Case Overview

This case study involves an elderly individual, aged around 70, with a history of diabetes. The patient suffered a Lisfranc fracture in their left foot in March of an unspecified year.

Following the diagnosis, they underwent surgery for hardware placement in April. However, complications arose postoperatively due to an infection that necessitated hardware removal in September of the same year.

Two years later, the patient began experiencing issues with the toes on their left foot. This led to the amputation of the first and second digits and partial amputation of the third digit. It is alleged that this individual has a history of noncompliance with diabetes management and insulin use.

An expert in Foot & Ankle Surgery was sought to review medical records and provide an opinion on whether the subsequent toe amputations were related to the initial foot fracture.

Questions to the Orthopedic Surgery expert and their responses


How often do you perform surgery for patients with foot fractures, including Lisfranc injuries, and manage postoperative care?

I have been practicing orthopedic trauma surgery at our Level I trauma center for 15 years now, treating thousands of patients with fractures and injuries to the musculoskeletal system, including foot injuries. Essentially, every day I manage traumatic foot injuries.


What are the most pertinent measures that surgeons can perform to minimize the incidence of postoperative infection in patients with diabetes?

To minimize the incidence of postoperative infection in patients with diabetes, several measures should be implemented. These include good preoperative prophylaxis, sterile surgical technique, proper sterile dressings postoperatively, and close monitoring.


What pertinent criteria should be used to determine if this patient's subsequent toe amputations are related to her previous foot fracture?

Determining if this patient's subsequent toe amputations are related to her previous foot fracture would require further review of the time course and postoperative clinical events.
