S79.149
Salter-Harris Type IV physeal fracture of lower end of unspecified femur
Clinical Classification Guidelines
Medical Intelligence & Overview
A Salter-Harris Type IV physeal fracture involves a break across the growth plate, which is the area of developing tissue near the ends of long bones in children and adolescents. Specifically, the S79.149 code refers to a fracture at the lower end of an unspecified femur, affecting the growth plate. The femur, or thigh bone, is the longest bone in the body, and injuries to its growth plate can influence future bone growth and leg alignment. Detecting and treating this injury promptly is essential to prevent long-term complications, such as limb length discrepancies or deformities.
Causes & Symptoms
Clinical Causes: Sports injuries, such as high-impact falls or collisions Trauma from accidents, including car or pedestrian accidents Falls from heights, especially during childhood or adolescence Direct blow or impact to the thigh area Twisting injuries or sudden directional changes during physical activities
Key Symptoms: Severe pain localized at the lower end of the thigh or around the knee Swelling or tenderness in the affected area Limited range of motion in the knee or thigh Deformity or unnatural positioning of the leg Difficulty bearing weight or walking Possible bruising or discoloration around the injury site
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough physical examination followed by imaging studies. X-rays are the primary tool used to visualize the fracture and assess the involvement of the growth plate. In some cases, additional imaging such as MRI or CT scans may be required to evaluate the injury's extent and to plan appropriate treatment. Accurate identification of the fracture type and understanding its impact on the growth plate are crucial for effective management.
Treatment Protocols: Treatment options depend on the severity and location of the fracture. Common approaches include:
