NCT04831645

Brief Summary

The purpose of this study is to determine the clinical efficacy of a novel sustained dynamic compression intramedullary nail for tibiotalocalcaneal (TTC) arthrodesis utilizing longitudinal weight-bearing computed tomographic imaging. Of particular focus will be assessment of compressive element recovery and its relation to fusion development over time and weight-bearing status. Additionally, the study will incorporate longitudinal fusion assessment to evaluate differences between three-dimensional weight-bearing computed tomography (WBCT) scans and two-dimensional radiographs (X-rays) at multiple points of the fusion process. Finally, the study will evaluate the differences in WBCT-based fusion assessment between automated and manual methodologies for fusion area calculation.

Outcome Measures

Primary Outcomes (1)

  • Fusion

    Joint Fusion, as measured by radiographs and CT scans. Fusion rates will be assessed based on varying CT fusion areas. Fusion rates based on X-Ray vs CT assessment will also be compared. CT fusion rates based on varying fusion areas will be compared with PROM data to assess which fusion area actually corresponds to increased function and reduced pain.

    Pre-Operative to 1 year post-surgery

Secondary Outcomes (6)

  • VAS

    Pre-Operative up to one year post-surgery

  • VR-12

    Pre-Operative up to one year post-surgery

  • FFI-R

    Pre-Operative up to one year post-surgery

  • FAAM

    Pre-Operative up to one year post-surgery

  • AOS

    Pre-Operative up to one year post-surgery

  • +1 more secondary outcomes

Other Outcomes (1)

  • Automated vs Manual Fusion Assessment

    Up to one year post-surgery

Interventions

DynaNailDEVICE

Utilization of a novel dynamic compression pseudoelastic intramedullary nail

Tibiotalocalcaneal (TTC) arthrodesis with a novel dynamic compression intramedullary nail.

Also known as: Subtalar Arthrodesis, Tibiotalar Arthrodesis

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients of the Orthopedic Foot and Ankle Center with end-stage tibiotalar (ankle) and talocalcaneal (subtalar) joint arthritis from any etiology will be eligible to enroll in the study. In general, tibiotalar and subtalar arthritis is caused by trauma. Traumatic injuries have no predilection for race, religion, cultural background, etc. Therefore, all demographic groups will have access to this study and should be represented.

You may qualify if:

  • Meets indications for TTC arthrodesis and receives the DynaNail implant
  • Able to understand the requirements of the study
  • Willing to comply with the study protocol
  • Sign an Informed consent
  • years of age or older

You may not qualify if:

  • Investigator determines that the subject is unlikely to comply with the requirements of the study
  • Non-English speaker
  • Blind
  • Illiterate
  • Prisoner
