Early Failure of Paragon28 Phantom Hindfoot Fusion Nail: A Case Report

Abstract

Category: Diabetes; Hindfoot; Trauma Introduction/Purpose: Tibio-talar-calcaneal (TTC) fusion nails are commonly used to treated acute ankle fractures in patients with diabetes, Charcot arthropathy or other comorbidities. Recently, Paragon28 released the Phantom Hindfoot Fusion Nail (Phantom nail) with a unique design feature-a proximal coil. Methods: We present the case of a diabetic patient with an ankle fracture-dislocation treated with the Paragon28 nail who experienced early implant failure. Results: A 48-year-old male with HIV, end-stage renal disease requiring hemodialysis, and insulin-dependent diabetes mellitus with severe peripheral neuropathy presented a trimalleolar ankle fracture-dislocation treated with a TTC nail. At his first follow- up, he presented with early implant failure at the nail-coil interface. Conclusion: The integrity of the Phantom nail, appropriate length, and placement of the flex coil require further evaluation. Unstable pathologies such as fractures may be better stabilized with a solid nail construct.
