Abstract:
BACKGROUND:Humeral supracondylar fracture is a common fracture occurred in children. The selection of internal fixation for humeral supracondylar fracture remains controversial. OBJECTIVE:To compare the biocompatibility between internal fixation with Kirschner wire and bioabsorbable implants for humeral supracondylar fractures. METHODS: From January 2007 to January 2013, 246 cases of humeral supracondylar fractures, from Affiliated Hospital of Luzhou Medical Colege, were treated by internal fixation with Kirschner wire. Meanwhile, the studies on internal fixation for treating supracondylar fracture of humerus in children were searched. Efficacy was evaluated by preoperative and postoperative elbow range of motion and the incidence of cubitus varus, and the results were statisticaly analyzed, and compared with other therapeutic methods. RESULTS AND CONCLUSION:Al cases were folowed up for 6-36 months, averagely 18 months. According to Mayo elbow performance score, function of the elbow joint was excelent in 194 cases, and good in 48 cases, with good and excelent rate being 98.4%. Four cases suffered < 5° cubitus varus, with incidence rate of 1.63%. The internal fixation with Kirschner wire provided functional recovery of elbow joint, but the second stage operation was needed to pick out the wires. And it might be perplexed by Kirschner wire loosening or needle withdrawal, resulting in instable fixation. Bioabsorbable implants were effective in the treatment of supracondylar fracture of humerus. Bioabsorbable sticks would break down over time, without harming to human body or influencing imaging examination. Elbow function development of the epiphysis would not be affected. However, due to lack of large-sample observation, long-term effects of bioabsorbable implants for treating supracondylar fracture of humerus in children deserve further studies.
