OverviewHammertoes are another forefoot deformity that can take a walker out of their activity. A Hammertoes generally represent a tendon imbalance in the toes caused by one of the toe tendons getting an advantage over another toe tendon. Most commonly, it is one or all of the long extensor tendons on the top of the foot that gets an advantage over one or all of the flexor tendons on the bottom of the foot, to cause the first joint in the toe to be elevated above the ground. Most shoe wearing people chronically alter the delicate balance that co-exists amongst the toe tendons whether they know it or not.
Causes
Hammertoes are most common in women, and a big part of this is poor shoe choices, which are a big factor in the development of many foot problems. Tight toe boxes and high heels are the biggest culprits. Genetics certainly plays a role in some cases of hammertoes, as does trauma, infection, arthritis, and certain neurological and muscle disorders. But most cases of contracted toes are associated with various biomechanical abnormalities in how a patient walks. This causes the muscles and tendons to be used excessively or improperly, which deforms the toes over time.
Symptoms
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.
Diagnosis
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
Conservative treatment is limited to accommodation, not correction, of the deformity, though some patients find the relief they can get from these options to be more than enough to put off or even avoid surgery. These include better Footwear. Shoe gear with a wider toe box and higher volume causes less friction to the toes. Toe Braces and Strapping. Some toe braces and strapping techniques take some pressure off the toes during gait. Custom molded orthotics can redistribute the forces through the tendons that control the toe, lessening the pain and extent of the deformity.The calluses on the toe and the ball of the foot can be shaved occasionally to reduce some pain and pressure, although they will return due to the constant deformity.
Surgical Treatment
If your hammer, claw, or mallet toe gets worse, or if nonsurgical treatment does not help your pain, you may think about surgery. The type of surgery you choose depends on how severe your condition is and whether the toe joint is fixed (has no movement) or flexible (has some movement). A fixed toe joint often requires surgery to be straightened. A flexible toe joint can sometimes be straightened without surgery. Surgery choices include Phalangeal head resection (arthroplasty), in which the surgeon removes part of the toe bone. Joint fusion (arthrodesis), in which the surgeon removes part of the joint, letting the toe bones grow together (fuse). Cutting supporting tissue or moving tendons in the toe joint. How well surgery works depends on what type of surgery you have, how experienced your surgeon is, and how badly your toes are affected.
