Assessing Treatment of Floating Lateral Mass (FLM) Fractures of the Subaxial Cervical Spine.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: The purpose of the study was to evaluate differences across surgical approaches (anterior, posterior, or combined anterior-posterior) in terms of outcomes following treatment for floating lateral mass (FLM) fractures. Furthermore, we sought to determine whether operative approach to FLM fracture treatment remains superior to nonoperative treatment in terms of clinical outcomes. BACKGROUND DATA: FLM fractures of the subaxial cervical spine involves separation of the lateral mass from the vertebrae via a disruption of both the lamina and pedicle, resulting in a disconnection of the superior and inferior articular processes. This subset of cervical spine fractures is highly unstable, making proper treatment selection of great importance. METHODS: In this single-center, retrospective study, we identified patients meeting the definition of an FLM fracture. Radiological imaging from the date of injury was reviewed to ensure presence this injury pattern. Treatment course was assessed to determine nonoperative versus operative treatment. Operative treatment was divided into patients who underwent anterior, posterior, or combined anterior-posterior spinal fusion. We then reviewed postoperative complications among each of the subgroups. RESULTS: Forty-five patients were determined to have a FLM fracture over a 10-year span. The nonoperative group had n=25, and evidently, there were no patients that crossed over to surgery due to subluxation of the cervical spine after nonoperative treatment. The operative treatment group had n=20, and consisted of 6 anterior, 12 posterior, and 2 combined approaches. Complications appeared in posterior and combined groups. Two hardware failures were noted in the posterior group, along with two postoperative respiratory complications in the combined group. No complications were observed for the anterior group. CONCLUSIONS: None of the nonoperative patients in this study required further operation or management of their injury, indicating nonoperative treatment as a potentially satisfactory management for appropriately selected FLM fractures.

A retrospective review of the rate of septic knee arthritis after retrograde femoral nailing for traumatic femoral fractures at a single academic institution.

Background: Retrograde intramedullary nailing of the femur is a popular treatment option for femoral shaft fractures. However, this requires accessing the intramedullary canal through the knee, posing a risk of intra-articular infection. The purpose of this study was to examine the rate of intra-articular infection of the knee after retrograde nailing of femoral shaft fractures. Methods: All patients who underwent retrograde intramedullary nailing for femoral shaft fractures between June 2004 and December 2017 at a level 1 trauma center were reviewed. Six months of follow-up or documented fracture union was required. Records were reviewed for documentation of septic arthritis of the ipsilateral knee during the follow-up period. Results: A total of 294 fractures, including 217 closed and 77 open injuries, were included. Eighteen had an associated ipsilateral traumatic arthrotomy; 188 cases had an associated ipsilateral lower extremity fracture. No cases of septic arthritis were identified. Conclusion: There were no cases of septic arthritis in 294 fractures treated with retrograde intramedullary nailing. Retrograde nailing appears safe for risk of postoperative septic arthritis of the knee even in the face of open fractures and traumatic wounds.

Thoracic Spine Fracture After Cardiopulmonary Resuscitation in a Patient with Ankylosing Spondylitis: A Case Report.

CASE: A 32-year-old man with a history of ankylosing spondylitis presented to the emergency department because of sepsis secondary to Fournier's gangrene and subsequently went into cardiac arrest requiring cardiopulmonary resuscitation (CPR). On the twelfth hospital day, a fracture through the T5-T6 intervertebral disk space was incidentally found on a chest, abdominal, and pelvic Computed Tomography (CT) scan. The rounds of CPR were the only traumatic event that the patient underwent before the discovery of the spine fracture. CONCLUSION: A low threshold for advanced imaging should be held to rule out occult spine fractures in patients with ankylosed spines after receiving CPR.
