Surgical procedures are performed on the nonfunctional upper extremity following stroke to correct spastic flexion contractures that cause pain or prevent adequate hygiene. In the upper extremity surgical procedures are most commonly performed to improve extension at the wrist, fingers or thumb. If the deformity is primarily due to spasticity rather than fixed myostatic contracture, anesthetic block of the median and/or ulnar nerve preoperatively enables the surgeon to determine that extension will be improved after the appropriate flexor tendons are lengthened. Careful presurgical evaluation of motor sensory function enables the surgeon to predictably select those patients who will benefit from surgery.
对中风后无功能的上肢进行外科手术,以纠正导致疼痛或妨碍充分保持卫生的痉挛性屈曲挛缩。在上肢,外科手术最常进行的目的是改善腕部、手指或拇指的伸展。如果畸形主要是由于痉挛而不是固定的肌静力性挛缩,术前对正中神经和/或尺神经进行麻醉阻滞,可使外科医生确定在适当延长屈肌腱后伸展功能将得到改善。术前对运动感觉功能进行仔细评估,可使外科医生可预测地选择那些将从手术中受益的患者。
