ICD-10: M66.311

The ICD-10 code M66.311 refers specifically to the spontaneous rupture of flexor tendons in the right shoulder. This condition is categorized under the broader classification of spontaneous ruptures of synovium and tendon, which are often associated with various underlying factors, including degenerative changes, trauma, or systemic diseases.

Clinical Description

Definition

A spontaneous rupture of flexor tendons occurs when one or more of the tendons that flex the shoulder joint tear without any significant external trauma. This can lead to pain, loss of function, and weakness in the affected shoulder.

Symptoms

Patients with a spontaneous rupture of flexor tendons may experience:
- Sudden pain in the shoulder area, often described as sharp or severe.
- Swelling and tenderness around the shoulder joint.
- Limited range of motion, making it difficult to perform daily activities.
- Weakness in the shoulder, particularly when attempting to flex the arm.

Risk Factors

Several factors may contribute to the risk of spontaneous tendon rupture, including:
- Age: Tendons may weaken with age, increasing the likelihood of rupture.
- Chronic conditions: Diseases such as diabetes or rheumatoid arthritis can affect tendon integrity.
- Overuse: Repetitive motions or overexertion can lead to tendon degeneration.

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical evaluation, including:
- Patient history: Understanding the onset of symptoms and any previous shoulder issues.
- Physical examination: Assessing pain, swelling, and range of motion in the shoulder.

Imaging Studies

Imaging techniques may be employed to confirm the diagnosis:
- Ultrasound: Useful for visualizing soft tissue structures and assessing tendon integrity.
- MRI: Provides detailed images of the shoulder's soft tissues, helping to identify the extent of the rupture.

Treatment Options

Conservative Management

Initial treatment often involves conservative measures:
