Hammer Toe is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or orthotics. The usual cause is misalignment of the joint surfaces due to a genetic predisposition toward aberrant foot biomechanics and tendon contractures. RA and neurologic disorders such as Charcot-Marie-Tooth disease are other causes.
The muscles of each toe work in pairs. When the toe muscles get out of balance, a hammer toe can form. Muscle imbalance puts a lot of pressure on the toe's tendons and joints. This pressure forces the toe into a hammerhead shape. How do the toe muscles get out of balance? There are three main reasons. Your genes, you may have inherited a tendency to develop hammer toes because your foot is slightly unstable - such as a flat foot. But high-arched feet can also get hammer toes. Arthritis. Injury to the toe: ill-fitting shoes are the main culprits of this cause. If shoes are too tight, too short, or too pointy, they push the toes out of balance. Pointy, high-heeled shoes put particularly severe pressure on the toes.
The most obvious sign of hammertoes are bent toes, other symptoms may include pain and stiffness during movement of the toe. Painful corns on the tops of the toe or toes from rubbing against the top of the shoe's toe box. Painful calluses on the bottoms of the toe or toes. Pain on the bottom of the ball of the foot. Redness and swelling at the joints.
The treatment options vary with the type and severity of each hammer toe, although identifying the deformity early in its development is important to avoid surgery. Your podiatric physician will examine and X-ray the affected area and recommend a treatment plan specific to your condition.
Non Surgical Treatment
Wear wide shoes with plenty of room in the toes and resilient soles. Avoid wearing shoes with pointed toes. Commercially available felt pads or cushions may ease pressure from the shoe on the toe. Toe caps (small, padded sleeves that fit around the tip of the toe) may relieve the pain of hammer toe. Do toe exercises, to help toe muscles become stronger and more flexible.Arch supports or an orthotic shoe insert prescribed by your doctor or podiatrist may help to redistribute weight on the foot. These devices do not cure the problem but may ease the symptoms of either hammer toe or mallet toe.
Ordinary hammertoe procedures often use exposed wires which extend outside the end of toes for 4-6 weeks. Common problems associated with wires include infection where the wires come out of the toe, breakage, pain from hitting the wire, and lack of rotational stability causing the toe to look crooked. In addition, wires require a second in-office procedure to remove them, which can cause a lot of anxiety for many patients. Once inserted, implants remain within the bone, correcting the pain and deformity of hammertoes while eliminating many of the complications specific traditional treatments.
