Abstract
Introduction: The aim of this study is to present a modification of the single tension band technique for the treatment of olecranon fractures, using a double tension band with smaller wires, preserving all the biological parameters for fracture fixation, in an effort to decrease related complications.
Material: Thirty-three patients with olecranon fractures treated with a double tension band fixation. Surgical Technique: Through a posterior approach the fracture is reduced keeping all principles for biologic fixation and stabilized with two parallel small K-wires inserted from the olecranon process and exit through the anterior cortex of the ulna. Then the extensor carpi ulnaris and flexor carpi ulnaris are partly elevated from the ulna and two 1.5-mm transverse drill holes are made through the ulna 3 and 4 cm distal to the fracture. Two 22-gauge wires are passed through the proximal and distal holes, bent into a figure of 8 over the dorsal ulna and simultaneously tightened. The proximal ends of the K-wires are bent and impacted into the olecranon process.
Eleven patients needed supplemental fixation with screws. All patients mobilized the first postop day.
Results: All the fractures consolidated. All patients but two regained full range of motion. No hardware failure was noted except one patient in whom one band was broken but without clinical relevance.
Conclusion: It seems that a double tension band fixation despite the smaller material utilized, provides a very stable construct, permitting early mobilization. Furthermore two bands tensioned independently provide greater compression forces at the fracture site and offer a back up in case that one band fails.
