BACKGROUND:Monobloc advancement is a complex procedure used to treat patients with syndromic craniosynostosis. Studies directly addressing the long-term stability of monobloc advancement with distraction osteogenesis are underreported in the literature. The objectives of this study were to assess 5-year midface bone stability following monobloc advancement performed on patients with syndromic craniosynostosis, identify risk factors for relapse, and present strategies for prevention and management of complications. METHODS:An observational retrospective study was performed on consecutive patients with Apert, Crouzon, or Pfeiffer syndrome (n = 23) who underwent monobloc advancement using distraction osteogenesis between 1994 and 2013. A total of 130 lateral cephalograms were used to assess both long-term stability after monobloc advancement with distraction osteogenesis and risk factors for relapse. All serious complications were identified and recorded. The analysis of variance test was used to assess horizontal relapse of the midface and mandibular plane. RESULTS:Cephalometric analysis revealed long-term stability of frontofacial advancement using distraction osteogenesis, regardless of the presence of tested variables. Serious complications arising from monobloc advancement using distraction osteogenesis included cerebrospinal fluid leakage in six patients (26 percent), accompanying meningitis in two patients (8.7 percent), seizures in seven patients (30.4 percent), and impaired visual acuity in one eye of one patient (4.3 percent). CONCLUSION:Frontofacial monobloc advancement with distraction osteogenesis provides long-term midface bone stability. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, IV.


背景: Monobloc进展是用于治疗综合征性颅缝早闭患者的复杂程序。直接涉及牵张成骨整体推进长期稳定性的研究在文献中报道不足。本研究的目的是评估对综合征性颅缝早闭患者进行整体推进后的 5 年面中部骨稳定性,确定复发的危险因素,并提出预防和处理并发症的策略。 方法: 对 1994 年至 2013 年间接受牵张成骨整体推进术的连续Apert、Crouzon或Pfeiffer综合征患者 (n = 23) 进行了观察性回顾性研究。共使用 130 张头颅侧位片评估牵张成骨整体推进后的长期稳定性和复发风险因素。识别并记录所有严重并发症。采用方差分析检验评估面中部和下颌骨平面的水平复发。 结果: 头影测量分析显示,无论是否存在测试变量,使用牵张成骨的额面部前移的长期稳定性。牵张成骨整体推进引起的严重并发症包括脑脊液漏 6 例 (26%),伴发脑膜炎 2 例 (8.7%),癫痫 7 例 (30.4%),1 例患者单眼视力受损 (4.3%)。 结论: 额面部整体推进伴牵张成骨提供了长期的面中部骨稳定性。 临床问题/证据水平: 治疗性,IV。

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.
