M76.821

Clinical Causes: Overuse or repetitive stress from activities such as running, walking, or jumping Increased body weight leading to added pressure on the ankle and foot Sudden or excessive increase in physical activity or intensity Trauma or injury to the inside of the ankle Structural abnormalities like flat feet or overpronation, which put strain on the tendon Degenerative changes related to aging or chronic tendinitis

Key Symptoms: Pain along the inside of the ankle and the arch of the foot, which may worsen with activity Swelling and tenderness around the inner ankle Difficulty walking or standing, especially after prolonged activity A feeling of weakness or instability in the affected foot Possible flattening of the foot's arch over time Pain may radiate along the course of the posterior tibial tendon

Diagnosis Path: To diagnose posterior tibial tendinitis, healthcare providers typically conduct a physical examination to assess tenderness, swelling, and the foot's alignment. They may ask about activity levels and recent injuries. Diagnostic imaging tests such as X-rays can help rule out other conditions and assess bone structure, while MRI scans may be used to evaluate the extent of tendon inflammation or damage, providing detailed images of soft tissues. Proper diagnosis is important in developing an effective treatment plan.

Treatment Protocols: Managing posterior tibial tendinitis involves a combination of strategies aimed at reducing inflammation, relieving pain, and supporting healing. Common treatments include: - Rest and activity modification to prevent further stress on the tendon - Ice application to decrease swelling and discomfort - Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation - Orthotic devices such as arch supports or custom insoles to correct structural abnormalities and alleviate strain - Physical therapy focused on strengthening foot and ankle muscles, improving flexibility, and correcting gait - Use of ankle braces or compression wraps to provide support - In severe cases, immobilization with a cast or walking boot, or surgical intervention may be necessary to repair or reconstruct the damaged tendon Prompt management can help prevent the progression to chronic tendinitis or other complications, emphasizing the importance of early consultation with healthcare providers.
