Olecranon Fracture Fixation Techniques

Olecranon fractures, resulting from direct trauma or avulsion by the triceps tendon, represent a common challenge in adult and paediatric orthopaedics. The primary objective of surgical fixation is to restore articular congruity, ensure stable osteosynthesis under tensile forces generated during elbow motion and facilitate early rehabilitation. Traditional methods include tension band wiring and plate fixation, each with recognised advantages and limitations. Tension band wiring converts tensile forces into compression at the fracture site but may cause soft-tissue irritation and hardware migration. Plate fixation offers rigid stabilisation, especially in comminuted or osteoporotic bone, yet carries a risk of wound complications from implant prominence. Intramedullary screw fixation and novel constructs—such as anchor loop plates and specialised tension band configurations—have emerged to address these shortcomings. Innovations focus on optimising biomechanical stability, minimising soft-tissue irritation and reducing the need for secondary surgery.

Research from Nature Portfolio

A recent biomechanical investigation evaluated a novel screw-based tension band configuration in comparison with standard Kirschner-wire tension band wiring and a combined intramedullary screw with wiring technique. Using a synthetic bone model of a simple olecranon fracture under cyclical loading and pull-out testing, the enhanced screw construct demonstrated smaller fracture gaps at high flexion angles and significantly greater resistance to failure. The maximum load to failure was markedly higher than for either traditional tension band wiring or the hybrid intramedullary approach, indicating superior mechanical performance. This advance suggests potential for reduced fixation failure and improved postoperative stability in clinical practice.

The graph below shows the total number of articles in olecranon fracture fixation techniques across all publications each year (not limited to Nature Index journals).

Technical terms

Tension band wiring (TBW): A fixation method using wires or cables configured to convert tensile forces from muscle contraction into compressive forces across a fracture.

Plate fixation (PF): The application of a contoured metal plate and screws to bridge and stabilise a fracture, typically offering rigid support in comminuted or osteoporotic bone.

Intramedullary screw fixation: The insertion of a cannulated screw into the medullary canal of the ulna to achieve internal compression of simple olecranon fractures.

Anchor loop plate: A low-profile plate design incorporating integrated loops or hooks for soft-tissue fixation and enhanced fragment control under tensile loading.

Ding’s screw tension band wiring (DSTBW): A modified tension band technique employing specialised screws to anchor the wire construct, improving mechanical stability and reducing wire migration.
