Summary
Degenerative lumbar curves with atypical presentations may worsen with surgery alone. Augmenting decompression with Harrington instrumentation and fusion can address persistent pain and instability in these cases.
Area of Science:
- Orthopedics
- Neurosurgery
- Spine Surgery
Background:
- Degenerative lumbar curves often present as stable deformities with spondylotic compression.
- Previous research has primarily focused on these typical presentations.
Observation:
- A review of 14 cases revealed that half had atypical radiographic presentations of short reciprocating lumbar curves.
- These cases were associated with asymmetric intervertebral osteochondrosis, lacking typical spondylotic ridging and buttressing.
Findings:
- Major decompressive surgery alone in these atypical cases may increase instability and hasten spinal collapse.
- While decompression relieved radicular pain, several patients experienced persistent mechanical low-back pain.
Implications:
- Consider augmenting decompressive procedures with Harrington instrumentation and fusion for atypical degenerative lumbar curves.
- This approach may help manage postoperative instability and persistent mechanical back pain in collapsing lumbar spines.
