The long-term results of the key grip procedure (tenodesis of the flexor pollicis longus tendon to the radius, release of the A1 pulley, and percutaneous pin fixation of the interphalangeal joint of the thumb) were evaluated in 10 tetraplegic patients. Seven patients also had tenodesis of the extensor pollicis longus and brevis tendons to prevent flexion at the metacarpophalangeal (MP) joint. Patients were examined an average of 7.4 years after surgery. Progressive flexion of the MP joint gradually occurred, indicating failure of the extensor tenodesis. Excessive bowstringing of the flexor pollicis longus tendon across the MP joint occurred in nine patients. Because of failure of the extensor tenodesis and bowstringing of the flexor tendon, the patients had to progressively extend the wrist further to pinch small objects. Functional testing demonstrated improved hand use in eight patients. Lateral pinch strength was related to wrist extension torque.
对10例四肢瘫痪患者进行了关键握力手术（拇长屈肌腱与桡骨的腱固定术、A1滑车松解术以及拇指指间关节经皮穿针固定术）的长期疗效评估。7例患者还进行了拇长伸肌腱和拇短伸肌腱的腱固定术，以防止掌指关节（MP）屈曲。患者术后平均接受检查7.4年。MP关节逐渐出现进行性屈曲，提示伸肌腱固定术失败。9例患者的拇长屈肌腱在MP关节处出现过度弓弦状畸形。由于伸肌腱固定术失败和屈肌腱弓弦状畸形，患者不得不逐渐进一步伸展手腕以捏取小物体。功能测试显示8例患者手部使用情况有所改善。侧捏力与腕部伸展扭矩相关。
