Cervical myelopathy secondary to omovertebral bone in the pediatric patient with Sprengel deformity.

Sprengel deformity is a congenital anomaly arising mainly in the shoulder girdle, associated with elevation of dysplastic scapula. skeletal anomalies, mainly Klippel-Feil syndrome, hemivertebrae, and omovertebral bone may be present along Sprengel anomaly. The omovertebral bone is an abnormal bone that originates from the superomedial edge of the scapula with different insertion points along the posterior cervical spine, seen in about third of the patients with Sprengel anomaly. While cosmetic to functional impairment is a common presentation to the omovertebral bone, cervical myelopathy is a rare presentation. Here, we described our experience, management and follow up of 13-year-old boy presented with cervical myelopathy secondary to the omovertebral bone.
