三维力学在治疗手外伤后关节僵硬的临床研究

Clinical study of three-dimensional mechanics in the treatment of joint stiffness after hand trauma

目的探索三维力学在治疗手外伤后关节僵硬的临床效果。方法 60例首次发生手外伤术后恢复期患者,随机分为A组、B组和C组,每组20例。A组予以传统运动疗法联合一般动态支具治疗,B组予以传统运动疗法联合三维力学支具治疗,C组予以三维力学治疗方法联合三维力学支具治疗。对三组的临床疗效以及手功能评估情况进行对比分析。结果 C组治疗总有效率为90.00%,高于A组的60.00%和B组的60.00%,差异具有统计学意义(P<0.05)。A组与B组治疗总有效率比较,差异无统计学意义(P>0.05)。A组手指主、被动屈曲度增加值高于B组、A组,B组手指主、被动屈曲度增加值高于A组,差异具有统计学意义(P<0.05)。结论三维力学治疗手外伤后关节僵硬疗效显著,有助于改善骨折愈合不良患者后期功能恢复,适宜临床应用推广。

Objective To investigate the chnical effect of three dimensional mechanics in the treatment of joint stiffness after hand trauma. Methods A total of 60 postoperative recovery patients of first hand injury were randomly divided into group A, group B and group C, with 20 cases in each group. Group A received traditianal sports therapy combined with general dynamic support, group B received traditional sports therapy combined with three-dimensional mechanical support, and group C received three-dimensional mechanical therapy combined with three-dimensional mechanical support. Comparison and analysis were made on clinical efficacy and hand function assessment between two groups. Results Group C had higher total treatment effective rate as 90.00% than 60% and 60.00% in group A and group B, and the difference was statistically significant （P〈0.05）. Group A and group B had no statistically significant difference in total treatment effective rate （P〉0.05）. Group C had higher added value of finger active and passive flexion than group B and group A, and group B had higher added value of finger active and passive flexion than group C. Their difference was statistically significant （P〈0.05）. Conclusion Three-dimensional mechanics provides remarkable efficacy in treating joint stiffness after hand trauma, and helps improve functional recovery of patients with bad fracture healing. It is suitable for clinical application and promotion.
