Introduction: Lumbar degenerative disease is a common health problem all over the world and the need for revision surgery is still high with variable results. The aim of the work: Is to evaluate the clinical and radiologic outcome in cases of redo surgery for lumbar degenerative pathology and to specify which pathology is responding well to revision surgery.
Patients and methods: Forty eight patients were operated upon for revision of previous failed back surgery in Zagazig University Hospitals from August 2014 to April 2017. Selection of patients for revision surgery depends on confirmed radiological and clinical compression or instability. All patients were operated and followed for at least 6 months after surgery. VAS score was used as a tool for evaluation of back and leg pain.
Results: There were 48 patients; with a mean age of 46.7 years (range 22-78).There were 29 males and 19 females. The dominant symptoms were unilateral sciatica in 30, bilateral in 11, low back pain in 23 patients .Neurogenic claudication was present in 4 cases. Type of surgery was redo discectomy in 31 cases, revision decompression for spinal canal stenosis in 4 cases, and posterior lumbar interbody fusion in 13 cases, with success rate of 96.8%, 75% and 84.6% respectively regarding improvement after surgery.
Conclusion: Revision surgery of lumbar degenerative diseases gives excellent results provided that the patients are properly selected.
