M67.01

Short Achilles tendon (acquired), right ankle

Clinical Classification Guidelines

Medical Intelligence & Overview

A shortened Achilles tendon, particularly when acquired, can significantly impact ankle function and mobility. The Achilles tendon is a strong band of tissue that connects the calf muscles to the heel bone, enabling activities like walking, running, and jumping. When this tendon becomes shorter than normal—a condition known as a short Achilles tendon—it can cause discomfort, difficulty in movement, and limitations in physical activity, especially at the right ankle. This condition may develop over time due to injury, inactivity, or other health issues, and typically requires diagnosis and management by healthcare professionals.

Causes & Symptoms

Clinical Causes: Previous injury or trauma to the Achilles tendon that results in scarring and shortening Prolonged periods of immobilization or disuse of the ankle and foot Chronic inflammation or tendinitis leading to tissue changes and shortening Congenital conditions that present with a naturally shorter Achilles tendon Age-related degenerative changes in tendon tissue Poor stretching or failure to perform proper warm-up exercises before physical activity

Key Symptoms: Tightness or stiffness in the back of the ankle or calf Reduced flexibility in the Achilles tendon, making ankle movements difficult Pain or discomfort especially during walking or stretching the ankle Limited ability to perform activities that require ankle extension or plantarflexion A visible or palpable thickening or fibrosis along the Achilles tendon Potential gait abnormalities due to restricted ankle motion

Diagnostic & Treatment

Diagnosis Path: Diagnosis involves a thorough clinical evaluation by a healthcare provider, including a physical examination to assess ankle flexibility, strength, and movement. Imaging studies such as ultrasound or magnetic resonance imaging (MRI) may be employed to confirm tendon shortening, evaluate tissue quality, and rule out other related conditions. The healthcare professional may also review the patient’s medical history, activity levels, and any previous ankle injuries.

Treatment Protocols: Management of a short Achilles tendon often includes a combination of therapies aimed at improving flexibility and function. These may involve:
