摘要
Descriptive retrospective cohort of 52 pediatric patients with mucopolysaccharidosis (MPS) and spinal cord disease and surgical outcomes in a reference hospital.To describe clinical manifestations and surgical management and outcomes of spinal lesions.All medical records of 52 patients with mucopolysaccharidosis (I, II, III, IV, and VI) diagnosed between 1992 and 2011 were identified and followed at a single spine center of a pediatric hospital. Demographic, clinical manifestations, spinal cord lesions, and surgical management were the focus of the descriptive report.A total of 52 patients (32 males and 20 females), mean age at diagnosis of 8 ± 4 years (range 1–19), and with a mean follow-up of 11 ± 8 years were identified. Forty-three had cervical disease (the most frequent affection found was odontoid hypoplasia followed by atlantoaxial instability) and 14 patients had thoracolumbar kyphosis. Twenty-one patients presented neurologic compromise before surgery (quadriparesis as the most frequent manifestation), with the progression of neurologic impairment being the most common surgical indication. Surgery was performed in 38 patients (25 cervical and 13 thoracolumbar). Of the 21 patients with preoperative neurologic deficit, 6 patients showed neurologic improvement. The most common surgical complication found was proximal junctional kyphosis.This is the largest series published of mucopolysaccharidosis pediatric patients with a surgically treated spinal condition. We recommend early spinal cord decompression in mucopolysaccharidosis spine pathology to prevent or potentially reverse neurologic impairment.Level IV.
