Summary

Extra-articular distal-third humeral shaft fractures are difficult to treat because stable fixation must be achieved while minimizing soft-tissue injury and the risk of nerve damage. Posterior double plating is a commonly used technique but requires extensive surgical exposure and routine handling of the radial and ulnar nerves. Anterior reversed proximal humeral locking plate system (PHILOS) fixation has emerged as a potential alternative that may provide adequate stability with less soft-tissue disruption.

This randomized controlled trial compares anterior reversed PHILOS plating with conventional posterior double plating in adult patients with extra-articular distal-third humeral shaft fractures. The study evaluates functional outcome using the Mayo Elbow Performance Score (MEPS) as primary outcome. Sexondary outcomes include: fracture union, operative parameters, range of motion, and complications including nerve injury, infection, and postoperative stiffness.

Conditions

  • Humeral Fracture

Interventions

DEVICE

Reversed PHILOS Plate

Fixation of extra-articular distal-third humeral shaft fractures using a reversed proximal humeral internal locking system (PHILOS) plate applied to the anterior surface of the humerus through an anterior approach. The construct was secured with locking screws proximal and distal to the fracture site.

DEVICE

Posterior Double Plate Fixation

Fixation of extra-articular distal-third humeral shaft fractures through a posterior approach using orthogonal double plates applied medially and posterolaterally after fracture reduction. Both radial and ulnar nerves were identified and protected during the procedure.
