Introduction:
Spondylolisthesis is a spinal condition characterized by the forward displacement of one vertebra over another, leading to instability and associated symptoms. Surgical intervention is often recommended for patients with symptomatic spondylolisthesis unresponsive to conservative treatment. The objective of this study was to analyze the functional outcomes of surgical management utilizing posterior stabilization and fusion techniques in patients with spondylolisthesis.
Materials And Methods:
This is a prospective study conducted on 30 patients who underwent surgical treatment for spondylolisthesis with posterior trans-pedicular screw fixation with conventional or reduction screws and fusion. Meyerding's grade of listhesis, Japanese Orthopaedic Association (JOA) score, Oswestry disability index (ODI) score and pain scores such as visual analog scale (VAS), numerical rating scale 11 (NRS-11), and pain relief rate were used to analyze the functional outcome.
Results:
Postoperatively, Meyerding's grade of listhesis and the JOA score had improved significantly. The ODI score and pain scores such as VAS, NRS-11, and pain relief rate were better after surgical interventions. There was full motor recovery in 13 patients and 14 patients had full sensory recovery, while six patients had sensory blunting at the time of the time of the last follow-up. Twenty-six (80.7%) patients had clinically successful results and radiological/clinical fusion while four of the patients did not achieve a clinically successful result and radiological/clinical fusion. The average time for bony fusion was 5.58 months with the earliest being 4 months and the latest 12 months. Intraoperatively, one patient had screw slippage and one had a dural tear. Postoperatively, four patients had infection, two patients were presented with deep infection, and the instrumentation had been removed.
Conclusion:
This study demonstrated favorable functional outcomes and improvements in pain, disability, and quality of life measures following surgical intervention.
