Abstract
Aims: Tension band wiring is a widely accepted method for internal þxation of olecranon fractures. Plate þxation is suggested for the more complex olecranon fractures, but little is known about the speciþc risk factors for failure of tension band wiring. The aim of this study was to analyze the inßuence of fracture comminution, associated elbow instability and fracture extension into the coronoid process on the outcome of tension band wiring for olecranon fractures. Methods: From 1996 to 1998, forty-four olecranon fractures were treated consecutively at out institution using tension band wiring. All patients returned for a clinical and radiographic exam performed by two observers independent of the treating surgeon. Pain and satisfaction were determined using visual-analogue scales (VAS) and clinical results were graded using the Mayo Elbow Performance Score (MEPS) and the DASH questionnaire. Patients were followed for 3 to 6 years. Results: At most recent follow-up, the mean VAS score for pain was 2.0, mean extension was 3.6û and mean ßexion was 137.2û. According to the MEPS the results were graded as good or excellent in 78% of the patients. Five patients were disabled for activities of daily living according to the DASH questionnaire. All but one fracture healed. Fracture comminution did not affect the outcome. Worse results were associated with elbow instability and fracture extension into the coronoid. Conclusions: Tension band wiring provided satisfactory results for the treatment of olecranon fractures in the presence of fracture comminution, but worse results were obtained in the presence of elbow instability and fracture extension into the coronoid.
