is a condition which causes one or more of the smaller toes to become bent upwards. The toe
can be straightened but if ignored may become a permanent deformity. Each of the 4 smaller toes consist of 3 bones
called phalanges, forming two interphalangeal joints. The toe
bends at the proximal or first interphalangeal joint. Initially it can be straightened, but if left untreated, this can become a permanent deformity.
Poorly fitting shoes and muscle imbalances are the most common causes of hammertoe. When shoes are too narrow or do not accommodate the shape and size of your feet, they often contort the position of your Hammer toes
toes. Choosing a shoe that fits is very important when it comes to avoiding foot problems like bunions or hammertoe. Having your toes bent for an extended period of time in a shoe that is too narrow or small forces your toes to adapt to the cramped space. With time, the muscles in your feet become accustomed to holding the flexed position of your toes, making it harder, or even impossible to straighten them.
The symptoms of a hammer toe
are usually first noticed when a corn develops on the top of the toe
and becomes painful, usually when wearing tight shoes. There may be a bursa under the corn or instead of a corn, depending on the pressure. Most of the symptoms are due to pressure from footwear on the toe
. There may be a callus under the metatarsal head at the base of the toe
. Initially a hammer toe
is usually flexible, but when longstanding it becomes more rigid.
The exam may reveal a toe
in which the near bone of the toe
(proximal phalanx) is angled upward and the middle bone of the toe
points in the opposite direction (plantar flexed). Toes may appear crooked or rotated. The involved joint may be painful when moved, or stiff. There may be areas of thickened skin (corns or calluses) on top of or between the toes, a callus may also be observed at the tip of the affected toe
beneath the toenail. An attempt to passively correct the deformity will help elucidate the best treatment option as the examiner determines whether the toe
is still flexible or not. It is advisable to assess palpable pulses, since their presence is associated with a good prognosis for healing after surgery. X-rays will demonstrate the contractures of the involved joints, as well as possible arthritic changes and bone enlargements (exostoses, spurs). X-rays of the involved foot are usually performed in a weight-bearing position.
Non Surgical Treatment
Hammer toes may be effectively corrected in different ways. Treatments can be non-invasive and involve physical therapy along with the advice that the person not wear any more shoes that restrict appropriate space for their toes. Appropriate shoes for people who want to avoid hammer toes, or for people who already have them, should be at least half an inch longer than the person's longest toe
. High-heeled shoes are something
to definitely avoid.
Joint resection procedures involves removing part of one of the two small joints of the toe
directly underneath where the digit is crooked. The purpose is to make room for the toe
to be re-positioned flat
or straight. Because hammer toes become rigid or fixed with time, removing the joint becomes the only option when the knuckle is stiff. Its important to understand that this procedure does not involve the joint of the ball of the foot, rather the a small joint of the toe
. Medical terminology for this procedure is called a proximal interphalangeal joint arthroplasty or a distal interphalangeal joint arthroplasty, with the latter involving the joint closer to the tip of the toe
