The trochanter tertius in a dog

Summary

The tuberositas glutaea is a rudimentary structure in the dog’s os femoris. It gives attachment to the superficial gluteal muscle, and is known by veterinary anatomists and orthopedic surgeons as trochanter tertius. We report an atypical eminence exposed through a surgical approach on a Cane Corso Dog. Anatomic and radiographic investigations led us to recognize this eminence as an abnormally grown tuberositas glutaea.

Zusammenfassung

Die Tuberositas glutaea des Os femoris ist eine rudimentär entwickelte Struktur beim Hund. Da sie als Ansatz der oberflächlichen Gesäßmuskulatur (Musculus gluteus superficialis) dient, ist er den Veterinäranatomen und orthopädischen Chirurgen als Trochanter tertius bekannt. Wir berichten über eine atypische Auftreibung des Os femoris, die durch chirurgischen Zugang bei einem Hund der Rasse Cane Corso freigelegt wurde. Diese Auftreibung konnte durch anatomische sowie radiologische Untersuchungen als abnormale Ausprägung des Tuberositas glutaea interpretiert werden.
