Subchondral bone cysts in the ankle: patient-specific finite element study data

Talbott, Harriet and Mengoni, Marlene (2022) Subchondral bone cysts in the ankle: patient-specific finite element study data. University of Leeds. [Dataset] https://doi.org/10.5518/1207

Dataset description

Data derived from finite element models of 18 haemophilic ankles to assess the statistical significance of subchondral bone cyst characteristics such as volume, depth, and location. Also included is a supplementary sensitivity study on the influence of subchondral bone cysts properties; and examples of stress redistribution with the addition of subchondral bone cysts presenting in the tibia alone, talus alone, and both tibia and talus.
