Base wedge osteotomy BerlinOperation procedure

The treatment involves a wedge-shaped adjustment at the base of the first metatarsal bone to correct a pronounced hallux valgus. By removing a wedge and then closing the resulting gap in the bone, the head of the first metatarsal can be guided towards the head of the second metatarsal. This reduces the spread of the first and second metatarsal bones. The intention of the operation is to bring the metatarsophalangeal joint and the "sesamoid bones" back into alignment. This operation doesn´t allow full weight bearing immediately. Depending on the bone strength and stability of the implant, the foot can be loaded early on. As a rule, however, a relief period of 4 weeks on forearm crutches is necessary after the operation. The treatment is only symptomatic, as no instabilities that have led to the metatarsal bones moving apart are treated.

This operation can be used to correct pronounced hallux valgus deformities, in cases where the postoperative relief time must be reduced as much as possible under all circumstances.
