摘要: |
目的: 探讨槌状指畸形磁性矫正器治疗槌状指畸形的可行性。方法: 将新鲜尸体手指标本植入相应大小的永磁铁钉,观察其伸指和屈指效果,分析此方法治疗槌状指畸形的可行性。结果: 5例手指标本剔除皮肤、筋膜等软组织,保留手指伸、屈指肌腱,置入永磁铁钉后,根据Dargan功能评定法评定手指关节功能:优3例,良1例,可1例,差0例,优良率为80%。15例手指标本在保留所有组织后,模拟临床进行手术,采用掌侧入路植入相应大小的永磁铁钉,根据Dargan功能评定法评定术后患指关节功能:优10例,良4例,可0例,差1例,评分优良率为93.3%。所有标本术后的屈指活动范围与术前无区别。结论: 槌状指畸形磁性矫正器治疗槌状指畸形具有可行性。 |

Abstract: |
Objective: To explore the feasibility of the magnetic correction device for the treatment of mallet finger deformity. Methods: The fresh cadaveric fingers were implanted with permanent magnet nails of corresponding size, and the effects of extending and flexing fingers were observed to analyze the feasibility of this method in treating mallet finger deformity. Results: The soft tissues such as skin and fascia were removed from 5 finger specimens, the finger extensions and flexor tendons were retained, and after the permanent magnet nails were placed, the postoperative function of the affected knuckles were evaluated according to Dargan function evaluation method:excellent in 3 cases, good in 1 case, fair in 1 case, and poor in 0 case. The excellent and good rate was 80%; 15 cadaveric fingers underwent simuiated clinical surgery after all tissues were retained, and permanent magnet nails of the corresponding size were implanted using the palmar approach, and the postoperative affected knuckles function evaluation results:excellent in 10 cases, good in 4 cases, fair in 0 case, and poor in 1 case, and the excellent and good rate was 93.3%. The ranges of flexion motion after operation were the same as those of before operation. Conclusions: The magnetic corrector is feasible for the treatment of mallet finger deformity, and its clinical effectiveness needs further research. |
