Abstract
1. A modification of the Keller's arthroplasty is described, in which one of two types of distractor–intramedullary wire and external staple–is used to maintain normal length of the great toe for three weeks after operation.
2. The results of the modified operation are analysed. They appear to show that the use of a distractor can be expected to produce an improved end result and to aid post-operative wound healing.
3. The possible reasons for the improvement in results are discussed.
4. The intramedullary wire and the external staple are compared with respect to ease of introduction, effectiveness in maintaining distraction and end results.
