This study aimed to assess the results of femoral lengthening using an external fixator and then plating.
This prospective case series study enrolled 11 patients who underwent femoral lengthening and then plating (LATP) between January 2019 and April 2023. The average age of patients was 14.45 ± 7.54 years. One patient with a femur was lengthened and plated, and one tibia was lengthened over a nail simultaneously. The average femoral lengthening was 8.41 ± 1.35 cm.
The femoral healing result was excellent in seven femurs and good in four femurs; the functional outcome was excellent in five patients and good in six patients. Pin-track infection occurred in all patients. A limited range of motion of knee flexion occurred in eight patients. Femoral varus and procurvatum deviation occurred during distraction in four and two patients. Femoral LATP was considered an attractive alternative to intramedullary lengthening nails in a low-income country.
Our research suggests that femoral LATP was an effective method. However, the most common complications were pin-site infection and extensive knee contracture. Further research should be done with a larger sample size and longer follow-up time.
Level IV-prospective observational case series study.
本研究旨在评估使用外固定器然后进行钢板固定的股骨延长术的结果。
本前瞻性病例系列研究纳入了2019年1月至2023年4月期间接受股骨延长术然后进行钢板固定（LATP）的11例患者。患者的平均年龄为14.45±7.54岁。1例患者的股骨进行了延长和钢板固定，1例患者的胫骨在髓内钉上同时进行了延长。平均股骨延长长度为8.41±1.35厘米。
7个股骨的愈合结果为优，4个股骨为良；5例患者的功能结果为优，6例为良。所有患者均发生了针道感染。8例患者出现了膝关节屈曲活动范围受限。4例和2例患者在牵张过程中出现了股骨内翻和前凸畸形。在低收入国家，股骨LATP被认为是髓内延长钉的一种有吸引力的替代方法。
我们的研究表明，股骨LATP是一种有效的方法。然而，最常见的并发症是针道感染和严重的膝关节挛缩。应进行更大样本量和更长随访时间的进一步研究。
IV级——前瞻性观察性病例系列研究。
