[目的]探讨Depuy椎弓根钉棒系统联合后路环形植骨融合治疗腰椎滑脱症的临床疗效。[方法]2007年1月~2010年1月,58例腰椎滑脱症患者均采用Depuy椎弓根钉棒系统联合后路环形植骨融合进行治疗,分别比较术前、术后1周和随访末次随访椎间隙高度、滑脱角、Boxall指数及腰椎生理前凸角。腰椎功能改善情况采用日本骨科协会评分标准(Japanese Orthopaedics Association,JOA)评估。[结果]58例患者术后均获24~60个月随访。根据Nakai评分标准,优49例,良8例,可1例,优良率达98.3%。术前JOA评分为(13.21±1.41)分,术后1周JOA评分为(24.27±1.23)分,末次随访JOA评分为(25.35±1.31)分。术前与术后1周、末次随访比较差异有统计学意义(P<0.05)。本组患者3~12个月内均获得骨性融合,无Cage融合器移位或沉陷,椎弓根钉棒松动、移位、断裂,甚至滑脱复发等并发症发生。术后1周椎间隙高度、滑脱角、Boxall指数及腰椎生理前凸角与术前比较差异有统计学意义(P<0.05);而术后1周与末次随访各指标比较差异无统计学意义(P>0.05)。[结论]Depuy椎弓根钉棒系统联合后路环形植骨融合治疗腰椎滑脱症,固定牢靠,复位满意,融合率高,是治疗腰椎滑脱症较为理想的方法。 展开更多

The Johnson and Johnson faulty hip implant case represents one of the most significant crises in medical device history,impacting nearly 93000 patients worldwide.In response to alarming failure rates and a global recall in August 2010,countries such as Australia,the United States,and the United Kingdom quickly implemented revision surgeries and reimbursement programs to protect patient safety.In stark contrast,India's response was alarmingly delayed;defective implants continued to be sold even after the global recall.By the time the import license was revoked,and the Central Drugs Standard Control Organization issued a recall notice,these implants had already been involved in 4700 surgeries across India.This paper explores the systemic weaknesses in India’s medical device regulatory framework that contributed to this delayed action,resulting in many patients suffering from serious health complications.It highlights deficiencies in monitoring and reporting mechanisms,inadequate regulatory oversight,and insufficient approval processes.Furthermore,the inability to trace affected patients and provide necessary compensation underscores significant gaps in regulation.Although subsequent legislative reforms were introduced,this paper argues that substantial loopholes remain,posing risks for future incidents.Thus,urgent,comprehensive,and enforceable regulatory measures are needed to increase patient safety. 展开更多
