  • Radial Head Fracture Repair and Rehabilitation
    1 Radial Head Fracture Repair and Rehabilitation Surgical Indications and Considerations Anatomical Considerations: The elbow is a complex joint due to its intricate functional anatomy. The ulna, radius and humerus articulate in such a way as to form four distinctive joints. Surrounding the osseous structures are the ulnar collateral ligament complex, the lateral collateral ligament complex and the joint capsule. Four main muscle groups provide movement: the elbow flexors, the elbow extensors, the flexor-pronator group, and the extensor-supinator groups. Different types of radial head fractures can occur each of which has separate surgical indications and considerations. Fractures of the proximal one-third of the radius normally occur in the head region in adults and in neck region in children. The most recognized and used standard for assessing radial head fractures is the 4-part Mason classification system. It is used for both treatment and prognosis. Classification: Type I fracture A fissure or marginal fracture without displacement. Type II fracture Marginal fractures with displacement involving greater than 2 mm displacement. Type III fracture Comminuted fractures of the whole radial head. Type IV fracture (variation) A comminuted fracture, with an associated dislocation, ligament injury, coronoid fracture, or Monteggia lesion. Pathogenesis: Severe comminuted fractures or fracture dislocations of the head of the radius often occur as the result of a fall on an outstretched arm with the distal forearm angled laterally, or a valgus stress on the elbow. Fractures can also occur from a direct blow or force to the elbow (e.g. MVA). Chronic synovitis and mild deterioration of the articular surfaces associated with arthritis (e.g.

Please speak to the Virtual Fracture Clinic who can advise you Radial Head A5 leaflet 18 1035 bak.indd 1 19/03/2018 14:02:36 This information leaflet follows up your recent conversation with the Virtual Fracture Clinic, where your case was reviewed by an orthopaedic Consultant (Bone specialist). You have a break in the radial head (neck), which is one of the bones in your elbow. These fractures almost always heal well given time and movement. A sling has been provided for your comfort and should only be used for a few days. Movement is important to allow the fracture to heal and the elbow not to stiffen. The movement exercises below will help relieve some of the pain as well as helping you to recover well from your injury. Start these as soon as you are able. It is very important to keep moving the elbow gently and to gradually get back to normal daily activities within the limits of pain. There is however a risk that by forcibly stretching you may experience pain & delay your recovery. Painkillers are important to aid your recovery. Healing: This normally takes approximately 6 weeks to heal. Pain and swelling: Take regular over-the-counter analgesia (painkillers) until pain settles. To stop non-steroidal anti-inflammatory drugs (NSAIDS) e.g. Ibuprofen after 5-7 days as this will slow bone healing.
