Name of the Procedure:

Upper Extremity Addition, Test Socket, Wrist Disarticulation or Below Elbow (HCPCS L6680)

• Common Name: Test Socket for Wrist Disarticulation or Below Elbow Prosthesis
• Technical/Medical Terms: Upper extremity prosthetic fitting, test socket creation

Summary

This procedure involves fitting an initial test socket for patients who require a wrist disarticulation or below elbow prosthesis. The test socket is a prototype made to ensure that the final prosthesis fits correctly and comfortably.

Purpose

The procedure addresses limb loss due to trauma, disease, or congenital conditions affecting the wrist or lower arm. The goal is to create a custom-fit socket that will ensure the final prosthetic device functions optimally and is comfortable for the patient to wear.

Indications

• Amputees with wrist disarticulation or below elbow loss
• Patients needing a prosthetic limb post-surgery
• Individuals seeking to improve arm functionality and quality of life through a prosthetic device

Preparation

• No specific pre-procedure fasting or medication adjustments required.
• Initial assessments might include measurements of the residual limb and a review of the patient's medical history.
• The patient may need to undergo imaging (e.g., X-rays) and physical examinations.

Procedure Description

1. Initial Assessment: The healthcare provider measures the residual limb and evaluates the condition.
2. Cast Creation: A cast is made of the residual limb to replicate its shape.
3. Test Socket Fabrication: A test socket is created based on the cast, often using thermoplastic materials.
4. Fit Testing: The test socket is placed on the residual limb to assess comfort, fit, and alignment.
5. Adjustments: Necessary adjustments are made to ensure an optimal fit.
6. Final Evaluation: The fit and function are evaluated, and any further modifications are noted before creating the final prosthesis.

Tools and equipment include casting materials, thermoplastics, testing platforms, and measuring devices. Anesthesia or sedation is usually not required.

Duration

The procedure typically takes a few hours, including assessment, casting, and fitting.

Setting

The procedure is performed in an outpatient clinic or a specialized prosthetic fitting center.

Personnel

• Prosthetist (specialist in prosthetics)
• Occupational therapists may also be involved for functional assessment
• Support staff for assistance

Risks and Complications

• Mild discomfort during casting
• Potential skin irritation
• Adjustment issues requiring follow-up visits
• Rare risk of developing pressure sores if the fit is improper

Benefits

• Ensures that the final prosthesis fits well and functions effectively
• Helps in customizing the prosthesis for maximum comfort and usability
• Can lead to improved limb functionality and better quality of life

Recovery

• Minimal recovery time; patients can resume normal activities almost immediately
• Follow-up visits may be necessary to fine-tune the fit of the socket
• Instructions on how to care for the test socket and the residual limb

Alternatives

• Direct fitting of a final prosthesis without a test socket (riskier and less precise)
• Use of prefabricated prosthetic devices (may not provide optimal fit or comfort)

Pros: Test sockets ensure a custom fit, increased comfort, functionality, and reduced need for major adjustments in the final prosthesis. Cons: Additional time and visits required during the initial fitting process.

Patient Experience

Patients might feel mild discomfort during the casting process but generally experience little to no pain. They can expect detailed explanations and comfort measures from the healthcare team to ensure a smooth experience. Pain management is rarely needed, but patients are encouraged to communicate any discomfort for immediate adjustments.
