S72.434

Clinical Causes: Trauma from falls or direct blows to the knee or thigh Motor vehicle accidents Sports injuries involving twisting or direct impact High-impact falls, especially in older adults Pathological fractures due to weakened bones, such as from osteoporosis

Key Symptoms: Sudden pain in the inner part of the knee or thigh Swelling around the knee joint Tenderness when touching the area Limited ability to move or bear weight on the affected leg Possible bruising around the site of injury Feeling of instability or weakness in the knee

Diagnosis Path: The diagnosis involves a combination of physical examination and imaging tests. Medical professionals may assess for tenderness, swelling, and range of motion. X-rays are critical in confirming the presence of a fracture and determining whether it is displaced or nondisplaced. In some cases, MRI or CT scans might be used for detailed visualization, especially if other injuries are suspected or if the fracture's complexity requires further evaluation.

Treatment Protocols: Management of a nondisplaced fracture typically involves the following strategies: - **Rest and Immobilization:** Using a cast, brace, or bracing device to keep the femur stable and prevent movement that could worsen the fracture. - **Weight-bearing Restrictions:** Limiting or avoiding weight on the affected leg, often with crutches or walk aids. - **Pain Management:** Utilizing medications such as acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) to relieve discomfort. - **Monitoring:** Regular follow-up appointments to monitor healing via repeat X-rays. - **Physical Therapy:** Once healing has commenced, guided exercises to restore strength, stability, and range of motion. In some cases, surgery may be required if the fracture becomes displaced or if it is unstable, involving fixation with pins, screws, or plates to ensure correct alignment during healing.
