ABSTRACT Presented is a retrospective review of case notes and all available imaging studies in seven patients with acute fractures-dislocations of the cervicothoracic junction. Imaging studies included radiographs (five cases), computed tomography (six cases), and magnetic resonance imaging (seven cases). The study group consisted of five men and two women with mean age at presentation of 43.6 years (range 25-69 years). Four patients had been in road traffic accidents, whereas three patients had had falls. Three patients sustained complete neurologic deficits with no recovery, whereas the remaining four had no abnormal neurology or mild deficit at presentation and were normal at final follow-up. The injury was missed initially in three cases. The commonest injury pattern was traumatic spondylolisthesis of C7 on T1 with multilevel neural arch fractures, resulting in increased anteroposterior canal dimensions (four cases). Bilateral pars fractures of C7 and pure facet dislocation were seen in one case each. Neurologic deficit was related to the degree of anterior displacement of C7 on T1. Fracture-dislocation at the cervicothoracic junction is a rare injury with a variation of injury patterns and neurologic outcome.

    ABSTRACT: Background context Several authors have reported cervical dislocations and fracture-dislocations above, below or through the fused cervical segment after cervical fusion. No previous reports have described fracture/dislocations at the cervicothoracic junction (CTJ) after multilevel anterior cervical spine fusion. Purpose To report CTJ fracture/subluxation after multilevel anterior cervical spine fusion surgery, a technique for surgical management and strategies to prevent this avoidable complication. Study design A case report and review of the literature. Methods A 61-year-old women underwent anterior cervical decompression and fusion (ACDF) from C3 to C7. The patient did well postoperatively until she suffered a CTJ fracture/subluxation 4 months later sustained during a fall. Results The patient underwent posterior and anterior fusion surgery C7–T2. Radiographs 2 years after her reconstruction surgery showed solid fusion from C3 to T2. Conclusions The CTJ area is susceptible to injury because it represents the transition between mobile and relatively immobile portions of the spine, especially when a long lever arm is created by a low cervical fusion. It is difficult to image with plain radiographs, and therefore, injury may be easily overlooked. If overlooked, severe neurological injury can result. Anterior and posterior fusion is often necessary to appropriately stabilize the CTJ after fracture/dislocation.

    ABSTRACT: Purpose of review: A review of the biomechanical and clinical studies of instrumentation at the cervicothoracic junction is presented. A number of studies have presented conflicting recommendations on fixation for instability caused by trauma, tumor and decompression. Focus on the cervicothoracic junction as a challenging area is appropriate because anterior fixation is limited due to the sternum, posterior fixation must successfully avoid the vertebral artery and spinal cord and fixation must be strong enough to withstand the force concentration resulting from the transition from flexible to rigid. Recent findings: Prior studies have suggested that anterior–posterior treatment is necessary for three-column destabilization at the cervicothoracic junction. Recent clinical and in-vitro biomechanical studies have shown that posterior-only treatment may be adequate in the absence of a total vertebrectomy. Notably, the combined use of C7 pedicle screw fixation, monoaxial screws in the thoracic spine, and a dual diameter rod system by posterior-only approach has now been shown to provide sufficient stability in cervicothoracic junction injuries. A review of relevant studies is presented. Summary: Treatment of instability at the cervicothoracic junction may be successfully performed using a posterior approach in most patients. Tumors requiring vertebrectomy may require additional anterior reconstruction.
