After a Colles fracture, what is a common complication of immobilization that should be monitored?

1. Decreased muscle mass

2. Increased pain perception

3. Joint stiffness

4. Skin integrity issues

The correct answer is: Joint stiffness

Following a Colles fracture, which commonly occurs in the distal radius due to a fall on an outstretched hand, immobilization in a cast or splint is essential for proper healing. However, this immobilization can lead to joint stiffness. Joint stiffness can arise from prolonged lack of movement in the affected area, which can affect not only the wrist but also the surrounding joints, such as those in the hand. When a joint is immobilized, the synovial fluid needed for lubrication may be reduced, and the surrounding soft tissues may shorten and tighten, resulting in decreased range of motion. To minimize the risk of joint stiffness after immobilization, it's important to begin gentle range of motion exercises as soon as it is safe to do so, following the guidelines provided by the healthcare provider. While decreased muscle mass, increased pain perception, and skin integrity issues are also potential concerns related to immobilization, joint stiffness is particularly significant in this context as it directly affects function and recovery following fractures, making the monitoring of joint motion an essential aspect of post-fracture rehabilitation.
