Though a bone/metal interface in osseointegration was also formed on the surface of uncoated 317L plate screw after implantation, a smal1 space was seen between the bone and surface of the screw, indicating that the tissue compatibility of titanium-coated 317L plate screw may be better than that of the non-coated screw.展开更多
目的探讨空心无头加压螺钉钛缆张力带内固定术对髌骨骨折(patellar fracture,PF)患者并发症及膝关节功能的影响。方法选取2020年6月至2022年2月平度市第三人民医院收治的92例PF患者作为研究对象,按照随机数字表法分为对照组与观察组,每...目的探讨空心无头加压螺钉钛缆张力带内固定术对髌骨骨折(patellar fracture,PF)患者并发症及膝关节功能的影响。方法选取2020年6月至2022年2月平度市第三人民医院收治的92例PF患者作为研究对象,按照随机数字表法分为对照组与观察组,每组46例。对照组予以克氏针钢丝张力带内固定术治疗,观察组予以空心无头加压螺钉钛缆张力带固定术治疗。比较两组围手术期指标、临床疗效、并发症发生情况、疼痛情况[视觉模拟评分法(visual analogue scale,VAS)评分]、膝关节功能及生命质量[生命质量综合评定问卷(generic quality of life inventory-74,GQOLI-74)评分]。结果两组术中失血量、手术时间及住院时间比较差异无统计学意义;观察组下床活动时间短于对照组,差异有统计学意义(P<0.05)。观察组治疗总有效率为95.65%,高于对照组的82.61%,差异有统计学意义(P<0.05)。观察组并发症发生率为4.35%,低于对照组的19.57%,差异有统计学意义(P<0.05)。治疗后,观察组VAS评分低于对照组,差异有统计学意义(P<0.05)。治疗后,观察组疼痛程度、工作能力、肌萎缩程度、关节活动范围、辅助物使用及积液情况评分均高于对照组,差异有统计学意义(P<0.05)。治疗后,观察组物质生活、社会功能、生理及心理功能评分均高于对照组,差异有统计学意义(P<0.05)。结论空心无头加压螺钉钛缆张力带内固定术治疗PF疗效显著,可缩短患者术后恢复时间,减少并发症发生,减轻术后疼痛,促进膝关节功能恢复,提高患者生命质量,值得临床推广应用。展开更多
