AIMS:To monitor the performance of services for developmental dysplasia of the hip (DDH) in Northern Ireland and identify potential improvements to enhance quality of service and plan for the future. METHODS:This was a prospective observational study, involving all infants treated for DDH between 2011 and 2017. Children underwent clinical assessment and radiological investigation as per the regional surveillance policy. The regional radiology data was interrogated to quantify the use of ultrasound and ionizing radiation for this population. RESULTS:Evidence-based changes were made to the Northern Ireland screening programme, including an increase in ultrasound scanning capacity and expansion of nurse-led screening clinics. The number of infant hip ultrasound scans increased from 4,788 in 2011, to approximately 7,000 in 2013 and subsequent years. The number of hip radiographs on infants of less than one year of age fell from 7,381 to 2,208 per year. There was a modest increase in the treatment rate from 10.9 to 14.3 per 1,000 live births but there was a significant reduction in the number of closed hip reductions. The incidence of infants diagnosed with DDH after one year of age was 0.30 per 1,000 live births over the entire period. CONCLUSION:Improving compliance with the regional infant hip screening protocols led to reduction in operative procedures and reduced the number of pelvic radiographs of infants. We conclude that performance monitoring of screening programmes for DDH is essential to provide a quality service. Cite this article: Bone Joint J 2020;102-B(4):495-500.


目的: 监测北爱尔兰髋关节发育不良 (DDH) 服务的绩效,并确定潜在的改进措施,以提高服务质量并规划未来。 方法: 这是一项前瞻性观察性研究,涉及 2011 年至 2017 年期间接受DDH治疗的所有婴儿。根据区域监测政策,儿童接受了临床评估和放射学调查。询问区域放射学数据,以量化该人群超声和电离辐射的使用情况。 结果: 对北爱尔兰筛查方案进行了循证改革,包括增加超声扫描能力和扩大护士主导的筛查诊所。婴儿臀部超声扫描的数量从 2011 年的 4,788 次增加到 2013 年及其后几年的约 7,000 次。一岁以下婴儿的髋关节x线片数量从每年 7,381 片下降到 2,208 片。治疗率从每 10.9 例活产 14.3 例适度增加至 1,000 例,但闭合髋关节复位次数显著减少。在整个期间,一岁后诊断为DDH的婴儿发生率为每 0.30 例活产 1,000。 结论: 提高对区域性婴儿髋关节筛查方案的依从性导致手术操作减少,减少了婴儿骨盆x线片的数量。我们得出结论,DDH筛查方案的绩效监测对于提供优质服务至关重要。引用本文: 骨关节J 2020;102-B(4):495-500。

METHODS::Impairments in social cognition have been frequently described in 22q11.2 deletion syndrome (22q11.2DS) and are thought to be a hallmark of difficulties in social interactions. The present study addresses aspects that are critical for everyday social cognitive functioning but have received little attention so far. Sixteen children with 22q11.2DS and 22 controls completed 1 task of facial expression recognition, 1 task of attribution of facial expressions to faceless characters involved in visually presented social interactions, and 1 task of attribution of facial expressions to characters involved in aurally presented dialogues. All three tasks have in common to involve processing of emotions. All participants also completed two tasks of attention and two tasks of visual spatial perception, and their parents completed some scales regarding behavioural problems of their children. Patients performed worse than controls in all three tasks of emotion processing, and even worse in the second and third tasks. However, they performed above chance level in all three tasks, and the results were independent of IQ, age and gender. The analysis of error patterns suggests that patients tend to coarsely categorize situations as either attractive or repulsive and also that they have difficulties in differentiating emotions that are associated with threats. An isolated association between the tasks of emotion and behaviour was found, showing that the more frequently patients with 22q11.2DS perceive happiness where there is not, the less they exhibit aggressive behaviour.

METHODS:BACKGROUND:We describe the first radiographic clinic in the literature for DDH and how this novel clinic can significantly improve the efficiency and cost-effectiveness of service in a tertiary referral centre. AIMS:A radiographic clinic for the management of developmental dysplasia of the hip was introduced in 2017 in our institution. We performed a detailed cost analysis to assess the economic savings made with the introduction of this new clinic. We assessed the efficiency of the service by identifying how many unnecessary outpatient visits were prevented. We also assessed the difference in times from referral to review between the two clinics. METHODS:Analysis of the clinic activity in 2017 was possible as all data was collected prospectively by the DDH CNS and stored in our database. Cost analysis was performed, and the savings made per patient along with the financial benefit to our institution was recorded. RESULTS:The new radiographic clinic reduced the cost of reviewing one patient by €162.51 per patient. There was a 73% discharge rate from the clinic which prevented 251 unnecessary patient visits to the outpatient department over the course of the year. There was a significant 11-day reduction in waiting times between referral and review when comparing the radiographic to the conventional clinic (p < 0.05). CONCLUSIONS:A radiographic clinic for the management of developmental dysplasia of the hip has a significant effect on the efficiency and overall cost-effectiveness of service provision in a tertiary referral centre.

METHODS:INTRODUCTION:Triple pelvic osteotomy (TPO) involves periacetabular osteotomies of the ilium, ischium, and pubis to reorient the acetabulum. This operation is indicated in certain situations for the treatment of developmental dysplasia of the hip, dysplastic neuromuscular hips, and for containment of the femoral head in cases of Legg-Calvé-Perthes disease. METHODS:This retrospective cohort study compares radiographic outcomes of patients who underwent TPO using two different techniques and describes a novel single-incision direct lateral approach. TPO was performed on 22 patients by the senior author. The first 10 patients underwent TPO through a single-incision anterolateral approach. The last 12 patients underwent TPO using the direct lateral approach. Preoperative and postoperative pelvic radiographs were reviewed for each patient, and the migration index and center-edge angle were recorded. RESULTS:The migration index and center-edge angle were evaluated and were not found to be significantly different between the anterolateral and direct lateral groups. The direct lateral approach is described. CONCLUSION:The direct lateral approach for TPO is equivalent to the anterolateral approach on radiographic evaluation. Advantages of the direct lateral approach include direct visualization of the ischial osteotomy, effective mobilization of the acetabulum, and safety of the sciatic nerve.
