METHODS: The material consists of a study group with 31 upper limbs of unmatured patients diagnosed with type III and IV radial longitudinal deficiency. The study group was evaluated based on the parameters known from the literature. The difficulties during elongation were classified according to Paley\'s classification.
RESULTS: The study group contained patients with a mean age of 9 years, and the number of boys and girls was comparable. Ulna length significantly increased after elongation compared to the initial bone length. The patient\'s age didn\'t affect the ulna lengthening, and the amount of elongation didn\'t significantly affect the total stabilization period. However, the total stabilization time increased with increasing patient age. Difficulties affected more than half of the cases.
CONCLUSIONS: Ulna elongation in congenital radial deficiency results in significant lengthening of the ulna, and thus the entire forearm, compared to the initial bone length. This technique has a high percentage of difficulty, so its use should be considered after cautious discussion with the parents and patients.
方法:该材料包括一个研究组,该研究组有31个上肢被诊断为III型和IV型桡骨纵向缺陷的未成熟患者。根据文献中已知的参数对研究组进行评估。伸长过程中的困难根据Paley的分类进行分类。
结果:研究组包含平均年龄为9岁的患者,男孩和女孩的数量相当。与初始骨长度相比,伸长后尺骨长度显着增加。病人的年龄对尺骨延长没有影响,伸长量对总稳定期没有显著影响。然而,总稳定时间随着患者年龄的增加而增加。困难影响了一半以上的病例。
结论:先天性桡骨缺损的尺骨伸长导致尺骨显著延长,因此整个前臂,与初始骨骼长度相比。这项技术有很高的难度,因此,应在与父母和患者谨慎讨论后考虑其使用。
