Introduction:

Synovial cysts of the lumbar spine are spread-out substrates generating back and leg pain, radiculopathy and neurological symptoms. Lumbar decompression and total cyst resection is a favorite management bearing a satisfactory outcome. The purpose of this paper is to explain simple sets of measurements used for estimation of spinal functional capability after surgery of such cysts. A single-institution case series of surgical patients was presented and the outcomes were analyzed.

Methods:

To estimate pre- and post-operative/follow-up spinal functional capability patients were asked to fill-in a set of questionnaires consisting of: Visual Analogue Scale (VAS) score and Pain Numeric Rating Scale (PNRS) for pain intensity; Sciatica Bothersomeness Index (SBI) for pain chronicity; Roland-Morris Low Back Pain Disability Questionnaire (RMQ); Oswestry Pain Disability Index (ODI); and The Core Outcome Measures Index for the back (COMI-back) for disability assessment. The spinal functional capability was sorted as excellent, good, fair or poor.

Results:

A decrease in intensity and chronicity of pain, as well as in disability were recorded post-surgery and at follow-ups. The immediate post-operative spinal functional capability was excellently preserved in the majority of patients, while long-term capability was somewhat reduced, but still much better in comparison to preoperative one. The difference between investigated variables was statistically significant (p<0.01).  

Conclusion:

A simple set of measurements is a valuable tool to assess the intensity and chronicity of pain and to estimate short- and long-term spinal functional capability for surgical patients harboring lumbar synovial cysts.
