Compression Nail for Tibiocalcaneal Arthrodesis

Study Purpose

The purpose of this study is to determine the clinical efficacy of a novel dynamic compression intramedullary nail for tibiotalocalcaneal (TTC) arthrodesis

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03780452
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This proposal is a collaborative effort of MedShape Inc. It is a prospective investigation to assess the clinical outcomes of patients with a tibiotalocalcaneal arthrodesis with the Dynamic Compression Intramedullary Nail (DynaNail). We are planning to enroll 30 patients. The assignment of the device is at the discretion of the standard of care provider, not the study investigator. Patients with end-stage tibiotalar (ankle) and talocalcaneal (subtalar) joint arthritis from any etiology will be asked to enroll in the study. After informed consent, the patients will be asked to complete the following patient reported outcomes questionnaires (standard of care for all patients in the Foot and Ankle section): 100mm VAS for pain, Short form-36 (SF-36), and the Foot and Ankle Ability Measure (FAAM). After informed consent, they will then be scheduled for surgery in a routine fashion. REDCap database will be used to allow on-line data entry. The following surgical procedure steps and follow-ups are standard of care at the University of Alabama at Birmingham. The surgical procedure will involve both tibiotalar and talocalcaneal joint preparation through any approach (lateral, posterior, anterior with sinus tarsi). The use of supplemental bone graft is at the discretion of the treating surgeon but must be documented. The MedShape DynaNail will then be inserted according to the manufacturer's technique. The patient will be placed in a short leg splint and kept non-weight bearing. The patient will be discharged from the hospital when medically ready and follow-up in two weeks. At two weeks, the patient will return to clinic for a standard of care visit and their splint will be removed. A non-weight bearing lateral radiograph of the hind foot will be taken to assess the amount of travel of the compressive element. This radiograph is not standard of care. The patient will be placed in a non-weight bearing cast. The patient will then be asked to return in two weeks (4 weeks post-operatively). This visit is not standard of care. At this time another non-weight bearing lateral radiograph will be taken to assess the amount of travel of the compressive element. The patient will be asked to return at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery as is standard of care for this surgery. At each of these time-points, the same patient specific outcome questionnaires will be administered. For any non- standard of care radiographs patients will be asked to take a urine pregnancy test prior to any radiographs being taken. Patients will be identified in the clinic by an attending orthopaedic foot and ankle surgeon, his clinical fellow, or his physician assistant based on clinical exam and radiographic findings. Inclusion criteria include anyone over age 18 who has ankle and subtalar arthritis and has failed nonoperative management. Typically, these patients have multiple medical comorbidities and therefore the only exclusion criteria will be patients who are not healthy enough to undergo surgery. Patients of all racial, religious, and cultural backgrounds will be included in this study.
