将后三角肌转移到三头肌止点以进行肘部伸展，可以改善 C5 和 C6 水平四肢瘫痪患者的功能。我们使用胫骨前肌腱作为移植物改进了手术技术。通过术中电刺激确定后三角肌的长度-张力特征和可用幅度。三角肌后束的偏移量为 7.31 厘米，标准差为 1.23 厘米。 术后肘部伸展力的平均扭矩测量值为 36.4 kg·cm，标准差为 15 kg·cm。所有患者的最大力量都在90°之间。和120度。肘部屈曲。后三角肌的长度-张力曲线显示了大范围的有效力量，有助于确定后三角肌的最佳张力以及手术时正确的肩部和肘部位置。 10名患者的临床结果非常好。
Transfer of the posterior deltoid muscle to the triceps insertion for elbow extension provides improved function in patients with C5 and C6 level tetraplegia. We have modified the surgical technique using the tibialis anterior tendon as a graft. The length-tension characteristics and available amplitude of the posterior deltoid muscle were determined with intraoperative electrical stimulation. The excursion of the posterior deltoid muscle was 7.31 cm with a standard deviation of 1.23 cm. Postoperative mean torque measurements of elbow extension power were 36.4 kg cm with a standard deviation of 15 kg cm. All patients had maximal strength between 90.degree. and 120.degree. of elbow flexion. Length-tension curves for the posterior deltoid muscle showed a large range of effective strength and helped confirm optimum tension of the posterior deltoid muscle and proper shoulder and elbow positions at surgery. Clinical results in 10 patients were excellent.
