Name of the Procedure:

Ankle, Syme's, Molded Socket, SACH Foot (L5050)

Common name(s): Syme's amputation prosthesis, Ankle prosthesis Technical/medical term: Syme's amputation prosthesis with a molded socket and a Solid Ankle Cushion Heel (SACH) foot

Summary

This procedure involves fitting a custom-made prosthesis for individuals who have undergone a Syme's amputation, which involves removing the foot while preserving the ankle joint. The prosthesis includes a molded socket that fits over the residual limb and a SACH foot designed to provide stability and mobility.

Purpose

The procedure aims to restore mobility and improve the quality of life for individuals with a Syme's amputation. The prosthesis helps patients regain the ability to stand, walk, and perform daily activities more comfortably and efficiently.

Indications

• Individuals who have undergone a Syme's amputation.
• Patients experiencing pain or difficulty using an existing prosthetic device.
• Conditions like trauma, severe infection, or tumors leading to a Syme's amputation.

Preparation

• Pre-procedure assessment by a prosthetist to measure and evaluate the residual limb.
• Detailed medical history and physical examination.

• Adjustments in medications or lifestyle as per medical advice.

  Procedure Description

  1. Casting: A plaster or digital scan of the residual limb is taken to create a custom mold.
  2. Socket Fabrication: The mold is used to fabricate a socket that fits the residual limb snugly.
  3. Fitting: The molded socket is attached to a SACH foot, and the entire prosthesis is fitted on the patient.
  4. Alignment and Adjustments: The prosthetist performs several adjustments to ensure proper alignment and comfort.
  5. Training: The patient undergoes mobility training to adapt to the new prosthesis.

Tools and Equipment

• Plaster casting materials or digital scanning technology
• Socket fabrication materials (e.g., thermoplastics)
• SACH foot component

Anesthesia or Sedation

None required for the fitting process.

Duration

The entire process, from casting to final fitting, can take several weeks, with multiple appointments for adjustments.

Setting

The procedure is typically performed in a prosthetic clinic or a specialized rehabilitation center.

Personnel

• Prosthetist: The specialist who designs, fits, and adjusts the prosthesis.
• Physical therapist: Assists with mobility training.
• Physician: Oversees the overall treatment plan.

Risks and Complications

• Skin irritation or pressure sores on the residual limb.
• Improper fit leading to discomfort.
• Potential for wear and tear of the prosthesis components.
• Requirement for regular adjustments and maintenance.

Benefits

• Enhanced mobility and independence.
• Improved ability to perform daily activities.
• Better overall physical comfort and reduced pain in the affected limb.
• Benefits are often realized within a few weeks of adapting to the prosthesis.

Recovery

• Immediate post-fitting care includes monitoring for any skin issues or discomfort.
• Initial restrictions on weight-bearing activities to allow adaptation.
• Regular follow-up appointments for adjustments and maintenance.
• Most patients adapt to the new prosthesis within a few weeks to a few months.

Alternatives

• Below-knee prosthesis: Involves further amputation and may offer different mobility solutions.
• Wheelchair or mobility scooter: Non-surgical options providing mobility without weight-bearing.
• Pros and cons: A below-knee prosthesis may offer more advanced mobility but requires more extensive surgery; non-surgical options may limit active lifestyles.

Patient Experience

• The patient might experience initial discomfort as they adapt to the new prosthesis.
• Mild pain or skin irritation can occur but is typically manageable with proper fit and adjustments.
• Continuous support from healthcare professionals to ensure comfort and successful adaptation.
