Correct Answer: plaster of paris splint.
when treating fractures, especially a clean transverse fracture of the humerus mid-shaft like the one jeff experienced, the choice of immobilization device is crucial for effective healing. among the options provided, the plaster of paris splint is most commonly used for this type of injury.
plaster of paris has been a standard in fracture treatment for many years due to its ability to be molded to fit the shape of the injured limb precisely, ensuring the fracture remains immobilized. when applied, it hardens as it dries, forming a stiff cast that holds the broken bones in proper alignment. this rigidity is essential for the bones to heal in the correct position.
additionally, in recent times, synthetic materials have been introduced as an alternative to plaster of paris. these materials are favored for being lighter and typically waterproof, which can improve comfort and hygiene for the patient during the recovery period. however, plaster of paris remains widely used due to its accessibility and cost-effectiveness.
other options like internal fixation, compression sleeves, and crutches serve different purposes or support healing in different types of fractures. internal fixation involves surgical implementation of devices like screws and plates, which is more invasive and typically used for more complex fractures. compression sleeves are more for managing swelling than immobilizing a fracture. crutches can help in mobility but do not immobilize the fractured area.
therefore, for a straightforward mid-shaft humerus fracture, a plaster of paris splint is the appropriate choice. it provides the necessary immobilization, is cost-effective, and has a proven track record of facilitating effective healing in such cases.
