Table 3.

Comparison of the major complications in three groups.

	ESIN-RPS $(\bar{x} \pm s)$	KW-R $(\bar{x} \pm s)$	ESIN-A $(\bar{x} \pm s)$	P₁/t₁ or χ²	P₂/t₂ or χ²	P₃/t₃ or χ²
Mal-union	0	4	2	/	0.696/0.153	/
Nerve injury	0	0	2	/	/	/
Infection(superior/deep)	0	6	0	/	/	/
Tendon injury	1	1	0	0.522/0.361	/	/
Secondary fracture	0	2	0	/	/	/
Total	1	13	4	0.034/4.480	0.363/0.828	0.087/2.633

Where P is the statistical probability, t is the statistical quantity, P₁/t₁ is ESIN-RP vs. KW-R, P₂/t₂ is ESIN-RP vs. ESIN-A, and P₃/t₃ is KW-R vs. ESIN-A. χ² is the Fisher's exact test result.
