Partial foot amputations may not always be worth the risk of complications
In reply: We appreciate the opportunity to reply to two letters submitted in response to our article.1
Both letters agree that our perspective piece was mainly based on evidence about the outcomes for people with transmetatarsal amputation, noting that most people undergo amputation of the toe(s) or toes and metatarsals. As highlighted in our supporting work,2 there are comparatively few investigations focusing on outcomes for people with digital, ray, tarsometatarsal and transtarsal amputation. Despite this, we stand by our interpretation that the rates of complications and reamputation seem very similar across levels of partial foot amputation.1,2 To illustrate, a study that stratified large numbers of people by level of partial foot amputation found that the rates of ipsilateral reamputation were not statistically different in groups with either toe, ray or mid-foot (ie, transmetatarsal, Lisfranc and Chopart) amputation.3 Given these data, we argue that our synthesis of published outcomes on the rates of reamputation and other complications for people with different levels of partial foot amputation was reasonable. Our article should not be considered a comparison between the outcomes of transmetatarsal and transtibial amputation.
