Introduction: Coronal shear fractures of the distal humerus represent an uncommon lesion and could be burdened by high complications. This complex lesion requires an accurate reduction and surgical fixation for a better outcome. Different techniques have been described, however no standard protocol have been proposed. Purpose of this retrospective study, is to evaluate the clinical and radiological outcome with posterior cannulated self-tapping headless screws followed by an early-active-motion protocol and to outline the surgical tips and tricks for different fracture patterns. Materials and methods: From 2013 to 2019, a consecutive series of 24 patients with coronal shear fracture undergoing ORIF were included in the study. Fractures were classified according to Dubberley’s classification. Cannulated self-tapping headless screws were used to fix the fragments. When necessary, additional cannulated half-threaded screws on the lateral edge of the humerus were used, as well as bone chips and fibrin sealant on severe comminution. All patients underwent an assisted early-active-motion rehabilitation protocol. Mean follow-up was 30 months; patients underwent standard X-rays and clinical outcome assessment with range of motion, Broberg and Morrey score and MEPI score. Results: Surgical fixation with headless screw guaranteed complete healing of all shear fractures examined, no loss of reduction were reported. ROM assessment showed good results with an average arc of 113.1°. Excellent to good Broberg-Morrey and MEPI score were reported. No cases of avascular necrosis nor post-traumatic osteoarthritis resulted in our series. Complications occurred in 16.6% of the patients. Conclusion: Coronal shear fracture represents a challenging injury to treat. Anatomical reduction and the use of cannulated self-tapping headless screws from posterior provide a stable fixation, high union rates and good elbow function, with a low cartilage damage and risks of necrosis over 2 years of follow-up. Level of evidence: Therapeutic III.

Abstract

Introduction: Coronal shear fractures of the distal humerus represent an uncommon lesion and could be burdened by high complications. This complex lesion requires an accurate reduction and surgical fixation for a better outcome. Different techniques have been described, however no standard protocol have been proposed. Purpose of this retrospective study, is to evaluate the clinical and radiological outcome with posterior cannulated self-tapping headless screws followed by an early-active-motion protocol and to outline the surgical tips and tricks for different fracture patterns. Materials and methods: From 2013 to 2019, a consecutive series of 24 patients with coronal shear fracture undergoing ORIF were included in the study. Fractures were classified according to Dubberley’s classification. Cannulated self-tapping headless screws were used to fix the fragments. When necessary, additional cannulated half-threaded screws on the lateral edge of the humerus were used, as well as bone chips and fibrin sealant on severe comminution. All patients underwent an assisted early-active-motion rehabilitation protocol. Mean follow-up was 30 months; patients underwent standard X-rays and clinical outcome assessment with range of motion, Broberg and Morrey score and MEPI score. Results: Surgical fixation with headless screw guaranteed complete healing of all shear fractures examined, no loss of reduction were reported. ROM assessment showed good results with an average arc of 113.1°. Excellent to good Broberg-Morrey and MEPI score were reported.
