Management of splint bone fractures

Abstract

Owing to their superficial position on the lower limb, close approximation to the suspensory ligament and rather insubstantial nature, it is unsurprising that splint bone fractures are commonly encountered in practice. These fractures can be caused by either external or internal trauma, and can take a number of configurations. Treatment and prognoses differ depending on the location, configuration and age of the fracture, as well as involvement of adjacent soft tissue structures, the third metacarpal or metatarsal bone, or the carpometacarpal or tarsometatarsal joints. However, despite the frequency of splint bone fractures, there is no consensus regarding appropriate treatment. Management consists of conservative or surgical strategies, both of which have distinct advantages and disadvantages. Most reports consist of small case series and clinical experience. This review article presents current information and guidance for managing splint bone fractures.
