AI Article Synopsis
- Late-stage talar avascular necrosis (AVN) leads to severe damage in the talus, requiring surgical intervention like total ankle and talus replacement combined with hindfoot fusion.
- This study reviewed 18 patients who underwent this procedure from 2016 to 2020, focusing on aspects like pain relief, mobility, and joint alignment.
- The results showed significant improvements in pain and function, with a 100% success rate in joint fusion and minimal complications post-surgery.
Article Abstract
Late-stage talar avascular necrosis (AVN) results in devascularization of the talus with osteonecrosis and subchondral collapse. A combined total ankle and total talus replacement (TATTR) with hindfoot arthrodesis may be utilized for end-stage talar AVN with tibiotalar and hindfoot joint arthritis. The purpose of this study is to evaluate the short-term outcomes of combined TATTR with hindfoot arthrodesis. Patients who underwent a combined TATTR or TTR with a hindfoot arthrodesis (subtalar with or without talonavicular arthrodesis) from 2016 to 2020 were retrospectively reviewed. Patient demographics, comorbidities, and surgical data were collected. Outcomes included the Visual Analog Scale (VAS) scores, range of motion, radiographic parameters, union rates, and complications. A total of 18 patients were reviewed. Nine patients were included with an average of 19.4 months follow-up. Significant postoperative improvements were observed in VAS scores (P < .001), ankle plantarflexion (P = .04), talocalcaneal height (P = .03), and tibiotalar alignment (P = .02). All patients achieved a successful union of their subtalar and talonavicular joints arthrodesis. There was one reoperation for a persistent varus ankle deformity. This is the first study to evaluate the clinical outcomes, radiographic outcomes, and union rate in combined TATTR with hindfoot arthrodesis. The early results demonstrated significant clinical improvement with 100% hindfoot union rate and no prosthetic failure. IV.

Novel Treatment for a Completely Extruded Talus.

Department of Orthopedics, University of New Mexico School of Medicine, Albuquerque, NM.
Complete talar extrusion is a rare injury that is typically caused by high-energy impact. Treatment for a completely extruded talus is limited and has variable outcomes and complications. Tibiocalcaneal arthrodesis is one of the best treatments for restoring stability and reducing pain in the affected limb.

This case report presents a three-year follow-up of a young male with bilateral hindfoot fractures due to a high-energy road traffic accident, resulting in a comminuted open calcaneal fracture on the left and an open fracture-dislocation of the right talus. Staged reconstruction was performed, including initial debridement, temporary cement spacers, and subsequent fixation with femoral head allografts (FHAs). The right foot underwent a tibiotalocalcaneal (TTC) fusion, and the left foot received a double arthrodesis.

Background: Displaced intra-articular calcaneal fractures are a complication-ridden injury to treat and there are various treatment techniques to address this injury. The aim of this study was to evaluate the mid-term outcome of a percutaneous two-point distractor technique in patients with displaced intra-articular calcaneal fractures.
Methods: A retrospective data analysis of patients with intra-articular calcaneal fractures treated in a level 1 trauma center was conducted.

Introduction: Subtalar joint arthrodesis is primarily indicated for advanced osteoarthritis, hindfoot deformity, and/or instability. During the first 6-10 weeks after surgery, there is an intermediary structurally weaker state before complete bony fusion of the calcaneus and talus occurs. Loading of the foot can lead to mechanical stresses and relative movements in the former joint gap, which can impede the fusion process.

Background: Occupational exposure to high levels of noise increases the risk of noise-induced hearing loss (NIHL), resulting in significant long-term quality of life implications. Hearing protection is recommended if occupational noise exposure routinely exceeds 85 decibels (dB). The purpose of this study was to determine if foot and ankle surgeons are exposed to excessive levels of noise, thus putting them at an increased risk for NIHL.
