ABSTRACT
OBJECTIVE:
To compare the radiological and functional outcomes and complications of adult spinal deformity patients who underwent a pedicle subtraction osteotomy (PSO) below L2 but categorized according to their construct where either 2-rod or multiple-rod construct is applied.METHODS:
Sixty-seven patients met the inclusion criteria, and were categorized into 3 groups 2 rods (2R), multiple rods around the PSO (MRP), multiple rods around the PSO and lumbosacral junction (MRL). Demographic data, operative parameters, spinopelvic parameters, functional outcomes, and complications were collected.RESULTS:
Health-related quality of life scores showed a better outcome at 6 months and last follow-up visits in the MRP and MRL groups which were noted on different domains of Scoliosis Research Society-22 questionnaire, 36-item Short Form Health Surve, and Oswestry Disability Index scores (p < 0.05). The 3 groups showed similar rates of rod-related complications with no significant difference (p = 0.95). And inside each group, distribution of complications between pseudarthrosis with revision and rod fracture without revision was also similar (p = 0.99).CONCLUSION:
The use of multiple rods across the PSO did not show a better outcome when compared to single rods in terms of incidence and types of mechanical complications. However, better postoperative coronal alignment and health-related quality of life scores in the multiple rods group could be seen demonstrating an improved functional outcome.
