Description
Zachary Eatough and six colleagues used 3D imaging to compare ankle shapes in advanced varus osteoarthritis. In varus deformity the ankle tilts inward, and about half of patients compensate through the joint below. That compensation changes surgical planning. The team built a statistical shape model from weight-bearing CT scans. Seventy people took part: forty-four patients and twenty-six symptom-free controls. Six hindfoot bones were reconstructed for each person.
Patient-specific models let the researchers measure joint space, coverage, and fit at matching anatomical points. Principal components captured the main modes of shape variation. Comparing compensated and non-compensated ankles shows how the neighboring joint remodels to absorb misalignment. The twenty twenty-six work could help surgeons decide when a correction must address the compensating joint too.
