Hammertoes Surgery

HammertoeOverview

A Hammer toes is commonly mistaken as any type of toe deformity. The terms claw toe, or mallet toe, although technically different than a hammer toe, are commonly referred as such. The toe may be flexible with movement at the joints, or it may be rigid, especially if it has been present for a long time. With a true hammertoe the deformity exists at the proximal interphalangeal joint only.

Causes

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.

Hammer ToeSymptoms

People with a hammer toe will often find that a corn or callus will develop on the top of the toe, where it rubs against the top of the footwear. This can be painful when pressure is applied or when anything rubs on it. The affected joint may also be painful and appear swollen.

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

Podiatric Care may include using anti-inflammatory oral medications or an injection of medication and local anesthetic to reduce this swelling. When you go to your doctor, x-rays are usually required to evaluate the structure of your foot, check for fractures and determine the cause. The podiatrist may see you to take care of any corns that develop due to the bone deformities. They may advise you on different shoewear or prescribe a custom made orthotic to try and control the foot structure. Padding techniques may be used to straighten the toe if the deformity is flexible, or pads may be used to lessen the pressure on hammertoe the area of the corn or ulcer. Your podiatric physician may also recommend a surgical procedure to actually fix the structural problem of your foot.

Surgical Treatment

Extreme occurrences of hammer toe may call for surgery. Your surgeon will decide which form of surgery will best suit your case. Often, the surgeon may have to cut or remove a tendon or ligament. Depending on the severity of your condition, the bones on both sides of the joint afflicted may need to be fused together. The good news is you can probably have your surgery and be released to go home in one day. You will probably experience some stiffness in your toe, but it might last for a short period, then your long-term pain will be eliminated.
