Statistical shape model of the talus bone morphology: A comparison between impinged and nonimpinged ankles.

Diagnosis of ankle impingement is performed primarily by clinical examination, whereas medical imaging is used for severity staging and treatment guidance. The association of impingement symptoms with regional three-dimensional (3D) bone shape variaties visible in medical images has not been systematically explored, nor do we know the type and magnitude of this relation. In this cross-sectional case-control study, we hypothesized that 3D talus bone shape could be used to quantitatively formulate the discriminating shape variations between ankles with impingement from ankles without impingement, and we aimed to characterize and quantify these variations.

Functional Outcomes and Quality of Life in Patients With Post-Traumatic Arthrosis Undergoing Open or Arthroscopic Talocrural Arthrodesis-A Retrospective Cohort With Prospective Follow-Up.

Fusion remains the gold standard for post-traumatic osteoarthritis after ankle fractures in many institutes. Patient-reported outcomes on long-term quality of life and functionality of talocrural arthrodesis remain relatively unknown. In literature, low patient numbers and inadequate outcome measures provide a poor foundation for patient expectation management.
