  • CLINICAL OBSERVATION OF STELLATED PLATE FIXATION OF OLECRANAL AVULSION FRACTURE

    ObjectiveTo evaluate the clinical outcome of stellated plate fixation of olecranal avulsion fracture. MethodsA retrospective analysis was made on the clinical data from 24 cases of olecranal avulsion fracture treated with stellated plate between April 2007 and April 2012. There were 13 males and 11 females, with an average age of 32 years (range, 18-65 years). The causes of injury included falling injury (14 cases), sports injury (7 cases), and machine injury (3 cases). The left elbow was involved in 4 cases and the right side in 20 cases. The average disease duration was 11 hours (range, 3 hours-2 days). According to Colton's classification criteria, all cases were classified as type Ⅱ A (avulsion fracture). One case had supracondylar humeral avulsion fracture, and 15 cases had triceps tendon tears. ResultsAll the cases obtained healing of incision by first intention, without infection and ulnar nerve injury. The average follow-up period was 24 months (range, 18-48 months). All fractures healed after 6-10 weeks (mean, 7 weeks). According to Morrey's elbow performance score, the results were excellent in 17 cases, good in 4 cases, and fair in 3 cases, with an excellent and good rate of 87.5%. There was no significant difference in the elbow range of motion (ROM) between the injured side (136.0±16.2)° and normal side (143.1±2.9)° (t=2.007, P=0.052). The ROM of normal elbow was significantly larger than that of the injured side in 3 patients who achieved fair results (t=2.820, P=0.048), but no significant difference was found in patients who achieved excellent and good results (P>0.05). ConclusionThe stellated plate has good clinical outcome in treatment of olecranal avulsion fracture, which has advantages of simple operation, firm fixation, and early functional exercise.
