Hip Displacement in Cerebral Palsy: The Role of Surveillance

IntroductionHip displacement is common in cerebral palsy (CP) and is related to the severity of neurological and functional impairment. It is a silent, but progressive disease, and can result in significant morbidity and decreased quality of life, if left untreated. The pathophysiology of hip displacement in CP is a combination of hip flexor-adductor muscle spasticity, abductor muscle weakness, and delayed weight-bearing, resulting in proximal femoral deformities and progressive acetabular dysplasia. Due to a lack of symptoms in the early stages of hip displacement, the diagnosis is easily missed. Awareness of this condition and regular surveillance by clinical examination and serial radiographs of the hips are the key to early diagnosis and treatment.Hip surveillance programmesSeveral population-based studies from around the world have demonstrated that universal hip surveillance in children with CP allows early detection of hip displacement and appropriate early intervention, with a resultant decrease in painful dislocations. Global hip surveillance models are based upon the patients’ age, functional level determined by the Gross Motor Function Classification system (GMFCS), gait classification, standardized clinical exam, and radiographic indices such as the migration percentage (MP), as critical indicators of progressive hip displacement.ConclusionDespite 25 years of evidence showing the efficacy of established hip surveillance programmes, there is poor awareness among healthcare professionals in India about the importance of regular hip surveillance in children with CP. There is a need for professional organizations to develop evidence-based guidelines for hip surveillance which are relevant to the Indian context.     

利用微信平台延续性护理对老年腰椎间盘突出症术后患者康复及生活质量的影响

目的探讨微信平台延续性护理对老年腰椎间盘突出症术后患者康复及生活质量的影响。方法选取2015年6月—2018年5月在郑州市骨科医院接受手术治疗的老年腰椎间盘突出症患者96例进行研究。对照组行常规延续性护理,观察组行微信平台延续性护理。对比两组康复效果、治疗依从性及生活质量。计数资料采用卡方检验分析,计量资料采用t检验分析。结果观察组有效率为95.83%,明显高于对照组的81.25%。观察组总依从率为91.67%,明显高于对照组的77.08%。干预前两组生活质量量表得分相当,治疗后两组生活质量均有明显改善,但观察组改善程度更为明显。结论微信平台延续性护理相比传统延续性护理可明显提高老年腰椎间盘突出症患者康复效果、提高治疗依从性和改善生活质量。

小角度弯曲针法介入治疗腰5-骶1椎间盘突出症

目的探讨小角度弯曲针穿刺法进行腰5-骶1椎间盘或低位腰4~5椎间盘介入治疗的方法和应用效果。方法对50例明显低于髂嵴的腰4-5或腰5-骶1椎间盘突出症患者采取小角度弯曲针法穿刺椎间盘进行介入治疗。透视下旋转血管机的C型臂,使射线方向与椎间隙平行,将皮肤穿刺点位于距离脊柱中线6~8cm处,常规消毒麻醉;将穿刺针的前端2~3cm向一侧弯曲20°后向椎间盘穿刺,侧位观察接近椎间盘后缘时,将穿刺针弯曲端偏向内侧、上方进入椎间盘后外侧部,然后进行椎间盘内臭氧注射或等离子消融治疗。结果椎间盘穿刺顺利,一次穿刺成功者45例,占90%,穿刺针进入椎间隙后多数与椎间隙平行,利于盘内介入操作(40/50,占80%),仅20%穿刺后针尖位置欠理想,但尚可完成臭氧注射溶核。经穿刺针向盘内注射臭氧分布良好,等离子刀头活动范围适合消融需要,手术后近期有效率96%,无明显穿刺并发症。结论小角度弯曲针法可以避免高位髂嵴对低位椎间盘穿刺的限制,提高穿刺针在椎间盘内的位置精度,有利于顺利施行介入处理,减少穿刺损伤,缩短手术时间。     

Nonoperatively treated burst fractures of the thoracic and lumbar spine in adults: a 23- to 41-year follow-up

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fractured vertebra, often damaged at injury and possibly at an increased risk of height reduction and degeneration with subsequent chronic back pain. PURPOSE: To evaluate the long-term clinical and radiological outcome after nonoperatively treated thoracic or lumbar burst fractures in adults, with special attention to posttraumatic radiological disc height reduction. STUDY DESIGN: Case series. PATIENT SAMPLE: Sixteen men with a mean age of 31 years (range, 19-44) and 11 women with a mean age of 40 years (range, 23-61) had sustained a thoracic or lumbar burst fracture during the years 1965 to 1973. Four had sustained a burst fracture Denis type A, 18 a Denis type B, 1 a Denis type C, and 4 a Denis type E. Seven of these patients had neurological deficits at injury, all retrospectively classified as Frankel D. OUTCOME MEASURES: The clinical outcome was evaluated subjectively with Oswestry score and questions regarding work capacity and objectively with the Frankel scale. The radiological outcome was evaluated with measurements of local kyphosis over the fractured segment, ratios of anterior and posterior vertebral body heights, adjacent disc heights, pedicle widths, sagittal width of the spinal canal, and lateral and anteroposterior displacement. METHODS: From the radiographical archives of an emergency hospital, all patients with a nonoperatively treated thoracic or lumbar burst fracture during the years 1965 to 1973 were registered. The fracture type, localization, primary treatment, and outcome were evaluated from the old radiographs, referrals, and reports. Twenty-seven individuals were clinically and radiologically evaluated a mean of 27 years (range, 23-41) after the injury. RESULTS: At follow-up, 21 former patients reported no or minimal back pain or disability (Oswestry Score mean 4; range, 0-16), whereas 6 former patients (of whom 3 were classified as Frankel D at baseline) reported moderate or severe disability (Oswestry Score mean 39; range, 26-54). Six former patients were classified as Frankel D, and the rest as Frankel E. Local kyphosis had increased by a mean of 3 degrees (p<.05), whereas the discs adjacent to the fractured vertebrae remained unchanged in height during the follow-up. CONCLUSIONS: Nonoperatively treated burst fractures of the thoracic or lumbar spine in adults with or without minor neurological deficits have a predominantly favorable long-term outcome, and there seems to be no increased risk for subsequent disc height reduction in the adjacent discs.

经皮激光椎间盘减压术治疗颈性眩晕的临床研究

目的探讨经皮激光椎间盘减压术治疗颈性眩晕的疗效及机制。方法对31例颈性眩晕患者36个突出间盘行经皮激光椎间盘减压术，观察术后3个月以上的疗效。结果28例术后眩晕立即消除(90％)，明显改善者2例(7％)，无效者1例(3％)，无神经损害、感染等并发症发生。结论导致颈性眩晕的主要原因是颈椎间盘突出、颈椎失稳，激惹交感神经诱发椎动脉痉挛。钩突关节肥大并非是主要致病因素。经皮激光椎间盘减压术使椎间盘内压骤然降低，加之局部直接热疗，从而可消除椎动脉痉挛，对治疗颈性眩晕有明显疗效。

胸腰段椎间盘突出症诊断的临床研究

目的探讨胸腰段椎间盘突出症临床表现的特点与规律，提高胸腰段椎间盘突出症的诊断水平。方法回顾性分析1995年9月～2004年1月我院经X线、CT、MRI及手术证实的胸腰段椎间盘突出症65例的临床资料，并将其分为低位胸椎组（T10-T12L1）43例，高位腰椎组（L1-2-L2-3）16例，多节段突出组6例。结果躯体感觉障碍89．2％（58／65）和下肢无力83．1％（54／65）是最多见的症状。9．2％（6／65）表现为上运动神经元损害，47．7％（31／65）表现为下运动神经元损害，43．1％（28／65）表现为上、下运动神经元混合性损害。仅3例为单根神经根损害，其余表现为多根神经或马尾神经的损害。腰背痛44．6％（29／65）和下肢无力40．0％（26／65）是最常见的首发症状。低位胸椎间盘突出以混合性运动神经元损害为主，占58．1％（25／43），易导致行走障碍、足下垂、下肢肌张力升高和病理征阳性；而高位腰椎间盘突出则以下运动神经元损害为主，占93．8％（15／16），易造成腰背、下肢疼痛及马尾神经损害。结论胸腰段椎间盘突出症的症状广泛、体征多样，当临床上存在以下情况时应高度怀疑胸腰段椎间盘突出症：①大腿前方、外侧或腹股沟部位出现感觉障碍者；②下肢无力，股四头肌，胫前肌肌力减退者（如足下垂）；③下肢运动或感觉障碍范围广泛、不规则，缺乏根性分布特征者；④上、下运动神经元损害同时存在，或虽表现为下运动神经元损害，但难以用低位腰椎间盘突出症解释者。
