Subperiosteal amputation

Subperiosteal amputation (historical; a. subperiostalis) is a surgical operation to remove a limb or part of it by cutting the bone under the periosteum.

With this amputation, the periosteum is not cut off, but is carefully separated from the bone. This allows the periosteum to grow into the stump and promote callus formation at the end of the stump. By preserving the periosteum, this amputation method reduces the risk of osteomyelitis and ensures better healing of the stump.

This type of amputation was used in surgical practice in the past, when modern prosthetic methods had not yet been developed. Currently, subperiosteal amputation is already outdated and practically not used.
