Use of a novel lag screw by technique approach for repair of a severe lumbar fracture associated with ankylosing spondylitis: A technical case report

Background: The lag screw is a common technique and device used in orthopedic surgery for compressing simple fractures. Here, a lag screw was used to treat a traumatic L5-S1 fracture in a 53-year-old patient with ankylosing spondylitis (AS) resulting in 15 mm of anterior subluxation.

Case description: A 53-year-old patient with AS resulting in 15 mm of anterior subluxation was successfully managed with a lag screw instrumented fusion.

Conclusion: A lag screw successfully stabilized a traumatic L5-S1 lumbar spinal fracture in a patient with AS.
