S79.142

Clinical Causes: Trauma or fall impacting the thigh or knee area Sports injuries or accidents involving direct blow to the lower thigh Motor vehicle accidents causing significant force to the leg Twisting or sudden twisting injuries to the femur Overuse injuries in active children or adolescents

Key Symptoms: Severe pain in the lower thigh or around the knee Swelling and tenderness in the affected area Bruising around the injury site Decreased movement or inability to bear weight on the leg Deformity or abnormal positioning of the leg or knee

Diagnosis Path: Diagnosis of a Salter-Harris Type IV fracture requires a clinical evaluation and imaging studies. The process includes: - Physical examination to assess for swelling, deformity, and mobility issues - X-ray imaging to visualize the fracture and determine its type and extent - Occasionally, additional imaging such as MRI or CT scan may be used for detailed assessment The key feature of a Type IV fracture is that it crosses through the growth plate and extends into the metaphysis and epiphysis, necessitating careful evaluation to prevent growth disturbances or deformities.

Treatment Protocols: Treatment approaches focus on realigning the fractured bone and promoting proper healing to minimize future growth problems. Common methods include: - Surgical intervention: Often required to realign the bones precisely through procedures such as internal fixation (pins, screws, plates) - Immobilization: Use of a cast or brace following surgery or when alignment is stable - Rest and restricted weight-bearing: To allow healing and reduce stress on the fracture site - Regular follow-up: Monitoring with X-rays to ensure proper healing and to detect any growth disturbances early In some cases, additional therapies like physical therapy may be recommended to restore strength and mobility after healing.
