Name of the Procedure:

• Common Name: Adjustable Ankle Foot Orthosis
• Technical Term: Static or Dynamic Ankle Foot Orthosis, Including Soft Interface Material, Adjustable for Fit, for Positioning, May Be Used for Minimal Ambulation, Prefabricated, Off-the-Shelf
• HCPCS Code: L4397

Summary

An adjustable ankle foot orthosis (AFO) is a prefabricated device designed to support and stabilize the ankle and foot. It includes a soft interface material for comfort and can be adjusted to fit the patient's limb. This orthosis helps with positioning and allows for minimal walking or ambulation.

Purpose

• Medical Conditions: Used for conditions such as foot drop, ankle instability, or weakness due to neurological or musculoskeletal disorders.
• Goals: To provide stability and support to the ankle and foot, improve mobility, prevent deformities, and enhance overall function during rehabilitation.

Indications

• Symptoms/Conditions: Foot drop, lower limb paralysis, ankle instability, post-stroke rehabilitation, multiple sclerosis, cerebral palsy, and injuries or surgeries affecting the ankle and foot.
• Criteria: Patients with difficulty in ambulating due to ankle and foot issues who need an external device for support and positioning.

Preparation

• Instructions: No specific pre-procedure instructions like fasting are usually required.
• Assessments: Clinical assessment by a healthcare professional to determine fit and suitability. Measurements of the limb may be necessary.

Procedure Description

1. Fit Assessment: The healthcare professional assesses the fit by measuring the patient's ankle and foot.
2. Adjustment: The adjustable straps and components of the AFO are customized to ensure proper support and comfort.
3. Fitting: The orthosis is fitted onto the patient's leg and adjusted to ensure adequacy for support and positioning.
4. Instruction: Patients are instructed on how to wear, remove and care for the orthosis.

• Tools: Adjustable prefabricated AFO device, measurement tape, padding materials.
• Anesthesia: Generally not required for this procedure.

Duration

• Typically, the fitting and adjustment process takes about 30 to 45 minutes.

Setting

• The procedure is often completed in an outpatient clinic, rehabilitation center, or an orthotic/prosthetic facility.

Personnel

• Healthcare providers involved include orthotists, physical therapists, and sometimes physicians.

Risks and Complications

• Common Risks: Discomfort, pressure sores, skin irritation.
• Rare Risks: Severe skin breakdown, improper fitting leading to further mobility issues.
• Management: Regular follow-up appointments to adjust the fit and address issues, proper patient education on usage and skin care.

Benefits

• Expected Benefits: Improved mobility and stability, prevention of deformities, enhanced quality of life.
• Realization Time: Benefits can often be noticed immediately once the patient begins using the device, with continued improvement over time.

Recovery

• Post-Procedure Care: Regular cleaning and maintenance of the orthosis, monitoring skin for any signs of irritation.
• Recovery Time: Varies; patients typically continue their activities of daily living while adapting to using the AFO.
• Follow-Up: Regular follow-up visits to adjust the orthosis as necessary.

Alternatives

• Other Options: Custom-made AFOs, physical therapy, surgical interventions.
• Pros and Cons: Custom-made AFOs offer a tailored fit but are more expensive and take longer to produce. Physical therapy may help but might not provide sufficient support. Surgical options are invasive with longer recovery times.

Patient Experience

• During Procedure: Patients might feel pressure during fitting but should not experience pain.
• After Procedure: Adjustment period to get used to the orthosis, some initial discomfort or awkwardness in walking may be experienced.
• Pain Management: Any discomfort can generally be managed with proper adjustments and wearing schedules. Healthcare providers will offer specific advice to enhance comfort.
