Intrapleural Penetration of a Clavicle Fracture: An Indication for Operative Fixation

INTRODUCTION: Clavicle fractures are common injuries treated by orthopedic surgeons, with most injuries managed nonoperatively. Operative fixation of clavicle fractures is indicated in specific clinical scenarios such as open injuries, ipsilateral shoulder trauma, or fractures with associated neurovasculature compromise. Operative fixation is not widely accepted for closed injuries and is typically reserved for instances of failed closed treatment with resultant nonunion or delayed union. Among the complications associated with clavicle fractures, pneumothorax has not been commonly reported. We report a case of a severely displaced clavicle fracture requiring operative repair through plate fixation to achieve union of the fracture as well as resolve the pneumothorax. CASE REPORT: A 22-year-old intoxicated male with no past medical history was admitted to the trauma bay in stable condition after being involved in a motor vehicle accident. On the primary survey, the patient was noted to be tachypneic with decreased breath sounds over his right hemithorax. Radiographic studies of his chest demonstrated a right proximal third clavicle fracture with inferior displacement with associated partial pneumothorax; the patient was also noted to have a right femoral shaft fracture. Neurovascular examinations of his extremities were normal. A chest thoracostomy tube was inserted and placed under suction. Computerized tomography studies later revealed that the fractured clavicle had penetrated the pleura and caused the partial lung collapse. The patient was initially placed in a sling and underwent intramedullary nailing of his femur on the day of presentation. Given the severe displacement of his clavicle fracture into the lung tissue resulting in pneumothorax, there was significant concern for nonunion and lack of resolution of the pneumothorax. 2 days after stabilization of his right femur fracture, the patient underwent open reduction with internal fixation of his right clavicle. Follow-up radiographs showed a healed clavicle fracture and resolved pneumothorax. CONCLUSION: Closed clavicle fractures typically heal uneventfully. Low energy, minimally displaced clavicle fractures can be managed nonoperatively, but high energy, significantly displaced injuries may require operative repair. Specifically, if these injuries result in pneumothorax, physicians shoulder consider operative repair for both treatment of the bony defect as well resulting pneumothorax.
