What Causes Claw Toes and How They Differ From Hammertoes

Common Causes of Claw toe causes
The toes are controlled by an intricate system of tendons, muscles, and ligaments that must work in precise balance to keep them straight and functional. When this balance is disrupted, the toes can contract into abnormal positions that become progressively more rigid over time. Claw toes and hammertoes are two of the most common toe deformities, and while they may look similar at a glance, they are anatomically distinct conditions with different underlying causes.
A hammertoe is characterized by a flexion deformity at the proximal interphalangeal (PIP) joint, the middle knuckle of the toe. The toe bends downward at this joint while the metatarsophalangeal (MTP) joint at the base of the toe is often extended or neutral. The second toe is the most commonly affected, and the deformity is frequently associated with bunions, which push the second toe out of alignment.
A claw toe, by contrast, involves abnormal positioning at two joints simultaneously. The MTP joint at the base of the toe is hyperextended while both the PIP and distal interphalangeal (DIP) joints are flexed, causing the toe to curl downward into a claw-like position. This pattern gives the foot an appearance somewhat like fingers gripping an object and represents a more severe disruption of toe mechanics than a simple hammertoe.
Claw toes are most commonly associated with neurological conditions that affect the small intrinsic muscles of the foot. Conditions such as Charcot-Marie-Tooth disease, diabetic peripheral neuropathy, cerebral palsy, and stroke can all weaken the intrinsic foot muscles, allowing the extrinsic muscles that run from the lower leg to dominate toe positioning. This muscle imbalance pulls the toes into the characteristic claw configuration.
Hammertoes, on the other hand, have a stronger association with mechanical and structural factors such as wearing shoes that are too short, narrow, or pointed. High-heeled shoes that force the forefoot into a cramped toe box are a particularly common contributing factor in women. Flatfoot deformity, which alters the mechanical advantage of the tendons around the toes, also increases the risk of hammertoe development over time.
Signs and Symptoms to Watch For
Both conditions exist on a spectrum from flexible to rigid. In the early stages, the deformity can be passively corrected by pressing the toe back into a straightened position with the fingers. As the condition progresses, the soft tissues shorten and the joints become contracted, making passive correction no longer possible. Flexible deformities have significantly more conservative treatment options available than rigid ones.
The clinical problems created by claw toes and hammertoes extend beyond cosmetic concerns. The prominent knuckles of hammertoes rub against the tops of shoes, creating painful corns and calluses on the dorsal surface of the toe. Claw toes may develop calluses on the tips of the toes where they dig into the ground during walking. Both conditions can cause pain at the ball of the foot as the MTP joint is stressed by the altered toe position.

For flexible deformities, conservative management includes padding and protective sleeves to cushion the prominent joints, splinting or taping exercises to encourage straightening, and switching to deeper toe box footwear that reduces direct pressure. Physical therapy exercises aimed at strengthening the intrinsic muscles and stretching the flexor tendons can slow deformity progression in early-stage cases.
Custom foot orthotics address the underlying mechanical imbalances that contribute to hammertoe and claw toe formation. A toe crest pad or metatarsal pad incorporated into an orthotic can offload pressure from the ball of the foot and provide a physical prop under the toes to discourage curling. For patients with neurological claw toes, orthotics with toe channels can also protect the toe tips from ground impact.
Surgical correction is considered when conservative measures no longer provide adequate pain relief or when the deformity has become rigid and is causing significant functional impairment. Hammertoe surgery typically involves releasing or lengthening the contracted tendons and straightening the PIP joint, sometimes with a small pin or implant used to hold the correction while healing occurs. Claw toe surgery is more complex because it addresses multiple joint levels simultaneously.
Treatment Options at Thrive Foot and Ankle
Recovery from toe deformity surgery varies based on the number of toes treated and the techniques used. Most patients are able to walk in a surgical shoe immediately after the procedure, with a return to regular footwear in four to six weeks. Swelling may persist for several months, and the final cosmetic and functional result continues to evolve throughout the first year after surgery.
For patients with neurological causes of claw toe, treating the underlying condition and optimizing foot muscle support are the primary goals, as surgery addresses the mechanical consequence rather than the root cause. A coordinated approach involving neurology and podiatry ensures that the toe correction is durable and that appropriate protective measures are in place for the long term.
If you notice your toes beginning to curl or contract, or if you have corns and calluses that keep returning despite trimming and padding, a podiatric evaluation can determine whether a deformity is beginning to develop and how best to address it while treatment options are still broad. Early intervention for flexible deformities yields substantially better results than waiting until the condition has become rigid and surgical correction becomes the only option.
At Thrive Foot and Ankle, we evaluate and treat the full spectrum of toe deformities with both conservative and surgical approaches tailored to your specific condition. Book an appointment online to find out which treatment is right for you.
