====== Revision surgery ======

[[Surgery]] for replacement or compensation for a failed [[implant]] or to correct undesirable [[sequelae]] (as scars or scar tissue) of previous surgery.

[[Dural tear]]s (DT) and the consequent cerebral spinal fluid (CSF) leak are not rare in spine surgeries. Cerebrospinal fluid fistula can be troublesome, leading to [[pseudomeningocele,]] cutaneous [[cerebrospinal fluid fistula]], and [[meningitis]]. [[Revision surgery]] is unavoidable in some cases. 
----
[[Morbidity]] and [[revision surgery]] secondary to [[infection]] remains high, even while using [[antibiotic impregnated catheter]]s.

----
A [[cohort]] study showed no significant association between the type of index operation for Degenerative [[Lumbar Spinal Stenosis]]-decompression alone or fusion-and the need for revision surgery or the outcomes of pain, disability, and quality of life among patients after 3 years. Number of revision operations was associated with more pain and worse quality of life
