A bone-wedge is resected at the base of the first metatarsal bone in order to correct a pronounced hallux valgus. By extracting a wedge and subsequently closing the resulting gap in the bone, the first metatarsal bone head can be re-directed towards the second metatarsal bone head. In this manner, the splay between the first and second metatarsal bones can be reduced. By doing so, a reset of the metatarsophalangeal joint and the sesamoid bones is achieved. The loading capacity depends on the bone solidity and stability of the implant. Often, the foot can be burdened early, without crutches. As a general rule, a relief time of 4 weeks on crutches is required after the procedure.
The treatment is merely symptomatic, due to the fact that no instabilities that have led to the drifting apart of the metatarsal bones are treated.
It can be applied for the correction of pronounced hallux valgus misalignments, in cases that require the post-operative relief time to be reduced as much as possible under any circumstance.
