Name of the Procedure:

Prehensile actuator, switch controlled (HCPCS Code: L7040)

Summary

The prehensile actuator, switch controlled, is a device fitted to a prosthetic limb that enables individuals with limb differences to perform grasping and holding functions. This device helps to restore a level of hand functionality by mimicking the grasping motion, controlled by a switch mechanism.

Purpose

The prehensile actuator is designed to help individuals who have lost hand functionality due to amputation or congenital limb differences. The primary goal is to enhance the user's ability to perform daily tasks such as holding objects, thereby improving quality of life and functional independence.

Indications

• Amputation of the upper limb
• Congenital limb differences affecting hand function
• Patients requiring improved grasping capability on a prosthetic limb

Patient criteria include:

• Stable residual limb health
• Motivation and willingness to use and maintain the prosthetic device
• Ability to operate switch controls

Preparation

• Fitting appointments to customize the prosthetic limb
• Training sessions to teach the patient how to use the switch control
• No specific dietary or medication adjustments are typically needed

Procedure Description

1. Fitting: The prosthetic limb is fitted with the prehensile actuator device.
2. Training: The patient learns how to operate the switch control. This usually involves a series of sessions with an occupational therapist or prosthetist.
3. Adjustment: Fine-tuning the device to ensure optimal performance and comfort for the patient.

Tools and equipment include:

• The prehensile actuator device
• Prosthetic limb components
• Switch control mechanisms

No anesthesia or sedation is involved as this is a non-invasive procedure.

Duration

The initial fitting and adjustment process may take several hours, typically spread over a few appointments. Training sessions are ongoing until the patient is comfortable using the device.

Setting

This procedure is carried out in an outpatient clinic or a specialized prosthetic fitting center.

Personnel

• Prosthetist
• Occupational Therapist
• Prosthetic Technicians

Risks and Complications

• Skin irritation or pressure sores from the prosthetic
• Device malfunction or breakdown
• Difficulty in learning to use the switch control
• Psychological adaptation to using a prosthetic device

Benefits

• Improved ability to grasp and hold objects
• Enhanced independence in daily activities
• Better quality of life and self-esteem Benefits are often realized immediately after the patient becomes proficient in using the switch control.

Recovery

• Regular follow-up appointments to check the fit and functionality of the prosthetic device
• Continuous practice to improve proficiency
• No specific physical recovery needed as this is a non-surgical procedure

Alternatives

• Body-powered prosthetics with manual control
• Myoelectric prosthetics that use muscle signals to control movements
• Cons of alternatives may include higher costs, greater maintenance needs, or different usability comfort levels compared to the switch-controlled prehensile actuator.

Patient Experience

Patients might initially find it challenging to learn to control the device using the switch but usually adapt with practice. They may feel discomfort during the initial fitting period, which typically resolves with adjustments. Pain management and comfort measures include proper fitting and regular follow-ups to address any issues.
