Surgical enlargement of the intervertebral foramina to relieve NERVE ROOT COMPRESSION.

Discrete spots in taut bands of muscle that produce local and referred pain when muscle bands are compressed.

A surgical procedure that entails removing all (laminectomy) or part (laminotomy) of selected vertebral lamina to relieve pressure on the SPINAL CORD and/or SPINAL NERVE ROOTS. Vertebral lamina is the thin flattened posterior wall of vertebral arch that forms the vertebral foramen through which pass the spinal cord and nerve roots.

Disease involving a spinal nerve root (see SPINAL NERVE ROOTS) which may result from compression related to INTERVERTEBRAL DISK DISPLACEMENT; SPINAL CORD INJURIES; SPINAL DISEASES; and other conditions. Clinical manifestations include radicular pain, weakness, and sensory loss referable to structures innervated by the involved nerve root.

A surgical operation for the relief of pressure in a body compartment or on a body part. (From Dorland, 28th ed)
