  • 舟骨月骨间韧带损伤修复早期效果

    目的 评价采用骨锚治疗舟骨月骨间韧带损伤的早期临床效果。 方法 2005 年9 月- 2008 年12 月, 采用Mitek 骨锚修复9 例舟骨月骨间韧带损伤,其中男8 例,女1 例;年龄24 ~ 40 岁,平均31 岁。受伤距韧带修复时间为7 ~ 40 d,平均22 d。9 例经X 线片检查均符合舟骨月骨间韧带损伤诊断标准。术后定期随访,包括疼痛程度、腕关节活动度、双手握力及X 线片检查。腕关节总体功能评价采用Krimmer 腕关节评分表。患者自我功能评价采用患者源性功能调查表上肢功能(DASH)评定表。 结果 患者术后切口均Ⅰ期愈合。9 例均获随访,随访时间7 ~ 18 个月,平均10 个月。术后6 个月X线片检查示舟骨月骨间隙及舟月角分别为(2.8 ± 0.7)mm、(53 ± 9)°,较术前的(5.1 ± 0.8) mm、(80 ±13)° 明显减小,差异有统计学意义(P lt; 0.05)。术后12 个月腕关节屈伸活动度为(97 ± 16)°,术前为(60 ± 10)°;尺桡偏活动度为(55 ± 12)°,术前为(32 ± 9)°;双手握力为(36 ± 7)kg,术前为(28 ± 6)kg;腕关节疼痛视觉模拟评分(VAS)为(21.0 ± 5.2)分,术前为(43.0 ± 11.0)分;以上各指标手术前后比较差异均有统计学意义(P lt; 0.05)。术后18 个月腕关节总功能Krimmer 评分为(82 ± 12)分,其中优4 例,良4 例,中1 例,与术前(56 ± 10)分比较差异有统计学意义(P lt; 0.05)。术后12 个月DASH 评分为(23 ± 12)分,术前为(42 ± 14)分,手术前后比较差异有统计学意义(P lt; 0.05)。 结论 骨锚修复舟骨月骨间韧带能恢复舟月骨稳定性,术后腕关节功能明显改善。

  • Kirschner WIRE FIXATION IN THREE JOINTS COMBINED WITH BONE ANCHOR REPAIR FOR TREATMENT OF ACUTE PERILUNATE INJURY

    ObjectiveTo investigate the effectiveness of Kirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint combined with bone anchor repair for the treatment of acute perilunate injury. MethodsBetween January 2007 and January 2012, 35 cases of acute perilunate injury were treated. There were 30 males and 5 females with an average age of 45.5 years (range, 32-56 years). Fractures were caused by falling from height in 18 cases, by traffic accident in 11 cases, and by fall injury in 4 cases. The time from injury to operation was 2-6 days (mean, 3.4 days). There were 23 cases of trans-scaphoid perilunate dislocation, 10 cases of perilunate dislocation, and 2 cases of trans-triangular perilunate dislocation. Associated injuries included median nerve injury in 6 cases, radius styloid fracture in 8 cases, ulnar styloid fracture in 2 cases, and distal tibial fracture in 1 case. All the patients were treated by open reduction, Herbert screw fixation of scaphoid fractures, and Kirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint, and the intercarpal ligaments were repaired by Mitek bone anchor. ResultsSuperficial wound infection occurred in 2 cases, and primary healing of incision obtained in others. Thirty-five patients were followed up 12-35 months (mean, 18 months). X-ray films showed fracture union in 21 cases of scaphoid fractures, and bone nonunion in 2 cases of scaphoid fractures. During the follow-up period, there was no avascular necrosis of scaphoid or lunate. At last follow-up, the scapholunate angle, radiolunate angle, and wrist range of motion (ROM) in extension had no significant difference between affected and unaffected sides (P > 0.05). The wrist ROM in flexion and grip strength of affected side were not up to the levels of unaffected side (P < 0.05). According to the modified Mayo wrist scoring system, the score was 79.9±10.7, which were excellent in 8 cases, good in 17 cases, fair in 7 cases, and poor in 3 cases, and the excellent and good rate was 71.4%. The disability of arm-shoulder-hand (DASH) questionnaires score was 21±10. Traumatic osteoarthritis was observed in 2 cases. ConclusionKirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint combined with bone anchor repair for the treatment of acute perilunate injury can get early stability of the carpal joint, favorable intercarpal ligament repair, and good recovery of wrist joint function.

  • EFFECTIVENESS OF KNEE EXTENSOR MECHANISM RECONSTRUCTION FOR RECURRENT PATELLAR SUBLUXATION WITH BONE ANCHOR IN ADOLESCENTS

    ObjectiveTo explore the effectiveness of knee extensor mechanism reconstruction in the treatment of recurrent patellar subluxation with bone anchor in adolescents. MethodsBetween January 2010 and December 2013, 20 patients with patellar subluxation were treated by knee extensor mechanism reconstruction with bone anchor. There were 11 males and 9 females, aged from 12 to 17 years (mean, 15.3 years). The left knee was involved in 12 cases and the right knee in 8 cases. The disease duration was 5-10 years (mean, 7 years). All the patients had knee pain and lateral subluxation of the patella. Preoperative Lysholm knee score was 71.4±4.7. All the patients received the MRI examination to exclude menisci or ligaments lesion. CT examination showed the tibial tuberosity trochlear groove spacing ranged from 15 to 20 mm (mean, 17 mm). X-ray film examination indicated that no varus or valgus was observed, and bony structure was normal. ResultsAll the incisions healed at first stage. The patients received follow-up of 12-24 months (mean, 13 months). Knee pain occurred in 2 cases and were cured after symptomatic treatment. The axial X-ray films showed good position of the patella and normal anatomic relationship of the patellofemoral joint. No anchor loosening and pulling out, internal fixation failure, pseudoarthrosis formation, and postoperative recurrent patellar subluxation occurred during follow-up. At 1 year, the Lysholm knee score was significantly improved to 94.2±3.4 (t=22.705, P=0.000). According to Insall criterion, the results were excellent in 9 cases, good in 9 cases, and fair in 2 cases, with an excellent and good rate of 90%. ConclusionThe bone anchor for extensor mechanism reconstruction is a convenient and reliable way to treat the recurrent patellar subluxation, with a satisfactory early effectiveness and less complications; however, its long-term effectiveness is required a further follow-up.
