A Marsh fracture is a type of fracture that occurs in the neck of the scapula (shoulder blade), specifically at the junction of the acromial and glenoid fossae. This fracture is named after the British surgeon Sir Robert Jones's student, John Marsh, who first described it in 1904. Marsh fractures are relatively rare and typically result from high-energy trauma, such as a fall from a height or a motor vehicle accident. Symptoms may include pain, swelling, and limited shoulder mobility. Treatment may involve immobilization, surgery, or physical therapy, depending on the severity and location of the fracture.
