Name of the Procedure:

Low Intensity Ultrasound Stimulation (LIUS) to Aid Bone Healing, Noninvasive (Nonoperative)

Summary

Low intensity ultrasound stimulation (LIUS) is a noninvasive procedure that uses sound waves to enhance the healing of bones. The ultrasound device is placed on the skin surface over the injured bone and emits low intensity sound waves to stimulate bone growth.

Purpose

This procedure is aimed at accelerating the healing process of fractures or bone defects. It is particularly useful for non-union fractures where the bone has failed to heal naturally. The goal is to reduce healing time and improve the strength and functionality of the bone.

Indications

• Non-union fractures
• Stress fractures
• Delayed bone healing
• Osteotomy (surgical bone cutting) recovery
• Patients with osteoporosis or other conditions inhibiting bone growth

Preparation

• No fasting or special medication adjustments are usually required.
• The patient might undergo X-rays or other imaging tests to determine the exact location and extent of the fracture.

Procedure Description

1. The patient is positioned in a comfortable manner with the affected area exposed.
2. An ultrasound gel is applied to the skin over the fracture site.
3. The ultrasound device is placed on the gelled area.
4. The device emits low intensity sound waves directed to the bone.
5. The process is monitored and adjusted for optimal efficacy.
6. The procedure is noninvasive and typically pain-free.

Tools and Equipment:

• Ultrasound device
• Conductive gel

Anesthesia:

• Not required

Duration

Each session typically lasts about 20 minutes. The number of sessions and their frequency depend on the individual case, often prescribed as daily sessions over several weeks or months.

Setting

The procedure is usually performed in an outpatient clinic, physical therapy center, or at home with portable units prescribed by a physician.

Personnel

• Physical therapists or trained healthcare providers
• Possibly the patient themselves if using a home unit following initial professional guidance

Risks and Complications

• Minimal to no risks involved
• Rarely, skin irritation from the conductive gel
• No serious complications are typically associated with this procedure

Benefits

• Accelerated bone healing
• Reduction in healing time
• Noninvasive and pain-free
• Can be done at home if prescribed

Recovery

• No downtime; patients can resume normal activities immediately after each session.
• Patients should follow the treatment schedule as prescribed.
• Follow-up appointments to assess healing progress.

Alternatives

• Cast immobilization
• Surgical intervention with bone grafting or internal fixation
• Electrical bone stimulation

Pros and Cons of Alternatives:

• Surgical options are invasive with longer recovery times but may be necessary for severe cases.
• Cast immobilization is less costly but has slower healing compared to LIUS.
• Electrical bone stimulation is another noninvasive option, but its efficacy and convenience can vary.

Patient Experience

During the procedure, patients generally feel no discomfort and can relax or read a book. After the procedure, there should be no pain or downtime. Consistent use as prescribed is key to achieving the best results.
