Spasticity affects more than 80% of patients with spinal cord injury. Neural mechanisms and musculotendinous alterations lead to typical upper extremity features including shoulder adduction/internal rotation, forearm pronation, and elbow, wrist, and finger flexion. Long-standing spasticity may lead to soft tissue and joint contractures and further impairment of upper extremity function. Surgical management involves tendon lengthening, release, and transfer, as well as selective neurotomy, in an effort to reduce spastic muscle hypertonicity, restore balance, prevent further contracture, and improve posture and function. This article summarizes surgical strategies to improve function of the upper extremity in patients with tetraplegia.
