Abstract

UNLABELLED: 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. Premature closure of the triradiate cartilage occurred in eight (18%) hips and postoperative avascular necrosis of the femoral head in three (6%) hips. Satisfactory clinical and radiographic improvements in the aforementioned parameters can be obtained by Pembersal osteotomy.

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 33 participants or records.
