Abstract

Study Design: Multinational survey of spine trauma surgeons. Objectives: To survey a multinational group of spine trauma surgeons and develop an updated consensus definition of posttraumatic kyphosis (PTK), and the most current methods for diagnosis and treatment. Summary of Background Data: PTK remains a potential problematic sequela of thoracolumbar trauma. Although most surgeons have devised their own approaches for detecting and treating this condition, broad agreement in terms of the diagnosis and management of PTK has not been achieved. There is a lack of consensus-based guidelines, as the current literature largely consists of small case series or anecdotal expert opinions. Methods: A survey questionnaire was circulated among 35 multinational spine trauma surgeons. The questionnaire consisted of 29 questions divided into 8 domains: definition, diagnosis, risk factors, symptoms, radiographic evaluation, surgical indications, treatment, and expected outcome. Answers from respondents were compiled and evaluated to generate a consensus. Results: All 35 surgeons completed the survey. Consensus was achieved that PTK represents "a painful kyphotic angulation that can occur anywhere in the posttraumatic spine." Agreement was also reached that asymptomatic PTK can exist, although no true consensus could be reached on the extent of angular deformity that results in PTK. Untreated or maltreated flexion-distraction injuries, or severe burst fractures of the thoracolumbar spine, were felt to be the 2 injuries most likely to produce PTK. Computed tomography, magnetic resonance, and dynamic radiographs were all recommended for evaluation. If surgery is necessary, posteriorly based osteotomies, especially pedicle subtraction osteotomies, have become the principal means of correction. Conclusions: An updated understanding of PTK and its treatment has been achieved. Posterior osteotomies seem to be the most popular means of surgical correction. In the future, multicenter prospective studies are necessary to ascertain, with greater precision, the most appropriate treatment for this condition.
