Posterior tibial tendinitis, unspecified leg
Clinical Classification Guidelines
Medical Intelligence & Overview
Posterior tibial tendinitis is an inflammation or irritation of the posterior tibial tendon, which runs along the inside of the ankle and helps support the arch of the foot. This condition can cause pain, swelling, and difficulty in walking and standing. It commonly affects adults, especially those involved in activities that place repetitive stress on the foot and ankle. Recognizing the signs and understanding the causes and treatment options can help manage symptoms effectively.
Causes & Symptoms
Clinical Causes: Overuse or repetitive stress on the posterior tibial tendon from activities like running, jumping, or prolonged standing Increased physical activity without proper conditioning or warm-up Flat feet or fallen arches, which place additional strain on the tendon Trauma or ankle injuries that lead to inflammation Obesity, contributing to increased stress on the foot and ankle structures Aging, reducing the tendon's ability to withstand stress Certain footwear that lacks proper arch support
Key Symptoms: Pain along the inside of the ankle and foot, which may worsen with activity Swelling or tenderness over the course of the posterior tibial tendon Difficulty walking or standing for long periods Flattening of the arch of the foot over time A feeling of instability or weakness in the ankle Pain that may decrease with rest but worsens during activity Potential development of bunions or deformities in advanced cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis is typically made through a combination of physical examination and imaging tests. A healthcare provider will assess pain points, swelling, and foot alignment. Imaging studies such as ultrasound or MRI can provide detailed views of the tendon to confirm inflammation or tears and rule out other conditions.
Treatment Protocols: Management of posterior tibial tendinitis involves both conservative and, in severe cases, surgical approaches. Common treatments include:
