Abstract
Lumbar spine diseases is most common condition presents with lower backache with radiating pain with or without neurological deficits. Mostly this diseases will have better outcome conservative modalities of treatment but surgery is needed when there is progressive disease even with conservative management. This is a prospective study, includes 20 patients ( 10 single cage and 10 double cage fixation with posterior lumbar interbody fusion). The patients were assessed preoperative and post operatively with prolo score , and radiological tools. The study was carried out for 1 year. At the end of 1 year we found that patients with double cage fixation has better functional and radiological outcome in terms of prolo score assessment and radiological evaluation for cage subsidence respectively as compared to single cage fixation as the later had development of symptoms on contralateral side in few patients and few had cage subsidence at post operative period.
