[目的]比较肱二头肌长头腱切断固定术和上盂唇锚钉缝合修复术治疗II型SLAP损伤的临床疗效。[方法]回顾性分析本院2018年1月—2021年6月收治的31例II型SLAP损伤患者的临床资料,根据医患沟通结果,16例采用肱二头肌长头腱切断固定术治疗(腱固定组),15例采用带线锚钉缝合修复术(修复组),比较两组围手术期及随访结果。[结果]两组均顺利完成手术,两组手术时间、切口长度、术中失血量、主动活动时间、切口愈合和住院时间比较的差异均无统计学意义(P>0.05)。两组均获得至少1年的随访。两组完全负重活动时间的差异无统计学意义(P>0.05)。术后随时间推移,两组VAS、ASES、QuickDASH和Constant-Murley评分均显著改善(P<0.05)。术后3个月,腱固定组的VAS评分[(2.5±0.5) vs (3.7±1.0), P<0.001]显著优于修复组。末次随访,腱固定组的ASES [(93.7±1.8) vs (90.3±3.3), P=0.002]、QuickDASH [(8.9±1.9) vs (11.0±1.6), P=0.002]和Constant-Murley评分[(93.8±1.5) vs (91.1±3.1), P=0.006]均显著优于修复组,但两组VAS评分的差异已无统计学意义(P>0.05)。[结论]肱二头肌长头腱切断固定术和上盂唇的带线锚钉缝合修复术在治疗II型SLAP损伤上均有良好的效果,相比之下,肱二头肌长头腱切断固定术在患者术后半年的体验及疗效,较修复术更优。
Feature Selection(FS)is a key pre-processing step in pattern recognition and data mining tasks,which can effectively avoid the impact of irrelevant and redundant features on the performance of classification models.In recent years,meta-heuristic algorithms have been widely used in FS problems,so a Hybrid Binary Chaotic Salp Swarm Dung Beetle Optimization(HBCSSDBO)algorithm is proposed in this paper to improve the effect of FS.In this hybrid algorithm,the original continuous optimization algorithm is converted into binary form by the S-type transfer function and applied to the FS problem.By combining the K nearest neighbor(KNN)classifier,the comparative experiments for FS are carried out between the proposed method and four advanced meta-heuristic algorithms on 16 UCI(University of California,Irvine)datasets.Seven evaluation metrics such as average adaptation,average prediction accuracy,and average running time are chosen to judge and compare the algorithms.The selected dataset is also discussed by categorizing it into three dimensions:high,medium,and low dimensions.Experimental results show that the HBCSSDBO feature selection method has the ability to obtain a good subset of features while maintaining high classification accuracy,shows better optimization performance.In addition,the results of statistical tests confirm the significant validity of the method.
目的探讨关节镜下带线锚钉修补术治疗Ⅴ型由前至后盂唇(superior labral anterior to posterior,SLAP)损伤的手术技术并观察临床疗效。方法回顾性分析2013年1月至2018年6月共12例Ⅴ型SLAP损伤患者,采用关节镜下带线锚钉技术修补盂唇,术后随访1年,手术前后采用疼痛视觉模拟评分(visual analogue scale,VAS)、关节活动度(range of motion,ROM)、Rowe评分和美国肩肘协会评分(American shoulder and elbow surgeons,ASES)等评估手术效果。结果12例患者VAS评分术前和术后6个月、术后1年相比差异均有统计学意义(P<0.05)。ROM(外旋)术后6个月与健侧相比差异具有统计学意义(P<0.05),术后1年与健侧相比差异无统计学意义(P>0.05)。Rowe和ASES评分术前和术后1年相比差异均有统计学意义(P<0.05)。结论关节镜下带线锚钉修补手术治疗Ⅴ型SLAP损伤能够改善患者肩关节疼痛和功能,具有良好临床疗效。
