UNASSIGNED: This study retrospectively evaluated 7 patients with congenital pseudarthrosis of the tibia who were treated with allograft bypass combined with long-term bracing between 2009 and 2018. The median follow-up was 7.0 years (range 3.8-10.0 years). The medical records and radiographs were reviewed for demographic data, clinical characteristics, outcomes, and complications.
UNASSIGNED: At the time of the last follow-up, all allografts revealed complete consolidation in the patients\' tibiae at both ends. All patients presented no functional restriction of the lower limbs and no amputation or non-union has occurred. Most of the obvious deformities of the tibia diaphysis or ankle joint were corrected. Two complications occurred that required successful revision surgery.
UNASSIGNED: In this series of seven congenital pseudarthrosis of the tibia patients, the allograft bypass technique showed satisfactory midterm results and validated our hypothesis. For congenital pseudarthrosis of the tibia patients of Crawford Type I and II, this procedure combined with long-term bracing, which involves the affected leg only, can delay or possibly prevent fractures, decrease tibial malalignment, and preserve leg length.
UNASSIGNED: level IV.
■这项研究回顾性评估了7例先天性胫骨假关节患者,这些患者在2009年至2018年间接受了同种异体移植旁路术联合长期支撑术治疗。中位随访时间为7.0年(范围3.8-10.0年)。对医疗记录和射线照片进行了人口统计数据审查,临床特征,结果,和并发症。
■在最后一次随访时,所有同种异体移植物均显示患者的胫骨两端完全巩固。所有患者均未出现下肢功能限制,也未发生截肢或不愈合。纠正了胫骨骨干或踝关节的大多数明显畸形。发生两种并发症,需要成功的翻修手术。
■在这一系列7例先天性胫骨假关节患者中,同种异体移植旁路技术显示了令人满意的中期结果,并验证了我们的假设。对于克劳福德I型和II型胫骨患者的先天性假关节,这个过程与长期支撑相结合,只涉及受影响的腿,可以延迟或可能防止骨折,减少胫骨错位,并保持腿的长度。
■四级。
