splayfoot

What is splayfoot?

With splayfoot, the transverse arch of the forefoot lowers. This causes the metatarsals to move apart; the load is distributed unfavorably, often on the second and third metatarsal heads. This can lead to pressure pain, calluses, corns and irritation of nerves and soft tissues.

• Lowered transverse arch of the forefoot
• Separation of the metatarsal bones
• Peak loads under the metatarsal heads (metatarsalgia)
• Common accompanying changes: hammer or claw toes, hallux valgus tendency

Splayfoot is usually acquired and develops gradually. Early relief and training can significantly reduce symptoms and slow progression.

Anatomy and biomechanics of the forefoot

The foot has a longitudinal and a transverse arch. The transverse arch stretches over the metatarsal bones (metatarsalia) and is stabilized by ligaments, joint capsules and the short foot muscles. When the foot is splayed, this arch gives way; The transverse associations are overloaded and the plantar soft tissues (fat pads, plantar fascia) are subjected to increased stress.

• Transverse arch: distributes load to metatarsal heads 1–5
• Stabilizers: short foot muscles, plantar aponeurosis, transverse ligaments
• When sinking: increased pressure under the central metatarsal heads
• Compensations: Toe misalignment, forefoot width increases

Typical symptoms

Symptoms are often stress-related and increase over the course of the day. At first they only appear in tight or hard shoes, later also barefoot.

• Pressure and burning pain under the metatarsal heads (metatarsalgia)
• Calluses, corns or redness on the forefoot
• Tingling, numbness or shooting pain between the toes (nerve irritation/Morton's neuroma possible)
• Increasing forefoot width – press shoes
• Pain when rolling, rare pain at rest with pronounced inflammation

If left untreated, poor posture can occur when walking, which puts additional strain on the knees, hips or back.

Causes and risk factors

Splayfoot usually has several causes. In addition to connective tissue and muscle insufficiency, external influences and other foot axes play a role.

• Footwear: tight, hard or high-heeled shoes increase forefoot pressure
• Prolonged standing or walking activities
• Excess weight – higher load peaks in the forefoot
• Anatomical axes: Arched arches or flat feet can put additional strain on the forefoot
• Weak connective tissue, familial predisposition
• Pregnancy and hormonal changes
• Post-traumatic, after operations or in neurological diseases (rare)

Important: Not every wide forefoot is a splayfoot. The clinical examination and symptoms are crucial.

Frequent accompanying and subsequent problems

The redistribution of the load can result in further changes, which we include in the therapy planning.

• Metatarsalgia – stress-dependent pain under the metatarsal heads
• Hammer and claw toes due to tendon imbalance
• Hallux valgus tendency with medial bunion formation
• Morton's neuroma - painful thickening of a forefoot nerve
• Bursitis (bursitis) and soft tissue irritations

Diagnostics in practice

The diagnosis is based on anamnesis, clinical examination and – depending on the question – additional imaging. Our goal is to identify causes of complaints and stress patterns.

Differential diagnoses include: Stress fractures, arthrosis of the forefoot joints, tarsal coalition or neurological causes of pain.

Conservative therapy – the structured step-by-step plan

Most patients benefit from conservative measures. We combine shoe and insole advice with targeted training, everyday adjustments and – if necessary – temporary pain therapy.

• Shoe fitting: sufficiently wide, soft forefoot box; flexible sole; moderate sales
• Insole supply with forefoot pad to raise the transverse arch and redistribute pressure
• Padding/pressure protection in exposed areas, e.g. B. Soft bed under painful heads
• Physiotherapy: activation of the short foot muscles, gait training, mobilization of stiff joints
• Do your own exercises (see below) consistently 3-5 times a week
• Weight management in case of overload
• Short term: anti-inflammatory medications or ointments - only after informed consent and for a limited time if possible

Regenerative procedures (e.g. injections) are of limited importance for splayfoot and are used - if at all - individually and according to clear indications. The goal remains cause-oriented relief and stabilization.

Exercises for the transverse arch

Regular training strengthens the short foot muscles and supports the transverse arch. Perform the exercises slowly, pain-free to moderately pain-accepting and evenly on both sides.

Increase the volume and repetitions moderately. If symptoms increase, take a break and seek medical advice.

Shoes and insoles: what to pay attention to?

The right footwear is a central component of splayfoot. The aim is a low-pressure, stable and yet flexible rolling movement with enough space in the forefoot.

• Wide forefoot box, soft upper without hard seams
• Metatarsal pad in the insole to raise the transverse arch
• Soft bedding option under painful metatarsal heads
• A moderate heel of 1-2 cm can relieve the pressure on the forefoot - avoid high heels
• Consider rolling sole if metatarsalgia is severe
• Switch between multiple pairs to vary pressure peaks

Surgery – when does it make sense?

Surgery is considered if conservative measures do not bring about satisfactory improvement over a sufficiently long period of time and the quality of life is significantly reduced. The decision is individual and takes into account pain, function, accompanying deformities and professional requirements. Guaranteed success cannot be promised.

• Soft tissue interventions on capsules/tendons for misaligned toes
• Corrective osteotomies of the metatarsals (e.g. Weil osteotomy) to redistribute the load
• Combined forefoot reconstructions for severe findings
• Accompanying corrections for axial deviations (e.g. hindfoot or midfoot), if causally contributing

Depending on the procedure, partial weight-bearing, special shoes and physiotherapy are necessary for weeks after a forefoot operation. We discuss benefits, risks, alternatives and realistic goals in detail.

Course and prognosis

In many cases, symptoms can be significantly alleviated with consistent conservative treatment. The deformity itself is usually not completely corrected, but can be functionally stabilized.

• Early intervention improves the chances of success
• Consistently wearing appropriate insoles and shoes is crucial
• Exercise programs tend to have a medium to long-term effect
• Load control and weight reduction support the effect
• In advanced deformities, a surgical option should be considered if conservative options have been exhausted

Prevention and everyday tips

• Switch between different shoes in everyday life
• Only wear high-heeled, tight or hard shoes for short periods of time
• Integrate foot muscle training regularly
• Design your workplace ergonomically – alternate standing and walking phases
• Care for foot skin, relieve pressure points early
• If you have any initial complaints, seek orthopedic advice

When should you seek medical advice?

• Increasing forefoot pain despite wearing shoes that provide relief
• New numbness, burning pain between toes
• Signs of inflammation such as redness, overheating, swelling
• Sudden onset of stress-dependent pain after overexertion of sport (suspected stress fracture)
• Wounds or cracks in the skin, especially if you have diabetes
