So, let’s embark on this journey together and unlock the mysteries of sesamoiditis.
Anatomy of the Sesamoid Bones
The sesamoid bones are small, rounded bones found in various parts of the body, with the most well-known examples located beneath the big toe joint. Typically, two sesamoid bones in the foot, the medial (tibial) and lateral (fibular) sesamoids are embedded within the flexor hallucis brevis muscle tendons. These tiny, pea-sized bones may be small, but they play a significant role in the overall function and mechanics of the foot.
The primary function of the sesamoid bones in the foot is to act as a pulley system, improving the mechanical efficiency of the tendons they are associated with. The sesamoids beneath the big toe assist in the movement and leverage of the flexor hallucis brevis muscle, a critical component of our ability to push off the ground when walking or running. Additionally, the sesamoid bones help distribute weight and pressure across the ball of the foot, providing a protective cushion for the joint and soft tissues during weight-bearing activities.
How They Aid Gait
As we walk, run, or engage in other physical activities, the sesamoid bones glide within their respective tendons, allowing for a smooth, coordinated motion of the big toe joint. This gliding action helps maintain optimal joint alignment, enabling efficient force transfer from the muscles to the bones and propelling us forward with each step.
During weight-bearing activities, the sesamoid bones absorb and distribute the forces exerted on the ball of the foot, reducing the stress on the surrounding tissues and structures. This protective function is essential during high-impact exercises or activities that place significant pressure on the forefoot, such as jumping, dancing, or sprinting.
Despite their small size, the sesamoid bones profoundly impact our mobility and overall foot health. By understanding their anatomy and function, we can better appreciate the complex biomechanics of the foot and the importance of maintaining the health and integrity of these tiny yet powerful bones.
Causes and Risk Factors of Sesamoiditis
Common causes of sesamoiditis
One of the primary causes of sesamoiditis is repetitive stress and overuse of the forefoot. When the sesamoid bones and surrounding structures are subjected to excessive pressure or friction over an extended period, inflammation and irritation can occur. This is particularly common in activities that involve frequent bending of the big toe or placing increased weight on the ball of the foot, such as running, dancing, or playing sports.
Although less common, sesamoiditis can also result from acute trauma to the forefoot. This can occur when the foot is suddenly twisted or impacted, causing direct injury to the sesamoid bones or surrounding soft tissues. In some cases, acute trauma can lead to a fracture of the sesamoid bones, which may also present symptoms similar to sesamoiditis.
Identifying risk factors
Athletes and individuals who engage in high-impact sports or activities are at a higher risk of developing sesamoiditis. This includes runners, dancers (particularly ballet dancers), basketball players, and soccer players whose feet are subjected to repeated stress and forceful movements.
Individuals with certain foot structures or biomechanics may be more susceptible to sesamoiditis. For example, those with high arches, flat feet, or a tendency to overpronate may place uneven pressure on the sesamoid bones, increasing the risk of inflammation and irritation.
Occupations that require extended periods of standing, walking, or repetitive movements involving the forefoot can contribute to the development of sesamoiditis. Workers in healthcare, retail, construction, and other physically demanding professions should be aware of their increased risk and take the necessary precautions to maintain their foot health.
Sesamoiditis and other foot conditions
Sesamoiditis can be associated with other foot conditions that affect the big toe joint or the surrounding structures. For example, hallux valgus (bunions) or hallux rigidus (stiff big toe joint or arthritis) can alter the foot biomechanics, increasing stress on the sesamoid bones. Additionally, conditions such as metatarsalgia, turf toe, plantar plate tear or stress fractures in the surrounding bones can exacerbate or mimic the symptoms of sesamoiditis, making accurate diagnosis and treatment more challenging.
Symptoms and Diagnosis
Typical sesamoiditis symptoms
One of the most common symptoms of sesamoiditis is localized pain beneath the big toe joint. The pain may be a dull ache or a sharp, stabbing sensation, often worsening with movement or pressure on the ball of the foot. This discomfort can make it difficult to walk, run, or engage in other weight-bearing activities without experiencing significant pain.
Inflammation of the sesamoid bones and surrounding tissues can lead to visible swelling and redness around the affected area. The inflammation may be accompanied by a sensation of warmth or tenderness when touched, signalling the presence of an underlying issue.
As sesamoiditis progresses, the ability to bend or flex the big toe may become limited due to pain and swelling. This restriction in movement can have a significant impact on daily activities, as well as athletic performance, making it essential to address the issue promptly.
Diagnostic procedures
A thorough physical examination by a podiatrist or another healthcare professional is the first step in diagnosing sesamoiditis. The examination typically involves assessing the range of motion of the big toe, checking for tenderness and swelling around the sesamoid bones, and applying pressure to the area to gauge the patient’s pain response.
Imaging techniques may be employed to confirm the diagnosis of sesamoiditis and rule out other conditions, such as fractures or bone abnormalities. X-rays can reveal changes in the bone structure. At the same time, MRI and ultrasound can provide more detailed information about the soft tissues, tendons, and ligaments surrounding the sesamoid bones.
Diagnosing sesamoiditis can be complex, as the symptoms often mimic other foot conditions, such as stress fractures, tendonitis, or bursitis. Additionally, the subtle nature of sesamoiditis symptoms can lead to misdiagnosis or delayed treatment, prolonging the recovery process. A comprehensive diagnostic approach, including a detailed patient history, physical examination, and appropriate imaging techniques, is essential to ensure an accurate diagnosis and the implementation of an effective treatment plan.
Treatment Options for Sesamoiditis
Conservative treatments
The initial approach to treating sesamoiditis typically involves conservative measures, such as the RICE protocol (rest, ice, compression, and elevation). By reducing physical activity, applying ice to the affected area, compressing the foot with a supportive wrap, and elevating the foot above heart level, patients can minimize inflammation and alleviate pain during the early stages of sesamoiditis.
Altering footwear and using orthotic inserts can provide relief for individuals with sesamoiditis. Custom orthotics or cushioned insoles can help redistribute pressure away from the sesamoid bones, while shoes with a wide toe box, adequate arch support, rocker-bottom and proper cushioning can alleviate stress on the affected area.
Non-prescription pain relievers, such as naproxen or ibuprofen, can help manage pain and reduce inflammation associated with sesamoiditis. However, these medications should be used as directed and under the supervision of a healthcare professional to ensure safety and effectiveness. Alternatively, those who get stomach irritated from anti-inflammatories can investigate using the gel alternative. I often recommend ibuprofen or diclofenac gel.
Physiotherapy and rehabilitation
Physiotherapy can play a crucial role in the recovery process for individuals with sesamoiditis. Strengthening exercises targeting the muscles and tendons surrounding the sesamoid bones can help alleviate stress on the affected area and improve overall foot function and stability.
Incorporating stretching and flexibility exercises into a rehabilitation program can enhance the range of motion of the big toe joint and reduce the risk of further injury. Techniques such as self-massage, foam rolling, and targeted stretches can help improve tissue flexibility and relieve tension in the affected area.
Gait training, or retraining, is a valuable tool in managing sesamoiditis. A podiatrist or physiotherapist can help patients improve their walking or running mechanics. This ensures a more efficient and less stressful force distribution on the sesamoid bones during weight-bearing activities.
Advanced treatment options
In cases where conservative treatments fail to provide relief, corticosteroid injections are next in line. These injections can help reduce inflammation and provide temporary pain relief. However, they should be used sparingly due to the potential side effects and risks associated with repeated injections (it can reduce the integrity of tissues it comes into contact with).
Extracorporeal shockwave therapy (ESWT) is a non-invasive treatment option involving delivering high-energy sound waves to the affected area. This therapy can help stimulate healing by promoting blood flow and tissue repair, potentially relieving those with persistent sesamoiditis.
Surgery is typically reserved for severe or chronic cases of sesamoiditis that do not respond to conservative treatments or other advanced options. Surgical procedures may involve the removal of the affected sesamoid bone (sesamoidectomy) or releasing tight tendons and soft tissues surrounding the joint (tenolysis). Sometimes, the sesamoid bones may be displaced, and surgical reduction is needed. This often occurs when there is a plantar plate tear. The decision to undergo surgery should be made in close consultation with a qualified podiatric surgeon. Focusing on weighing up the potential risks and benefits.
Prevention Strategies
Proper footwear selection
Choosing the correct footwear is one of the most critical factors in preventing sesamoiditis. Shoes should provide adequate support, cushioning, and stability while accommodating the natural shape and movement of the foot. A wide toe box, rocker-bottom, sufficient arch support, and appropriate shock absorption can significantly reduce the risk of developing sesamoiditis. Custom orthotics or cushioned insoles can help address specific foot biomechanics or pressure points.
Gradual increases in activity and training intensity
Gradually increasing the intensity and duration of physical activities can help minimize the risk of sesamoiditis caused by overuse. Adopting a progressive training program that allows the body to adapt to new stressors can prevent excessive strain on the sesamoid bones and surrounding structures. Listening to your body and allowing adequate rest and recovery periods are essential to avoid overloading the feet.
Regular stretching and strengthening exercises
Incorporating regular stretching and strengthening exercises into your routine can help maintain the health and function of the foot. Targeted exercises for the muscles, tendons, and ligaments surrounding the sesamoid bones can improve foot stability, flexibility, and biomechanics. Maintaining a strong and flexible foundation can significantly reduce the risk of sesamoiditis and other foot conditions.
Paying attention to early warning signs
Recognizing and addressing early warning signs of sesamoiditis can be instrumental in preventing the condition from progressing to more severe stages. If you experience pain, swelling, or restricted movement in the big toe joint, it is crucial to seek prompt medical attention and take appropriate measures to alleviate symptoms. Ignoring or “pushing through” pain can lead to further injury, prolong recovery, and potentially cause long-term damage.
