Abstract
OBJECTIVES Despite the success rate of the Pavlik method in the treatment of developmental dislocation of the hip, there is a subset of hips that do not reduce with harness use. The purpose of this study was to determine the outcomes after closed reduction (CR), open reduction (OR) and combined open reduction and pelvic osteotomy (OR+PO) in patients with infantile hip dislocations who initially failed the Pavlik method. METHODS This was a retrospective cohort study of patients with infantile hip dislocations who failed the Pavlik method and subsequently underwent a secondary procedure for persistent hip dislocation. The primary outcome measure was the Severin classification of the involved hip 3 years after the secondary procedure. Other outcomes assessed included rates of redislocation, residual acetabular dysplasia and proximal femoral growth disturbance. RESULTS Twenty-three patients were included; seven subsequently underwent CR, three underwent isolated OR and 13 proceeded directly to OR+PO. The overall successful outcome rate at final follow-up (as determined by radiographic Severin class I or II) was 11/23 (48%). However, patients undergoing OR+PO had significantly higher rates of successful outcomes (77%) compared with CR (15%) and OR (0%), P < 0.05. The rate of residual acetabular dysplasia and proximal femoral growth disturbance was significantly lower in patients treated with OR+PO compared with CR and isolated OR, P < 0.05. CONCLUSION Patients with dislocated hips who failed Pavlik harness treatment had better radiographic outcomes 3 years after OR+PO in comparison to patients undergoing CR or isolated OR.

Abstract
Objective This study aimed to determine the short- and medium-term outcomes of hip dislocation in infants who failed Pavlik harness therapy and were subsequently treated with brace, closed reduction (CR) or open reduction (OR) before 6 months of age. Methods Fifty infants (66 hip dislocations) who failed Pavlik harness therapy between 2000 and 2018 and were treated with a rigid abduction brace or undergoing a CR or OR/cast were evaluated. All demographic data obtained from the medical system, developments and complications during the follow-up and treatment process were recorded and evaluated. Results Fifty infants (66 hips) with dislocated hips failed Pavlik harness therapy. Of these, 9 infants (12 hips) underwent rigid abduction splint therapy: 9 hips were successful, 2 hips had CR and 1 had OR. Thirty-eight infants (51 hips) had index CR, of which 3 (3 hips) failed and had OR. Radiographs of 49 hips (44 patients) were normal at the final evaluation. Pavlik harness therapy starting after 3 weeks (P = 0.028) and unilateral dislocations (P = 0.028) increased the risk of needing operating room. There was an association between OR and avascular necrosis (P = 0.025), but not between OR and other complications-dysplasia and re-dislocation/subluxation (P = 0.257 and P = 0.508, respectively). Conclusion Closed treatment of hip dislocation is possible in most babies who fail Pavlik treatment. Babies who are started on Pavlik therapy after 3 weeks of age may be at increased risk of needing an operating room. Level of Evidence IV.

Abstract
The objective of this study was to analyze a multicenter cohort of children with developmental dysplasia of the hip (DDH) who underwent treatment with closed reduction. We sought to report the effects that severity of hip dysplasia and age have on the development of femoral head avascular necrosis (AVN) and the need for additional procedures. All patients with DDH and minimum 2 years of follow-up who underwent closed reduction were identified. The following variables were recorded: sex, laterality of hip involvement, age, acetabular index (AI), and International Hip Dysplasia Institute (IHDI) grade. The effects of patient age and pre-procedure IHDI grade on the rate of AVN and need for additional procedures after the closed reduction were analyzed using an alpha of 0.05. Seventy-eight total hips were included in the final analysis. The average patient age was 12 months. AVN of the femoral head was reported in 24 hips (30.8%) and 32 hips (41.0%) required additional surgery. Higher pre-op IHDI grade was associated with higher risk of developing Bucholz-Ogden grades II-IV AVN of the femoral head ( P = 0.025) and requiring additional surgery ( P = 0.033) regardless of patient age. There were no statistically significant differences for the effect of age on the measured outcomes ( P > 0.05). These findings suggest that severity of dislocation (IHDI grade) is a significant risk factor for the development of AVN and need for additional procedure.

Abstract
INTRODUCTION The current published evidence for the treatment of developmental dysplasia of the hip (DDH) with failed closed reduction (CR) following failed Pavlik harness (PH) treatment is still limited. This study aimed to determine whether an one-stage open reduction (OR) would lead to a similar outcome to a two-stage OR in these patients. Meanwhile, the occurrence of femoral head avascular necrosis (AVN) and further surgery (pelvic osteotomy, PO) within the follow-up period was investigated. MATERIALS AND METHODS A consecutive series of DDH patients who failed CR following failed PH treatment and received OR finally between January 2008 and December 2020 were studied. The patients were divided into two groups. One group of which received OR immediately after failed CR (one-stage OR group, Group A), and the other received a delayed OR (two-stage OR group, Group B). The McKay's criteria, acetabular index (AI) and the degree of dislocation of the hips were evaluated for the final outcomes. RESULTS At the last follow-up, 54 (84.4%) of the 64 hips in Group A and 26 (83.9%) of 31 hips in Group B were in excellent or good condition. Comparison between the two groups revealed that there were no differences in terms of McKay grading (P = 0.950), AI (P = 0.783), incidence of AVN (P = 0.745), and also incidence of PO (P = 1.000). However, a significant lower mean AI was found in Group A, when the OR was performed in Group B (31.06 ± 4.45° vs. 33.87 ± 4.12°, P = 0.004). CONCLUSION Both of the one- and two-stage OR may acheive favorable outcomes. Moreover, one-stage OR is of without the general anesthesia risk associated with two-stage OR. We therefore advocate that an OR should be performed in appropriate DDH patients during the same session once a failed CR is detected.

Abstract
Aims Abduction bracing is commonly used to treat developmental dysplasia of the hip (DDH) following closed reduction and spica casting, with little evidence to support or refute this practice. The purpose of this study was to determine the efficacy of abduction bracing after closed reduction in improving acetabular index (AI) and reducing secondary surgery for residual hip dysplasia. Methods We performed a retrospective review of patients treated with closed reduction for DDH at a single tertiary referral centre. Demographic data were obtained including severity of dislocation based on the International Hip Dysplasia Institute (IHDI) classification, age at reduction, and casting duration. Patients were prescribed no abduction bracing, part-time, or full-time wear post-reduction and casting. AI measurements were obtained immediately upon cast removal and from two- and four-year follow-up radiographs. Results A total of 243 hips underwent closed reduction and 82% (199/243) were treated with abduction bracing. There was no difference between those treated with or without bracing with regard to sex, age at reduction, severity of dislocation, spica duration, or immediate post-casting AI (all p > 0.05). There was no difference in hips treated with or without abduction brace with regard to AI at two years post-reduction (32.4° (SD 5.3°) vs 30.9° (SD 4.6°), respectively; p = 0.099) or at four years post-reduction (26.4° (SD 5.2°) vs 25.4° (SD 5.1°), respectively; p = 0.231). Multivariate analysis revealed only IHDI grade predicted AI at two years post-reduction (p = 0.004). There was no difference in overall rate of secondary surgery for residual dysplasia between hips treated with or without bracing (32% vs 39%, respectively; p = 0.372). However, there was an increased risk of early secondary surgery (< two years post-reduction) in the non-braced group (11.4% vs 2.5%; p = 0.019). Conclusion Abduction bracing following closed reduction for DDH treatment is not associated with decreased residual dysplasia at two or four years post-reduction but may reduce rates of early secondary surgery. A prospective study is indicated to provide more definitive recommendations.

Abstract
BACKGROUND The current study aims to investigate the clinical efficacy of closed reduction and cast immobilization for patients with developmental dysplasia of the hip (DDH) who failed Pavlik harness treatment. METHODS Patients with DDH who underwent cast immobilization under general anaesthesia after the failure of the Pavlik harness or Tübingen brace treatment between January 2015 and December 2020 were retrospectively recruited. General information, including Graf classification of initial diagnosis, initial treatment, age of cast immobilization, IHDI classification, AI index, avascular necrosis (AVN), and residual dysplasia, was collected. The incidence of AVN and late acetabular dysplasia (LACD) was also estimated. Moreover, factors related to AVN and LACD were investigated by multiple logistic regression analysis. RESULTS Thirty-four patients (47 hips) were finally included in the current study. Of these patients, 31 hips (66.0%) were successfully treated with closed reduction and cast immobilization. Open reduction was successfully performed in 16 hips (34.0%). Till the latest follow-up, LACD and AVN were found in 13 (27.7%) and 10 (21.3%) hips, respectively. In the open reduction group, type III and IV of the IHDI classification and type IV of the Ultrasound Graf classification were significantly higher when compared with the closed reduction group. Multiple logistic regression showed that failure of closed reduction was related to the initial types of the Ultrasound Graf and IHDI classifications. CONCLUSIONS Although the success rate of closed reduction after early harness failure in DDH is only 66%, we still advocate closed reduction as a first-line treatment for children who have failed sling treatment. Even if closed reduction fails, open reduction can still achieve acceptable results.

Abstract
PURPOSE To investigate the impact of failed Pavlik harness (PH) treatment on the outcomes following closed reduction (CR) or open reduction (OR) in developmental dysplasia of the hip (DDH). METHODS Ninety-three DDH patients treated with CR or OR were enrolled. One group of which received previous PH treatment (F group) and the other (L group) not. The clinical outcomes were evaluated according to McKay's criteria. Radiographs were evaluated for acetabular index (AI) and the degree of dislocation of the hips. RESULTS A higher rate of CR was found in F group (P = 0.034). Before CR/OR, the mean AI in F group was significantly lower than that in L group (P = 0.000), while at the last follow-up, the AIs in both groups were all improved. In F group, there were 7 (16.67%), 18 (42.86%) and 17 (40.48%) hips were classified as Graf type II, III and IV pathologic changes, respectively, when PH treatment started, while the corresponding data were 17 (40.48%), 17 (40.48%) and 8 (19.05%) after PH treatment (P = 0.024). At the last follow-up, no significant difference was found concerning the complications between the two groups (P > 0.05). CONCLUSIONS PH treatment, even if failed, may have the ability of accelerating the development of the acetabulum and increasing the rate of successful CR. Thus we advocate a trial of PH treatment for all DDH patients less than 6 months of age. Meanwhile, a close monitoring by dynamic ultrasonography is required due to the risk of AVN.
