- A device (usually a long, thin, flexible tube) inserted through the skin into the cerebrospinal fluid space of the lower back; provides a method of draining cerebrospinal fluid.
- LUMBAR KYPHOSIS
- Reverse of the normal curve of the back.
- LUMBAR LORDOSIS
- Angle made by lines drawn from the superior surface of the first and fifth lumbar vertebra.
- LUMBAR MICRODISCECTOMY
- an operation on the lumbar spine performed using a surgical microscope and microsurgical techniques.
- LUMBARIZATION
- Partial or complete formation of a free-moving first sacral segment so that it looks like a lumbar vertebra.
- LUMBOSACRAL CURVE
- A lateral curve with its aspect at or between the fifth lumbar vertebra.
- LUMBOSACRAL JOINT ANGLE
- Angle between the inferior of the fifth lumbar vertebra and the top of the sacrum.
- LUQUE INSTRUMENTATION
- A posterior method of fixation.
- LUQUE ISF
- For posterolateral fusion fixation; a pedicle screw and plate device.

- MAGNETIC RESONANCE ANGIOGRAPHY (MRA)

- MCAFFEE
- Anterior retropharyngeal approach to upper cervical spine; often used for fusion, allowing excision of tumor.
- MEDIAL
- Situated closer to the midline of the body.
- MEDIAN NERVE
- The nerve formed from the brachial plexus that supplies muscles in the anterior forearm and thumb, as well as, sensation of the hand. It may be compressed or trapped at the wrist in carpal tunnel syndrome.
