Do All Fractures in the Ankylotic Spine Really Require Surgical Intervention?

TL;DR

Some spine fractures in patients with a rigid spine can heal without surgery, avoiding risks and complications.

Contribution

Identifies a subset of spine fractures in DISH patients that can be safely treated non-operatively.

Findings

22 extension fractures in 21 DISH patients were treated non-operatively with full healing.

No neurological complications or need for later surgery occurred in the study group.

Abstract

Background: Patients with ankylotic spines suffering from vertebral column fractures are frequently operated on to maintain spinal stability and prevent secondary displacement and nerve damage. The aim of this study was to identify a subset of patients that may be treated non-operatively, thus avoiding operative complications in this group of patients. Methods: Extension-type injuries in patients with DISH (diffuse idiopathic skeletal hyperostosis) not involving the posterior elements of the spine comprised the study group. Results: Twenty two extension fractures occurred in 21 patients with DISH in SZMC (Shaare Zedek Medical Cente) between 2014–2025. All patients were treated non-operatively. Patients were allowed free mobilization, and no orthosis was used. The only limitation was keeping the bed inclined to 20–30 degrees to prevent extension at the fracture site. All fractures healed uneventfully, and no patient required late surgical intervention, and no neurological complications were noted. Conclusions: Patients with DISH who sustain extension-type injuries of the thoracolumbar spine, with no involvement of the posterior elements, may be treated non-operatively, with good results.
