Final answer:
A thumb spica splint is recommended for a distal radius/wrist fracture as it immobilizes the thumb and wrist, ensuring proper healing. Surgery may be required if a splint is inadequate for stabilization or in the case of a displaced fracture.
Step-by-step explanation:
For a distal radius/wrist fracture, such as a Colles fracture, a thumb spica splint should be applied. This type of splint extends from the forearm to the hand, immobilizing the thumb and wrist to facilitate proper healing. The thumb spica splint is particularly important as it maintains the thumb in a functional position, which is critical for grip and hand function. When this type of fracture involves the radiocarpal joint surface, issues like decreased range of motion, disrupted joint alignment, and potential long-term complications like arthritis can occur.
If a standard splint does not stabilize the fracture adequately or if the bone is displaced, surgery may be required. Surgical intervention would typically involve the realignment of the bone, potentially using hardware such as pins, plates, or screws to maintain the correct position during healing.
