Name of the Procedure:

Addition to Upper Extremity Prosthesis, Below Elbow/Above Elbow, Lock Mechanism (Excludes Socket Insert)

• Common Names: Prosthetic Lock Mechanism Addition
• Technical Term: HCPCS Code L6698

Summary

This procedure involves adding a locking mechanism to an upper extremity prosthesis for patients who have lost part of their arm either below or above the elbow. The locking mechanism enhances the functionality and stability of the prosthetic arm.

Purpose

• Addressed Conditions: This procedure is primarily aimed at patients who have undergone an amputation below or above the elbow and require a prosthetic arm for daily functioning.
• Goals/Outcomes: The addition of a lock mechanism significantly improves the prosthesis' versatility, making it easier for the user to perform tasks. Expected outcomes include better control and more natural movement of the replacement limb.

Indications

• Symptoms/Conditions: Loss of limb below or above the elbow.
• Patient Criteria: Suitable for patients who need improved functionality in their upper extremity prosthesis and do not have contraindications for the use of a locking mechanism.

Preparation

• Pre-Procedure Instructions: Patients should follow specific instructions from their healthcare provider, which may include fasting or adjusting current medications.
• Diagnostic Tests: A thorough assessment of the remaining limb's strength and coordination may be necessary.

Procedure Description

1. Initial Consultation: Evaluating the patient's current prosthesis and determining the necessity for a lock mechanism.
2. Customization: The lock mechanism is custom-fitted to the existing prosthesis by a prosthetist.
3. Adjustment and Calibration: Ensuring the lock mechanism correctly aligns and integrates with the prosthetic limb.
   • Tools/Equipment: Specialized prosthetic tools and the lock mechanism.
   • Anesthesia: Not typically required for this non-surgical addition.

Duration

The procedure generally takes about 1-2 hours, including adjustments and initial fitting sessions.

Setting

This procedure is typically performed in a prosthetics and orthotics clinic or healthcare facility specialized in limb prosthesis.

Personnel

• Healthcare Professionals: Registered prosthetists and orthotists, physical therapists, and prosthetic technicians.

Risks and Complications

• Common Risks: Mild discomfort during adjustment, initial difficulty in adapting to the new mechanism.
• Rare Risks: Potential misalignment of the mechanism, minor irritation at the site of the prosthesis attachment. These issues are usually manageable with further adjustments or modifications.

Benefits

• Expected Benefits: Improved function and ease of use of the prosthetic arm, allowing for more natural movements and better stability.
• Realization Time: Benefits can be noticed immediately after installation, with significant improvements typically observed within a few days to weeks as the patient adapts.

Recovery

• Post-Procedure Care: Regular follow-up appointments to monitor and adjust the mechanism if needed.
• Expected Recovery Time: Immediate return to typical activities with the prosthesis, though optimal functionality may take a few days of adjustment.
• Restrictions: Patient may be advised on specific activities to avoid initially.

Alternatives

• Other Options: Non-locking prosthetic joints, different types of prosthetic enhancements such as electronic or myoelectric options.
• Pros/Cons: Lock mechanisms offer more stability but may lack the natural movement provided by advanced electronic options.

Patient Experience

• During Procedure: Minimal discomfort, primarily related to fitting and minor adjustments.
• After Procedure: Initial period of adaptation, during which the patient may experience slight discomfort or require minor tweaks to the mechanism. Pain management is generally not required, but over-the-counter pain relief can be used if necessary.
