This study aimed to assess the quality of life of 113 Caucasian patients with intervertebral disc (IVD) degeneration of the lumbosacral (L/S) spine who qualified for microdiscectomy during a 12-month period after surgery. Based on magnetic resonance imaging before the surgery, the degree of radiological advancement of the degenerative changes was determined according to the Pfirrmann grading scale from 1 to 5. To assess pain intensity, the Visual Analog Scale (VAS) was used; the Satisfaction with Life Scale (SWLS) was used to evaluate quality of life; and to assess the degree of ability, the Oswestry Low Back Pain Disability Questionnaire (ODI) was employed. The level of pain, assessed using the VAS, significantly changed in the months following the surgery, with the highest values noted before surgery and the lowest a year after. In turn, the results of the SWLS questionnaire revealed a significant increase in satisfaction with life in the subsequent stages of the study. The conducted correlation analysis revealed significant dependencies in terms of quality of life in regard to pain as well as degree of disability. The level of pain and degree of disability were closely related to the degree of radiological advancement of degenerative changes according to the Pfirrmann grading scale.
