Olecranon Osteotomy Exposure for Distal Humeral Fracture Treatment

Area of Science:

• Orthopedic surgery
• Traumatology

Background:

• Olecranon osteotomy (OO) is a common surgical approach for treating intra-articular distal humeral fractures.
• A chevron-shaped osteotomy enhances fracture reduction and provides a larger surface area for healing.

Purpose of the Study:

• To describe the technique and outcomes of olecranon osteotomy for distal humeral fracture treatment.
• To highlight the advantages of OO in improving surgical exposure and facilitating accurate fracture repair.

Main Methods:

• The procedure involves preoperative planning, patient positioning, a posterior skin incision, ulnar nerve mobilization, chevron OO at the non-articular bare area, open reduction and internal fixation of the humerus, and osteotomy fragment fixation with a precontoured plate.
• Meticulous attention is paid to reducing the osteotomy fragment by examining the articular surface of the trochlear notch.

Main Results:

• OO provides superior exposure compared to alternative techniques like triceps splitting or reflecting.
• The OO technique has not been associated with triceps weakness.
• Osteotomies demonstrate union in all reported cases, with good-to-excellent outcomes comparable to alternative methods.

Conclusions:

• Olecranon osteotomy is an effective technique for achieving adequate exposure, accurate reduction, and stable fixation of distal humeral fractures.
• The chevron OO facilitates precise reduction and stable fixation, contributing to successful treatment outcomes.
