Long-term Clinical Outcomes of Posterior Spinal Stabilization Using Adeolu's Technique: A Prospective Study from Nigeria.

Background: Due to resource constraints, advanced spinal stabilization methods such as pedicle screws are unavailable at our center. Adeolu's technique, which employs low-cost and readily available vertical struts and spinal process wires, has been used as an adjunct in treating various spinal conditions to achieve rigid spinal constructs. This study evaluates the long-term clinical outcomes of this technique. Methods: Nineteen patients treated with Adeolu's technique were prospectively followed to assess clinical outcomes. Primary outcomes included symptom reduction, absence of adverse events or need for re-intervention, and radiological evidence of stabilization and unrestricted mobilization. Secondary outcomes included back pain intensity, implant-related complications (rotation, migration, back-out, fracture), wound infection, worsening neurological status, and need for implant removal Data were analyzed using SPSS with simple descriptive statistics. Results: The average follow-up period was 4.1 years (Range: 0.1 - 9.0 years). Patients' ages ranged from 20 to 81 years (Mean: 48.5). Indications for surgery included lumbar spondylosis (7, 36.8%), spinal trauma with unstable fractures (4, 21.1%), spinal tumors (4, 21.1%), and Pott's disease (4, 21.1%). All patients achieved satisfactory primary outcomes. Implant rotation was observed in 4 patients (21.1%), and implant migration in 1 patient (5.3%), requiring removal. Superficial surgical site infection occurred in 2 patients (10.5%). No implant fractures, deep infections, or worsening neurological status were noted. Conclusion: Adeolu's technique is effective for a range of spinal pathologies, with favorable long-term clinical outcomes.
