关节镜监视下微创治疗良性骨肿瘤

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.

Arthroscopic minimally invasive surgery for treating benign bone tumor

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 .
