Name of the Procedure:

Upper Extremity Addition, Nudge Control Elbow Lock (L6637) Common name(s): Elbow lock, nudge control elbow lock Technical/medical term: L6637 – Upper Extremity Addition, Nudge Control Elbow Lock

Summary

The nudge control elbow lock is a specialized device added to a prosthetic arm to allow individuals with upper extremity amputations or impairments to manually lock their elbow in a desired position using a simple nudge mechanism. This addition can significantly improve the functionality and usability of a prosthetic limb.

Purpose

Medical Conditions or Problems it Addresses:

• Upper extremity amputations
• Loss of elbow joint functionality

Goals or Expected Outcomes:

• Enhanced control over the positioning of the prosthetic arm
• Improved range of daily activities
• Increased independence and quality of life

Indications

Specific Symptoms or Conditions:

• Individuals with upper extremity limb loss who require improved elbow positioning capability in their prosthetic arms

Patient Criteria or Factors:

• Need for enhanced control over prosthetic limb movement
• Sufficient residual limb function to operate the nudge mechanism

Preparation

Pre-Procedure Instructions:

• No specific fasting or medication adjustments necessary
• Adjustment of the prosthetic device by a certified prosthetist

Diagnostic Tests or Assessments:

• Evaluation of the residual limb by a prosthetist
• Measurement and fitting assessment to ensure appropriate sizing and functionality

Procedure Description

Step-by-Step Explanation:

1. Assessment and Planning: The prosthetist evaluates the patient's needs and existing prosthetic limb.
2. Custom Fitting: The nudge control elbow lock is custom-fitted to ensure it aligns correctly with the patient's prosthetic limb.
3. Installation: The device is securely attached and calibrated to the prosthetic limb.
4. Training: The patient is trained on how to use the nudge mechanism to lock and unlock the elbow joint.

Tools, Equipment, or Technology Used:

• Nudge control elbow lock component
• Tools for attaching and adjusting the device

Anesthesia or Sedation Details:

• Not applicable, as this is a non-invasive procedure

Duration

Typically takes 1 to 2 hours, including assessment, fitting, installation, and training.

Setting

Performed in an outpatient clinic or a specialized prosthetic center.

Personnel

• Certified prosthetist
• Prosthetic technician (if needed)

Risks and Complications

Common Risks:

• Discomfort or pressure sores from improper fit ##### Rare Risks:
• Mechanical failure of the device
• Skin irritation from contact with the device

Management:

• Regular follow-up appointments for adjustments
• Immediate consultation if discomfort or mechanical issues arise

Benefits

Expected Benefits:

• Greater control over prosthetic limb movement
• Ability to perform a wider range of activities with ease ##### Realization Timeline:
• Benefits are typically realized immediately after installation and training, with continued improvement over time as the patient becomes more proficient.

Recovery

Post-Procedure Care and Instructions:

• Daily checks to ensure the device is functioning properly
• Regular cleaning and maintenance of the prosthetic limb and the lock mechanism ##### Expected Recovery Time:
• No recovery time needed; patients can resume regular use of their prosthetic limb immediately

Restrictions and Follow-Up:

• Initial follow-up visit within a week of installation, followed by regular check-ups every few months

Alternatives

Other Treatment Options:

• Traditional elbow locks without nudge control
• Myoelectric prosthetic arms with powered elbow movement

Pros and Cons:

• Traditional locks are less expensive but offer less control.
• Myoelectric arms provide advanced functionality but can be more costly and require more maintenance.

Patient Experience

During the Procedure:

• Minimal discomfort, similar to routine fitting adjustments ##### After the Procedure:
• Improved functionality in the prosthetic limb
• Initial learning curve for operating the nudge mechanism ##### Pain Management and Comfort Measures:
• Proper fitting to avoid any discomfort
• Support and guidance from the prosthetist to ensure the device is comfortable and easy to use
