Abstract:
The unusual association of an omovertebral bone with Sprengel deformity and Klippel-Feil syndrome is a complex bone anomaly of unknown incidence and etiology. However, several cases of this rare disease pattern have been reported in the literature. In this paper, the authors present the case of a 34-year-old woman with a 5-month history of progressive gait ataxia and intermittent urinary incontinence, which was found to be caused by aberrant bone growth into the spinal canal from an omovertebral bone that extended from the left scapula pressing into the C-6 vertebral arch and subsequently causing cervical myelopathy. The patient underwent isolated resection of the omovertebral bone and decompression of the spinal canal, and her functional and neurological outcome was favorable.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
