Study DesignThis study reviewed 36 retrospective patients who underwent surgeries for rare cervico-thoracic junctional problems.ObjectivesThe authors review cervico-thoracic junctional disorders and study diagnostic methods, surgical approaches, surgical outcomes, and associated complications.Summary Of Background DataThe literature is sparse on cervico-thoracic junctional problems. This paper is the largest series to date on this subject.MethodsThirty-six patients who underwent surgeries for spinal problems at the cervico-thoracic region (C7-T3) were reviewed. These included 18 patients with trauma, 15 patients with tumors, 2 patients with herniated discs, and one patient with postlaminectomy instability. There were 20 males and 16 females. The age ranged from 17 to 83 years with a mean of 43.5 years. Surgically, 21 patients had only posterior procedures, that included 12 wiring, 5 Luque rodding, 1 plate-screw fixation for postlaminectomy instability, 1 transpedicular biopsy, 1 foraminotomy for herniated C7-T1 disc, and 1 costotransversectomy for T2-T3 herniated disc. Neurologically, the majority of traumatic patients presented with neurologic deficits (10 complete and 4 incomplete, and 1 root injuries), and nontraumatic disorders were associated with 10 incomplete cord syndromes and 5 root dysfunctions.ResultsFollow-up average was 38 months based on 33 of 36 patients. There were three postoperative deaths (two sternotomies, one anterior C7 corpectomy). Neurologically, patients with complete cord injuries remained complete, whereas patients with incomplete or root deficits improved significantly. Complications included C6-C7 subluxation after C7-T2 fusion, pseudomeningocele, vocal cord paralysis, dysphagia, and Horner's syndrome. Other complications included wound infections, urinary tract infections, decubiti, deep vein thrombosis, pneumonia, and tumor recurrence.ConclusionsIn treating patients with cervico-thoracic problems, one should do careful clinical and radiologic survey to avoid missed or delayed diagnoses, and the surgeon must be thoroughly familiar with anterior and posterior landmarks and associated vital structures and remember that the cervico-thoracic junction is an area of potential instability particularly after trauma or laminectomy. Complications of surgery at the cervico-thoracic junction are frequent, and meticulous surgical techniques and postoperative care are important in the prevention of these complications.
