S82.66

Clinical Causes: Twisting the ankle abruptly, such as during sports or falls Direct blow or impact to the outer ankle Accidental trauma, such as slipping on ice or uneven surfaces High-impact sports activities Stress fractures from overuse or repetitive motion

Key Symptoms: Pain around the outer ankle, especially after injury Swelling and tenderness on the outside of the ankle Bruising in the affected area Difficulty bearing weight or walking Stiffness and limited movement in the ankle Possible deformity or abnormal positioning in severe cases, though less common with nondisplaced fractures

Diagnosis Path: Diagnosis generally involves a medical history review and physical examination. To confirm the presence and nature of the fracture, imaging tests such as X-rays are typically performed. These images help determine whether the fracture is displaced or nondisplaced and guide treatment planning. Additional imaging like MRI or CT scans may be needed in complex cases or when the injury is unclear.

Treatment Protocols: The primary goal in treating a nondisplaced fracture of the lateral malleolus is to ensure proper healing while minimizing complications. Treatment options include: - Rest and immobilization: Avoid weight-bearing activities, and use crutches if necessary. - Immobilization: A cast or a walking boot may be applied to keep the ankle stable while healing. - Elevation and ice: To reduce swelling and relieve pain. - Pain management: Over-the-counter medications such as acetaminophen or NSAIDs can be used under medical guidance. - Gradual mobilization: Once healing progresses, physical therapy might be recommended to restore strength and range of motion. In cases where there's instability or risk of displacement, surgical intervention might be considered to realign the fracture and secure it with hardware. However, for nondisplaced fractures, conservative management often suffices, leading to good recovery outcomes.
