Hammer toe is caused when the middle joint (PIP) bends down towards the floor (flexion). To compensate, the joints above and below (MTP, DIP) bend up (hyperextend). The result is that the middle part of the toe lifts up. Hammertoe is the most common deformity of the lesser toes (i.e. not the big toe). It tends to only affect one toe, most commonly the second.
Most hammertoes are caused by wearing ill-fitting, tight or high-heeled shoes over a long period of time. Shoes that don?t fit well can crowd the toes, putting pressure on the middle toes and causing them to curl downward. Other causes include genes. Some people are born with hammertoe, bunions. These knobby bumps sometimes develop at the side of the big toe. This can make the big toe bend toward the other toes. The big Hammer toe toe can then overlap and crowd the smaller toes. Arthritis in a toe joint can lead to hammertoe.
A hammertoe may be present but not always painful unless irritated by shoes. One may have enlarged toe joints with some thickened skin and no redness or swelling. However, if shoes create pressure on the joint, the pain will usually range from pinching and squeezing to sharp and burning. In long standing conditions, the dislocated joints can cause the pain of arthritis.
Hammer toes may be easily detected through observation. The malformation of the person’s toes begin as mild distortions, yet may worsen over time – especially if the factors causing the hammer toes are not eased or removed. If the condition is paid attention to early enough, the person’s toes may not be permanently damaged and may be treated without having to receive surgical intervention. If the person’s toes remain untreated for too long, however the muscles within the toes might stiffen even more and will require invasive procedures to correct the deformity.
Non Surgical Treatment
For hammertoes that are still flexible, a podiatrist might recommend padding or taping the toes to relieve pain and orthotic inserts for shoes to minimize pressure and keep the toe properly aligned. Anti-inflammatory drugs or corticosteroid injections can relieve pain and inflammation. For more advanced cases of hammertoe, a podiatrist might recommend a surgical procedure to cut the tendon, allowing the toe to straighten. For hammertoes that have become rigid, a more complicated surgery might be needed, during which the podiatrist removes part of the bone at the deformed joint to allow it to straighten.
Surgery is the approach that is often necessary to correct hammertoe that fails to respond to nonsurgical management. Surgery is appropriate when the muscles and tendons involved in a hammertoe problem have become so tight that the joints are rigid, misaligned and unmovable. There are a number of surgical techniques for dealing with the complex range of joint, bone, muscle, tendon and ligament abnormalities that define each hammertoe’s make-up. To correct a hammertoe deformity, the surgeon’s goal is to restore the normal alignment of the toe joint, relieving the pressure that led to the hammertoe’s development (this should also relieve the pain, as well). To do this, he or she may remove part of the boney structure that creates a prominence at the top of the joint. Tighten or loosen the muscles, tendons and ligaments around the toe joints. Realign the toe bones by cutting one or more and shifting their position, realigning muscles, tendons and ligaments accordingly. Use screws, wires or plates to hold the joint surfaces together until they heal. Reconstruct a badly damaged joint or replace it with an artificial implant.
