Hammer, Claw & Mallet Toes Physiotherapy Brisbane southside.
What are hammer, claw and mallet toes?
Hammer, claw and mallet toes are three distinct but related toe deformities involving abnormal flexion contractures of the interphalangeal joints. All three reflect an imbalance between the intrinsic muscles of the foot — the small muscles within the foot that extend the toe joints — and the extrinsic muscles — the longer muscles originating in the leg that flex the toes. When the intrinsic muscles are weakened or dysfunctional, the extrinsic flexors overpower them, pulling the toes into characteristic bent positions.
Hammer toe involves flexion of the proximal interphalangeal (PIP) joint — the middle joint of the toe — with the distal joint and metatarsophalangeal (MTP) joint relatively normal. The toe adopts an inverted V shape, with the bent PIP joint rubbing against the top of footwear. The second toe is most commonly affected.
Claw toe involves hyperextension of the MTP joint — the knuckle joint at the base of the toe — combined with flexion of both the PIP and distal interphalangeal (DIP) joints. The toe curls downward like a claw. Claw toe affects multiple toes simultaneously more often than hammer toe and is more frequently associated with neurological conditions — peripheral neuropathy, Charcot-Marie-Tooth disease and other conditions causing intrinsic muscle weakness can all produce claw toe deformity.
Mallet toe involves flexion of only the DIP joint — the end joint of the toe — with the upper joints relatively normal. Common symptoms of mallet toes include pain, corns or calluses on the tip of the affected toe, difficulty extending or straightening the toe joint, and the toe's bent appearance.
Flexible versus rigid deformities
The most clinically important distinction for management is whether the deformity is flexible — the joint can be passively straightened to neutral — or rigid, where the joint has contracted and can no longer be passively corrected. Flexible deformities respond well to conservative management including physiotherapy, orthotics and footwear modification. Rigid deformities that are painful and not responding to conservative management may require surgical correction to straighten the joint. Early management of flexible deformities significantly reduces the risk of progression to rigid contracture.
What causes these deformities?
Treatment options for these toe deformities include wearing shoes with a roomy toe box, using cushioned toe caps or splints, performing exercises to strengthen toe muscles, and considering surgical correction in severe cases.
The underlying mechanism is intrinsic muscle weakness combined with the mechanical environment of poorly fitting footwear. Shoes with narrow toe boxes force the toes into sustained flexion, gradually stretching the dorsal capsular structures and shortening the plantar structures. High heels further compound the problem by loading the forefoot and placing the toe extensors at a mechanical disadvantage.
Flat feet and bunions (hallux valgus) alter forefoot biomechanics and are common associated findings — as the hallux deviates toward the second toe, it displaces the second toe upward, predisposing it to hammer toe formation. Rheumatoid arthritis commonly produces claw toe deformity through synovitis and intrinsic muscle atrophy. Peripheral neuropathy produces claw toes through denervation of the intrinsic muscles.
How can physiotherapy help?
Physiotherapy can be beneficial in managing hammer toes, claw toes, and mallet toes by addressing associated pain, discomfort, and functional limitations, as well as providing strategies to improve toe alignment and flexibility. A physiotherapist will conduct a thorough assessment to determine the extent of the toe deformity and its impact on foot function, assessing muscle strength, flexibility, and gait to identify contributing factors.
Intrinsic foot muscle strengthening is the most important exercise intervention — specifically the lumbricals and interossei, which extend the interphalangeal joints while flexing the MTP joints. Towel scrunching, toe spreading, marble picking exercises and short foot exercises progressively rebuild intrinsic foot muscle strength and restore the muscle balance that resists deformity progression. These exercises are most effective for flexible deformities in the early stages.
Toe stretching — particularly passive dorsiflexion of the affected joints — maintains range of motion and prevents progression toward rigid contracture. Manual manipulation of the affected joints and soft tissue work in the plantar foot and intrinsic muscles complement the exercise program.
Orthotic management is a central component — custom or semi-custom orthotics with toe props, metatarsal pads and forefoot corrections redistribute plantar pressure away from the painful areas and provide mechanical correction of the deforming forces. Toe splints worn during the day or night maintain joint position and slow deformity progression in flexible cases.
Footwear assessment and advice is equally important — no amount of physiotherapy will produce lasting improvement if the patient continues wearing shoes with narrow toe boxes or high heels. Wide toe box shoes with adequate depth are essential.
Corns and calluses — which form at the friction points on the top of the bent PIP joint (hammer toe), the tip of the toe (mallet toe) and the MTP joint (claw toe) — are managed with padding, debridement and pressure redistribution. Physiotherapy addresses the underlying mechanical cause rather than just treating the corn itself.
Clinical Pilates provides a useful environment for foot and lower limb strengthening including intrinsic foot muscle work in the context of the broader lower limb mechanics contributing to forefoot loading. Gait retraining addresses any walking pattern abnormalities that are contributing to excessive forefoot loading.
Our physiotherapists Eliane Machado and Yulia Khasyanova both have experience in foot and ankle conditions and are members of the Australian Physiotherapy Association. Eliane's doctoral research in lower limb biomechanics is directly relevant to the gait and forefoot loading analysis underpinning toe deformity management.
