Grade 3, and 31 (70%) were Grade 4. Eight (18%) hips were Severin Class 1, 32 (73%) Class 2, and four (9%) were Class 3. According to McKay's criteria satisfactory results with a rate of 76% were obtained.

“…This report lacked a control group and also did not describe progression of degenerative change over time [10]. A natural history of the skeletally mature dysplastic hip has been reported by Murphy and colleagues [15]. This study retrospectively evaluated 286 young patients who had undergone THA for dysplasia, placing focus on the contralateral nonoperative hip.…”

“…These patients also had statistically greater derangement of all seven evaluated radiographic features of dysplasia. This investigation lacked a control group and did not describe progression of osteoarthritis over time; furthermore, a substantial portion of patients had signs of mild osteoarthritis at the time of inclusion [15]. Thus, an important current deficit in our knowledge is documentation of degenerative change over time in a cohort representing the spectrum of hip morphologies with no signs of osteoarthritis at study initiation and similar prognostic risk.…”

“…Acetabular coverage is best measured on radiographs, lateral coverage on the AP radiograph using the acetabular index as well as the center-edge angle of Wiberg, and anterior coverage using the ventral center-edge angle on the false profile view of Lequesne [26] (ie, 65°internal rotation) [2,7,30,34,51]. Values less than 15°are associated with considerable dysplasia or subluxation and often suggest the need for operative intervention.…”

Although the use of ultrasound in the diagnosis and early treatment of developmental dysplasia of the hip (DDH) has reduced the number of patients diagnosed late and decreased the number of operative procedures, surgical treatment is still needed in some patients. Late cases continue to occur as a result of missing the screening examination, being normal at initial screening and missing followup. Dysplasia may persist despite appropriate nonoperative or operative treatment. Many of these patients subsequently undergo closed or open reduction and femoral or acetabular reconstruction. Ultrasound of the hips is generally used up to 6 or 8 months of age, during which time the hips are largely cartilaginous, and radiographs after that time when bony development is more complete. Options to supplement ultrasound and radiography include arthrography, computed tomography, and magnetic resonance imaging. Several advances have been made in the imaging of DDH and its complications including acetabular labral pathology and of femoroacetabular impingement (FAI). We review imaging techniques other than ultrasound used in the management of DDH.
