Precision Repair of Bilateral Pars Defect Using Robotic Assistance and r-Bmp in a National-Level Adolescent Athlete: A Case Report.

CASE: A 14-year-old national-level badminton player presented with bilateral L5 pars interarticularis defects with pseudoarthrosis, unresponsive to conservative management. Computed tomography confirmed bilateral pars defect with sclerosed margins without spondylolisthesis or canal compromise. The patient underwent robotic-assisted minimally invasive pars repair augmented with recombinant human bone morphogenetic protein. Postoperatively, he reported minimal pain, resumed full athletic training by 12 weeks, and remained symptom-free at 1-year follow-up.

CONCLUSION

Robotic-assisted direct pars repair with biologic augmentation offers precise screw placement, muscle preservation, and accelerated recovery in adolescent spondylolysis, representing a valuable option for patients failing conservative therapy and seeking rapid return to sport.
