Influence of depression on patients satisfaction with the outcome of microsurgical "key-hole" vs classical discectomy: prospective matched-cohort study.

Aim: To assess the influence of depression on patients' satisfaction with lumbar discectomy performed by two different surgical techniques.

Methods: A prospective matched-cohort analysis of classical lumbar discectomy following static imaging (n = 45) and microlumbar "key-hole" discectomy after dynamic CT/myelography (n = 55) was performed. The outcome was independently assessed using Prolo economic/activity (E) and functional/pain (F) scale, and depressiveness according to Hamilton rating scale.
