Abstract:
CT was performed in 51 patients at and caudal to the level of lumbar myelographic block due to disc herniation with or without lumbar canal stenosis. The causes of complete or almost complete myelographic block included disc herniation (27 patients)disc herniation with spinal stenosis (12 Patients), spinal canal stenosis (11 patients) and posterior osteophytes (1 patient). CT helped in detecting the non-visualised vertebral levels, demonstrated a surgically treatable lesion below the level of myelographic block and provided information for preoperative planning.

Muscles of the Vertebral Column
Superficial Layer:
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...

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...
