Hallux Rigidus and Hallux Limitus



Hallux Rigidus and Hallux Limitus: Description
Description | Symptoms | Causes | Custom Treatments | Non-Custom Treatments | Self Help

Hallux Rigidus and Hallux Limitus are terms that refer to different stages of the same foot problem. 

Terms:
Hallux refers to the big toe.
Limitus refers to decreased motion of the joint. There is less than normal motion available. This is the early stage.
Rigidus denotes a joint that is rigid…very little, if any motion is available. This is the later stage.
 
Definition:
Hallux Rigidus/Limitus involves the 1st metatarso-phalangeal joint.  This joint is located at the base of the big toe.  Hallux Rigidus/Limitus causes pain and stiffness in the big toe, and with time it becomes increasingly harder to bend the toe.  This is a progressive condition during which the toe's motion decreases as time goes on.  In the early stages, motion of the big toe is only limited, and at this point, the disorder is called Hallux Limitus.  As the problem advances, the big toe's motion gradually decreases until it becomes rigid or frozen.  At this point, the disorder is referred to as Hallux Rigidus.  As motion becomes progressively limited, pain increases, especially when the big toe is extended, or pushed up. This condition is frequently seen in younger adults and can occur secondary to athletic sports or injury. Often times a relatively minor injury to the area in high school can precipitate an early painful and limited joint. Essentially this condition is a type of osteoarthritis which may be post-traumatic arthritis to this specific joint. There is an early type of Hallux Limitus, which does not shoe any x-ray signs, but
there is limitation of motion dorsally especially when the foot is on weight bearing load. This is referred to as Functional Hallux Limitus
 
Anatomy:
The problem occurs at the 1st metatarsal head and the base of the 1st proximal phalanx. The fibro-elastic tissue that covers the head of the metatarsal and the base of the phalanx is known as the articular cartilage. The cartilage allows for fluid motion at the joint surface and good cartilage allows free and unrestricted motion at the joint.

 
Hallux Rigidus and Hallux Limitus: Symptoms
Description | Symptoms | Causes | Custom Treatments | Non-Custom Treatments | Self Help
Early Symptoms/Diagnostic Signs (Hallux Limitus):
 
·        Pain and stiffness in the big toe when it is pushed upwards, as occurs when we walk, run,
         squat, and stand on our toes.
·        Swelling and inflammation of the joint, especially on the top of the joint.
·        Discomfort in the joint that occurs when the weather is damp and cold.
·        A feeling of ""tightness"" in and around the joint.
 
Later Symptoms/Diagnostic Signs (Hallux Rigidus):
 
·        Pain in the joint that is almost constant.  May even be felt when resting and the shoe has
         been removed.
·        Crepitus, or a ""grinding"" feeling in the joint when the big toe is moved up and down.
·        A bump, or ""hardness"" can be felt on the top of the joint.  Eventually, this bump which is actually a bone spur, becomes large enough to be seen with the naked eye. 
·        Difficulty wearing shoes, especially high heels, due to the bone spur and stiffness of the big toe joint.
·        Walking becomes so painful that we try to walk without bending the big toe.  This can cause:
     o       Limping
     o       Pain in other parts of the foot, as we try to throw our weight off of the big toe on to the adjacent
              foot structures.  In this way we try to limit bending of the big toe as we walk.
     o       Pain in the knee, hip, and lower back due to changes in the way we walk.
     o       Weight gain due to lack of walking and exercise, because of this pains.
 
                                                                                                                                     
Hallux Rigidus and Hallux Limitus: Causes
Description | Symptoms | Causes | Custom Treatments | Non-Custom Treatments | Self Help
 
Hallux Limitus and Rigidus are due to a premature ""wearing down and tearing"" of the cartilage in the 1st metatarsal-phalangeal joint.  As the cartilage begins to wear down, the proximal phalanx of the big toe, and head of the metatarsal begin to rub against each other.  Without the protection of the cartilage between these bones, each time the toe is moved, friction and pain occur.  Each step that is taken causes more deterioration of the joint cartilage. Continued deterioration of the cartilage results in:

Under the weakened cartilage, the bone tries to regenerate and replace worn down areas. This leads to an over-growth of bone called bone spurs.  These spurs can be felt, and sometimes seen, all around the big toe joint, especially on the top of the joint. Sometimes referred to as a dorsal button.

A narrowing of the 1st metatarso-phalangeal joint, which is evident when radiographs of the foot are taken.

Increased stiffness, swelling, inflammation, and pain in the big toe.  Eventually, when the cartilage has been worn down completely, there is no movement at this joint….the big toe is said to be ""rigid.""

 
Osteoarthritis, or degenerative joint disease, is a term that is used to describe the progressive deterioration of the cartilage in a joint.  Therefore, Hallux Limitus and Hallux Rigidus can be thought of as osteoarthritis of the 1st metatarso-phalangeal joint.  
 
What causes the cartilage to deteriorate?  
 
·        Repetitive Injuries to the joint occur when the big toe is repeatedly jammed backwards, with force, against the joint cartilage.  This retrograde pressure on the cartilage causes the cartilage to prematurely wear down and tear.  Some of the most common causes of this type of injury include:
     o       Frequent wearing of high heel shoes.
     o       Wearing shoes that are too short.
     o       Squatting for long periods of time.
     o       Stubbing the big toe.
     o       Improper running technique. Running on your toes, so that your heel does not touch the ground.
     o       Dropping a heavy object on your big toe joint.
 
·        Age-related changes of the big toe joint, or osteoarthritis.  Osteoarthritis, or degenerative joint disease, is the most common form of arthritis that affects human beings. It is due to the normal wear and tear that our joints undergo during our lifetime. This disease produces a gradual deterioration of the joint cartilage throughout our entire body, including the big toe joint. The saying is true: "If you live long enough, you will develop osteoarthritis."
 
As we age, and osteoarthritis sets in, we begin to notice stiffness, swelling, and a little pain in all of our joints.  One of the most common sites that this occurs in is the big toe joint.  As  osteoarthritis progresses, and the cartilage in the big toe joint deteriorates more, we begin to notice more and more of the symptoms of Hallux Limitus at first, and Hallux Rigidus later on. As mentioned earlier, this problem often manifests in younger patients due to athletic injury or even something as simple as dropping something on the affected area.
 
·        Hereditary Defects are those defects that we are born with, which predisposes us to Hallux Limitus/Rigidus:
     o       Pronation occurs when the foot rolls outward at the ankle, causing one to walk more on the inner border of the foot than is normal.  As we walk, pronation causes us to place excessive weight and pressure on the big toe and big toe joint. When the big toe joint needs to work harder to help ""push"" us forward every time we take a step, due to the extra weight placed on it, the joint cartilage becomes overly compressed.  Eventually, this causes the cartilage to prematurely wear down, resulting in the symptoms of Hallux Limitus.
     o       Feet with high arches are usually more rigid than normal, and will not allow the high arch to come into contact with the ground when we step down. Therefore, as we step forward, all of our weight is thrown on to the balls of the feet, rather than some of the weight being carried by the arch. This will force the bones and joints in the balls of the feet to bear excessive weight, especially the big toe joint. The results of this repetitive and excessive weight on the big toe and big toe joint result in compression, deterioration, and eventually tearing of the joint cartilage. As this continues, the signs and symptoms of Hallux Limitus appear.
     o       An elevated first metatarsal causes the big toe to excessively flex (push downward) with every step we take. When the big toe is in a flexed position and strikes the ground, it is jammed back into the big toe joint cartilage with excessive force, or retrograde pressure. Over time, this results in a thinning and wearing down of the joint cartilage. As this continues, the individual begins to experience the symptoms of Hallux Limitus.
     o       An abnormally long first metatarsal increases stress on the big toe joint each time the big toe ""pushes"" us forward. This stress is further increased if the shoe is too short or the heel is too high, as this forces the big toe back into the joint cartilage with excessive force. The joint cartilage becomes pinched between the big toe and the metatarsal, causing premature wearing and deterioration of the cartilage. This results in the uncomfortable symptoms of Hallux Limitus.  (In most instances you can determine if your first metatarsal is too long by the fact that the big toe appears too long, in relation to your other toes). This also applies if the 2nd metatarsal is very short creating an abnormal parabola thereby increasing stress on the 1st metatarsal joint.

Self-Treatment or Prevention: The old adage, ""An ounce of prevention is worth a pound of cure,"" is most apropos when trying to prevent the devastating effects of Hallux Limitus and Rigidus.  If this disease is not prevented or treated in its earliest stages, it may produce such debilitating pain and deformities that surgery will be required to allow the foot to function normally again.

Long Term Treatment
must be directed towards:
               ·      Stabilizing the foot. When the foot is maintained in its normal, or neutral position, it
                      cannot pronate and roll out. When pronation is controlled, the big toe no longer bears
                      excessive weight. This reduces forceful and destructive compression of the cartilage in
                      the big toe joint. Thus, the big toe joint remains healthy.
               ·      Supporting high arches in order to relieve excess pressure on the balls of the feet,
                      especially the big toe joint. When the big toe no longer must bear excessive amounts of
                      weight as it ""pushes"" us forward, the big toe joint cartilage is protected from
                      excessive compression and force. The result is a healthy joint cartilage, free of deterioration
                      and tearing.
              ·       Stabilizing the big toe, and preventing it from ""over-flexing,"" as it pushes us forward.
                      This will help to reduce the excessive jamming back of the big toe into the joint
                      cartilage. Without this jamming effect, the cartilage remains healthy and intact. 
              ·       Providing shock absorption for the foot. The arches of our feet are our body's main
                      shock absorbers. As we take each step, the arch of the foot helps to absorb and disperse
                      the tremendous force that occurs when our foot strikes the ground. This force can equal 3 to
                      7 times our body weight, depending on whether we are walking or running. When the arch
                      is higher than normal, shock absorption by the arch is reduced. When this occurs, the big
                      toe, ball, and heel of the foot, must absorb this shock.  The effect on the big toe is to
                      over-flex, or to be jammed back into the joint cartilage with excessive force, which may
                      cause the cartilage to wear down prematurely and unevenly.
 
Custom-Made Orthotics are considered to be the "Gold-Standard" of medical treatment, especially in the prevention and early stages of Hallux Limitus/Rigidus. Our custom-made orthotics for this condition are constructed of thin, comfortable, shock absorbent "space age" materials, which gently and effectively:
 
     ·    Stabilize the foot by using uniquely placed medial wedges, deep heel cups, and "posts"
          (stabilizers). When the foot is stabilized, it is brought back to a neutral or normal alignment.
          When the foot is in its normal alignment, pronation is reduced or completely corrected, and, the
          big toe is no longer forced to bear excessive body weight. This prevents abnormal wear and tear
          on the big toe cartilage, and helps to stop or prevent Hallux Limitus/Rigidus from occurring. 
     ·    Provide the specific amount of arch support that your foot requires. Our custom-made orthotics
          support not only the arch as a whole, but each individual bone and joint that forms the arch.
          When the arch is properly supported, it is allowed to function  in providing optimal shock
          absorption for the foot, especially to the big toe joint.  This will reduce the wear and tear on
          the joint cartilage.
     ·    Stabilize the big toe and limit its movement during the gait cycle. This is accomplished through
          the use of a uniquely placed ""stabilizer"" called a Morton's Extension. It is embedded in our
          custom-made orthotics, and placed under the 1st metatarso-phalangeal joint and big toe. It is a
          semi-rigid platform, which is covered by a padded material to ensure comfort. This Extension limits
          the motion of the big toe joint, thus reducing or eliminating pain.  It works in two ways:
              o  It reduces/or prevents the big toe from bending and pushing us forward as we walk or run.
              o  Its shape allows for a slight tilting of the forefoot that ""off-loads"" the weight from
                 the big toe to the remaining structures of the forefoot and  toes. When this occurs, the
                 big toe is allowed to ""rest,"" while the orthotic itself, and the other foot structures take
                 over the job of the big toe.
          Reducing movement of the big toe, as well as the amount of weight it must bear results in
          a reduction or complete elimination of:
              · Pain.
              · Joint cartilage destruction.
              · Bone spur formation around the big toe joint.
          Walking can become fun again.

 
The lighter tan material is the Morton's Extension. It extends under the big toe and 1st meatatarso-phalangeal joint.

Hallux Rigidus and Hallux Limitus: Non-Custom Treatments
Description | Symptoms | Causes | Custom Treatments | Non-Custom Treatments | Self Help

All conservative treatments begin with the shoes that you wear.  While shoes may help to reduce the pain of Hallux Limitus and Rigidus, they do not seem to prevent this disease from becoming worse.  This is due to the fact that shoes wear down quickly, and whatever soothing effects they may have when they are new, are quickly lost as they wear down.  This is one reason why custom-made orthotics are more cost effective than orthopedic shoes…custom-made orthotics last for years without breaking down, while shoes do not.
 
Make sure that your shoes are:
  • Wide enough across the ball of the foot and toe area, so that there is no pressure on the big toe and its joint.
  • The shoes must be long enough in order to prevent pressure on the tip of the toe.
  • The heel of the shoe should be no higher than 1"".
  • The sole of the shoe should be rigid, in order to reduce bending of the big toe when walking.
 
Hallux Rigidus and Hallux Limitus: Self Help Treatments
Description | Symptoms | Causes | Custom Treatments | Non-Custom Treatments | Self Help
Immediate Treatment must be directed towards reducing the inflammation, swelling, and pain in the big toe and its joint, the 1st metatarso-phalangeal joint. In the very early stages of Hallux Limitus, the following self-help treatments may be effective:
  • Rest the foot by keeping weight off of it. Each time you take a step, the big toe joint is aggravated and abused. It cannot calm down if you do not keep weight off of the foot.
  • Shoes can help to protect the big toe joint if they have the following features:
    • A rigid sole. This will help to reduce bending of the big toe with each step that is taken.
    • A wide and deep toebox keeps pressure off of the big toe and swollen joint.
    • A flat shoe reduces compression and injury of the big toe joint cartilage. High heels and short shoes jam the big toe back in the joint with excessive force, causing destruction of the joint cartilage.
    • Proper length shoes will also go a long way in reducing jamming of the big toe into the joint cartilage. 
  • Reduce pressure on the big toe joint.  Use a soft gel pad to cushion the ball of the foot and reduce pressure on the big toe joint.  Dr. Jill's self-stick pads make for easy application, and are re-usable. Click here for more information.
  • Soaking the foot in warm water may help to soothe the inflamed and painful big toe joint. The soaking water must be comfortably warm and not hot, as hot water will usually cause discomfort, skin burns, and increased joint inflammation and swelling. Soaking for 10 to 15 minutes two or three times a day is usually suggested. If soaking increases pain, swelling, or inflammation, stop immediately.
  • Gentle massage with a topical pain reliever can help to provide comfort. By combining the pain relieving properties of Tripod Labs Flexstat Topical Pain Reliever with gentle massage, pain, swelling, and inflammation can be reduced or eliminated.
If the pain becomes worse, the foot more swollen or inflamed, or if you think that you have a serious problem, see a doctor immediately.
