Delayed Diagnosis of a Ligamentous Lisfranc Injury on a Bomber Task Force Member.

Abstract

The tarsometatarsal joint, or Lisfranc joint, is an extremely important anatomical structure and injury to it has been shown to cause long-term disabling ramifications. With a wide spectrum of injury involvement, from fracture dislocations to sprains, it is important to establish a diagnosis early to guide management. Although the more extreme higher energy fracture dislocations are more widely studied, there remains a paucity of literature on lower energy purely ligamentous injuries, especially among military service members.1 The deployed setting provides an extra layer of complexity in determining a musculoskeletal injury etiology for the provider, especially in resource-limited areas. When a high level of suspicion for Lisfranc injury exists based upon clinical presentation and in the setting of negative X-rays, more prudence should be placed on additional workup. This will guide decision-making for possible expedited stateside return for the patient and better odds of follow-up care. The following case demonstrates a unique scenario of an undiagnosed, purely ligamentous Lisfranc tear in a 23-year-old woman in a deployed environment with late presentation to an orthopedic surgeon stateside. Furthermore, emphasis is placed on factors that led to her delayed diagnosis and how advocating for advanced imaging modalities up-front can expedite care.
