S49.13
Salter-Harris Type III physeal fracture of lower end of humerus
Clinical Classification Guidelines
Medical Intelligence & Overview
A Salter-Harris Type III physeal fracture of the lower end of the humerus involves a specific type of growth plate injury in the upper arm bone near the elbow. This kind of fracture occurs through the growth plate and extends into the surrounding bone, which can affect future bone growth if not properly treated. It typically happens in children and adolescents, as their bones are still growing. Recognizing and managing this fracture is critical for normal arm function and growth.
Causes & Symptoms
Clinical Causes: Trauma from falls onto an outstretched arm Sports injuries, especially during activities involving falls or direct blows Motor vehicle accidents causing impact to the arm Direct blow or trauma to the elbow area Twisting injuries during physical activities
Key Symptoms: Pain in the elbow or lower humerus area Swelling around the elbow joint Tenderness when touching the affected area Limited range of motion in the arm or elbow Deformity or abnormal positioning of the arm Bruising or discoloration around the injury site Difficulty moving the arm or elbow, especially during activities
Diagnostic & Treatment
Diagnosis Path: Diagnosis begins with a detailed medical history and physical examination. The healthcare provider will assess for visible deformity, swelling, pain, and range of motion. Imaging studies are crucial — X-rays of the elbow and upper arm from different angles help confirm the specific type and extent of the fracture, including whether the growth plate is involved and if the fracture extends into the joint. In some cases, additional imaging such as MRI or CT scans may be necessary to evaluate the injury thoroughly.
Treatment Protocols: Treatment options depend on the severity and specifics of the fracture. Common approaches include: - **Immobilization**: Using a cast or splint to keep the arm stable and allow the fracture to heal, especially if the fracture is displaced but can be realigned without surgery. - **Closed reduction**: In cases of significant displacement, the bones may need to be manually realigned under anesthesia without extensive surgical intervention. - **Surgical intervention**: For severely displaced fractures or those involving the joint, surgery may be required to realign the bones precisely using pins, screws, or plates. - **Rehabilitation**: After the fracture has healed, physical therapy is often necessary to restore strength, flexibility, and function of the arm. Long-term monitoring is essential, especially because growth plate injuries can impact future bone growth and development. Follow-up appointments typically include repeat X-rays to ensure proper healing and growth.
