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 tears (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 catheters.
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 1).
