Lytic spondylolisthesis above the lumbosacral level

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Lytic spondylolisthesis, particularly above the lumbosacral junction, is associated with increased neurological signs and spinal stenosis.
• Forward slip can progress in adulthood, necessitating surgical intervention for severe symptoms.

Purpose of the Study:

• To evaluate surgical outcomes for lytic spondylolisthesis occurring above the fifth lumbar vertebra (L5).
• To compare the efficacy of fusion alone versus fusion with decompression in patients with and without neurological deficits.

Main Methods:

• Retrospective study of 27 patients with symptomatic lytic spondylolisthesis above L5 requiring surgery.
• Patients were grouped based on the presence or absence of preoperative neurologic signs.
• Surgical outcomes were assessed following fusion procedures, with or without decompression.

Main Results:

• Patients without neurological signs achieved satisfactory results with fusion alone.
• Patients with preoperative neurological deficits had less favorable outcomes with fusion alone.
• The necessity of spinal decompression in patients with neurological compromise was highlighted.

Conclusions:

• Surgical management of lytic spondylolisthesis above L5 should be tailored to the patient's neurological status.
• Fusion alone is effective for neurologically intact patients, whereas decompression is crucial for those with neurological deficits to improve surgical outcomes.
