关节镜监视下微创治疗良性骨肿瘤

摘要

目的 探讨关节镜监视下微创局部切除良性骨肿瘤的效果.方法 2011年8月到2012年12月对8例良性骨肿瘤患者采用关节镜监视下微创治疗.其中骨软骨瘤3例 ,骨囊肿2例 ,非骨化性纤维瘤1例 ,骨样骨瘤2例.根据术前影像学资料定位 ,置入关节镜及刨刀进入病灶区 ,在关节镜监视下局部切除肿瘤 ,并用等离子刀处理切除肿瘤后创面 ,对存在骨缺损病例以同种异体骨充填.结果 8例患者术后恢复良好 ,入路切口小于3个 ,切口长度小于1 .5 cm ,其中2例充填同种异体骨.随访8~12个月 ,平均10个月 ,无复发、骨折及功能障碍 ;术后X线片显示病变切除彻底 ,骨缺损病灶同种异体骨充填完全.结论 深部骨良性肿瘤在关节镜监视下可以最大限度保留局部解剖结构.%Objective To investigate the effecof arthroscopiminimally invasion fothe local excision of benign bone tumo.MethodEighpatientwith benign bone tumofrom Augus2011 to Decembe2012 were treated by arthroscopimini-mally invasive operation ,including 3 caseof osteochondrom,2 caseof bone cys,1 case of non-ossifying fibromand 2 caseof osteoid osteom.The lesion location wadetermined by the preoperative imaging dat,the arthroscope and plane cuttewere placed into the lesion arethe tumowaperformed the local lesion resection undethearthroscopimonitoring ,then the plasmwaadopt-ed to treathe resected wound surface of tumo,the bone defectwere implanted by allogeneibone .ResultEighcasewere re-covered well afteoperation .No postoperative complicationwere found .The approach incision ＜3 and the wound length ＜1 .5 cm .Two casewere filled with allogeneibone .There were no recurrence ,fracture odyfunction during the average follow up peri-odof 8-12 month.The postoperative X-ray showed thathe lesion wacompletely resected and the bone defeclesion wacom-pletely filled with allogeneibone .Conclusion The resection of deep benign bone tumoundethe arthroscopimonitoring can maximize to retain the local anatomistructure .
