Abstract

BACKGROUND:Patients with recurrent clubfoot may seek intervention to address impairments that impact gait function. An understanding of these impairments and associated gait issues will provide valuable information about ongoing treatment requirements. RESEARCH QUESTION:The purpose of this study was to describe the prevalence of impairments and associated gait deviations in children with recurrent clubfoot and to evaluate whether these findings differ depending on unilateral or bilateral presentation. METHODS:Eighty-four affected feet (42 unilateral, 21 bilateral) were retrospectively reviewed. History, clinical exam, and gait data were collected. Statistical analysis included evaluations of associations between clinical exam and gait parameters and differences among patients with unilateral versus bilateral clubfoot and a database of healthy controls. RESULTS:The average age was 7.5 ± 3.3 years for unilateral and 7.0 ± 2.8 years for bilateral patients. Patients presented with limited passive ankle dorsiflexion (unilateral/bilateral:67%/57%), limited ankle plantar flexion strength (unilateral/bilateral:53%/55%), metatarsus adductus (unilateral/bilateral:86%/83%) and internal foot-thigh angles (unilateral/bilateral:83%/82%), while only a subset presented with internal bi-malleolar axis angles (unilateral/bilateral:36%/45%). The most common gait deviations were internal foot progression (unilateral/bilateral:76%/73%), external hip rotation (unilateral/bilateral:66%/69%), reduced peak ankle plantar flexion moments (unilateral/bilateral:84%/83%), and reduced peak ankle power generation (unilateral/bilateral:67%/74%). Passive dorsiflexion was significantly correlated with peak dorsiflexion during stance and swing in both groups. Patients with unilateral compared to bilateral clubfoot showed decreased peak dorsiflexion and an associated knee flexor moment. SIGNIFICANCE:Patients with recurrent clubfoot show gait deviations at the ankle that can be explained by joint level impairment and compensations at the knee, hip and pelvis. Patients with unilateral clubfoot typically show decreased dorsiflexion range of motion and associated greater gait impacts and compensations than bilateral clubfoot. Understanding the relationships between impairments and gait function and the implications of unilateral versus bilateral clubfoot will help improve prognostic ability and optimize future treatment outcomes.

摘要

背景: 复发性马蹄内翻足患者可能会寻求干预,以解决影响步态功能的损伤。对这些损伤和相关步态问题的理解将提供关于正在进行的治疗需求的有价值的信息。 研究问题: 本研究的目的是描述复发性马蹄内翻足患儿损伤和相关步态偏差的患病率,并评估这些发现是否因单侧或双侧表现而不同。 方法: 回顾性分析 84 只受累足 (42 只单侧,21 只双侧)。收集病史、临床检查和步态数据。统计分析包括评价临床检查和步态参数之间的相关性,以及单侧与双侧马蹄内翻足患者和健康对照数据库之间的差异。 结果: 单侧患者平均年龄为 7.5 ± 3.3 岁,双侧患者平均年龄为 7.0 ± 2.8 岁。患者表现为踝关节被动背屈受限 (单侧/双侧: 67%/57%),踝关节跖屈力量受限 (单侧/双侧: 53%/55%),跖骨内收 (单侧/双侧: 86%/83%) 和足-大腿内角 (单侧/双侧: 83%/82%),而只有一个子集呈现内部双踝轴角 (单侧/双侧: 36%/45%)。最常见的步态偏差为内足进展 (单侧/双侧: 76%/73%),外髋旋转 (单侧/双侧: 66%/69%),降低峰值踝跖屈力矩 (单侧/双侧: 84%/83%),降低峰值踝发电 (单侧/双侧: 67%/74%)。在两组中,被动背屈与站立和摆动时的峰值背屈显著相关。与双侧马蹄内翻足相比,单侧患者表现出峰值背屈减少和相关的膝关节屈肌力矩。 意义: 复发性马蹄内翻足患者表现出踝关节处的步态偏差,可以用膝关节、髋关节和骨盆处的关节水平损伤和代偿来解释。单侧马蹄内翻足患者通常比双侧马蹄内翻足表现出背屈活动范围减小,并伴有更大的步态冲击和补偿。了解损伤和步态功能之间的关系以及单侧与双侧马蹄内翻足的影响将有助于改善预后能力和优化未来的治疗结果。

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.
