The tension band technique for olecranon fractures yields good clinical outcomes however it is associated with significant complications. In many patients implants irritate overlying soft tissues and cause pain. This is mostly due to protrusion of the proximal ends of the K-wires or by the twisted knots of the metal wire tension band. Below we described 2 cases of olecranon fractures treated with a unique technique using FiberWire without any metallic implants. Technically the fragment was reduced and two K-wires were inserted from the dorsal cortex of the distal segment to the tip of the olecranon. K-wire was exchanged for a suture retriever and 2 strands of FiberWire were retrieved twice. Each of the two FiberWires was manually tensioned and knotted on the posterior surface of the olecranon. Bony unions could be achieved and patients had no complaint of pain and skin irritation. There was only a small loss of flexion and extension in comparison with that of the contralateral side and the patient did not feel inconvenienced in his daily life. Using the method described difficulty due to K-wire or other metallic implants was avoided. Background Olecranon fractures consist of approximately 10 of all fractures around the elbow. The tension band fixation is the commonest technique for relatively simple fractures. This technique combines intramedullary Kirsh-ner wires K-wires with a metal wire tension band. The AO tension band technique yields good clinical outcomes however it is associated with significant complications 1-3 . In many .
