[Modified Metaizeau's technique for the treatment of radial neck fractures of Judet III or IV in children].

OBJECTIVE

To explore the clinical effect of modified Metaizeau's technique for radial neck fractures of Judet II or IV in children, summarizing the value of clinical application.

METHODS

From May 2014 to March 2017, 32 children of Judet III or IV radial neck fractures were treated with percutaneous Kirschner wire poking reduction and closed reduction with elastic intramedullary nailing fixation, including 21 boys and 11 girls, aged from 5.7 to 10.6 years old with a mean of 7.2 years old. The modified An-Morrey functional rating index were used to evaluate elbow range of motion, myodynamia, stability, and pain preoperatively and 1 year postoperatively in all the patients.

RESULTS

All patients were available for an average follow-up from 12 to 15 months. No complications such as incision infection, wire or nail tail irritation and avascular necrosis of radial head and epiphyses was occurred. The fracture achieved solid healing at 8 to 10 weeks after operation. The modified An and Morrey functional score improved from 58.69±5.80 before operation to 99.13±1.79 at 1 year after operation, there was obvious difference of scores between preoperative and postoperative at 1 year.

CONCLUSIONS

Modified Metaizeau's technique is a reliable and good treatment for Judet III or IV radial neck fractures in children, which has advantages of few complication, minimal invasion, quick fracture union and good recovery of elbow joint.
