How Melmak works

The Melmak device  utilizes LIPUS techonolgy. LIPUS is an acronym for ‘Low-Intensity Pulsed Ultrasound.’

Low-Intensity Pulsed Ultrasound (LIPUS) is a non-invasive ultrasound techonolgy that is administered directly against the skin, sending a painless mechanical force through the tissue to stimulate the bone to heal.

This process activates cell- reproduction and protein expression and enhances cellular behaviour at the fracture site.


Proven Results backed by Science

The Melmak device has over 20 years of proven results with no known side effects. Melmak is designed to accelerate bone formulation and entered in the TGA (ARTG 297398) as a Class IIA Medical device.

What do the studies show?

Studies using commercially available LIPUS devices have shown that, on average, fresh fractures will heal 38% faster than fractures that have not been treated with ultrasound.

This is dependent on the type and location of the fracture. LIPUS has proven to heal non-union fractures by 86%.

Pre Clinical Studies

LIPUS Clinical Evidence


Of the estimated 156,000 fractures resulting from poor bone health within a year in Australia ,approximately 5-10% demonstrate delayed healing or non-union, a figure that is set to increase as the survival rate for people with serious injuries improves. These delayed or non-healing fractures put a strain on both people, their families and the health care system, often leading to long-term complications that have a high monetary, psychological and physiological cost.

Yes, the Melmak bone growth stimulator is a non-invasive treatment that does not hurt or cause any harm to the body. Most patients do not feel any sensation on the skin, while a few might experience a slight tingly feeling.

The device is not advised for individuals who have pacemakers. If you have a pacemaker, please consult with your doctor or cardiologist first. This device should only be used as prescribed by your health professional.

Please see the question above. Your answer will depend on the location of the fracture. Please consult with your doctor or cardiologist.

Most private insurance companies cover the cost of a bone growth stimulator. As part of our service offering, we handle insurance claims from checking on your coverage, submitting estimates, and direct billing when applicable. We also handle claims with third-party insurance companies.

Clinical studies have proven that one single 20-minute treatment per day is effective in healing the fracture site. Multiple treatments have shown no additional benefits.

You can still use the bone growth stimulator if you have a cast over the fracture site. A window can be cut out of the cast enabling the device to be placed on the fracture site.

You should start treatment immediately to improve healing time, but there is no specific period of when you should or shouldn’t start treatment. If the fracture is a non-union, the bone growth stimulator can still increase the healing time.

No, the device must be in contact with the skin that surrounds the fracture site.

Approximately 10% of all fractures will develop into a delayed or non-union fracture. When a broken bone fails to heal its call a “non-union.” Typically a fracture will be considered non-union or delayed at the 6-8 week mark from the initial fracture date or if the physician is not satisfied with the amount of healing that’s occurred over a period of time.

Due to the extremely low frequency, most patients feel nothing at all.

There are no known contraindications for the Melmak bone growth stimulator. Worthy of note is that both safety and effectiveness have not been studied in individuals whose bones are still growing, pregnant and/or nursing women, people with pacemakers, patients with cancer or patients with poor blood circulation or clotting issues. There have been several cases (very few) where individuals are sensitive to the gel. Alternatives can be found for these individuals. It is recommended that you consult your doctor at all times.

Every Melmak device is tested and inspected to meet standards. You can rest assured that if the device is adequately charged and begins to countdown from 20:00 min to 0:00 that it is working correctly. If you have any questions or concerns, one of our CSR would be happy to assist you.

The Melmak device is indicated for the treatment of fresh bone-fractures and established non-unions. Treatment list includes:

  • Delayed and non-unions
  • Fresh fractures
  • Stress fractures
  • Repair post bone transport procedures
  • Repair post osteotomy
  • Joint fusions
  • Revision surgeries
  • Bunion surgery
  • Accelerating repair in distraction osteogenesis procedures

This list excludes the treatment of the skull and the vertebral column.

Many different risk factors can affect bone healing. Some of the most common are:

  • Age
  • Smoking
  • Diabetes
  • Concomitant medications
  • Vascular insufficiency
  • NSAID use
  • Osteoporosis
  • Fracture location (jones, clavicle, scaphoid, comminuted and butterfly factures)
  • Severity of trauma

Melmak is safe to use with all metal fixation. Test results using significantly higher intensity ultrasound than delivered by Melmack therapy have shown no significant temperature increases and no damage or retardation of healing. The Melmak bone healing system does not affect the stability of the screws.

There are no known contraindications for the use of the Melmak device. Some patients may be sensitive to the ultrasound gel, for those who do, alternatives can be obtained.

The Melmak device uses a very low intensity in a pulsed cycle, making it inherently safe as it is non-thermal and non-cavitating. The device has similar intensity to fetal sonography and is much lower intensity than physical therapy ultrasound.
