Duration of wrist immobilization is associated with shoulder pain in patients with after wrist immobilization: an observational study.

The main goal of this study was to determinate the extent of the relationship between shoulder pain and time of wrist and thumb immobilization required after injury. One hundred twenty-three consecutive subjects presenting to the practice of different Orthopedic Specialist hospitals with a diagnosis of distal radius or scaphoid fracture that required wrist and thumb immobilization were screened for eligibility criteria. Upper extremity pain and the need for shoulder rehabilitation were assessed using the visual analogue scale (VAS) at baseline after immobilization period (T0) 1- and 3-month follow-up (1-FU/2-FU). More than 35% patients had shoulder pain (VAS>40 mm) after immobilization of the wrist. Shoulder pain intensity after immobilization and at follow-up (1 and 3 months) was strongly correlated with the duration of the immobilization. Immobilization for 3.5 weeks or longer was the strongest predictor for the need of subsequent shoulder rehabilitation. An increased the time of immobilization of the wrist is associated with an increase in shoulder pain and need for shoulder rehabilitation in patients after wrist fracture.
