Functional Prognosis Factors of Persistent Lower Back Pain After Surgery

Persistent lumbosciatic after surgery is common, secondary to two essentially etiopathogenic mechanisms. They are also sources of physical disability among other things and the results on functional prognosis factors are contradictory. Objective: Our objective was to determine the functional prognosis factors of patients with persistent lumbosciatic after surgery. Methods: We conducted a single-center, cross-sectional study lasting 6 months, including the patients with lumbosciatic persisting beyond 4 weeks, after surgery. Patients with severe cognitive impairment were excluded. After identifying the initial impairments, the patients were invited for an assessment of functional capacities (Oswestry Disability Index) and quality of life (SF12). Results: 46 patient files were retained. The average age of the patients was 49.39±14.53 years. The sex ratio was 1 and more than ¾ of the patients were married (78.26%). Forty-three percent (43.48%) of patients were technicians. More than half of our patients consulted within less than 3 months (53.13%). Isolated discectomy (62.12%) was the main surgical procedure performed. After rehabilitation treatment, the average ODI score was 37%±18%. The functional prognostic factors are marital status, static spinal disorders, pain, paralysis in lower limb. They were associated with “sexual life, sleep, postural, intensity of pain, walking, physical dimensions”. Discussion and conclusion: Our results confirm certain functional prognostic factors for persistent lumbosciatic, after surgery ostoperative, in a context of late rehabilitation care. The most impaired functional areas are loading handling, walking, postural, pain intensity and sexual life.
