S79.131

Clinical Causes: Trauma from falls or sports injuries Motor vehicle accidents Direct blows to the knee or thigh High-impact sports activities Accidental injuries during play or other physical activities

Key Symptoms: Severe pain in the knee or thigh area Swelling around the lower end of the thigh Difficulty moving or bearing weight on the affected leg Tenderness to touch at the injury site Deformity or misalignment of the knee joint Limited range of motion in the knee Possible bruising around the area

Diagnosis Path: Diagnosing a Salter-Harris Type III fracture involves a combination of physical examination and imaging studies. The healthcare provider will check for swelling, deformity, and tenderness, and will assess movement. X-rays are the primary diagnostic tool used to confirm the presence and extent of the fracture, accurately locating the break across the growth plate and into the epiphysis. Advanced imaging like MRI or CT scans may sometimes be used for detailed assessment, especially if the fracture is complex or not clearly visible on X-rays.

Treatment Protocols: Treatment of a Salter-Harris Type III fracture focuses on realigning the fractured bone to promote proper healing and growth. Approaches include: - **Immobilization:** Using a cast or brace to keep the fracture in place during healing. - **Surgical intervention:** In some cases, especially with displaced fractures, surgery may be necessary to realign the bone fragments and secure them with pins, screws, or plates. - **Rest and activity restriction:** Limiting weight-bearing and strenuous activities to prevent displacement. - **Pain management:** Use of medications to control pain and reduce inflammation. - **Rehabilitation:** Physical therapy may be recommended post-healing to restore strength and mobility. Close follow-up with healthcare providers is essential to monitor healing and growth, minimizing the risk of growth disturbances or joint problems later in life.
