A hammer toe is a common foot deformity that occurs when the second, third, or fourth toe bends at the middle joint, causing it to curl downward in a characteristic, hammer-like shape. This deformity results from an imbalance in the muscles, tendons, or ligaments that are meant to hold the toe straight. The appropriate approach to treatment is primarily determined by whether the toe is flexible, meaning it can still be manually straightened, or fixed, where the joint has become rigid and immobile.
Immediate Non-Invasive Strategies
Addressing a flexible hammer toe quickly can prevent the condition from progressing to a rigid state. The most direct line of defense involves modifying the shoes worn daily. Shoes should feature a deep and wide toe box to provide ample room for the toes. Avoid high-heeled footwear, as these designs shift body weight forward, forcing the toes into the front of the shoe and exacerbating the joint bend.
For existing discomfort, non-medicated padding and cushioning can be applied to alleviate pressure and reduce friction against the shoe. Using soft gel cushions or felt pads over the bent joint protects the prominent area and helps prevent the formation of painful corns or calluses. These measures reduce irritation and make walking more comfortable.
Another simple, self-managed technique involves taping or strapping the affected toe. Medical tape can be used to gently hold the hammer toe in a straighter alignment by binding it to an adjacent, non-deformed toe. This provides external support and encourages the toe to maintain a flatter position, which helps reduce the tension on the contracted tendons.
Regular, targeted foot and toe exercises maintain joint flexibility and strengthen the small muscles of the foot. Simple actions, like using the toes to pick up small objects (such as marbles) or scrunching a towel, help restore muscle balance and improve range of motion. Consistent performance of these exercises counteracts the muscle imbalance that contributes to the toe’s curling.
When Conservative Measures Fail
When home care strategies fail to manage the pain or halt the progression of the deformity, professional help is necessary to explore advanced non-surgical options. A podiatrist or orthopedic specialist can assess the severity, determining if the toe is still flexible or if the joint has become fixed and rigid. This assessment is crucial because rigid hammer toes are far less responsive to conservative measures.
Custom orthotics or arch supports are commonly recommended. These prescription inserts are molded specifically to the contours of the patient’s foot. They function by correcting underlying biomechanical issues, such as flat feet or high arches, which contribute to the muscle imbalance that causes the toe deformity. By redistributing pressure, orthotics relieve stress on the toes and prevent the condition from worsening.
Specialized splinting or bracing devices provide a more rigid and customized form of external support than simple taping. These prescription devices are often worn at night or inside wider footwear to hold the toe in a corrected position for longer periods. They encourage the toe to return to a more anatomical alignment and protect it from further abnormal bending.
If gait abnormalities or muscle weakness are identified as contributing factors, a physician may refer the patient for physical therapy. A therapist performs a detailed gait analysis to identify improper walking mechanics and then develops a targeted program. This program focuses on specific strengthening and stretching exercises to improve the balance between the flexor and extensor tendons.
Surgical Options for Permanent Correction
Surgery is reserved for cases where the hammer toe is rigid, conservative measures have failed to provide relief, and the pain restricts daily activities. The goal of surgical correction is to straighten the toe permanently and eliminate the friction caused by the bent joint. The choice of procedure depends on the severity and rigidity of the deformity.
One common procedure is Joint Arthroplasty, also called a resection arthroplasty. During this surgery, a small portion of the bone from the proximal interphalangeal joint (PIPJ) is removed. This resection creates a gap, allowing the toe to straighten and relieve tension on the contracted joint capsule and tendons. This technique leaves some degree of movement in the toe, though it may result in a slightly shorter toe.
Alternatively, a surgeon may perform a Proximal Interphalangeal Joint (PIPJ) Fusion, known as arthrodesis, which is preferred for more severe or recurrent deformities. This involves removing the cartilage surfaces from the joint and permanently joining the two bone ends. This procedure creates a rigid, stable toe that acts as a strong lever during walking. Fixation is achieved using small hardware, such as a temporary wire (Kirschner wire) or an internal screw/implant, until the bone heals completely.
Soft tissue procedures are often performed with bone correction but can be used alone for less severe, flexible hammer toes. These procedures involve lengthening or transferring the tendons that pull the joint into the bent position. A Tendon Lengthening or tenotomy releases the tight tendon, while a Tendon Transfer reroutes a tendon to provide better leverage for straightening the toe.
Post-operative care is a significant component of recovery. Patients are typically placed in a surgical shoe or boot immediately following the operation to protect the toe. If a Kirschner wire is used for fixation, it usually remains in place for three to six weeks before being removed in the doctor’s office. Full recovery, including the resolution of swelling and stiffness, can take several months, but most patients return to normal activities within six to eight weeks.
