ICD-10: S43.13

The ICD-10 code S43.13 specifically refers to the dislocation of the acromioclavicular joint with a displacement greater than 200%. This condition is categorized under the broader classification of shoulder injuries and is significant due to the severity of the displacement involved.

Clinical Description

Anatomy and Function

The acromioclavicular (AC) joint is located at the junction of the acromion (the bony process on the scapula) and the clavicle (collarbone). This joint plays a crucial role in shoulder stability and mobility, allowing for a range of arm movements. Dislocations of the AC joint can occur due to trauma, such as falls or direct impacts, particularly in contact sports.

Dislocation Severity

A dislocation with greater than 200% displacement indicates a severe injury where the clavicle is significantly displaced from its normal position relative to the acromion. This level of displacement can lead to substantial pain, swelling, and loss of function in the shoulder. Patients may experience difficulty in raising their arm or performing overhead activities.

Symptoms

Common symptoms associated with S43.13 include:
- Severe pain at the site of the injury.
- Swelling and bruising around the shoulder.
- Deformity of the shoulder, often visible as a bump or protrusion where the clavicle is displaced.
- Limited range of motion in the shoulder joint.
- Tenderness upon palpation of the AC joint.

Diagnosis and Imaging

Diagnosis typically involves a physical examination and imaging studies. X-rays are the primary imaging modality used to confirm the dislocation and assess the degree of displacement. In some cases, a CT scan may be utilized for a more detailed evaluation of the joint and surrounding structures.

Treatment Options

Treatment for an AC joint dislocation, particularly with significant displacement, may vary based on the severity of the injury and the patient's activity level. Options include:

• Conservative Management: This may involve rest, ice application, immobilization with a sling, and physical therapy to restore function and strength.
• Surgical Intervention: In cases of severe displacement (greater than 200%), surgical repair may be necessary. This could involve the use of plates, screws, or other fixation devices to stabilize the joint and allow for proper healing.

Prognosis

The prognosis for patients with an S43.13 diagnosis largely depends on the treatment approach and the individual’s adherence to rehabilitation protocols. Many patients can return to normal activities, including sports, following appropriate treatment, although some may experience long-term effects such as arthritis or chronic pain.

In summary, the ICD-10 code S43.13 denotes a serious condition involving the dislocation of the acromioclavicular joint with significant displacement, necessitating careful diagnosis and management to ensure optimal recovery and function.
