目的:探索重建前臂旋后功能的动力肌,并在临床应用中验证其功能效果。方法:采用50例尸体上肢,经灌注后进行解剖、测量,观察尺侧腕屈肌和桡侧腕屈肌大体形态、血液供应及神经支配规律性,并设计临床手术方法,修复8例由于臂丛神经损伤后遗前臂旋后功能障碍,其中使用尺侧腕屈肌3例,桡侧腕屈肌5例。结果:8例平均随访3.6年,前臂总旋转活动度为125°～165°.旋后肌力为Ⅲ~+～Ⅵ级。均能完成日常生活及工作,对屈腕功能无明显影响。结论:尺侧或桡侧腕屈肌移位重建前臂旋后功能。均能达到良好功能恢复。
Objective: To explore the reconstruction of forearm pronation rotational motor muscle, and verify its functional effect in clinical application. Methods: Fifty cases of the upper extremities of cadaver were used to dissect and measure the morphology, blood supply and innervation of the flexor carpi ulnaris and radial wrist flexors. The clinical operation was designed and 8 cases were repaired. Plexus nerve injury posterior arm pronation rotation dysfunction, including the use of the ulnar flexor carpius in 3 cases, 5 cases of radial wrist flexor. Results: The average follow-up of 8 cases was 3.6 years, and the total forearm rotational activity ranged from 125 ° to 165 °. The posterior pronator muscle strength ranged from Ⅲ ~ + to Ⅵ. Can complete daily life and work, no significant effect on wrist function. CONCLUSION: The displacement of the ulnar or flexor carpi ulnaris could reconstruct forearm pronation function. Can achieve good functional recovery.
