A new study published in the Journal of Orthopedic Surgery and Research aimed to discuss the surgical strategy, technical feasibility, and clinical efficacy of coronal shear fractures of distal humerus using the anti-sliding plate technique.

This study included 52 patients – 35 males and 17 females, were treated with the anti-sliding plate technique between 2012-2017. The average age of the patients was 40.4 years; they were classified according to the Dubberley classification system and treated with the anti-sliding plate technique. Long-term functional scores represented by the Mayo Elbow Performance Index and complications were evaluated.

Here, fractures were classified as – 11 type-IA; 5 type-IB; 16 type-IIA; 4 type-IIB; 13 type-IIIA; and 3 type-IIIB. All patients were treated with open reduction and internal fixation by the extensile lateral approach and completed a clinical and radiographic follow-up. The average Mayo elbow performance score was 90.6 points, with 36 excellent, 11 good and 5 fair results. While the average range of movement of the elbow joint was 3° (0-15°) for extension and 136° (90-150°) for flexion.

From the results, it was inferred that the anti-sliding plate technique follows basic AO principles and neutralizes the shearing force combined with lag screws and/or Kirschner wires after the anatomic reduction of the fracture. Additionally, it allows for the stable internal fixation of the fracture, which is critical for early mobilization and a good functional outcome.
