Final answer:
A 3 part proximal humeral fracture is when the upper part of the humerus bone breaks into three separate pieces. It typically happens as a result of a fall or direct blow to the arm. Treatment involves immobilization or surgery, with rehabilitation exercises to regain strength and motion.
Step-by-step explanation:
A 3 part proximal humeral fracture refers to a fracture that occurs in the proximal (upper) part of the humerus bone in three separate pieces. This type of fracture typically happens as a result of a fall or direct blow to the arm.
One example of a 3 part proximal humeral fracture is when the humeral head (the rounded part at the top of the bone) is separated into three fragments.
Treatment for a 3 part proximal humeral fracture usually involves immobilization or surgery depending on the severity of the fracture. Rehabilitation exercises may also be prescribed to regain strength and range of motion.
