What actually is a hammer toe?

A hammer toe is a deformity of one of the lesser toes, most often the second, where the proximal interphalangeal joint sits in a fixed or semi-fixed flexed position. The tip of the toe points down, the middle knuckle of the toe points up, and the MTP joint at the base often sits in a slightly extended position. In the early phase the toe is flexible and can be straightened passively. Over time the joint capsule and tendons tighten and the deformity becomes rigid.

Why does this happen?

Several things combine. A long second toe crammed into a tight or pointed shoe toe box is a common mechanical driver. Hallux valgus deformity at the big toe can push the lesser toes into altered positions. Chronic imbalance between the long and short flexors of the toe, weak intrinsic foot muscles, and elevated heel footwear that concentrates load on the forefoot all contribute. In many cases the deformity develops slowly over years before pain or a visible callus brings the person in.

Can physiotherapy reverse a hammer toe?

That depends on whether the deformity is still flexible or has become rigid. Flexible hammer toes tend to respond reasonably well to a combination of footwear changes, intrinsic foot strengthening, toe splinting or taping, and addressing the broader forefoot mechanics that drove the problem. Rigid, fixed deformities do not straighten with conservative care. In those cases, the realistic goal of physiotherapy is to reduce pain, offload pressure points, preserve mobility in neighbouring joints, and help the person decide whether and when surgical consultation is appropriate.

What does the evidence actually show for conservative care?

Coughlin and colleagues' work on lesser toe deformities, and later reviews, are consistent that the evidence base for conservative management is limited and largely drawn from expert practice rather than large trials. What is reasonable is that footwear with a wide and deep toe box, strengthening of the intrinsic foot muscles, and toe splints or silicone sleeves to offload pressure can improve symptoms and slow progression in flexible deformities. I am honest with patients that the high-quality evidence for any one technique is thin, so the emphasis is on consistent, sensible mechanics rather than any single miracle exercise.

What kind of shoe should I be wearing?

A shoe with a wide, deep, and roughly foot-shaped toe box, a heel under about 2 cm, and flexibility through the forefoot. The aim is to give the toes room to sit in their natural spread rather than being squeezed into a tapered point. If a callus, corn, or blister is developing on the top of the toe from a shoe, the shoe is too shallow or too tight. I suggest patients walk around in shoes on a solid floor before buying, rather than trusting the size label alone.

When should I see a surgeon?

When the deformity is rigid, painful despite reasonable footwear and conservative care, associated with recurrent ulceration or infection (particularly in people with diabetes or peripheral neuropathy), or when it is interfering significantly with walking, work, or quality of life. Surgical options range from soft tissue procedures in more flexible cases to joint fusion or resection arthroplasty in rigid cases. The point of conservative care first is not to avoid surgery at all costs, it is to make sure surgery is actually needed before someone goes through it.

Will toe splints or crests actually help?

They can be useful adjuncts rather than a cure on their own. Silicone crests under the toes, gel sleeves over a painful PIP joint, and taping to gently straighten a flexible toe can reduce pressure and pain during the day. They work well when paired with shoe changes and foot strengthening. For a rigid toe, they are mostly about offloading and comfort rather than changing the shape of the joint.

Conditions with similar presentations:

Claw Toe Deformity

Key differences: Involves flexion at both the proximal and distal interphalangeal joints with extension at the , rather than the isolated PIP flexion of a true hammer toe. Often associated with neurological conditions or systemic disease, and tends to affect multiple toes symmetrically.

Mallet Toe Deformity

Key differences: Flexion at the distal interphalangeal joint only, with a normal proximal interphalangeal joint, unlike the PIP-dominant deformity of a hammer toe. Most often affects the second toe and often arises from pressure from an adjacent longer toe or a tight shoe toe box.

Morton's Neuroma

Key differences: Burning, electric, or shock-like pain in the with numbness into adjacent toes, rather than pain localised to a dorsal prominence over a flexed PIP joint. Symptoms are relieved by shoe removal and forefoot massage, and toe deformity may coexist but is not the primary driver of pain.

Metatarsophalangeal Joint Synovitis or Plantar Plate Injury

Key differences: Pain and swelling localised to the , often with a positive drawer test and a toe that is drifting or elevating, rather than a dorsal PIP prominence. injury most commonly involves the second toe and can progress to a crossover deformity.

Hallux Valgus with Secondary Lesser Toe Deformity

Key differences: Primary deformity at the first with lateral deviation of the great toe, which then crowds the lesser toes and can drive secondary hammer toe changes. Treatment focus often shifts toward the first ray rather than the lesser toe in isolation.
