Abstract:
OBJECTIVE:To explore clinical effects of micro external fixator for the treatment of supracondylar fracture of humerus in children.
METHODS:From October 2017 to December 2018, 20 children with supracondylar fracture of humerus (treatment group) were admitted and treated with micro-external fixation after closed reduction, including 14 males and 6 females, aged from 6 to 14 years old with an average of (7.9±2.4) years old, classified to Gartland Ⅲ. Thirty nine children with supracondylar fracture of humerus were admitted as control group from January 2015 to September 2017, and treated with closed reduction Kirschner wire fixation. Among them, including 24 males and 15 females, aged from 6 to 14 years old with an average of (8.1±1.9) years old, classified to GartlandⅢ. Operation time, times of intraoperative fluoroscopy, and complications between two groups were observed and compared, Mayo scoring system at the latest follow up was used to evaluate clinical effect.
RESULTS:Twenty children in treatment group were followed up from 6 to 12 months with an average of (8.0±2.5) months, operation time was(30.10±12.50) min, times of intraoperative fluoroscopy was(10.00±2.50). Fifteen patients got excellent results, 3 good, 2 fair according to Mayo elbow joint scoring. No ulnar nerve injury moderate or severe elbow varus occurred in treatment group. Thirty-nine children in control group were followed up from 5 to 13 months with an average of (9.0±3.1) months, operation time was(45.60±18.90) min, times of intraoperative fluoroscopy was(19.00±5.60). Twenty-three patients got excellent results, 12 good, 3 fair and 1 poor according to Mayo elbow joint scoring. One child occurred ulnar nerve injury and recovered at the final follow-up, 1 child occurred severe cubitus varus and 2 children occurred moderate cubitus varus. There was no statistical difference in clinical effect between two groups (
CONCLUSION:Treated with closedreduction and mini external fixator fixed on children humerus condyle fracture could receive the same clinical result as closed as reduction gram needle fixation, which has advantages of shorter operation time, less times of intraoperative fluoroscopy, not esay to damage ulnar nerve during operation, less incidence of moderate and severe cubitus varus deformity after operation, and the permeation was simple.
