BACKGROUND AND PURPOSE We report results and complications of gradual bone lengthening for post-traumatic lower-limb length discrepancy (LLD) with Precice intramedullary lengthening nails in 34 adults. PATIENTS AND METHODS Inclusion criteria were lower-limb lengthening using the Precice nail, posttraumatic etiology, age older than 18 years, and minimum follow-up of 12 months after implantation. 34 patients met the inclusion criteria. Radiological and clinical outcome data were collected. RESULTS Precice lengthening was performed in the femur in 28 patients (21 antegrade, 7 retrograde) and in the tibia in 6. Mean patient age at time of surgery was 32 years (18-72). Mean preoperative LLD was 31 mm (20-71). Acute correction of axial or rotational malalignment was performed in 11 segments. At final follow-up (mean 2 years [1.1-3.6]), 33 of 34 nails had been removed. All lengthening sites were healed, and all patients mobilized with full weight-bearing. 14 adverse events occurred in 11 patients and were categorized as problems (n = 5), obstacles (n = 3), and complications (n = 6). Unplanned surgery was necessary in 7 patients, 3 of whom did not complete treatment with Precice. INTERPRETATION Correction of posttraumatic LLD with or without axial malalignment using Precice intramedullary lengthening nails is associated with a low number of complications and good functional outcome. However, one-fifth of patients in this series needed further unplanned surgery for revision of obstacles or complications.

使用 Precice 髓内加长钉矫正创伤后下肢畸形:对 34 名成人的回顾,平均随访 2 年。

背景和目的 我们报告了 34 名成人使用 Precice 髓内延长髓内钉逐渐延长骨质以治疗创伤后下肢长度差异 (LLD) 的结果和并发症。患者和方法 纳入标准是使用 Precice 钉延长下肢、创伤后病因、年龄超过 18 岁以及植入后至少随访 12 个月。34 名患者符合纳入标准。收集放射学和临床结果数据。结果 28 名患者(21 名顺行,7 名逆行)和 6 名患者在胫骨进行了精确延长。手术时患者的平均年龄为 32 岁 (18-72)。平均术前 LLD 为 31 mm (20-71)。在 11 个节段中进行了轴向或旋转错位的急性矫正。在最终随访时(平均 2 年 [1.1-3.6]),34 个钉子中的 33 个已被移除。所有延长部位均已愈合,所有患者均能完全负重活动。11 名患者发生了 14 起不良事件,分为问题 (n = 5)、障碍 (n = 3) 和并发症 (n = 6)。7 名患者需要进行计划外手术,其中 3 名患者未完成 Precice 治疗。解释 使用 Precice 髓内加长髓内钉矫正伴或不伴轴向错位的创伤后 LLD 与较少的并发症和良好的功能结果相关。然而,该系列中五分之一的患者需要进一步的计划外手术来修复障碍或并发症。11 名患者发生了 14 起不良事件,分为问题 (n = 5)、障碍 (n = 3) 和并发症 (n = 6)。7 名患者需要进行计划外手术,其中 3 名患者未完成 Precice 治疗。解释 使用 Precice 髓内加长髓内钉矫正伴或不伴轴向错位的创伤后 LLD 与较少的并发症和良好的功能结果相关。然而,该系列中五分之一的患者需要进一步的计划外手术来修复障碍或并发症。11 名患者发生了 14 起不良事件,分为问题 (n = 5)、障碍 (n = 3) 和并发症 (n = 6)。7 名患者需要进行计划外手术,其中 3 名患者未完成 Precice 治疗。解释 使用 Precice 髓内加长髓内钉矫正伴或不伴轴向错位的创伤后 LLD 与较少的并发症和良好的功能结果相关。然而,该系列中五分之一的患者需要进一步的计划外手术来修复障碍或并发症。解释 使用 Precice 髓内加长髓内钉矫正伴或不伴轴向错位的创伤后 LLD 与较少的并发症和良好的功能结果相关。然而,该系列中五分之一的患者需要进一步的计划外手术来修复障碍或并发症。解释 使用 Precice 髓内加长髓内钉矫正伴或不伴轴向错位的创伤后 LLD 与较少的并发症和良好的功能结果相关。然而,该系列中五分之一的患者需要进一步的计划外手术来修复障碍或并发症。
