In the cervical spine, deep paraspinal muscles (DPMs) function to preserve spinal stability and mobility. However, the relationship between DPMs and bone union after cervical fusion surgery has not yet been investigated. The objective of this study is to evaluate the relationship between the cross-sectional area (CSA) of DPMs and bone union after cage alone anterior cervical decompression and fusion (ACDF). ⋯ The extensor CSAs were related to fusion rate and timing. In particular, as the extensor CSAs increased, fusion timing decreased.

Prompt decompression in clinically significant cervical stenosis is important in the prevention of neurological sequelae. Disparities exist along the continuum on spine care, with black patients receiving less surgery and experiencing worse postoperative outcomes. The aim of this study was to assess whether black race was an independent predictor for a prolonged time to diagnosis and treatment. ⋯ Our study demonstrates that race is an independent risk factor for a temporal delay in diagnosis and treatment of symptomatic cervical stenosis.

The aim of our study was to determine the presence of heterotopic ossifications (HO) in a series of patients with cervical disk arthroplasty treated with different type of prosthesis, as well as to analyze the most suitable systems for diagnosis. ⋯ Our results showed that, although cervical disks provide optimal mid-term results, the incidence of HO seems to increase with time. Long term studies, with a larger sample size should be conducted to evaluate the appearance of HO and cervical motion after total disk replacement.

Type II Odontoid Fracture with Atlantoaxial Dislocation Presenting as Symptomatic Seizures: A Case Report.
To report symptomatic seizures of a patient with an old type II odontoid fracture with atlantoaxial dislocation. The type II odontoid fracture is a dangerous disease and presents as neurological deficits. Because of the compression of upper cervical cord, without timely diagnosis and treatment, a type II odontoid fracture may result in sudden death. Although it has been shown that epileptic seizures may lead to type II odontoid fracture, there is no report of symptomatic seizures in patients with odontoid fracture. ⋯ Old type II odontoid fracture might present as symptomatic seizures in addition to other neurological deficits. Posterior atlantoaxial screw-plate fixation and fusion is an effective treatment for old type II odontoid fracture.
