S49.149
Salter-Harris Type IV physeal fracture of lower end of humerus, unspecified arm
Clinical Classification Guidelines
Medical Intelligence & Overview
A Salter-Harris Type IV physeal fracture involves a break across the growth plate (physis), the end of a long bone that is responsible for growth in children and adolescents. Specifically, this injury occurs at the lower end of the humerus, the bone of the upper arm. Such fractures are significant because they can affect future bone growth and may lead to deformity if not properly treated. The ICD-10 code S49.149 categorizes this particular injury when the exact arm (left or right) is unspecified.
Causes & Symptoms
Clinical Causes: Direct trauma or blow to the elbow or upper arm area Falls onto an outstretched hand with arm extended Sports injuries involving trauma to the elbow Motor vehicle accidents causing impact to the arm Crush injuries or accidents involving heavy object impact
Key Symptoms: Severe pain around the elbow or upper arm Swelling and tenderness at the lower end of the humerus Decreased range of motion or inability to move the arm Deformity or visible misalignment of the elbow Possible bruising around the injury site Numbness or tingling if nerves are affected
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough physical examination followed by imaging studies. X-rays are essential to visualize the fracture, assess its severity, and determine if it crosses the growth plate. In some cases, additional imaging like MRI or CT scans may be used to evaluate soft tissue involvement or complex fracture patterns. Radiologists look for the characteristic features of a Salter-Harris Type IV fracture, which crosses the metaphysis, growth plate, and epiphysis, often requiring careful interpretation.
Treatment Protocols: Management usually involves surgical intervention or conservative approaches depending on fracture displacement and stability. For displaced fractures, procedures might include open reduction and internal fixation with pins, screws, or plates to realign the bones properly. Non-displaced fractures may be monitored with immobilization using casts or splints. Early diagnosis and appropriate treatment are important to reduce the risk of growth disturbances, deformities, or joint issues. Rehabilitation and physical therapy are often part of recovery to restore strength and mobility.
