目的 探讨关节镜微创技术治疗外伤导致的创伤性掌指关节疼痛、功能障碍早中期的临床疗效.方法 自2016年3月至2018年12月,我们对9例外伤导致的创伤性掌指关节炎早中期患者采用关节镜下微创治疗,直观了解掌指关节病变,同时清理关节面增生的骨赘、关节内游离体、滑膜炎.术后指导患者渐进性功能锻炼,随访患指关节活动度,观察指体有无肿胀、畸形和疼痛.结果 术后随访时间为6～24个月,平均15个月,所有患者短期内均未出现手术并发症和疼痛不适等症状,关节屈伸功能均有不同程度改善,按手指屈伸功能总主动活动度(total active motion,TAM)测定标准:术前良1例,中5例,差3例;术后优6例,良2例,中1例.结论 对于早中期掌指关节创伤性关节炎导致的关节疼痛、功能障碍等病变,关节镜下微创治疗具有创伤小、治疗准确性和针对性较高、术后恢复快等优点,是一种有效改善手功能、减轻关节疼痛的治疗手段,值得临床推荐.“,”Objective To explore the clinical efficacy of arthroscopic minimally invasive technique in the treatment of traumatic pain and dysfunction of metacarpophalangeal joint in the early and middle stages.Methods From March 2016 to December 2018,nine patients with traumatic metacarpophalangeal arthritis were treated with arthroscopic minimally invasive assistance to understand the lesions of metacarpophalangeal joint,and to clean up the osteophytes,intra-articular free bodies and synovitis.After the operation,the patients were instructed to take progressive functional exercise.The joint motion degree of the affected fingers was followed up.Whether there were swelling,deformity and pain in the fingers was observed.Results The postoperative follow-up time ranged from 6 to 24 months,with an average of 15 months.All the patients did not have any symptoms such as surgical complications and pain discomfort in a short period of time.The joint flexion and extension function were improved in varying degrees.According to the measurement standard of total active motion (TAM) of finger flexion and extension function,before operation the results were good in 1 case,fair in 5 cases and poor in 3 cases;after operation the results were excellent in 6 cases,good in 2 cases and fair in 1 case.Conclusion In the early and middle stage of traumatic arthritis of metacarpophalangeal joint,the minimally invasive treatment under arthroscope has the advantages of small trauma,high accuracy and pertinence,quick postoperative recovery,which is an effective treatment method to improve hand function and reduce joint pain,and is worthy of clinical promotion.
