Morton's extension, also known as the Morton foot orthosis, is a type of medical device that is commonly used to provide support and stabilization for the ankle and foot. It is characterized by a semi-rigid plastic or carbon fiber shell that is tailored to fit comfortably within the shoe. The extender extends from the sole of the shoe, just anterior to the heel, and limits the mobility of the great toe joint.
History of Morton's Extension
The concept of a Morton's extension, also known as the Morton foot orthosis, was first proposed by Dr. John R. Morton in 1870. Dr. Morton was a pioneering surgeon who is credited with developing numerous surgical techniques and diagnostics, including the first successful appendectomy.
Description of Morton's Extension
A Morton's extension is a semi-rigid plastic or carbon fiber arch support that is commonly used to provide stability and support for the ankle and foot. The extender is typically made from highdensity ethylene vinyl acetate (EVA) or polypropylene. It is contoured to fit neatly within the shoe and extends forward from the sole of the shoe, just anterior to the heel.
The extension is designed to limit the mobility of the great toe joint and support the subtalar joint. This can be particularly useful for individuals who suffer from hallux limitus or hallux rigidus. Hallux limitus is a condition characterized by a limitation in the range of motion of the great toe joint, while hallux rigidus is a more advanced stage of the same condition characterized by a fixed and immovable great toe joint.
Function of Morton's Extension
The primary function of a Morton's extension is to provide support and stabilization for the ankle and foot. It is commonly used to treat conditions such as hallux limitus, hallux rigidus, turf toe, sesamoiditis, sesamoid fractures, and ulcerations of the great toe (diabetic). It can also be used to correct bunions, fallen arches (pes planus), and metatarsalgia (pain along the instep).
Indications for Morton's Extension
Conditions such as hallux limitus, hallux rigidus, turf toe, sesamoiditis, sesamoid fractures, ulcerations of the great toe (diabetic), and bunions may benefit from a Morton's extension. It is important to note that the severity and presentation of these conditions can vary widely among individuals, as can their response to treatment.
Contraindications for Morton's Extension
It is important to note that a Morton's extension is not appropriate for everyone. For example, individuals with severe ankle or foot instability, severe arthritis, or severe neuropathy may not be good candidates for this type of orthosis. Additionally, individuals with certain medical conditions such as diabetes should consult with their physician before using a Morton's extension.
Manufacturers and Brands of Morton's Extension
There are several manufacturers and brands of Morton's extensions available on the market. Some of the most popular brands include Dr. Scholl's, Dr. Comfort, Dr. Attenborough, and McDavid. Each manufacturer may offer slightly different designs and styles of Morton's extensions, so it is important to choose an option that best suits your needs and preferences.
Care and Maintenance of Morton's Extension
It is important to take proper care and maintenance of your Morton's extension to ensure that it continues to provide optimal support and comfort. Here are some tips for caring for your orthosis:
- Clean your orthosis regularly with a mild soap and water, making sure to remove any dirt or debris that may have accumulated.
- Avoid exposure to extreme temperatures or wet conditions, as this can affect the flexibility and comfort of the orthosis.
- Be cautious when using public transportation or walking in areas where the ground may be muddy or wet, as this can create additional wear and tear on your orthosis.
- Always store your orthosis in its original packaging until you are ready to use it again.
FAQs
Q: Can I wear a Morton's extension with a thin sole?
A. Often, yes. If the thickness of the shoe's insole matches the thickness of the carbon fiber extension, it may work well. Try it on with the shoe you plan to wear it with and move your feet around to see how it feels.
Q: How do I know if a Morton's extension is the right size for me?
A. Measuring your foot while weight bearing in centimeters is the best way to determine the appropriate size. If your foot is between sizes, round down to the smaller size. You can also measure in inches and use the ruler below the page to determine the appropriate size in centimeters.
Q: Can I cut my Morton's extension to fit my specific shoes?
A. It may be possible to modify an already existing Morton's extension to better fit your specific shoes. However, this should only be done carefully and with the guidance of a professional Orthotist. Cutting can potentially reduce the integrity and effectiveness of the orthosis.
Q: What kind of materials is a Morton's extension made from?
A. Morton's extensions are typically made from high密度 ethylene vinyl acetate (EVA) or polypropylene. Both materials are durable, comfortable, and suitable for long-term wear.
Q: Are Morton's extensions covered by insurance?
A. Insurance coverage for Morton's extensions varies widely depending on your specific plan and the circumstances of your condition. It may be necessary to consult with your insurance carrier to determine if coverage is available for your treatment.
Morton's extensions are a versatile and effective tool in the treatment of various foot conditions. They can provide additional support and stability to the ankle and foot, helping to alleviate pain and improve mobility.
