When is a Bunion Not a Bunion?

It happened again today in my office. A woman came in asking for bunion surgery. She had put up with the pain in her big toe for years and finally had had enough. Many years ago her family physician told her to wait until she couldn’t stand the pain in her foot before discussing surgery with a podiatrist. Like many physicians, she assumed any pain in the great toe accompanied by a bump was a “bunion” or Hallux Abducto Valgus. Unfortunately in this case, she was wrong. The patient actually has Hallux Limitis also known as osteoarthritis of the great toe joint. If she had sought treatment many years ago, her joint may have been salvaged. Now her joint was so destroyed that she needed a joint replacement or fusion. Not what she wanted to hear! In her mind, she came in the office asking for a simple bunionectomy and left needing a joint replacement. She regretted not seeking the advice of a podiatrist earlier.

So what’s the difference between Hallux valgus and Hallux limitis?

Hallux valgus is a crooked big toe joint. Over a period of years, the great toe becomes much friendlier with the second toe and drifts toward and eventually under or over the second toe. At the same time, the first metatarsal (long bone connected to the great toe) drifts towards the center of your body making the distinctive bump. This starts out as a minor annoyance, but then quickly becomes a shoe problem with rubbing on the bump. Most people seek the attention of a podiatrist when the bump is rubbing in their shoe and becomes painful. If the deformity is allowed to progress, the great toe joint can actually start to dislocate and you will start to experience joint pain and degeneration.

Hallux limitis is wear and tear arthritis or osteoarthritis of the great toe joint. Many people are predisposed to have this problem by the underlying biomechanical function of their joint. It becomes much worse after an injury or repetitive trauma from things like high heeled shoes, ballet or some sports. The symptoms are different than Hallux valgus. Hallux limitis usually starts with a feeling of stiffness of the joint. It can be accompanied by swelling and redness. This usually progresses to a decrease in range of motion, a distinctive crunching feeling when moving the joint and then a bump that forms usually more toward the top of the joint, not the side like Hallux valgus.

Hallux valgus and Hallux limitis can occur together in a more complex foot deformity. Usually the bunion deformity has progressed and then is injured by repetitive trauma or a distinctive injury. This starts the progression of the arthritis change. Bottom line: don’t ignore pain in your great toe joint. Treatment of Hallux limitis early can save you from needed a fusion or joint replacement!

Why is treatment of Hallux limitis so important in the early stages?
Once you have destroyed the cartilage in your joint, there is nothing a physician or surgeon can do to make more cartilage. Research is underway trying to replace or regrow cartilage, but we are many years from a solution. Hallux limitis in the early stages can be controlled with a functional shoe orthotic to control the biomechanics. A clean up procedure known as a cheilectomy can help remove all the debris from the joint and get rid of much of the crunching. This will slow down the progression. Some patients can really benefit from a surgical procedure to realign and shorten the metatarsal to give the joint better biomechanics and more joint space. Unaddressed Hallux limitis leads to complete joint destruction and the need for a fusion or joint replacement.

The flip side to this story is that patients with Hallux valgus or your tradition bunion can often delay treatment until they start to have pain. Bunions in the early stages are a cosmetic concern, but the joint is usually not damaged until the later stages. It is important to address Hallux valgus when it starts to hurt so the joint is not permanently injured, but a bump, in the absence, of pain can wait.

The take home message is to have your great toe pain examined by a podiatrist. A full examination including functional biomechanics and x-rays can determine whether your pain is from Hallux valgus, Hallux limitis or a combination. Only then can you make an informed decision on treatments for your foot deformity and pain. Waiting until you can’t stand it anymore is a recipe for unhappy outcomes! If you have great toe pain with or without a bump, don’t delay. See your podiatrist today!

Albert Pujols Twists His Ankle

“Ouch!” Did you see the replay of Albert Pujols twisting his ankle sliding into base? It actually looked much worse than it was in the instant replay. Looked terrible, but he toughed it out and stayed in the game. Boy, did it look like he was going to be in pain this morning! Over and over they played the tape on Sports Center!

What should you do if this happens to you or your child athlete? The trainer from the Cardinals was immediately evaluating Pujols, but most of us don’t have a trainer on standby!

If you have an ankle sprain, you should be evaluated by a sports medicine podiatric foot and ankle surgeon if you have localized pain, swelling and bruising, as well as inability to walk more than 5-7 steps comfortably. Many a foot fracture has been missed in the emergency room when x-rays were taken only of the ankle and not the foot. The fifth metatarsal is often broken with the same mechanism of injury of an ankle sprain, so the foot should be evaluated as well. If severe ligament injury is suspected, an MRI can evaluate the grade of injury. This is really what decides whether surgery is needed for full recovery.

Treatment for ankle sprains really depends on the degree of severity, which can only be determined by your doctor. Initial treatment always includes “R-I-C-E” therapy – Rest, Ice, Compression, and Elevation. Pain and edema is usually controlled with NSAID’s (non-steroidal anti-inflammatories) like ibuprofen. Bracing or casting coupled with non-weightbearing on crutches may be needed in more severe injuries to rest and stabilize the ankle while it heals. Return to pain-free ROM(What is ROM?) and stability is the goal. Surgery is only recommended in Grade 3 severe injuries in athletes or in those patients who have had multiple ankle sprains and suffer from chronic ankle instability. Long-term ankle instability can often be avoided with an aggressive physical therapy program. Bracing should only be used in the short-term during rehabilitation because long-term bracing actually causes atrophy and decreased ROM.

Physical therapy is needed for all ankle sprains. The goals of physical therapy should be to regain full ROM, strength and proprioception (where your brain thinks your ankle is in space). Regaining strength in the peroneal tendons as well as overall balance training are the keys to successful rehabilitation of an ankle sprain. A maintenance program of ankle strengthening, stretching, and proprioception exercises helps to decrease the risk of future ankle sprains, particularly in individuals with a history of multiple ankle sprains or of chronic instability.

Bottom line: if you happen to fall down and go “Boom”, have your ankle sprain evaluated by a podiatric foot and ankle surgeon. Delaying treatment and rehabilitation can lead to life-long instability.

Could it be Ringworm?

Rest easy, Ringworm is an infection of the skin caused by Fungus, not by actual worms. The types of fungi that cause ringworm are found on the superficial (top) layers of the skin. They grow best in warm, moist areas, such as locker rooms, swimming pools and in skin folds.

Ringworm is contagious, and spreads easily through skin to skin contact. It can also spread when you share towels, clothing, or sports equipment.

How do I know if it is Ringworm?

Symptoms of Ringworm usually include a very red itchy rash, it often makes the patttern of a ring. Your skin may be dry, scaly, and thickened in the areas of the rash. Ringworm of the feet may present between the toes and at the soles of the feet.

How is Ringworm treated?
Most times ringworm can be treated with a topical medicine (anti-fungal cream) that you can buy over the counter without a perscription. Make sure you use the cream till the rash is completly gone or you risk the rash coming back. It will take up to 2 weeks for the rash to clear up. If you do not treat the ringworm your skin could blister, have open sores and become infected with bacteria. If this happens you will need antibiotics.

Prevention of Ringworm:
Avoid walking barefoot in locker rooms and near swimming pools
Wash your hands often
Dont share pool towels with your friends
Wash clothes in hot water with fungicidal soap if suspected exposure occurs

If for some reason your rash does not go away with the use of the cream, medical attention is necessary.
