The article analyzes the relationship between the intensity of leg pain and the duration of chronic pain syndrome in patients before and after surgical treatment of lumbar spinal stenosis (LSS). The study involved 70 patients who underwent endoscopic unilateral laminotomy for bilateral decompression. Pain intensity was assessed using the Visual Analog Scale (VAS), and quality of life was evaluated with the Oswestry Disability Index (ODI) at various time points: preoperatively, and at 1, 6, and 12 months postoperatively.
The results demonstrated that patients with prolonged chronic pain had higher postoperative pain intensity and less pronounced improvement in quality of life compared to those with shorter pain durations. A weak negative correlation was identified between pain duration and its intensity, suggesting that chronic pain mechanisms may differ depending on its length. Patients with shorter pain durations achieved better outcomes, including significant reductions in ODI scores, while those with longer pain durations showed slower recovery and less improvement even six months postoperatively.
The study highlights the importance of early intervention and a personalized approach to the treatment and rehabilitation of patients with varying durations of chronic pain. Incorporating minimally invasive techniques, such as endoscopic laminotomy, showed promising clinical results, including reduced postoperative pain and disability. However, the findings emphasize the need for tailored rehabilitation programs for patients with a longer history of pain to enhance long-term outcomes.
Future research should focus on expanding the sample size and exploring additional factors influencing postoperative recovery, including psychological aspects and comorbid conditions. These findings underline the clinical importance of addressing chronic pain comprehensively to optimize the management and improve the quality of life for patients undergoing surgical treatment for lumbar spinal stenosis.
