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:
- Assessment and Planning: The prosthetist evaluates the patient's needs and existing prosthetic limb.
- Custom Fitting: The nudge control elbow lock is custom-fitted to ensure it aligns correctly with the patient's prosthetic limb.
- Installation: The device is securely attached and calibrated to the prosthetic limb.
- 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
