Foot DeformityFrom the moment we take our first steps, our feet play a crucial role in our daily activities. However, not all feet develop perfectly.

One common foot deformity is metatarsus adductus, which can affect people of all ages. In this article, we will delve into the causes, signs, and symptoms of this condition, as well as the available treatment options.

Whether for yourself or someone you know, understanding metatarsus adductus is essential in order to seek appropriate care and support.

Metatarsus Adductus

Metatarsus Adductus

Metatarsus adductus is a foot deformity characterized by a curved foot shape, usually affecting the metatarsal bones and leading to an inward curve of the middle part of the foot. This condition can be present at birth or develop later in life due to various factors.

Some babies are born with this condition due to the position of the baby in the womb, while others may develop it as a result of tight muscles or ligaments.

Foot Deformity

The curved foot shape caused by metatarsus adductus can range from mild to severe. Mild cases may only affect the front part of the foot, while severe cases can involve the entire foot.

The affected foot may appear to be curved inward, with the toes turning inward as well. It is important to note that metatarsus adductus does not cause any pain in most cases, but it can lead to issues with foot function and shoe fitting if left untreated.

Signs and Symptoms

Signs and Symptoms

Metatarsus adductus can be identified by certain signs and symptoms. In infants, the most common sign is a foot that bows inward, resembling a kidney shape.

This can usually be noticed by observing the way the baby’s feet lie against each other or when the child starts kicking and moving the legs. Older children may experience difficulties when walking, as their gait might be affected due to the deformity.

Curved Foot Shape

One of the most noticeable symptoms is the curved foot shape caused by metatarsus adductus. The foot may appear to have a C shape, with the heel pointing inward and the toes following suit.

This abnormal shape can cause challenges when selecting appropriate footwear, as standard shoes may not accommodate the curved foot properly. It is crucial to identify these signs and symptoms early on to seek professional advice and appropriate treatment.

Treatment Options:

Fortunately, metatarsus adductus can be effectively treated, especially when detected early. Treatment options may vary depending on the severity of the condition, but they typically include:


Stretching exercises: Gentle stretching exercises can be beneficial in helping to correct the curved foot shape. These exercises aim to relax tight muscles and ligaments, gradually allowing the foot to straighten over time.

2. Splinting or casting: In some cases, a healthcare provider may recommend using a splint or cast to hold the foot in a corrected position.

This can help reshape the foot and encourage proper alignment. 3.

Bracing: More severe cases may require the use of braces that help to maintain proper alignment of the foot. These braces are usually worn for a prescribed period of time, and regular check-ups are essential to monitor progress.

4. Physical therapy: Physical therapy sessions may be recommended to strengthen the muscles and improve foot function.

These sessions may include exercises, massages, and other therapeutic techniques. Conclusion:

Understanding metatarsus adductus is crucial in order to seek appropriate care and support.

By recognizing the signs and symptoms of this common foot deformity, early intervention and treatment can be implemented, promoting proper foot function and preventing potential complications in the future. If you suspect that you or your child may have metatarsus adductus, it is always best to consult with a healthcare professional for an accurate assessment and personalized treatment plan.

Remember, proper foot care leads to a solid foundation for a healthier and more active life.

Causes of Metatarsus Adductus

Causes of Metatarsus Adductus

Metatarsus adductus can have several causes, and understanding these causes is essential in addressing the condition effectively. While the exact cause of metatarsus adductus is not always clear, there are several factors that have been identified as potential contributors.

One of the primary causes of metatarsus adductus is fetal development in the womb. During pregnancy, the position of the baby can play a role in the development of this foot deformity.

If the baby’s feet are positioned in a way that places pressure on the foot, it can lead to the formation of metatarsus adductus. This is more likely to occur if the baby’s feet are pressed against the mother’s abdomen or if there is limited space in the womb.

Fetal Development and

Foot Deformity

The association between fetal development and metatarsus adductus has been widely recognized. The development of the baby’s foot begins in the early stages of pregnancy, and any disruption during this crucial period can result in a foot deformity.

The exact reason why the positioning of the baby’s feet in the womb can lead to metatarsus adductus is not completely understood, but it is believed to be due to the pressure on the developing foot. In addition to fetal positioning, other factors can also contribute to the development of metatarsus adductus.

Some studies suggest that genetics may play a role, as there is a higher prevalence of the condition in certain families. Environmental factors, such as tight or constrictive spaces in the womb, can also increase the likelihood of metatarsus adductus.

Maternal factors, including prenatal infections or substance abuse during pregnancy, may also contribute to the development of this foot deformity.

Diagnosis of Metatarsus Adductus

Diagnosis of Metatarsus Adductus

Diagnosing metatarsus adductus typically involves a comprehensive assessment by a healthcare professional. The initial diagnosis may be made based on a physical examination and observation of the foot shape.

However, additional tests and evaluations may be ordered to confirm the diagnosis and assess the severity of the condition. Physical Exam, Range of Motion

During a physical exam, the healthcare provider will carefully evaluate the foot shape and range of motion.

They will observe the alignment of the metatarsal bones, the position of the toes, and any restrictions in movement. A thorough examination of both feet will be conducted to compare the affected foot to the unaffected one.

The provider may gently manipulate and move the foot to assess the range of motion and the stiffness of the joints. They may also evaluate the muscle tone and strength in the foot and lower leg.

By performing these physical examinations, the healthcare provider can gather valuable information to help make an accurate diagnosis of metatarsus adductus. In some cases, additional tests may be ordered, such as X-rays or other imaging studies.

These tests can provide a more detailed view of the foot structure and help rule out any underlying conditions that may be contributing to the foot deformity. During the diagnosis process, it is important to maintain open communication with the healthcare provider and provide any relevant medical history or information that can assist in the accurate diagnosis of metatarsus adductus.


Through understanding the causes of metatarsus adductus and the diagnostic process, individuals can gain valuable knowledge about this foot deformity. By recognizing the potential factors that contribute to the development of the condition, healthcare providers can better tailor treatment plans to address the underlying causes.

The diagnosis of metatarsus adductus is a crucial step in the journey toward proper management and support. By collaborating with healthcare professionals and actively participating in the diagnostic process, individuals and their caregivers can ensure early intervention and improved outcomes for this common foot deformity.

Treatment Options

Treatment Options

When it comes to managing metatarsus adductus, various treatment options are available depending on the severity of the condition. The primary goal of treatment is to correct the foot deformity and improve foot function.

Treatment plans are typically tailored to each individual based on their age, the severity of the condition, and other contributing factors. Stretching Exercises, Casting, Surgery

For infants with mild to moderate metatarsus adductus, often referred to as flexible metatarsus adductus, non-surgical interventions are the first line of treatment.

One of the most commonly recommended treatments is stretching exercises. These exercises aim to lengthen and relax the tight muscles and ligaments in the foot, gradually guiding the foot into a more aligned position.

Parents or caregivers are usually taught how to perform these gentle stretches at home and are encouraged to incorporate them into the baby’s daily routine. In more severe cases or when stretching exercises alone do not yield the desired results, casting may be utilized.

Casting involves applying a series of plaster casts to the affected foot, gradually stretching and reshaping the foot into a corrected position. The casts are typically changed every one to two weeks, allowing for progressive correction.

This treatment method is most effective when started during infancy when the bones are still flexible and can respond well to external manipulation. In rare cases where conservative treatments are not sufficient or if metatarsus adductus is associated with other underlying conditions, surgical intervention may be considered.

Surgery is typically reserved for older children or adults and involves releasing tight structures and realigning the foot through various surgical techniques. It is important to note that surgery is generally considered an option of last resort and is only recommended when other non-surgical methods have been exhausted.

Prognosis and Complications

Prognosis for Infants

The prognosis for infants with metatarsus adductus is generally favorable. Many infants with mild to moderate flexible metatarsus adductus will naturally outgrow the condition as they grow and develop.

With appropriate stretching exercises or casting, the foot deformity can usually be corrected within the first few months of life. Regular monitoring by a healthcare provider is necessary to ensure proper progress and to adjust treatment as needed.

Flexible Metatarsus Adductus and Developmental Dysplasia of the Hip

It is important to recognize that metatarsus adductus, especially the more severe rigid form, can sometimes be associated with other conditions, such as developmental dysplasia of the hip (DDH). Developmental dysplasia of the hip refers to the abnormal development of the hip joint and can coexist with foot deformities like metatarsus adductus.

If a healthcare provider detects any signs or symptoms of DDH during the evaluation for metatarsus adductus, further investigations or referrals to a specialist may be warranted. Early detection of DDH is crucial for appropriate management and prevention of long-term complications.

While metatarsus adductus itself does not typically cause long-term issues or pain, if left untreated or neglected, it can lead to problems with foot function and shoe fitting. The foot deformity may persist into adulthood, potentially affecting walking patterns and causing discomfort.

That is why early intervention and proper management are essential to achieve the best outcomes for individuals with metatarsus adductus. Conclusion:

By exploring various treatment options and understanding the prognosis and potential complications associated with metatarsus adductus, individuals and their caregivers can make well-informed decisions regarding their healthcare journey.

Timely intervention through stretching exercises, casting, or, in rare cases, surgical procedures can help correct the foot deformity and improve foot function. With appropriate treatment and regular monitoring, the majority of infants with metatarsus adductus can expect favorable outcomes.

It is important to remain vigilant and seek professional advice for any concerns regarding foot development or associated conditions, ensuring a solid foundation for both physical and overall well-being. Metatarsus adductus is a common foot deformity that can affect individuals of all ages.

Understanding the causes, signs, and symptoms of this condition is crucial in seeking appropriate care and support. Through early diagnosis and intervention, treatment options such as stretching exercises, casting, or surgery can correct the foot deformity and improve foot function.

For infants, the prognosis is generally favorable, and with proper management, most cases can be resolved. It is important to be aware of potential associations with developmental dysplasia of the hip and to seek professional guidance in these situations.

The main takeaway is that early intervention leads to better outcomes. By recognizing and addressing metatarsus adductus promptly, individuals can ensure a solid foundation for a healthier and more active life.
