ABSTRACT Objective: To retrospectively evaluate the preliminary postoperative results of modified Dega-type acetabular osteotomy to treat developmental dysplasia of the hip, confirming the efficacy and reproducibility of this technique. Methods: This retrospective study included patients older than 18 months. A total of 19 hips underwent modified Dega osteotomy. Results: Satisfactory results were obtained, with an average decrease of the acetabular index from 39.2 to 20.6 degrees. The final average center edge angle was 29.6 degrees. Hip joint congruence was reestablished in all cases, and as of this writing, only one case developed necrosis in the femoral head during follow-up. Conclusion: Modified Dega osteotomy demonstrated good initial results, as well as the potential for use in treating developmental dysplasia of the hip. Level of Evidence IV; Case series.

Introduction Bilateral developmental dysplasia of the hip is a challenging situation, closed and open reduction with or without pelvic and femoral osteotomies are all proposed. Methods We investigated the feasibility of closed ilizarov reduction combined with Salter and femoral osteotomy to provide stable concentric hips. Results We retrospectively reviewed 19 patients (38 hips). Tonnis Criteria, acetabular index and Center-edge angle were measured preoperatively and postoperatively. Acetabular index changed significantly (P<0,001), 80% were excellent or good according to Mckay, 25% were Ia and 69% were IIa Severin's criteria with at least three years follow-up. Conclusion The midterm overall results are favorable for application of this technique.

Abstract The purpose of this systematic review is to assess outcomes and complications of patients undergoing Salter’s innominate osteotomies (SIOs) for the correction of hip dysplasia along with patient and technical factors that can be optimized to improve outcomes after SIO. MEDLINE and EMBASE were searched from data inception to 9 October 2018. Data were presented descriptively. Twenty-seven studies were identified including 1818 hips (87.1%) treated with SIO (mean age of 2.1 ± 2.5 years and mean follow-up of 3.5 ± 5.0 years). Patients undergoing SIO had a post-operative center-edge angle (CEA) of 31.3° ± 5.3° and an acetabular index (AI) angle of 16.1° ± 5.2°. Patients undergoing SIO with pre-operative traction had significantly lower (P = 0.049) post-operative McKay criteria scores compared to patients without pre-operative traction. Patients undergoing SIO between the ages of 1.5–2 years had significantly better (P &lt; 0.05) post-operative McKay criteria scores compared to patients aged 4–6 years. The complication rate was 9.4% with avascular necrosis (2.5%) being most common. This review found that SIO for developmental dysplasia of the hip produces generally good post-operative clinical outcomes. The CEA and AI can be corrected to normal range after SIO. Patients may have superior outcomes if they have SIO at a younger age, were not treated with pre-operative traction and did not have untreated contralateral hip dysplasia. Outcomes appear to be similar between one-stage bilateral SIO and a two-stage procedure in the setting of bilateral hip dysplasia; however, more multicentered studies are needed to confirm these results.

Purpose The purpose of this study was to evaluate the effect of correction of abnormal radiographic parameters on postoperative pain in a group of patients treated arthroscopically for femoracetabular impingement (FAI). Methods A retrospective study was performed on 23 patients affected by mixed-type FAI and treated arthroscopically. There were 11 males and 12 females with a mean age of 46.5 (range: 28–67) years. Center-edge (CE) and α angles were measured on preoperative and postoperative radiographic and magnetic resonance imaging (MRI) studies and were correlated with persistent pain at follow-up. Results The mean preoperative CE and α angles were 38.6 ± 5.2 and 67.3 ± 7.2 degrees, respectively. At follow-up, in the 17 pain-free patients, the mean pre- and postoperative CE angle were 38.1 ± 5.6 and 32.6 ± 4.8 degrees, respectively, whereas the mean pre- and postoperative α angles at MRI were 66.3 ± 7.9 and 47.9 ± 8.9 degrees, respectively. In six patients with persistent hip pain, the mean pre- and postoperative CE angles were 39.8 ± 3.6 and 35.8 ± 3.1 degrees, respectively, whereas the mean pre- and postoperative α angles were 70.0 ± 3.9 and 58.8 ± 2.6 degrees, respectively. Mean values of all the analyzed radiological parameters, except CE angle in patients with pain, improved significantly after surgery. On comparing patient groups, significantly lower postoperative α angles and lower CE angle were observed in patients without pain. Conclusion In case of persistent pain after arthroscopic treatment of FAI, a new set of imaging studies must be performed because pain may be related to an insufficient correction of preoperative radiographic abnormalities. Level of Evidence Level IV, retrospective case series.

Background and objectives: Closed reduction and short leg spica casting are the preferred treatment options for children with developmental dysplasia of the hip. This study aimed to show the efficacy behind a standardized closed reduction for managing patients with developmental dysplasia of the hip with concomitant soft tissue releases when indicated and using a short leg plaster of Paris cast to maintain reduction and reporting mid-term results. Methods: A case series of 95 hips in 84 children aged 6-18 months who had closed reduction, with five years follow up or until next operation, involved in this study. The protocol defines acceptable concentric reduction criteria and the indications for an associated soft tissue release. All the patients were immobilized in a short leg cast for three months. Multiple follow-up radiographs were taken to assess Tönnis grade, Severin grade, acetabular index, and osteonecrosis signs. Results: A total of 48 hips were Tönnis grade 3/4 hips. At one year, 15 reductions couldn’t be maintained, and these patients needed open reduction. Of these 15 failed reductions, 7 patients were Severin 1; others were Severin 2. Of the 80 successful closed reductions, 70 hips were Severin 1. Surgical management for residual dysplasia was offered for 8 hips. Osteonecrosis was seen in 23 hips but was transient in 20. Bilateral hip dislocations and most Tönnis 4 hips were more likely to fail. Two children had severe osteonecrosis. Conclusions: Closed reduction, with subsequent adductor and psoas releases, when indicated and using a short leg plaster of Paris cast for three months, brings about good mid-term results in children with developmental dysplasia of the hip aged 6-18 months. Keywords: Developmental dysplasia of the hip, closed hip reduction, open psoas release, short leg cast.

Purpose To describe patient-reported outcomes, radiological results, and revision to total hip replacement in patients with hip dysplasia that underwent periacetabular osteotomy as isolated treatment or concomitant with hip arthroscopy. Methods Case series study. Between 2014 and 2017, patients were included if they complained of hip pain and had a lateral center-edge angle ≤ of 20°. Exclusion criteria included an in-maturate skeleton, age of 40 or older, previous hip surgery, concomitant connective tissue related disease, and Tönnis osteoarthritis grade ≥ 1. All patients were studied before surgery with an anteroposterior pelvis radiograph, false-profile radiograph, and magnetic resonance imaging. Magnetic resonance imaging was used to assess intraarticular lesions, and if a labral or chondral injury was found, concomitant hip arthroscopy was performed. The non-parametric median test for paired data was used to compare radiological measures (anterior and lateral center-edge angle, Tönnis angle, and extrusion index) after and before surgery. Survival analysis was performed using revision to total hip arthroplasty as a failure. Kaplan Meier curve was estimated. The data were processed using Stata. Results A total of 15 consecutive patients were included; 14 (93%) were female patients. The median follow-up was 3.5 years (range, 2 to 8 years). The median age was 20 (range 13 to 32). Lateral center-edge angle, Tönnis angle, and extrusion index correction achieved statistical significance. Seven patients (47%) underwent concomitant hip arthroscopy; three of them (47%) were bilateral (10 hips). The labrum was repaired in six cases (60%). Three patients (15%) required revision with hip arthroplasty, and no hip arthroscopy-related complications are reported in this series. Conclusion To perform a hip arthroscopy concomitant with periacetabular osteotomy did not affect the acetabular correction. Nowadays, due to a lack of conclusive evidence, a case by case decision seems more appropriate to design a comprehensive treatment.

Dysplasia Of The Hip

Purpose Patients with developmental dysplasia of the hip (DDH) may require a pelvic osteotomy to treat acetabular dysplasia. The Pemberton osteotomy and modified San Diego acetabuloplasty are two options available when surgically treating DDH. The purpose of this study was to compare outcomes following the Pemberton and modified San Diego when treating patients with acetabular dysplasia in typical DDH. Methods We included 45 hips in the modified San Diego group and 38 hips in the Pemberton group. Hips with less than two years follow-up and patients with a neuromuscular diagnosis were excluded. Clinical outcomes were rated using the modified McKay criteria with radiographic outcomes graded using the Severin score. Avascular necrosis (AVN) was assessed using the Kalamchi and MacEwen criteria. Results Mean follow-up was 4.9 years (2.1 to 11.2). Both procedures produced similar decreases in the acetabular index (modified San Diego: 17.0˚ versus Pemberton: 15.2˚; p = 0.846). Most hips had good/excellent results using the modified McKay criteria (modified San Diego: 78%, Pemberton: 94%; p = 0.055). Most hips were rated as good/excellent on the Severin scale (modified San Diego: 100%, Pemberton: 97%, p = 0.485). The proportion of hips with AVN grade 2 or higher were similar between groups (modified San Diego: 0%, Pemberton: 3%; p = 0.458). Conclusion The modified San Diego acetabuloplasty is a safe and effective alternative to treat acetabular dysplasia in patients with typical DDH. By maintaining an intact medial cortex, acetabular reshaping can be customized to address each patient’s specific acetabular deficiency Level of evidence Level III retrospective comparison
