Traction Shift Subluxation Relocation Test | CMC 1 Osteoarthritis

In this video I'm going to demonstrate the traction shift or subluxation relocation test for carpometacarpal osteoarthritis.
Thumb osteoarthritis is a painful and debilitating condition that affects a large proportion of the adult population with radiographic prevalence reaching 90 percent in both men and women by the age of 80.
Qualitative assessment of the history physical examination and radiographs is used to diagnose and treat thumb CMC arthritis.
The test is done using a single-handed technique. The examiner applies longitudinal traction to the thumb and then alternates dorsal and palmar pressure over the basis of the metacarpal to provoke subluxation and then relocation of the joint.
The test is considered positive if it elicits pain within the joint.
