  • The study provides macroanatomical reference data for wildlife veterinary surgery on injured lynxes but lacks validation through surgical outcome data. Clinical correlation studies documenting musculoskeletal injury patterns, surgical repair techniques, and healing outcomes in wild Caucasian lynx would validate the clinical utility of these anatomical descriptions.

    A Macroanatomical Study on the Hind Leg Muscles and Tendons of the Caucasian Lynx · 2026 · DOI

  • The gluteofemoral muscle origin and insertion were found similar to Eurasian lynx, but the study lacks comparative data on muscle mass, attachment site angles, and functional lever arms across the Lynx genus (L. canadensis, L. pardinus, L. rufus). Quantitative 3D morphometric analysis would elucidate genus-level variation in hip and stifle extensor muscle patterns.
