WHAT ARE OVERLAPPING TOES



Overlapping toes is a condition that may be present at birth (congenital) or in most cases develops later on in life. The condition may affect the patient by being nothing more than unsightly and a slight inconvenience when selecting shoes, all the way up to very painful in most shoes.

Diabetics, those with poor circulation, and individuals with nerve impairment are at greater risk with this type of foot structure because of the friction and pressure points that are created with toes that do not line up straight.

In many instances overlapping and underlapping toes may be a result of a hammertoe deformity or a bunion deformity. overlapping_toes

In severe bunion deformities, as the big toe moves toward the second toe, the big toe may either go under the second toe, usually forcing the second toe to become a hammertoe. Other times the big toe may deviate over the second toe, forcing the second toe into the ground as the patient walks, usually creating pain in the second toe. In either situation the second toe may become painful even though there is no pain in the bunion joint. From a strictly surgical standpoint, many times it is necessary to correct the non-painful bunion deformity along with the second toe in order to bring about relief. There are however, instances where only the second toe requires surgical correction and the bunion may be left alone. In these cases the bunion deformity is mild and only putting marginal pressure on the second toe.

As toes become more arthritic they start to change shape and in turn no longer line up properly. Compounding this is the formation of bone spurs that may be present on each toe. If two of these bone spurs happen to press against each other they create excessive pressure points which can lead to corns or even bursitis. In the case of a poorly controlled diabetic, or an individual with inadequate circulation or diminished neurological sensation, the excess pressure point can cause the tissue to break down, become infected, or ulcerated creating a serious medical problem.overlapping_second_toe

Conditions such as rheumatoid arthritis can exacerbate this problem and grossly deform the appearance of the toes.

Some people have an inherited tendency to develop overlapping toes. The most commonly observed incidence is an overlapping fifth toe which bends over the fourth toe. This may occur on one or both feet. In most cases it is more annoying than anything else, however, there are cases where it can become a problem as a person ages. In women, the ability to wear a high style dress shoe may be hampered by the overlapping fifth toe. Because of the tightness of the space between the fourth and fifth toes, some people will develop chronic athletes foot, due to the dark constantly moist environment that is created between the two toes. When a congenital overlapping fifth toe becomes a problem that is not alleviated by shoe selection or padding, it may be surgically corrected. congenital_fifth_toe

As originally stated most cases of overlapping toes are more a cosmetic issue than painful problem.

TREATMENT OF OVERLAPPING TOES



conservative approach to overlapping toes

Non-surgical treatment includes proper shoe selection where the shoe has a wide and high toe box to allow for the toe deformity without putting too much pressure on any of the toes. For you women reading this article, remember, tight pantyhose will also contribute to this problem.

There is no shortage of padding sold in drug stores these days. As long as they are non-medicated you might have to experiment around with some of the different types of pads in an effort to find the best one for you. The reason you do not want to use a medicated pad is because these pads generally contain an acid compound which attempts to "eat" away at any corn that you may have. The problem is the acid does not know when to stop and I see people in the office with infections and small ulcers as a result of having used too much acid or having left the dressing on for too long. Again, this is particularly a problem in diabetics, those with poor circulation, and impaired neurological sensation.

surgical approaches to overlapping toes

There are two approaches to correcting the congenital overlapping fifth toe. One is to do a skin-plasty procedure where the tension on the skin just behind the fifth toe is released and redirected in an effort to allow the fifth toe to line up next to the fourth toe instead of overlapping. When the deviation of the fifth toe is too great, and it is deemed that a skin-plasty would not be sufficient to straighten the toe, then another option is to fuse the fifth toe to the fourth toe. This too is a soft tissue procedure where the fifth toe is sewn to the fourth toe. For many this is not an acceptable option because even though the fifth toe is now straight and not overlapping, the fourth and fifth toes are now connected as one.

I should also mention that back in the "old" days many surgeons would just amputate the fifth toe as a means to an end.

As far as surgical treatment goes for overlapping toes other than the congenital overlapping fifth toe, there are various approaches and procedures and each patient needs to be evaluated individually to determine how much surgery and what types of procedures will most benefit them.

Soft tissue procedures Some of the available procedures include soft tissue releases where the tendon on top or bottom of the toe is either cut or just lengthened in an effort to redirect the position of the toe. This may also include what is known as a capsulotomy where the ligament that attaches one bone to the next is partially incised, again in an effort to redirect the toe. In general, these procedures will not adequately re-position a toe and more work, particularly bone work, will need to be done.

Bone surgery includes arthroplasty where the actual joint between two bones is remodeled usually be removing a small piece of bone. (This the most common type of hammertoe surgery performed) A joint fusion many times is performed instead where the joint is fused. The toe is aligned in the position the surgeon desires, then fuses the joint, to keep the toe in a straight alignment. Although cosmetically the toe will look much better, what has been created is what is known as a "pencil toe" meaning the toe will not bend. In most cases this should not be an issue. What does become an issue is if the resulting straight toe (usually the second toe) is too long relative to the length of the other toes. In these cases it is very common for the patient to develop and corn at the end of the toe because the toe constantly butts up against the end of the shoe and because the toe does not bend, there is a lot of pressure created on the end of the toe and a corn forms.

Contrary to what you may read elsewhere, there are no exercises that will straighten your toes, however, in many cases the formation of overlapping toes, bunions and hammertoes are the result of an abnormality in one's gait. A proper evaluation by a podiatrist can determine if that is part of the problem. If so, with the proper use of an orthotic, the abnormal gait pattern can be corrected and thus remove the factors that are causing the toes to deviate. Obviously, the younger a person is when they are evaluated and the earlier treatment is instituted, and the better a person complies, the better the anticipated outcome.
