Laminoplasty preserving the deep extensor musculature for a pediatric cervicothoracic epidural hematoma case of hemophilia A.

Abstract

Postoperative malalignment after either a laminectomy or a laminoplasty in pediatric cases is a well-known complication. A 5-year-old boy with a history of hemophilia A presented with severe paresis. MRI showed an extensive epidural hematoma extending from C2 to T1. We performed decompression of the spinal cord using laminoplasty, preserving the insertion of the deep extensors. The patient completely recovered from the paresis. Even 7 years after the surgery we could not find any kyphotic deformities. The use of laminoplasty preserving the deep extensor musculature may be crucial for maintaining the postoperative cervical alignment in pediatric patients.
