Abstract

Objective: Compare the formation of symptomatic neuromas in patients submitted to digital amputations, with and without nerve conduits (Neurolac^® ), and sensitivity return.

Methods: Prospective, case-control study, including 14 patients with digital amputations (total of 17 fingers) whose conduits were used on the ulnar or radial side, while the contralateral side was used in the same patients as control. The Tinel test, Semmes-Weinstein monofilament, and two-point discrimination tests were evaluated at one week, two weeks, one month, three months, and six months postoperatively.

Results: Using nerve conduits (Neurolac^®) in digital nerve amputation stumps had statistical significance (p = 0.04) in preventing pain due to symptomatic neuroma at the end of six months after digital regularization.

Conclusion: There is a favorable trend towards using conduits as prophylaxis of symptomatic neuroma formation since the nerves in which they were used showed fewer clinical signs of neuroma formation six months after surgery. Level of evidence II, Prospective comparative study.

人工导管在断指残端预防症状性神经瘤的应用。

目的：比较有和没有神经导管（Neurolac®）的指端截肢患者症状性神经瘤的形成及敏感性恢复情况。方法：采用前瞻性病例-对照研究，选取14例（共17指）指端截肢患者，分别在尺侧或桡侧使用导管，对侧使用导管作为对照。分别于术后1周、2周、1个月、3个月和6个月对Tinel试验、Semmes-Weinstein单丝试验和两点鉴别试验进行评估。结果：应用神经导管（Neurolac®）治疗指神经截肢残端术后6个月对预防症状性神经瘤疼痛的效果有统计学意义（p = 0.04）。结论：使用导管作为预防症状性神经瘤形成的良好趋势，因为使用导管的神经在术后6个月出现较少的神经瘤形成的临床体征。证据水平II，前瞻性比较研究。
