B. Hindfoot Arthritis

Subtalar Arthritis

Diagnose isolated subtalar arthritis (causes: trauma, subtalar coalition, inflammatory). Detail non-operative care. Master techniques for subtalar arthrodesis (posterior/lateral approach, fixation with screws/plates).

Triple-Joint Arthritis

Define triple arthrodesis (fusion of subtalar, talonavicular, and calcaneocuboid joints). Understand indications (severe deformity, pan-hindfoot arthritis) and goal of creating a plantigrade foot. Review specific challenges with bony apposition and fixation.

Talus Osteochondral Lesions (OCLs)

Staging systems (Berndt & Harty, Ferkel & Cheng). Primary treatment strategies: Retrograde vs. Anterograde drilling, microfracture/nanofracture techniques. Secondary/Salvage procedures: Osteochondral Autograft Transfer System (OATS), Autologous Chondrocyte Implantation (ACI), and associated bone grafting techniques for cyst treatment.
