A new management strategy in reopening laminectomies for cases with spinal canal stenosis

Background While a laminectomy is often mandated for spinal canal stenosis, foraminal stenosis may account for pain and functional limitations instead of central canal issues. Targeted treatment directed at this specific region may enhance patient outcomes. Methods Retrospective observational study of a total of 30 patients with previous decompression laminectomies for lumbar spinal canal stenosis were operated upon for foraminotomies from November 2012 to November 2018. The surgeries were clinically done, and EMG-confirmed nerve root compressions were treated with exact decompression techniques according to the anatomy and pathology in each case. Additionally, a systematic review followed PRISMA guidelines was conducted, utilizing Scopus and PubMed databases to identify studies on reoperation rates after decompression with or without fusion in lumbar spinal stenosis. Results The results were fearsome post-operatively, trying significant improvement in pain, functional status, and walking distance. Pain reduction was achieved in 80% of patients by an increase in the Carnovsky rating scale with evidence of improved pain reduction and walking endurance; this points to minimal resulting complications of one complete case of foot drop and three infective cases managed conservatively. It was shown in the systematic review that fusion surgeries lowered the rates of reoperations at the index level but increased those for adjacent segment reoperations, while decompression alone had higher index-level reoperation rates due to recurrent stenosis. Conclusion Most of the emphasis on foraminal stenosis, rather than traditional laminectomies, significantly reduces postoperative pain and improves functional outcomes. This strategy brings a promising alternative to the management of recurrent symptoms in patients with lumbar spinal canal stenosis.
