Upper extremity injuries should be splinted with the hand:

When managing upper extremity injuries, splinting is essential to stabilize the affected area and alleviate pain while preventing further injury. The correct approach involves positioning the hand in the position of function, which maintains the hand and wrist in a natural, relaxed posture. This position allows for proper circulation and nerve function, promoting recovery while minimizing discomfort.

Injuries to the upper extremities often involve fractures or dislocations, and maintaining this functional position ensures that the tendons and ligaments are not overly stretched or compressed. It also prepares the injured area for future rehabilitation and mobilization, as the natural function of muscles and joints is preserved.

Positioning the hand higher than the heart or across the chest can interfere with circulation and comfort and may not offer the necessary support. Having the palm up could also lead to complications with the splinting process, as it might not provide adequate immobilization required for healing. Ensuring the hand is splinted correctly in the position of function promotes the best outcome in treating upper extremity injuries.
