Comparison of the distance between the first and the second metatarsal joint and VAS scores between pre- and post-operation ($\overline{x}\pm \text{s}$)

Time	Distance between the first and the second metatarsal (mm)	VAS score
Pre-operation	8.9 ± 3.7#Δ	7.1 ± 1.0#Δ
Three months after operation	1.7 ± 0.4*	1.8 ± 0.6*
Six months after operation	1.8 ± 0.4*	1.7 ± 0.9*
Last follow-up	1.9 ± 0.5*	1.5 ± 0.7*

^*Compared with pre-operation value, P < 0.05

^#Compared with the value at 3 months after operation, P < 0.05

^ΔCompared with the value at 6 months after operation, P < 0.05
