目的探讨关节镜下内固定关节融合术对晚期踝关节炎患者的疗效及美国矫形足踝协会评分系统(AOFAS)和疼痛视觉模拟评分(VAS)的影响。方法选取该院2012年1月-2015年1月收治的晚期踝关节炎患者84例,采用前瞻性研究的方法将研究对象随机分为实验组(42例)及对照组(42例),对照组患者采用传统开放性踝关节融合术,实验组在关节镜辅助下行内固定关节融合术。比较患者手术时间、术中出血量、术后住院时间和并发症发生率,同时随访12~36个月,采用AOFAS评分系统评估疗效,采用VAS评估患者踝关节疼痛程度。结果实验组的手术时间、术中出血量明显少于对照组(P0.05);两组患者术后情况对比,实验组术后住院时间及关节融合时间均少于对照组(P0.05);随访1年结果显示:实验组VAS及AOFAS评分均优于对照组(P0.05),实验组并发症发生率(9.52%)明显低于对照组(28.57%)(P0.05)。结论关节镜下内固定关节融合术手术时间短、术中出血量少、并发症发生率低,术后愈合率高,远期随访疗效确切,适合在临床推广使用。 相似文献

目的 通过比较两种不同手术切口对全膝关节表面置换术(TKA)术后外侧皮肤麻木的影响,为减少TKA术后切口外侧皮肤麻木提供参考,同时对麻木产生的原因做出诊断。方法 选取2021年1月至2021年9月于河北大学附属医院行初次膝关节置换术患者105名,随机分为A、B两组,采用不同手术切口,测量患者术后2周、1月、3月、6月、1年的皮肤麻木面积及麻木发生率,比较两种手术切口术后膝关节切口外侧皮肤麻木的差异。结果 改良手术切口术后皮肤麻木发生率小于经典手术切口,具有统计学意义(P<0.05);改良手术切口术后皮肤麻木面积小于经典手术切口(P<0.001);随时间变化,麻木面积总体呈现递减趋势,部分患者切口外侧麻木可完全恢复。结论 改良手术切口较经典手术切口术后切口外侧麻木发生率更小;改良手术切口较经典手术切口对于减少膝关节表面置换术后皮肤麻木发生率及麻木面积有积极的意义;TKA术后切口外侧皮肤麻木可诊断为隐神经髌下支损伤。 相似文献

BACKGROUND: There is evidence that internal fixation through an anterior or posterior approach for treatment of severe kyphotic deformity in spinal tuberculosis exhibits good curative effects. However, few prospective, long-term follow-up case control studies are reported. 相似文献

BACKGROUND: During the repair of thoracolumbar fracture, pedicle screw fixation is a commonly used treatment method. In the process of fixation, the different approaches can be used.
OBJECTIVE: To compare effect and biocompatibility of pedicle screw by percutaneous approach, posterior median approach, and intervertebral space approach for thoracolumbar fracture.
METHODS: 118 cases of thoracolumbar fracture were included after pedicle screw fixation. All patients were divided into three groups according to the approach: posterior median approach group (38 cases), intervertebral space approach group (40 cases) and percutaneous approach group (40 cases). After 12 months of follow-up, perioperative conditions, pain score, vertebral height of anterior border, kyphosis correction effect, adverse events and biological compatibility were compared among three groups.
RESULTS AND CONCLUSION: (1) Operation time, intraoperative bleeding and time in bed after surgery were shorter or less in the percutaneous approach and intervertebral space approach groups than in the posterior median approach group. Postoperative drainage was better in percutaneous approach and intervertebral space approach groups than in the posterior median approach group (all P < 0.05). Except drainage in the percutaneous approach and intervertebral space approach groups, no significant difference in other indicators was found. (2) Patients received imaging examination at different time points. The percentage of anterior vertebral height and kyphosis were significantly improved immediately after treatment and in final follow-up (all P < 0.05). No significant difference was detected before treatment, immediately after treatment and in final follow-up. (3) Visual Analogue score was identical before treatment. Visual analogue score was lower in the percutaneous approach and intervertebral space approach groups than in the posterior median approach group at 24 hours and 3 days after treatment and in final follow-up (all P < 0.05). No significant difference was detectable at 24 hours and 3 days after treatment and in final follow-up between the percutaneous approach and intervertebral space approach groups. (4) No rejection or wound non-healing was seen at 12 months after treatment. Some patients suffered from mild low back pain, which was improved by active symptomatic treatment. (5) These findings suggest that intervertebral space approach percutaneous approach obtained satisfactory outcomes compared with posterior median approach for treatment of thoracolumbar spine fractures, and good biocompatibility was found.

安瓿瓶作为注射剂的内包材,存在有许多难以避免的缺陷,这些缺陷将对人体造成不安全注射,由于没有很好的换代产品,几十年来一直沿用着,但随着人类对健康需求的日益重视,安瓿瓶的缺陷也越显突出.近年来卡式瓶的出现较好地解决了安瓿瓶作为注射剂内包材的缺陷,可以代替安瓿瓶作为注射剂的内包材. 相似文献

[目的]探讨病椎固定在脊柱结核患者治疗中的疗效.[方法]回顾性分析本院2009年1月到2014牟12月收治的脊柱结核患者84例,根据患者意愿分为两组.病椎间组:38例,固定在病变累及的单个神经单元中完成;超病椎间组:46例,采用长、短节段内固定,范围超出病灶外2个运动神经单元.比较两组患者的术中出血量、手术时间及术前、术后血沉(ESR)、C反应蛋白(CRP)、视觉模拟(VAS)评分及Frankel分级、Cobb角.[结果]病椎间组术中出血量及手术时间均优于超病椎间组,差异有统计学意义(P<0.05);两组患者ESR、CRP术后6个月均降低至正常水平,组间比较差异无统计学意义(P>0.05);病椎间组与超病椎间组末次随访时VAS评分较术前均下降,且低于超病椎间组,差异有统计学意义(P<0.05);两组患者Frankel功能分级较术前均明显恢复;两组患者末次随访时Cobb角均小于术前Cobb角.但两组间术前、术后、末次随访、矫正度数及丢失度数比较差异无统计学意义.[结论]病椎固定治疗脊柱结核是安全、有效的,能有效保留与病椎相邻正常运动神经单元,并有术中出血少、手术时间短的优势,值得临床推广应用. 相似文献
