Postoperative epidural hematoma (EDH) usually present with neurological deficit. Massive EDH presenting with only severe pain without neurological deficit are rare. Atypical presentations of postoperative EDHs may lead to delayed diagnosis and treatment. We present three such cases after posterior cervical spine surgery. Three patients presented with severe neck pain and spasms without motor deficits several days after posterior cervical decompressive procedures. Imaging studies identified compressive EDHs at the surgical site with severe compression of the spinal cord. All were treated with emergent decompression, with resulting improvement of symptoms and pain relief without further neurological sequelae. In conclusion, postoperative EDHs after posterior cervical spine surgery may result in minimal neurological deficit. Our report reminds surgeons to keep this possibility in mind when patients complain of unusually severe neck pain and spasms after posterior cervical spine surgery.

Methods: Patients presenting with a spine fracture were diagnosed with AS or DISH at a single tertiary care center between 2010 and 2019. We excluded those who lacked cross-sectional imaging or fractures occurring at spinal segments affected by ankylosis, as well as polytraumatized patients. Patient demographics, injury mechanism, fracture level, neurologic status, treatment, and 1-year mortality were recorded. Computed tomography imaging was reviewed by two independent readers and graded according to the indicated AO Spine Injury Classification System. Differences in fracture severity, treatment method, and mortality were examined using Student t -tests, chi-square tests, and two-proportion Z-tests with significance set to p <0.05. Results: We identified 167 patients with spine fracture diagnosed with AS or DISH. Patients with AS had more severe fractures and more commonly had surgery than patients with DISH (p <0.001). Despite these differences, 1-year mortality did not significantly differ between AS and DISH patients (p =0.14). Conclusions Although patients with AS suffered more severe fractures compared to DISH and more frequently underwent surgery for these injuries, outcomes and 1-year mortality did not differ significantly between the two groups. For patients with ASDs and fractures, outcomes appear similar regardless of treatment modality. Consequently, there may be an opportunity for critical reappraisal of operative indications in ASD and a larger role for nonoperative management in these challenging patients.
