If you notice one day that one of your toes is noticeably shorter than the others, or appears “pulled back” and out of line with the natural shape of your foot, you may be dealing with a condition called Brachymetatarsia.This condition is not just a simple cosmetic difference. It happens because one of the metatarsal bones in the foot is shorter than normal, which can affect the appearance of the foot while standing or walking. In some cases, it may also cause discomfort or make it difficult to find comfortable shoes.Although many people consider it mainly a cosmetic issue rather than a serious medical condition, understanding its causes and treatment options can make it much easier to manage—especially if the symptoms begin to appear or become more bothersome over time.In this article from Dalili Medical, we’ll explore everything you need to know about short toe syndrome (Brachymetatarsia), including its causes, symptoms, diagnosis, and the latest available treatment options, in a simple and easy-to-understand way.

What Is Brachymetatarsia (Short Metatarsal Bone)?

Brachymetatarsia is a rare congenital condition caused by the premature closure of the growth plate in one of the metatarsal bones of the foot. This results in one toe appearing noticeably shorter than the others. In nearly 90% of cases, the fourth toe is the most commonly affected. The condition is more common in females and usually becomes noticeable during childhood or puberty. In some cases, surgical treatment may be recommended to lengthen the bone and improve both the appearance and function of the foot.

Is Brachymetatarsia a Serious Condition?

No, in most cases, Brachymetatarsia is not considered medically dangerous. However, it may cause cosmetic concerns related to the appearance of the foot and, in some people, may lead to discomfort, pain, or difficulty while walking.

Is Brachymetatarsia Hereditary?

Yes, in many cases the condition is congenital or hereditary. It often appears during childhood or while the foot is developing.

Does Brachymetatarsia Worsen Over Time?

Usually, the condition remains stable after bone growth is complete. However, symptoms may become more noticeable over time if excessive pressure is placed on the foot or if unsuitable footwear is used.

Can You Live with the Condition Without Treatment?

Yes, many people live normally with Brachymetatarsia without needing treatment, especially if there is no pain or significant effect on walking or daily activities.

When Is Surgery Needed?

Surgery for Brachymetatarsia may be recommended in the following situations:

• Persistent or bothersome pain
• Difficulty walking or wearing shoes comfortably
• Significant cosmetic concerns causing emotional discomfort or dissatisfaction with the appearance of the foot

Is the Surgery Dangerous?

The procedure is generally considered safe, like most orthopedic surgeries. However, some minor complications may occur, such as:

• Temporary stiffness in the toe or foot joints
• Pain during the recovery period
• Delayed bone healing in some cases

Can High Heels Be Worn After Surgery?

Yes, high heels can usually be worn after complete recovery. However, this should be done gradually and according to the surgeon’s recommendations to ensure proper bone healing and avoid complications.

Does the Condition Affect Movement or Sports?

In mild cases, the condition usually does not affect movement or daily activities.
In more severe cases, it may cause discomfort or pain during walking, running, or sports activities, especially when extra pressure is placed on the foot.

Types of Brachymetatarsia

Brachymetatarsia can be classified based on the affected bone, the number of toes involved, the underlying cause, and the severity of the condition. This classification helps doctors determine the best treatment approach.

First: According to the Affected Bone

1. First Metatarsal Shortening (Big Toe)

• Affects the bone beneath the big toe
• Considered less common
• May affect foot balance during walking

2. Fourth Metatarsal Shortening (Most Common)

• Usually affects the fourth toe
• The toe appears shorter or pulled backward
• Easily noticeable while standing or walking

3. Multiple Metatarsal Shortening

• Involves more than one metatarsal bone
• Causes a more obvious change in foot shape
• May affect weight distribution while walking

Second: According to the Number of Affected Feet

1. Unilateral Type

• Affects only one foot
• The most common form

2. Bilateral Type

• Affects both feet
• Often associated with hereditary or congenital factors

Third: According to the Cause

1. Congenital

• Present since birth
• Usually linked to genetic factors or abnormal bone development

2. Acquired

• Develops after birth
• May result from injury to the growth plate or bone disorders

Fourth: According to Severity

• Mild: Slight difference in toe length
• Moderate: Clearly visible shortening
• Severe: Significant shortening that may affect appearance and walking

Causes of Brachymetatarsia

Brachymetatarsia occurs when one or more of the metatarsal bones are shorter than normal, causing one toe to appear shorter or recessed compared to the others. The causes may include:

1. Genetic Causes (Most Common)

Many cases are congenital or hereditary, meaning the child is born with abnormal bone development in the foot. The condition often becomes noticeable during childhood or as the foot grows.

2. Premature Closure of the Growth Plate

The growth plate responsible for bone lengthening may stop developing too early, causing the bone to remain shorter than normal. In some cases, this happens without a clear reason.

3. Hormonal Disorders

Certain hormonal problems, such as growth hormone disorders or parathyroid gland disorders, can affect bone growth and contribute to shortening of the metatarsal bones.

4. Childhood Injuries

Fractures or injuries affecting the growth plate during childhood may interfere with normal bone growth and lead to metatarsal shortening.

5. Congenital Syndromes and Bone Disorders

Some rare genetic syndromes are associated with bone deformities, and Brachymetatarsia may be one of their features.

6. Unknown Causes (Idiopathic)

In some cases, no clear cause can be identified, and the condition is discovered incidentally or through noticing the appearance of the foot.

Symptoms of Brachymetatarsia

In many cases, Brachymetatarsia is more noticeable because of the foot’s appearance rather than pain. Symptoms vary depending on the severity of the shortening and its effect on walking.

1. Noticeably Short Toe

This is the most common symptom. One toe appears shorter than the others and may seem pulled backward or “sunken” compared to the surrounding toes.

2. Changes in the Shape of the Front of the Foot

The front of the foot may appear uneven or asymmetrical, especially while standing or wearing open shoes or sandals.

3. Pain While Walking or Standing

Pain does not occur in every case, but severe forms may cause discomfort due to uneven pressure distribution on the foot.

4. Difficulty Choosing Comfortable Shoes

Some people experience discomfort while wearing tight or closed shoes because of the unusual toe alignment and imbalance inside the shoe.

5. Uneven Weight Distribution on the Foot

This may lead to:

• Stress and pressure on the metatarsal area
• Development of thickened skin or calluses in certain areas
• Sometimes heel pain or pain in the sole of the foot due to changes in walking mechanics

6. Psychological or Cosmetic Impact

Especially in women, the appearance of the foot may cause embarrassment when wearing open shoes or sandals, which can sometimes affect self-confidence.

Diagnosis of Brachymetatarsia (Short Metatarsal Bone)

Diagnosing Brachymetatarsia is usually relatively straightforward. It mainly depends on a clinical examination along with X-rays to accurately determine the degree of shortening and identify the underlying cause.

First: Clinical Examination

The doctor begins by evaluating the condition through:

• Examining the appearance of the foot while standing and walking
• Checking for a toe that appears shorter or recessed compared to the others
• Assessing how body weight is distributed across the foot
• Asking about pain or difficulty wearing shoes

Second: X-rays

X-rays are considered the most important step in diagnosis because they help show:

• The length of the metatarsal bones compared to the surrounding bones
• The exact affected metatarsal bone
• The condition of the growth plate and whether bone growth stopped prematurely
• The severity of the shortening (mild, moderate, or severe)

Third: Bone Age Assessment

In some cases, the doctor may compare:

• The patient’s bone age
• With their actual age

This helps determine whether there is delayed or abnormal bone growth.

Fourth: Ruling Out Other Causes

The doctor also makes sure there are no other conditions causing similar symptoms, such as:

• Previous foot bone injuries
• Hormonal disorders affecting growth
• Rare congenital syndromes
• Structural deformities of the foot bones

Fifth: Evaluating the Impact of the Condition

Diagnosis is not based only on appearance. It also includes evaluating:

• Pain while walking or standing
• The effect on wearing shoes comfortably
• Cosmetic concerns and the patient’s level of discomfort about the appearance of the foot

Complications of Brachymetatarsia

Brachymetatarsia may lead to certain complications. These do not occur in every patient, but they are more likely in severe cases or when weight distribution on the foot is significantly affected.

1. Pain While Standing or Walking

Because of uneven pressure distribution on the front of the foot, patients may experience:

• Pain in the forefoot
• Excess strain on certain areas of the foot

2. Thickened Skin (Calluses)

Increased pressure on specific areas can lead to:

• Thick or hardened skin formation
• Skin cracks developing over time in some cases

3. Problems with Walking and Balance

Some patients may experience:

• Discomfort while walking
• A mild feeling of imbalance
• Subtle long-term changes in walking pattern or gait

4. Pain in Other Areas of the Lower Limb

Because the body tries to compensate for the imbalance in the foot, extra pressure may develop on:

• The heel
• The ankle
• Sometimes even the knee

5. Difficulty Wearing Shoes

Especially with tight or closed shoes, which may lead to:

• Friction while walking
• Pain when wearing shoes
• A general feeling of discomfort

6. Psychological and Cosmetic Effects

In some cases, especially among women, the appearance of the foot may cause:

• Embarrassment when wearing open shoes or sandals
• Avoidance of certain shoe styles
• Reduced self-confidence

7. Increased Visibility of the Deformity Over Time

If the condition is not monitored or treated when necessary:

• The foot deformity may become more noticeable
• Symptoms related to pain and pressure may gradually worsen

Medical Treatment for Brachymetatarsia

It is important to understand from the beginning that there are no medications capable of increasing bone length or permanently correcting the shortening itself, because the problem is related to bone growth and structure rather than inflammation or infection.

However, certain medications may help relieve symptoms and improve comfort.

1. Pain Relievers

If pain occurs while walking or standing, the following may be used:

• Paracetamol (Acetaminophen) for mild pain
• Nonsteroidal anti-inflammatory drugs (NSAIDs) such as Ibuprofen, under medical supervision

The goal is to reduce pain, not treat the underlying bone shortening.

2. Anti-inflammatory Medications

In cases where stress or inflammation develops in the front of the foot due to uneven pressure, the doctor may prescribe:

• Short-term anti-inflammatory medications

These help reduce swelling and discomfort.

3. Topical Treatments (Creams and Gels)

Certain creams or topical gels may be used in cases involving:

• Localized pain in the front of the foot
• Thickened skin or calluses caused by pressure

However, their effect is limited and they do not treat the shortening itself.

4. Calcium and Vitamin D Supplements

In patients with deficiencies affecting bone health, the doctor may recommend:

• Vitamin D supplements
• Calcium supplements

These do not increase bone length but help support overall bone health.

Surgical Treatment for Brachymetatarsia

Surgery is considered one of the most effective treatment options for Brachymetatarsia, especially when the shortening is significant, painful, affects walking, or causes cosmetic concerns.

The main goal of surgery is to lengthen the shortened bone and restore the natural balance of the foot. The surgical method depends on the severity of the condition and the patient’s overall situation.

First: Traditional One-Stage Lengthening

Concept

The bone is lengthened in a single surgical procedure.

Procedure Steps

• Making a surgical incision over the metatarsal bone
• Performing a precise bone cut (osteotomy)
• Lengthening the bone to the desired position
• Fixing it with:
  • Metal plates and screws
  • Sometimes a bone graft is used to fill the gap

Advantages

• Completed in one operation
• Relatively shorter recovery period

Disadvantages

• Limited amount of achievable lengthening
• Risk of tension on the skin or nerves if excessive lengthening is attempted

Second: Gradual Lengthening (Distraction Osteogenesis)

Concept

The bone is gradually lengthened over time after surgery.

Procedure Steps

• Performing a small bone cut
• Installing an external or internal fixation device
• Gradually lengthening the bone, usually about 1 mm per day
• Allowing new bone to naturally form in the created gap

Advantages

• Allows greater and more precise lengthening
• Suitable for severe cases
• Provides good cosmetic and functional outcomes

Disadvantages

• Longer treatment period
• Requires continuous follow-up
• Temporary pain or stiffness may occur

Third: Internal Lengthening Devices

Concept

Using an expandable internal rod or device placed inside the bone.

Procedure Steps

• Inserting a specialized internal device into the bone
• Gradually controlling the lengthening process from inside the bone

Advantages

• No visible external device
• Better appearance during recovery
• Less embarrassment for the patient

Disadvantages

• Higher cost
• Not suitable for every case

Fourth: Acute Lengthening with Bone Graft

Concept

The bone is lengthened immediately during surgery with the help of a bone graft.

Procedure Steps

• Cutting the bone
• Opening the required space
• Placing a bone graft between the bone ends
• Stabilizing the area with plates or screws

Advantages

• No need for gradual lengthening
• Shorter recovery period compared to gradual techniques

Disadvantages

• Limited to smaller lengthening amounts
• Not suitable for severe shortening cases

Fifth: Fixation Only (For Mild Cases)

In very mild cases:

• The bone may simply be stabilized without major lengthening
• The goal is to improve appearance or reduce symptoms

Recovery Time After Brachymetatarsia Surgery

Recovery time varies depending on the type of surgery and the severity of the shortening, but it generally follows several stages.

First: Recovery According to the Surgical Technique

1. Traditional One-Stage Lengthening

• Initial bone healing: 6–8 weeks
• Gradual walking with a medical shoe: after 3–6 weeks
• Return to normal daily activities: within 2–3 months
• Return to full sports activities: within 3–4 months

2. Gradual Lengthening (Most Common)

• Lengthening phase: 4–8 weeks depending on severity
• Bone consolidation phase: 6–12 weeks
• Return to normal movement: within 3–6 months
• Severe cases may require: 6–8 months

3. Internal Lengthening Devices

• Initial healing: within 6–8 weeks
• Noticeable walking improvement: within 2–3 months
• Full recovery: around 3–4 months

Second: Factors Affecting Recovery Time

Recovery speed varies from person to person depending on several factors, including:

• Patient’s age (children heal faster than adults)
• Degree of bone shortening
• Commitment to the doctor’s instructions
• Presence of bone-related diseases or deficiencies in calcium or vitamin D
• Adherence to physical therapy after surgery

Tips for Managing and Preventing Symptoms of Brachymetatarsia

These tips are important for reducing symptoms and improving comfort while walking, especially in cases that do not require surgery or before deciding on treatment.

1. Choosing the Right Shoes

• Wear shoes with a wide front area to reduce pressure on the toes
• Avoid tight shoes or prolonged use of high heels
• Cushioned shoes help distribute pressure more evenly
• Athletic or orthopedic shoes are often the best choice for painful cases

2. Using Orthotic Insoles

• Help distribute body weight evenly
• Reduce pressure on the front of the foot
• May help prevent calluses and walking pain

3. Reducing Pressure on the Foot

• Avoid standing for long periods without rest
• Take breaks during walking or work
• Change standing positions frequently to reduce stress on the foot

4. Performing Simple Foot Exercises

• Stretching exercises for the foot muscles
• Daily toe movement exercises
• Calf and lower leg strengthening exercises

The goal is to improve balance and reduce discomfort.

5. Medical Follow-Up

It is recommended to see a doctor if:

• Pain becomes persistent
• Walking or wearing shoes becomes difficult
• The condition significantly affects appearance or self-confidence

6. Maintaining a Healthy Weight

Excess body weight increases pressure on the front of the foot. Maintaining a healthy weight may help reduce pain and improve mobility.

7. Psychological Adjustment and Coping

In many cases, Brachymetatarsia is more of a cosmetic issue than a serious disease.

Learning to adapt to the appearance of the foot and choosing suitable footwear can greatly improve confidence and comfort. In some cases, simple lifestyle adjustments are enough to reduce embarrassment and improve daily life.
