Overview
The 2nd toe is the most common digit to develop a Hammer toes deformity. Second toe hammer toes hammertoe commonly result from an elongated 2nd metatarsal and from pressure due to an excessively abducted great toe (hallux valgus deformity) causing a bunion. Unusually long toes often develop hammer toe deformities. Painful corns often develop in hammer toe deformity, particularly of the 5th toe. Reactive adventitial bursas often develop beneath corns, which may become inflamed.
Causes
Hammertoes are a contracture of the toes as a result of a muscle imbalance between the tendons on the top of the toes (extensor tendons) and the tendons on the bottom of the toes (flexor tendons). If there is an imbalance in the foot muscles that stabilize the toe, the smaller muscles can be overpowered by the larger flexor and extensor muscles.
Symptoms
If you have any of these symptoms, do not assume it is due to hammer toe. Talk to your doctor about symptoms such as a toe that curls down, corns on the top of a toe, calluses on the sole of the foot or bottom of the toe, pain in the middle joint of a toe, discomfort on the top of a toe, difficulty finding any shoes that fit comfortably, cramping in a toe, and sometimes also the foot and leg, difficult or painful motion of a toe joint, pain in the ball of the foot or at the base of a toe.
Diagnosis
Although hammertoes are readily apparent, to arrive at a diagnosis the foot and ankle surgeon will obtain a thorough history of your symptoms and examine your foot. During the physical examination, the doctor may attempt to reproduce your symptoms by manipulating your foot and will study the contractures of the toes. In addition, the foot and ankle surgeon may take x-rays to determine the degree of the deformities and assess any changes that may have occurred.
Non Surgical Treatment
Wear sensible shoes. If you don?t want to have surgery to fix your hammertoe, use non-medicated padding along with proper shoes made with a wider and deeper toe box to accommodate your foot?s shape. Ensuring your shoes have a good arch support can slow the progression of the condition as well. Use a pumice stone. The corn or callus that forms on top of the hammertoe can cause discomfort when you wear shoes. Treat the corn by using a file or pumice stone to reduce its size after a warm bath, then apply emollients to keep the area softened and pliable. Use silicone or moleskin padding on top of the area when wearing shoes. Do foot exercises. Theoretically, exercises like extending, then curling the toes, splaying the toes, and moving the toes individually may help prevent the digital contracture that causes hammertoe. Try these suggestions and see what works best for you.
Surgical Treatment
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.
Daily modifications and correct shoe choices can prevent and slow the progression of hammertoe deformities. The main cause in hammertoe deformities is muscle/tendon dysfunction. Wearing of ill-fitting, tight, high heeled shoes contributes to the progression to hammertoe deformities. Also, bunion conditions can enhance the formation of hammertoes. A key to prevention of hammertoes is the wearing of correct footwear, specifically shoes with appropriate support and a deep, wide toe box.
