S82.855

Clinical Causes: Falls from height onto the ankle Sports injuries involving twisting or direct impact Motor vehicle accidents Twisting or rolling the ankle during physical activity Accidental missteps that apply excessive force to the ankle

Key Symptoms: Pain and tenderness around the ankle joint Swelling and bruising around the ankle Difficulty bearing weight or walking Deformity or abnormal positioning of the ankle (less common in nondisplaced fractures) Stiffness and limited range of motion in the ankle A sensation of ankle instability or weakness

Diagnosis Path: Diagnosis usually involves a clinical examination and imaging tests. Healthcare providers assess the ankle for swelling, deformity, tenderness, and range of motion. X-rays are the primary imaging tool used to confirm the presence of a fracture and determine if the bones are displaced or nondisplaced. In some cases, additional imaging like CT scans may be employed for detailed assessment, especially if the fracture involves complex or multiple fragment patterns.

Treatment Protocols: Management of a nondisplaced trimalleolar fracture generally involves conservative approaches, but surgical intervention may be necessary if instability is noted. Treatment options include: - Immobilization with a cast or brace to keep the ankle stable during healing - Rest and elevation to reduce swelling - Application of ice packs to ease pain and control swelling - Pain management with medications as recommended by a healthcare provider - Limited weight-bearing activities, sometimes requiring crutches or a walker - Close monitoring through follow-up appointments In cases where the fracture is displaced or the ankle remains unstable, surgical procedures such as internal fixation with screws and plates are employed to realign the bones and ensure proper healing. Physical therapy may be prescribed after immobilization to restore strength and mobility.
