Uneven muscle tension results in the distortion of one or several of the small toes. (hammertoe) Pressure points develop at the raised middle joint as well as at the tip of the toe and underneath the metatarsal head. In the beginning, when the misalignment can still be corrected, it often suffices to lengthen the tendon and to cut a notch into the capsule. In a contracted misalignment, part of the middle joint is removed to form a replacement joint. Modern surgical techniques preserve the metatarsophalangeal joint (Weil or Helal osteotomies).
If a foot is flat (pes planus, pronated), the flexor muscles on the bottom of the foot can overpower the others because a flatfoot is longer than a foot with a normal arch. When the foot flattens and lengthens, greater than normal tension is exerted on the flexor muscles in the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe. If a foot has a high arch (pes cavus, supinated), the extensor muscles on the top of the foot can overpower the muscles on the bottom of the foot because the high arch weakens the flexor muscles. This allows the extensor muscles to exert greater than normal tension on the toes. The toes are not strong enough to resist this tension and they may be overpowered, resulting in a contracture of the toe, or a bending down of the toe at the first toe joint (the proximal interphalangeal joint) which results in a hammertoe.
Symptoms include sharp pain in the middle of the toe and difficulty straightening the toe. People with hammertoe may also develop blisters, which are fluid-filled pockets of skin, because the bent toe is likely to rub against the inside of a shoe. This increased friction may also lead to calluses, which are areas of thickened skin, and corns, which are hard lumps that may form on or between toes. Symptoms may be minor at first, but they can worsen over time.
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.
Non Surgical Treatment
Mild hammer toe in children can be treated by manipulating and splinting the affected toe. The following changes in footwear may help relieve symptoms. Wear the right size shoes or shoes with wide toe boxes for comfort, and to avoid Hammer toe making hammer toe worse. Avoid high heels as much as possible. Wear soft insoles to relieve pressure on the toe. Protect the joint that is sticking out with corn pads or felt pads. A foot doctor can make foot devices called hammer toe regulators or straighteners for you, or you can buy them at the store. Exercises may be helpful. You can try gentle stretching exercises if the toe is not already in a fixed position. PIcking up a towel with your toes can help stretch and straighten the small muscles in the foot.
Hammertoe surgery is performed when conservative measures have been exhausted and pain or deformity still persists. The surgery is performed on an outpatient basis. It typically required about one hour of time. An incision is placed over the inter-phalangeal joint. Once the bone is exposed, the end portion of the bone is removed. Your surgeon may then use pins or other fixation devices to assist in straightening the toe. These devices may be removed at a later date if necessary. Recovery for hammertoe surgery is approximately 10 to 14 days. You are able to walk immediately following the surgery in a surgical shoe. Swelling may be present but is managed as needed. Physical therapy is used to help reduce swelling in the toe or toes after surgery. Most of these toe surgeries can be performed in the office or the outpatient surgery under local anesthesia.
