S72.455

Clinical Causes: Fall directly onto the knee or lower thigh Trauma from vehicle accidents sports injuries involving direct impact or twisting forces Osteoporotic fractures in older adults due to weakened bones Falls from height that apply force to the distal thigh

Key Symptoms: Localized pain around the lower thigh or knee Swelling or bruising in the region Tenderness when touching the area Difficulty bearing weight or walking Limited range of motion at the knee joint Possible deformity or misalignment, although less common in nondisplaced fractures

Diagnosis Path: Diagnosis typically involves a thorough physical examination and imaging tests. An X-ray provides clear visualization of the femur to identify the fracture's location and whether it is displaced or nondisplaced. Sometimes, additional imaging like MRI or CT scans may be ordered if detailed assessment is necessary, particularly when other soft tissue injuries are suspected. Healthcare providers assess the injury's stability and the surrounding tissue condition to plan appropriate treatment.

Treatment Protocols: Treatment options aim to restore the femur's proper alignment and promote healing. For nondisplaced fractures, conservative management is often sufficient and includes: - **Immobilization:** Using a cast, brace, or splint to immobilize the thigh and knee, maintaining bone stability during healing. - **Rest and activity modification:** Limiting weight-bearing activities and avoiding putting stress on the affected limb. - **Pain management:** Over-the-counter medications or prescribed analgesics to alleviate discomfort. In some cases, especially if there's concern about potential displacement or stability, surgical intervention may be necessary. Surgery usually involves the use of internal fixation devices such as screws or rods to secure the bones until healing occurs. Post-treatment, physical therapy may be recommended to regain strength and mobility, depending on recovery progress.
