Efficacy and Safety of Lumbar Arthroplasty in Degenerative Disc Disease

Abstract

Objective: The objective of this longitudinal retrospective study is to assess the efficacy and safety of total lumbar disc replacement in patients with degenerative discopathy (L3-L4, L4-L5, L5-S1). Methods: One hundred and forty-three patients with low back pain, with or without radiculopathy, who met the radiographic criteria underwent anterior arthroplasty between 2000 and 2016. The Oswestry disability index (ODI), the visual analog scale (VAS), patient satisfaction, success criteria, disc height, and range of motion of the operated segment were evaluated preoperatively and at 3, 6, 12, and 24 months following surgery. Results: There were 50 men and 93 women, with an average age of 39.5 years, 13 patients (9%) with previous discectomy. The arthroplasty was performed at level L5-S1 in 97 patients (67.8%), at level L4-L5 in 45 patients (31.5%), and at level L3-L4 in 1 patient. Between the preoperative period and 24 months following surgery, the ODI decreased by 53.86%, the VAS for low back pain decreased by 63.83%, and low back pain with radiculopathy decreased by 60.20%, all statistically significant (p ≤ 0.5). Eighty-two percent of the patients were completely satisfied and 18% were satisfied. There was an average increase in disc height of 12 mm (p <0.001). The range of motion of the affected segment increased by 4° to 7° after surgery (p <0.004). Conclusions: Lumbar arthroplasty of a segment is recommended as an effective treatment for patients with degenerative disc disease with low back pain with or without a root component who meet the inclusion criteria. Level of Evidence III, Systematic review b of Level III studies.Keywords: Lumbar region; Arthrodesis; Arthroplasty. 60,20%. Cambio estadísticamente significativo (p ≤ 0,5). El 82% completamente satisfecho y satisfecho 18%. La altura discal aumentó 12 mm promedio (p <0,001). El movimiento del segmento afectado aumentó 4° a 7° después de la cirugía (p <0,004). Conclusión: La artroplastia lumbar de un segmento se recomienda como tratamiento eficaz para pacientes con enfermedad degenerativa discal que cumplen con los criterios de inclusión y lumbalgia sola o con componente radicular. RESUMO Objetivo: Para avaliar a eficácia e a segurança da reposição do disco lombar total em pacientes com discopatia degenerativa (L3-L4, L4-L5, L5-S1
