Comparison of the Number of Complications per Lengthening Session with Circular Fixation or Motorized Nail

Complication Category	Circular Fixation*	Motorized Nail*	P Value
I	1.1 ± 0.8 (1; 0-3)	0.4 ± 0.6 (0; 0-2)	0.02
II	0.6 ± 0.9 (0; 0-3)	0.4 ± 0.5 (0; 0-1)	0.78
IIIA	0.3 ± 0.5 (0; 0-1)	0.2 ± 0.4 (0; 0-1)	0.62
IIIB	0.4 ± 0.7 (0; 0-2)	0.2 ± 0.4 (0; 0-1)	0.33
Total complications	2.4 ± 1.3 (2; 1-5)	1.2 ± 1.1 (1; 0-4)	0.02

^*The values are given as the mean and the standard deviation, with the median and the range in parentheses. The circular fixation group included fourteen lengthening sessions in fourteen patients, and the motorized nail group included fifteen lengthening sessions in thirteen patients.
