This is a prospective investigation to assess the clinical outcomes of patients with a subtalar arthrodesis with the Sustained Dynamic Compression Intramedullary Nail (DynaNail Mini). The study plan is to enroll 60 patients.\n\nPatients with end-stage 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 as part of the Surgical Outcomes System (SOS) Global Registry: Visual Analog Scale (VAS) for pain, Veterans RAND 12 Item Health Survey for function, Foot Function Index - Revised for function and pain, the Foot and Ankle Ability Measure (FAAM) for function, and the American Orthopaedic Foot and Ankle Society (AOFAS) scales for pain, function, and alignment. After informed consent, they will then be scheduled for surgery in a routine fashion.\n\nThe following surgical procedure is standard of care. The surgical procedure will involve subtalar (talocalcaneal) joint preparation through a lateral approach. The use of supplemental bone graft is at the discretion of the treating surgeon but must be documented. The MedShape DynaNail Mini 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.\n\nThe patient will return to clinic for visits at the following intervals after surgery: 6 (+/- 1) weeks, 14 (+/- 1) weeks, 6 months (+/- 2 weeks), and 12 months (+/- 2 weeks). At each of these time points, the same SOS patient specific outcome questionnaires will be administered. 3-view X-rays will be taken at each of these visits to assess the amount of travel of the Mini compressive element. At 15 (+/- 1) weeks post-op, a CT scan will be obtained to assess healing. Additionally, a radiographic and clinical follow-up form will be filled out at each of the following follow-up visits: 6 weeks, 14 weeks, 6 months, and 1 year.\n\nPatients will be identified in the clinic by an attending orthopaedic foot and ankle surgeon or his physician assistant based on clinical exam and radiographic findings. Inclusion criteria include anyone over age 18 who has end-stage subtalar arthritis and has failed nonoperative management. Typically, these patients have multiple medical comorbidities and therefore the exclusion criteria will be patients who are not healthy enough to undergo surgery. Additional exclusion criteria include non-English speakers, and patients that are blind, illiterate, or are prisoners. Additionally, pregnant women will be excluded. Patients of all racial, religious, and cultural backgrounds will be included in this study."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients will be identified in the clinic by an attending orthopaedic foot and ankle surgeon or his physician assistant based on clinical exam and radiographic findings.
