- Keller's operation
- an operation for hallux valgus (see also bunion) or hallux rigidus that involves an excision arthroplasty of the metatarsophalangeal joint, at the base of the big toe. The toe will be slightly shorter and floppy, but usually this improves alignment and range of movement [L. Keller (1874–1959), US surgeon]
