Cerebrovascular accidents often produce significant pathology, including upper extremity muscle contractures and deformities that may be painful and aesthetically unappealing and that interfere with activities of daily living and hygiene. Orthopaedic intervention may be required to manage these disabilities. Nonsurgical management includes brachial plexus and phenol nerve blocks, which provide temporary relief of painful contractures and allow for a period of spontaneous neurologic recovery of up to 6 months. Definitive surgical procedures should be avoided during this time. After this period, surgical management can be valuable in releasing muscle spasticity, managing painful contractures, and positioning the deformed extremity in a more functional and aesthetically appealing position. Current surgical management is directed at reducing or eliminating muscle spasticity and joint contractures, with the goal of correcting deformities in shoulder adduction, elbow flexion, forearm pronation, wrist and finger flexion, intrinsic muscle spasticity, thumb-in-palm deformity, wrist extension, and finger extension.
脑血管意外常导致严重病变,包括上肢肌肉挛缩和畸形,这些可能会引起疼痛且外观不佳,还会干扰日常生活活动和卫生状况。可能需要进行骨科干预来处理这些残疾问题。非手术治疗包括臂丛神经阻滞和酚神经阻滞,可暂时缓解疼痛性挛缩,并允许长达6个月的自发神经恢复。在此期间应避免进行确定性手术。这段时间过后,手术治疗在缓解肌肉痉挛、处理疼痛性挛缩以及将畸形肢体放置在更具功能和美观的位置方面可能很有价值。目前的手术治疗旨在减轻或消除肌肉痉挛和关节挛缩,目标是纠正肩部内收、肘部屈曲、前臂旋前、腕部和手指屈曲、固有肌痉挛、掌内拇指畸形、腕部伸展和手指伸展等畸形。
