Linscheid Squeeze Test
Purpose
This test is used to detect ligamentous instability of the second and third carpometacarpal joints. [1] It's also known as the Linscheid Compression Test or Squeeze Test. This is a clinical test used to assess the integrity of the triangular fibrocartilage complex (TFCC) and the lunotriquetral (LT) joint in the wrist.It is also used in examination of the Wrist: Ulnar-Sided Wrist Pain Due to Ligamentous Injury[2]
Technique
The starting position of the patient for the test is sitting position and then the examiner supports the metacarpal shafts with one hand. With the other hand, the examiner pushes the metacarpal heads dorsally, then palmarly. Pain localized to the second or third carpometacarpal joints makes this maneuver result considered positive.[1]
Evidence
There is no current evidence on the reliability, validity, sensitivity or specificity of this test. It was referenced in a case study of a climber with left wrist pain from a forceful ulnar deviation. It was referenced as a commonly used stress test for ruling out wrist injuries[4]. It was also referenced that provocative maneuvers to assess instability are not as effective at prediction the presence of injury versus the absence of injury.
