Abstract

BACKGROUND:Although adjacent segment disease (ASD) following anterior cervical fusion has been well described in the literature, there is relative paucity of data on this pathology after posterior cervical fusion. To our knowledge, there have been no reported cases of proximal ASD following posterior fusion to C2. CASE DESCRIPTION:We present 2 cases of proximal ASD presenting as retroodontoid pseudotumors following posterior fusion to C2, both in middle-aged females without history of rheumatologic disease. The first occurred in a patient with Klippel-Feil deformity 13 years after C2-6 posterior cervical fusion, the second in a patient 3 and a half years following revisional circumferential C2-T2 fusion. Both were successfully treated with proximal extension of laminectomy and fusion to the occiput, supplemented in the first patient by transdural decompression of retroodontoid mass. CONCLUSIONS:Proximal ASD can manifest as retroodontoid pseudotumor at variable time intervals following posterior fusion to C2. Clinicians must account for this possibility in their decision making.

摘要

背景: 尽管颈椎前路融合术后邻近节段疾病 (ASD) 在文献中已有较好的描述,但颈椎后路融合术后这种病理资料相对较少。据我们所知,在c2 后路融合术后,没有报告近端ASD的病例。 病例描述: 我们报告 2 例近端ASD,表现为C2 后路融合后齿状突后假瘤,均为中年女性,无风湿病史。第一次发生在患者Klippel-Feil畸形 13 年后C2-6 后路寰枢椎融合,第二个在患者 3 年半后revisional圆周C2-T2 融合.两组均成功接受椎板近端延伸切除融合至枕骨,并在第一例患者中辅以齿状突后肿块的硬脑膜减压术。 结论: 近端ASD在后路与c2 融合后可以以不同的时间间隔表现为齿状突后假瘤。临床医生在决策时必须考虑这种可能性。

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.
