Lisfranc Injuries Clinical Trial
Official title:
The FIRM Trial - A Randomized Clinical Trial Evaluating Fixation In-situ vs Removal for Midfoot Lisfranc Injuries
Injuries to the midfoot tarsometatarsal joint, or Lisfranc joint, are notoriously debilitating. Poor functional outcomes following Lisfranc injuries have motivated surgeons to look for potential improvements in post-operative care. There are currently no evidence-based guidelines to direct implant removal for patients with operatively treated Lisfranc injuries. Routine implant removal has significant implications related to health care costs, lost time from work, potential surgical complications, and possibly functional impairment. Therefore, stakeholders including patients, surgeons, employers, and administrators will benefit from evidence-based guidelines for implant removal following operatively treated Lisfranc injuries. To date, there has not been a prospective randomized study evaluating the efficacy of implant removal compared with implant retention for Lisfranc injuries. The aim of this study is to directly compare patient-reported and radiographic outcomes, in order to provide robust evidence for optimal post-operative treatment regimens regarding implant removal or retention for operatively treated Lisfranc injuries.
This study is a multicenter, randomized clinical trial comparing implant retention (Retention Group) to scheduled implant removal (Removal Group) in 100 skeletally mature patients with Lisfranc injuries previously treated with screw and/or plate fixation. The primary outcome measure is the validated, patient-reported Foot and Ankle Ability Measure (FAAM) at 1-year post initial Lisfranc injury. Secondary outcome measures include: 1. American Orthopedics Foot and Ankle Midfoot Score (AOFAS), 2. patient-reported Visual Analogue Scale (VAS) for Foot and Ankle, 3. range of motion, 4. radiographic assessment of Lisfranc reduction, 5. comparative cost analysis between treatment groups. This study will follow patients for 1-year post-injury. Patients, surgeons, employers, and administrators will benefit from an evidence-based approach to implant removal following operatively treated Lisfranc injuries. This study will allow orthopaedic surgeons to counsel patients regarding the advantages and disadvantages of implant retention compared with removal. This study will provide robust data to inform clinical decision making for surgeons and provide patients with information regarding expected functional outcomes following Lisfranc injuries. ;
