Abstract
Fractures of the olecranon are some among the most common injuries involving the upper extremity. Olecranon fractures occur as a result of direct or indirect trauma. Direct injuries are typically the result of a fall with impact on the dorsal aspect of the proximal forearm. During a fall on an outstretched hand, the distal aspect of the olecranon may be impacted into the trochlea, producing fracture by indirect trauma. Being intra-articular, displaced olecranon fractures need anatomical reduction, stable fixation, and early mobilization. Many methods have been described including inter-fragmentary screws with or without wires, Cables, plate and screws, tension band wiring or screws, intramedullary screws o nails, and bone fragment excision with reattachment of the triceps.
An ideal device for fixing these fractures should avoid the problems of metalwork irritation or migration and the risk of damaging anterior structures, should have a low complication rate, be easily reproducible by different surgeons; provide excellent union, and function rates; and be cost-effective.
TBW has been considered for a long time as the ”gold standard” of treatment for non-comminuted or minimally comminuted olecranon fractures. This technique rely on converting the tensile forces posteriorly to compression forces at the joint line anteriorly. Trust on TBW become decreasing with time because of the common complaints of wire-related pain or migration that necessitates frequent removal surgery and many biomechanical studies questioned its principle. The sum of the costs of treatment may be greater than the costs imposed by more advanced implants and technique that aims to avoid the pitfalls of the TBW.
