Low back pain is a highly prevalent condition. About 3 percent of low backache cases need to

be treated operatively . Severe back pain and radiating pain or claudicating which are resistant

to conservative management are usually selected for surgical management.

Due to the increased aging population and the people increasingly getting operated for back

ache, the number of revision surgeries are also rising. Early surgical failures might result from

insufficient decompression and preoperative lumbar instability, or infection with late recurrence

of back or leg problems due to acquired spinal instability or adjacent level degeneration

 Revision surgery is usually required at the index or adjacent levels. Mostly, revision surgery

is required at the index or at adjacent levels. The rates for re operation after decompression

without fusion for LSS are rather consistently reported to be around 8–10% 2 to 4 years

following surgery.

A meta analysis study which reviewed fenestration surgeries showed an average re operation

rate of 7.58% ± 5.29% in 8.28 ± 6.26 years follow up as compared to laminectomy alone

(12.70% ± 7.49%, 6.50 ± 2.12 years follow up). Laminectomy with or without fusion

showed a re operation rate of 11.22% ± 4.25% in 6.00 ± 2.60 years follow up period. The

comparative results of these studies were however not significant .

While recent studies were able to identify particular factors, such as obesity, smoking, or fusion

as decisive for the outcome of lumbar operations, the literature has not demonstrated yet

whether these factors influence re operation.

Revision lumbar decompression and extension of fixation is the gold standard for fixation.Elderly patients requiring revision lumbar spine surgery are a difficult cohort to

treat. Studies have reported poor outcomes when compared to the primary lumbar surgeries.

The goal of this study is to identify the various causes of revision at our institute.
