hammertoes 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.
Hammer toe is most often caused by wearing compressive shoes. It might also be caused by the pressure from a bunion. A bunion is a corn on the hammertoes top of a toe and a callus on the sole of the foot develop which makes walking painful. A high foot arch may also develop.
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.
The earlier a hammertoe is diagnosed, the better the prognosis and treatment options. Your doctor will be able to diagnose your hammertoe with a simple examination of the foot and your footwear. He or she may take an x-ray to check the severity of the condition. You may also be asked about your symptoms, your normal daily activities, and your medical and family history.
Non Surgical Treatment
Treatment for a hammertoe usually depends on the stage of the hammertoe and the cause of the condition. If your toe is still bendable, your doctor may suggest conservative care-relieving pressure with padding and strapping, or proper shoes that have a deep toe box and are of adequate length and width. Early intervention can often prevent the need for surgery.
Surgical correction is necessary in more severe cases and may consist of removing a bone spur (exostectomy) removing the enlarged bone and straightening the toe (arthroplasty), sometimes with internal fixation using a pin to realign the toe; shortening a long metatarsal bone (osteotomy) fusing the toe joint and then straightening the toe (arthrodesis) or simple tendon lengthening and capsule release in milder, flexible hammertoes (tenotomy and capsulotomy). The procedure chosen depends in part on how flexible the hammertoe is.
There should be at least one-half inch between the tip of your longest toe and the front of the shoe. Never buy shoes that feel tight and expect them to stretch with wearing. If you have prominent areas on your feet such as hammertoes and bunions, avoid shoes with a lot of stitching or multiple pieces of fabric, as these stitched areas tend not to stretch to accommodate various toe deformities.
