Medial mini-open versus percutaneous pin fixation for type III supracondylar fractures in children.
BACKGROUND
The present objective was to compare medial mini-open and percutaneous treatment of pediatric supracondylar fractures according to fluoroscopy time, duration of surgery, and iatrogenic ulnar nerve injury.


METHODS
A total of 104 Gartland type III supracondylar humerus fractures were prospectively evaluated between 2011 and 2013. Patients were divided into 2 groups according to type of fixation. In Group A (41 patients), medial pin was inserted with mini-open incision with 2 lateral pins inserted percutaneously. In Group B (63 patients), all pins were inserted percutaneously. Mean follow-up time was 14.1±1.2 months in Group A, and 14.6±2.1 months in Group B. All patients were postoperatively evaluated for nerve injury with both motor and sensory function assessment. Length of surgery, total fluoroscopy time, fluoroscopy time for medial pin insertion, Baumann's angle, humeral capitellum angle, final carrying angle, and range of motion were recorded.


RESULTS
Sensorial evaluation showed that Group A had 3 poor, and 1 fair results, and Group B had 2 poor, and 1 fair results. No statistically significant differences were observed, including no differences in either surgery or total fluoroscopy times between groups. However, fluoroscopy time during medial pin placement was significantly lower in the mini-open group.


CONCLUSIONS
In conclusion, similar results of both techniques were observed, and both carry risk of iatrogenic ulnar nerve injury. Medial pin placement is easier and less demanding when used with mini-open technique.
