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

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.
