Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Subject has Lisfranc injury that was treated within 28 days of injury.
  • Subject must be enrolled in study between 6 and 8 weeks from time of initial fixation operation.
  • The patient must be medically fit for anesthesia
  • Subject is willing and able to provide written informed consent for trial participation
  • Subject is willing and able to comply with the study protocol including return for all follow-up evaluations
  • Subject may have a bony, ligamentous, or combined lisfranc injury
  • Demonstrated instability of the lisfranc complex on static, stress view or CT radiography.
  • Associated injuries - other than the lisfranc complex - are permitted provided those injuries are not deemed to significantly influence the rehabilitation or recovery of the patient at the discretion of the enrolling surgeon
  • Adequate reduction to within 1mm of lisfranc complex at time of fixation
  • Hardware across the midfoot (tarsal-metatarsal joints 1-3)

Exclusion Criteria:

  • Subject has a significant pre-existing foot injury
  • Subject has a delay in initial treatment greater than 28 days from time of injury
  • Subject has an active infection in the area of surgical approach requiring surgical debridement
  • Subject has concomitant injury which, in the opinion of the attending surgeon, is likely to impair rehabilitation or prolong fracture healing time (another long bone fracture, ipsilateral limb injury)
  • Subject has a history of rheumatoid arthritis, Diabetes, fibrous dysplasia, chronic renal failure, Paget's disease, or osteopetrosis or any other pre-existing pathologic condition affecting the Lisfranc complex
  • Subject has a high risk of death from surgery (ASA physical status Class V)
  • Subject is likely unable to maintain follow-up(no fixed address, plans to move out of town in the next year, states unable to comply with protocol, etc.)
  • Subject has cognitive impairment or language difficulties that would impede the valid completion of questionnaires
  • Subject is pregnant
  • There has been loss of fixation or reduction prior to enrollment
  • Previous corrective foot surgery
  • Associated fracture of calcaneus, talus, or tibial plafond.
  • Pathologic fracture
  • Loss of fixation or reduction prior to enrollment
