Swan neck deformity in patients with cerebral palsy can result from hand intrinsic muscle spasticity or overpull of the digital extensors. After accurate identification of the etiology of the deformity, surgical treatment is directed at correcting the underlying muscle imbalance. Intrinsic lengthening can be used to treat intrinsic muscle spasticity, whereas central slip tenotomy is employed when digital extensor overpull is the deforming force. Accurate diagnosis and application of the proper surgical technique are essential when treating swan neck deformity in patients with cerebral palsy.
脑瘫患者的鹅颈畸形可由手部固有肌痉挛或指伸肌过度牵拉引起。在准确识别畸形的病因后，手术治疗旨在纠正潜在的肌肉失衡。固有肌延长术可用于治疗固有肌痉挛，而当指伸肌过度牵拉为致畸形力时，则采用中央束切断术。治疗脑瘫患者的鹅颈畸形时，准确诊断并应用适当的手术技术至关重要。
