Lunotriquetral Ballottement Test / Shuck Test While most commonly the SL ligament and TFCC are affected in wrist ligament injuries, the wrist is a complex region and requires thorough assessment as missed ligament injuries may result in persistent pain, instability and reduced grip force and range of motion and could lead to, early, osteoarthritis. Prosser et al. in (2011) evaluated the Lunotriquetral Ballottement Test or Shuck Test on its diagnostic accuracy and report a positive likelihood rat

SULCUS SIGN FOR INFERIOR SHOULDER INSTABILITY With the Sulcus Sign, you are able to assess inferior shoulder instability. By longitudinal traction directly above the elbow, you will be able to (sub)luxate the patient's unstable shoulder and see a "sulcus" under the roof of the acromion, where the humeral head shoulder normally sits. P.S. There are no studies that have evaluated the tests' diagnostic accuracy to our knowledge | Physiotutors
