Overview
Hammer toes is a Z-shaped deformity caused by dorsal subluxation at the metatarsophalangeal joint. Diagnosis is clinical. Treatment is modification of footwear and/or Hammer toes 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.
Causes
Your toe contains two joints that allow it to bend at the middle and bottom. A hammertoe occurs when the middle joint becomes dislocated. Common causes of this joint dislocation include a toe injury, arthritis, a high foot arch, wearing shoes that don?t fit properly, tightened ligaments or tendons in the foot, pressure from a bunion (when your big toe points inward toward your second toe) Spinal cord or peripheral nerve damage may cause all of your toes to curl downward.
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
First push up on the bottom of the metatarsal head associated with the affected toe and see if the toe straightens out. If it does, then an orthotic could correct the problem, usually with a metatarsal pad. If the toe does not straighten out when the metatarsal head is pushed up, then that indicates that contracture in the capsule and ligaments (capsule contracts because the joint was in the wrong position for too long) of the MTP joint has set in and surgery is required. Orthotics are generally required post-surgically.
Non Surgical Treatment
If your hammertoe problem is diagnosed as flexible hammertoe, there are a number of nonsurgical treatments that may be able to straighten out your toe or toes and return them to their proper alignment. Padding and Taping. Your physician may pad the boney top-part of your hammertoe as a means of relieving pain, and may tape your toes as a way to change their position, correct the muscle imbalance and relieve the pressure that led to the hammertoe's development. Medication. Anti-inflammatory drugs such as aspirin and ibuprofen can help deal with inflammation, swelling and pain caused by your hammertoe. Cortisone injections may be prescribed for the same purpose. If your hammertoe is a consequence of arthritis, your physician may prescribe medications for that.
Surgical Treatment
If your hammer, claw, or mallet toe gets worse, or if nonsurgical treatment does not help your pain, you may think about surgery. The type of surgery you choose depends on how severe your condition is and whether the toe joint is fixed (has no movement) or flexible (has some movement). A fixed toe joint often requires surgery to be straightened. A flexible toe joint can sometimes be straightened without surgery. Surgery choices include Phalangeal head resection (arthroplasty), in which the surgeon removes part of the toe bone. Joint fusion (arthrodesis), in which the surgeon removes part of the joint, letting the toe bones grow together (fuse). Cutting supporting tissue or moving tendons in the toe joint. How well surgery works depends on what type of surgery you have, how experienced your surgeon is, and how badly your toes are affected.
