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.
ObjectiveTo investigate the clinical features of ankle fractures involving Tillaux-Chaput in adults, and to observe the surgical effectiveness. MethodsBetween May 2009 and May 2013, 15 adult patients with ankle fractures involving Tillaux-Chaput were treated by open reduction and internal fixation. There were 12 males and 3 females, with an average age of 32 years (range, 19-45 years). The causes included sport injury (8 cases), traffic accident injury (5 cases), and falling injury from height (2 cases). The left ankle was involved in 5 cases and the right side in 10 cases. There were 2 open fractures (Gustilo type I) and 13 close fractures. Five patients had single Tillaux-Chaput fractures. The mean time between injury and surgery was 8.5 days (range, 3 hours to 15 days). According to the Lauge-Hansen classification, there were 9 cases of supination-external rotation, 5 cases of pronation-external rotation, and 1 case of pronation-abduction. ResultsPrimary healing of incisions was obtained in 13 patients without infection and neurovascular injury; 2 patients had superficial infection which was cured after oral antibiotics and dressing change. All cases were followed up for 23 months on average (range, 13-36 months). X-ray films showed complete fracture healing at 10-16 weeks postoperatively (mean, 13 weeks) in all cases. The mean American Orthopaedic Foot and Ankle Society (AOFAS) score was 87 (range, 78-99), with an excellent and good rate of 80% (excellent in 9 cases, good in 3 cases, and fair in 3 cases). ConclusionOpen reduction and internal fixation for ankle fractures involving Tillaux-Chaput in adults can achieve excellent effectiveness.
