Objective
Cervical radiculopathy due to lateral compressive disease has traditionally been treated by anterior discectomy with interboby fusion. However, bone fusion with elimination of a motion segment may lead to acceleration of degenerative changes at adjacent levels. Although the posterior approach preserves the motion segment, decompression of the nerve root is indirect if "hard disc prolaps" is the main cause. In this study, we present microsurgical anterior foraminotomy for the treatment of radiculopathy with preservation of the segmental mobility.
Methods
Twelve patients - 5 men and 7 women with an average age of 48 years - with unilateral radiculopathy underwent anterior foraminotomy via a small keyhole transuncal approach. The base of uncinate process was directly drilled in the trajectory to the intervertebral foramen without destroying the disc tissue. The vertebral artery between the transverse process was not exposed.
Results
All patients experienced complete relief of radiating pain. A cervical collar was not used. Mean follow-up time was 9 months. The motion of the operated segment was preserved in each patient. No instability of the cervical spine was seen.
Conclusions
The microsurgical anterior foraminotomy via a small keyhole transuncal approach is safe, minimally invasive, and represents an effective method to treat unilateral cervical radiculopathy caused by disc prolaps and/or uncovertebral osteophytes. Additionally, the segment mobility is preserved and prevents the acceleration of degenerative changes at adjacent levels.
