目的介绍采用微型骨腱骨带袢钢板(endobutton CL bone-tendon-bone,Endobutton CL BTB)伸肌腱止点重建治疗锤状指畸形的方法,并探讨其临床疗效。方法回顾性分析2010年1月至2013年8月21例我科收治锤状指畸形并采用微型骨腱骨带袢钢板治疗的患者资料,其中男15例,女6例,年龄18~45岁,平均(31.3±5.3)岁。受伤至手术时间为(5.2±2.1)d。所有患者均为伸肌腱止点断裂,无末节指骨基底撕脱性骨折。选择远侧指间关节背侧“S”形切口,于远节指骨背侧基底钻孔,将微型骨腱骨带袢钢板上肌腱缝合线自指腹穿入至指骨背侧基底穿出并拉紧后缝合伸肌腱近端以重建止点。术后及随访参照Crawford标准评估患指功能,测量患指及对侧健指各关节的主动屈伸活动范围,记录手指总的主动活动度;参照美国手外科协会总主动活动度(total action movement,TAM)系统评定手指功能。结果本组21例全部获得随访,随访时间8~24个月,平均(18.6±5.1)个月。手术时间为20~40 min,平均(29.6±10.3)min;术中出血量为5~10 ml,平均(7.5±2.6)ml。对比手术前后患指外观,20例锤状指畸形均矫正,1例出现背伸受限,伸直-20°。根据Crawford评定标准:优18例,良2例,优良率95.2%。伤指关节活动度:掌指关节为91°±7°,近指间关节92°±4°,远指间关节82°±8°,总主动活动度259°±15°;健侧TAM为259°±15°,患侧TAM268°±12°,差异有统计学意义(t=2.147,P=0.038)。根据TAM系统评定标准:优18例,良2例,优良率95.2%。术后1例出现背伸受限,1例因指腹手术瘢痕出现握持不适感,3例术后拔克氏针后背伸受限,术后6个月逐步恢复背伸功能。结论采用微型骨腱骨带袢钢板伸肌腱止点重建治疗锤状指畸形,手术操作简便,肌腱断端缝合可靠,术后患指可早期功能锻炼,疗效满意。
Objective Purpose To introduce the treatment of mallet finger deformity by reconstruction of the terminal extensor tendon insertion with endobutton CL bone-tendon-bone (BTB), and discuss its clinical effects. Methods From January 2010 to August 2013, 21patients (male 15, female 6) with mallet finger deformity were retrospectively studied. The average age of patients was 31.3±5.3 years. The time from injury to surgery was 5.2±2.1 d. Extensor tendons were ruptured at the terminal insertion in all patients, and there were no avulsion fracture at the base of the distal phalanx. the terminal extensor tendon insertion Awere surgical reconstructed with Endobutton CL BTB, via a dorsal S-shaped incision of distal interphalangeal joint. Dorsal base of the distal phalanx was drilled a hole and then the tendon suture line with Endobutton CL BTBwas inserted from the ventral finger to the dorsal base of the phalanx to suture the proximal extensor tendon. The function of the affected finger was evaluated according to the Crawford standard after operation and follow-up: the active flexion and extension range of motion of each joint of the affected finger and the contralateral healthy finger were measured, and the total active ranges of motion of the finger were recorded. Finger function was evaluated according to the total active range of motion (TAM) system of the American Association of hand Surgeons. Results All 21 cases were followed up and the follow-up period was 8 to 24 months, with an average of 18.6±5.1 months. The operation time of the patients was 20-40 min, with an average of 29.6±10.3 min. The intraoperative blood loss was 5-10ml, with an average of 7.5±2.6 ml. Mallet finger deformities were all corrected postoperatively. One case presented with limited dorsal extension with elongation of -20°. According to the Crawford evaluation standard, there were 18 excellent patients and 2 good patients, with the excellent and good rate was 95.2%(20/21). The degrees of active joint activity were: 91°±7° of the metacar
