Procedure specific checklist % who completed each step during phase-I.

Procedure-specific checklist item	VR	SG	p-value
Guidewire Insertion (wire inserted at appropriate starting point and angle)	70%	50%	0.325
Entry reamer selection (user selects correct reamer, assembles it in his/her hand)	30%	50%	0.325
Nail assembly (user assembles nail, guide, and locking mechanism)	30%	0%	0.1053
Nail insertion (user inserts nail in correct orientation and angle)	90%	30%	0.01
Proximal Interlock Guides (User selects correct triple guides and inserts through proximal drill guide)	70%	10%	0.01
Proximal Interlock Screw (User places from medial to lateral, through nail in static position)	70%	30%	0.09
Average number and % of steps completed correctly by each participant	1.5 (63%)	3.8 (25%)	0.002*

Statistical analysis was performed using Statistical analysis was performed using Fisher’s exact with Bonferroni correction, p=0.008. Although the percent of students who completed each step successfully was not significantly different between the two groups, the average number of steps completed correctly by each student (analyzed using Mann-Whitney with Bonferroni correction p<0.008), was significant.
