Mid- and long-term outcome of Salter’s, Pemberton’s and Dega’s osteotomy for treatment of developmental dysplasia of the hip: a systematic review and meta-analysis

Abstract

Introduction: Early diagnosis and early treatment have become the gold standard for management of developmental dysplasia of the hip. Surgery is required in case of failed initial treatment. Innominate pelvic osteotomy of Salter (SIO), Pemberton’s pericapsular osteotomy (PPO) and Dega’s acetabuloplasty (DA) are among the most used procedures. We performed a systematic review and meta-analysis of the past 57 years in order to assess the mid- and long-term outcome of these techniques. Methods: Studies met inclusion criteria if they: (1) reported at least 5 cases treated by 1 of the abovementioned surgical techniques; (2) included children aged between 1 and 8 years; (3) surgical indication was late detected DDH or a failed initial treatment; (4) presented a minimal follow-up of 24 months; (5) reported the radiological score of Severin and/or the clinical score of McKay. Clinical and radiological outcomes were dichotomised into favourable and unfavourable outcome and weighted summary rates were determined using meta-analysis models. Results: From a total of 7391 articles, 48 level of evidence grade IV articles were included in our review. A total of 2143 cases with a mean follow up of 112.4 months were included. Pooled Severin score indicated a statistically better outcome for PPO and DA compared to SIO ( p = 0.0003 and p = 0.002, respectively). By dichotomising the results in favourable and unfavourable outcome, PPO showed the best results ( p = 0.0002 vs. SIO, p = 0.01 vs. DA). Pooled McKay score showed a statistically better outcome for PPO and DA compared to SIO ( p < 0.0001 and p = 0.03, respectively) as well as better outcomes for PPO compared to DA ( p = 0.01). By dichotomising the results in favourable and unfavourable, PPO showed the best results. Conclusions: Even if our review demonstrates slightly better radiological and clinical results with the PPO, the currently available and limited data do not allow for clear recommendation towards one of these techniques.

Clinicoradiological outcomes following pembersal acetabular osteotomy for developmental dysplasia of hip in young children: A series of 16 cases followed minimum 2 years

“…The radiological congruity as per Severin score reported with Salter, Pemberton and Dega osteotomy is 84%, 91.2% and 84% respectively. 15 For our series with Pembersal osteotomy, it was 87.5%. Thus, the Pembersal osteotomy appears to be at par or superior to above acetabular osteotomies in quantitative terms of restoring acetabular dysplasia and congruity.…”

“…14 Severin class I and II are considered favorable whereas classes III, IV, V and VI are considered unfavourable. 15 The avascular necrosis of hip (AVN) was documented by Kalamchi and MacEwen's classification. 16…”

Smith c/b ratio and teardrop figure measurements; Can it be used in the follow-up of patients who underwent salter innominate osteotomy?

“…[12,24–28] In addition, results were obtained to support the current evidence revealing that the Tönnis stage had no effect on success in patients undergoing surgical treatment. [1,8,12,23]…”

Salter vs Pemberton: Comparative Radiologic Analysis of Changes in the Acetabulum and Pelvis After Surgical Correction in Children with Hip Dysplasia

“…Научные публикации свидетельствуют о высокой эффективности данных методик хирур-гического лечения в среднесрочном и отдаленном периодах наблюдения [21,22,23,24]. Вместе с тем исследования, посвященные сравнительному анализу изменения рентгеноанатомического состояния тазобедренного сустава после остеотомии таза по Salter и Pemberton, носят единичный характер, несмотря на их широкое повсеместное применение [25,26,27,28]. Так, B. Dello Russo и J.G.…”
