M76.82

Clinical Causes: Overuse or repetitive stress from activities such as running, jumping, or walking long distances. Sudden increase in physical activity intensity or duration. Flat feet or overpronation, which puts extra strain on the posterior tibial tendon. Trauma or ankle injuries that involve stretching or tearing of the tendon. Degeneration of the tendon due to aging or chronic stress. Obesity, which increases load on the ankle and foot structures.

Key Symptoms: Pain along the inside of the ankle and arch, worsening with activity. Swelling and tenderness around the posterior tibial tendon. Flattening of the arch over time. Difficulty standing on tiptoe or walking long distances. Instability or a feeling of the ankle giving way. Possible redness or warmth in the affected area In some cases, pain may radiate into the heel or along the inner side of the foot.

Diagnosis Path: Healthcare providers typically diagnose posterior tibial tendinitis through a combination of physical examination and patient history. They assess for tenderness along the tendon, swelling, and deformities. Imaging studies such as X-rays can help rule out bone issues and assess foot structure, while MRI scans provide detailed images of soft tissues to confirm inflammation or tears in the tendon. The clinician may also evaluate foot biomechanics to identify contributing factors like overpronation.

Treatment Protocols: Managing posterior tibial tendinitis involves a multifaceted approach aiming to reduce inflammation, alleviate symptoms, and address underlying causes. Typical treatment options include: - Rest and activity modification to prevent further strain. - Ice application to reduce swelling and pain. - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief. - Use of supportive devices such as orthotic inserts to correct foot mechanics. - Physical therapy focusing on strengthening exercises and stretching routines. - Immobilization with a brace or walking boot in severe cases. - Gradual return to activity once symptoms improve. - In chronic or severe cases, surgical intervention may be considered to repair or debride the damaged tendon. Preventive measures involve maintaining a healthy weight, wearing proper footwear, and incorporating foot and ankle strengthening exercises into regular fitness routines.
