Multivariate regression analysis of possible risk factors for post-operative wound infections in patients with a unilateral calcaneal fracture surgery with ORIF via ELA

Risk factor	p value	Odds ratio	Confidence interval
ASA classification	0.015	0.377	0.172–0.828
BMIa	0.138	1.070	0.978–1.171
Concomitant foot or lower leg fracture	0.650	0.756	0.225–2.534
In- or outpatient managementa	0.630	0.801	0.325–1.974
Closed suction drain placement	0.003	0.294	0.133–0.651

ORIF open reduction and internal fixation, ELA extended lateral approach
