Name of the Procedure:

Prosthetic Sheath, Below Knee (L8400)
Common Name: Below Knee Prosthetic Sheath
Technical or Medical Term: Below Knee Sock Liner for Prosthetics

Summary

A prosthetic sheath is a protective liner worn over the residual limb (stump) of a person who has undergone a below-knee amputation. It helps provide a comfortable interface between the skin and the prosthetic socket, reducing friction and enhancing the overall comfort and fit of the prosthetic limb.

Purpose

The prosthetic sheath addresses discomfort caused by the contact between the skin and the prosthetic socket. The goal is to reduce skin irritation, protect against pressure sores, and improve the fit and function of the prosthetic limb. This ultimately aims to enhance the mobility and quality of life for the amputee.

Indications

• Individuals with below-knee amputations.
• Patients experiencing skin irritation, blistering, or sores from the prosthetic socket.
• Those needing an improved fit and comfort for their below-knee prosthesis.

Preparation

• Ensure the residual limb is clean and dry before application.
• Regular skin inspections should be conducted to ensure there are no open sores or infections.
• No specific fasting or medication adjustments are necessary before using the prosthetic sheath.

Procedure Description

1. Clean the residual limb thoroughly and pat it dry.
2. Roll the prosthetic sheath down over the limb, ensuring it lays flat and smooth against the skin.
3. Position the prosthetic socket over the sheath, adjusting for comfort and proper fit.
4. Secure the prosthesis as per the usual protocol, checking again for any discomfort or irregularities.

Tools and Equipment:

• Prosthetic Sheath (Below-Knee Sock Liner)
• Below-Knee Prosthetic Socket
• Residual Limb Cleaning Supplies

Anesthesia or Sedation:

• None required

Duration

The application of a prosthetic sheath typically takes a few minutes.

Setting

This procedure can be performed at home, in a doctor’s office, or at a prosthetist's clinic.

Personnel

• Prosthetist (initial fitting and guidance)
• Patient or Caregiver (daily application and maintenance)

Risks and Complications

• Skin irritation if not fitted properly.
• Potential for bacterial or fungal infections if the sheath is not kept clean and dry.
• Development of pressure sores if the sheath or socket is not correctly aligned.

Benefits

• Improved comfort and skin protection.
• Enhanced mobility and prosthesis function.
• Immediate reduction in friction-related issues.

Recovery

• No specific recovery time needed.
• Regular inspections and proper hygiene are advised.
• Follow-up appointments with the prosthetist for adjustments based on wear and individual needs.

Alternatives

• Gel liners for prosthetics: Offer enhanced cushioning but can be more expensive.
• Foam prosthetic liners: Also provide cushioning but may be bulkier.

Patient Experience

Patients will typically experience immediate comfort improvement upon using the prosthetic sheath. There may be an initial adjustment period to getting the sheath to fit correctly, but regular use should lead to greater comfort and fewer skin problems. Pain management is generally not a concern for this procedure, but consistent evaluations and adjustments can further enhance user experience.
