When I was a child, my mother used to determine if a shoe fits by feeling for the position of my big toe through the tip of the shoe, alas, my second toe ended up getting scrunched by too small shoes and now I have slight hammer toes on second toes of both feet. Thankfully there is no pain or walking issues with this deformity.
Morton’s toe, sometimes referred to as Morton’s foot, is a common anatomical variation where the second toe is longer than the big toe (the hallux). Though often benign, this condition can lead to various complications and discomfort. Named after Dr. Dudley J. Morton, who described it in the early 20th century, Morton’s toe can affect one’s biomechanics, influencing the way a person walks and stands.
Anatomy of Morton’s Toe The condition is characterized by an elongated second metatarsal (the bone that connects to the second toe) relative to the first metatarsal (the one connected to the big toe). The apparent length difference is due to the relative positioning of the metatarsal bones, rather than the toes themselves. As a result, the second toe appears longer than the first.
Morton’s toe is found in roughly 20-30% of the population, though its exact prevalence varies across different studies. It is also more common in certain ethnic groups, particularly among individuals of European descent.
Causes and Biomechanical Implications Morton's toe is often an inherited trait, passed down genetically. Although having a longer second toe may seem like a minor physical quirk, it can have significant effects on foot mechanics. This is because the big toe is crucial for maintaining balance and supporting weight during walking. In individuals with Morton’s toe, the second toe or the associated metatarsal ends up bearing more pressure and stress than the big toe, which can lead to a chain of biomechanical problems.
Gait Issues: The distribution of weight during walking shifts toward the second metatarsal, leading to altered foot mechanics. This can result in a less stable gait and increased strain on the muscles, ligaments, and joints in the foot, ankle, and even further up the kinetic chain to the knees, hips, and back.
Calluses and Corns: Morton’s toe can lead to increased pressure on the ball of the foot beneath the second toe. This can cause calluses or corns to form as the body responds to the excess friction and stress.
Metatarsalgia: This condition, characterized by pain and inflammation in the ball of the foot, is commonly associated with Morton’s toe. It occurs when the second metatarsal absorbs more shock and pressure than it’s designed to handle, leading to pain in the metatarsal head.
Bunions and Other Deformities: Morton’s toe can contribute to the development of bunions, a bony bump that forms on the joint at the base of the big toe. Over time, the misalignment of pressure may cause the big toe to shift inward toward the other toes, leading to discomfort and deformity.
Plantar Fasciitis: Because Morton’s toe affects how weight is distributed across the foot, it can place additional strain on the plantar fascia, the ligament that runs along the bottom of the foot. This strain can result in plantar fasciitis, a condition marked by sharp heel pain.
Knee, Hip, and Back Pain: The altered foot mechanics caused by Morton’s toe can create a domino effect of problems higher up in the body. Because the body tries to compensate for the imbalance in the foot, improper alignment and posture can lead to pain in the knees, hips, and lower back.
Diagnosis Morton’s toe can be diagnosed during a physical examination by a podiatrist or orthopedic specialist. The doctor will observe the length of the toes and assess any symptoms that might be associated with the condition, such as foot pain or calluses. Imaging studies like X-rays may also be used to confirm the diagnosis by revealing the relative lengths of the metatarsal bones.
Orthotics and Insoles: Custom-made orthotics or over-the-counter shoe inserts can help redistribute weight more evenly across the foot, alleviating pressure on the second toe and the associated metatarsal. Metatarsal pads, in particular, can help reduce pressure on the ball of the foot.
Proper Footwear: Wearing shoes with ample toe room and cushioning can help mitigate the effects of Morton’s toe. Avoiding high heels or shoes with a narrow toe box is important, as they can exacerbate the pressure on the second toe and lead to further problems.
Stretching and Strengthening Exercises: Physical therapy exercises aimed at stretching and strengthening the muscles in the foot and lower leg can improve overall foot function and reduce pain. Stretching the calf muscles and plantar fascia may relieve some of the strain caused by altered gait mechanics.
Toe Spacers and Padding: Toe spacers can help realign the toes and prevent deformities like bunions from worsening. Padding around the toes can also reduce friction and protect against calluses.
Medications: Over-the-counter pain relievers such as ibuprofen can help reduce inflammation and alleviate pain associated with conditions like metatarsalgia or plantar fasciitis.
Surgery: In severe cases where conservative treatments fail to provide relief, surgery may be considered. Procedures such as shortening the second metatarsal or correcting bunions may help restore normal foot mechanics and relieve pain.
Living with Morton’s Toe
Most people with Morton’s toe can lead normal, active lives without significant limitations. The key to managing symptoms is addressing biomechanical imbalances early and adopting supportive footwear and inserts as needed. Maintaining strong, flexible muscles in the foot and lower leg can also help prevent pain from developing.
People with Morton’s toe should pay attention to any signs of foot pain, discomfort, or deformity, and seek medical attention if symptoms persist. Regular check-ups with a podiatrist can help prevent complications and ensure that the condition is managed effectively.
Morton’s toe is a common foot condition that can have far-reaching effects on biomechanics and overall foot health. While it is often harmless, the altered weight distribution can lead to various problems, from calluses and corns to more serious conditions like plantar fasciitis and bunions. Understanding how to manage Morton’s toe with proper footwear, orthotics, and exercises is key to maintaining comfort and preventing long-term complications.
