[Anatomy_13] Ulnotriquetral Ligament, Two Normal Perforation, prestyloid recess, pisotriquetral joint orifice

 

The ulnotriquetral ligament (UT) often has 2 normal perforations: a proximal opening to the prestyloid recess, and a distal pisotriquetral joint orifice.

(Left image) The prestyloid recess perforation is found just ulnar to the union between the proximal radioulnar ligament and the UT ligament.

(Right image) The pisotriquetral orifice is anterior to the proximal articular surface of the triquetrum and just distal to the prestyloid recess.
