Radial Head Fractures: Types, Causes, and Treatment Options 요골두 골절: 유형, 원인 및 치료 방법

Radial head fractures are a common type of elbow fracture. The radial head is the part of the radius bone near the elbow that forms a joint with the humerus (upper arm bone). This fracture usually occurs from a fall on an outstretched hand (FOOSH injury) or a direct blow to the elbow. Types: Radial head fractures are typically classified using the Mason system: 1. Type I (Mason I): These are nondisplaced or minimally displaced fractures. They often involve less than 2mm of displacement and no mechanical block to motion. 2. Type II (Mason II): These fractures are displaced, involving more than 2mm of displacement, or angulated. They might cause a mechanical block to motion. 3. Type III (Mason III): These are comminuted fractures, meaning the bone has broken into multiple pieces, which often leads to instability of the joint. 4. Type IV (Mason IV): These are fractures associated with an elbow dislocation or other injuries, which can significantly affect joint stability and function. Treatments: The choice of treatment depends on the type of fracture, patient characteristics, and the presence of any associated injuries: 1. Conservative treatment: This is often used for Type I fractures. It includes pain management, rest, ice, and immobilization of the elbow for a short period, followed by early range of motion exercises to prevent stiffness. 2. Surgery: This is typically used for Type II, III, and IV fractures that are displaced or unstable. The exact procedure can vary: Open reduction and internal fixation (ORIF): The surgeon puts the pieces of bone back in the correct position (open reduction) and then uses hardware like screws and plates to hold them in place (internal fixation). Radial head resection: In some cases, the damaged part of the radial head is removed, but this can lead to instability. Radial head arthroplasty: If the fracture is severely comminuted and not amenable to repair, replacement of the radial head with a prosthetic implant may be considered. 3. Rehabilitation: Physical therapy is a critical part of treatment, whether the patient has surgery or not. It helps to restore range of motion, strength, and function of the elbow.
