Examination of the scapholunate gap, starting at Lister’s tubercle.
Stability of joint functions
Joint stability is assessed by way of a manual examination carried out by a duly trained professional.
Manual provocation testing
Required material: None
Procedure: In the case of suspicion that a joint is instable, the examiner will carry out an examination to test the stability. This can be a specified test or an examination from manual therapy. The type of test carried out and the presence of any degradation of the joint stability is recorded.
The following videos illustrate currently practised tests of stability:
Dorso-palmar translational movements are carried out.
Instability in the scapholunate joint is displayed in comparison to the other side.
The patient’s hand is put into an ulnar position.
The examiner’s thumbs apply pressure to the distal flexor side of the scaphoid pole. The index finger is positioned on the extensor side at the level of the proximal scaphoid pole.
The patient’s hand is passively moved radially from the ulnar position.
A positive test results in a palpable radial click phenomenon and in pain in the extensor side at the level of the proximal scaphoid pole due to subluxation of the scaphoid over the dorsal radius.
