The human body features unique bones called sesamoids, which are generally small in size and dispersed across several regions such as hands, knees, and feet. Interestingly, the feet comprise two such bones that are situated under the joint of the big toe and concealed within the tendons that lead to it. The crucial function of these bones is to aid foot mechanics by regulating weight distribution and shock absorption, especially during physically demanding activities like running or jumping.
Although diminutive in size, sesamoid bones are inclined to get injured, particularly in people who engage in activities that exert excessive pressure on their feet. A prevalent sort of injury related to sesamoid bones is a fracture of these bones.
In case of a sesamoid bone fracture, either one or both of the small bones found in the foot get damaged or cracked due to several reasons such as direct foot trauma, repeated stress, overuse or sudden motion of twisting and turning.
There are two major types of fractures associated with sesamoid bones: acute fractures and stress fractures.
- Acute Fractures - When the sesamoid bone receives a sudden and intense impact, acute fractures can occur. The incident commonly results in instant and excruciating agony, as well as inflammation and discoloration.
- Stress Fractures - When the sesamoid bone is exposed to frequent pressure over an extended period, it can lead to stress fractures. This is often caused by participating in high-impact activities like running or jumping, or even wearing ill-fitting shoes like high heels or tight footwear. Symptoms of stress fractures could reveal themselves as a persistent ache or discomfort that tends to worsen as you become more active.
There are several common signs and symptoms, which encompass:
- Discomfort: One of the frequently encountered indications of a sesamoid bone fracture is discomfort in the forefront of the foot or underneath the joint of the hallux. The level of pain may vary from slight to intense. Discomfort may intensify during weight-bearing exercises or while walking barefoot.
- Edema: Edema in the impacted region is also a prevalent indication of a fracture in the sesamoid bone. The region surrounding the damaged sesamoid bone may exhibit erythema or contusions and may elicit tenderness or warmth upon palpation.
- Inability to bear weight: If the fracture of the sesamoid bone is pronounced, the ability to bear weight on the impacted foot may be compromised. This may result in challenges when it comes to ambulation or engaging in physical pursuits.
- Restricted mobility: Fractures of the sesamoid bones can also impede the mobility of the impacted digit or appendage. It may impede the ability to flex or bend the toe or foot, resulting in sensations of discomfort or pain while attempting to perform these actions.
- Sensory disturbances: The occurrence of sensory disturbances such as numbness or tingling may indicate a sesamoid bone fracture in certain cases.
There are several reasons why fractures in the sesamoid bone may occur, such as physical injury, recurring strain, and anomalous foot anatomy.
- Trauma: Sesamoid bone fractures are frequently attributed to trauma, especially in instances of sudden fractures. Such trauma could be induced by a forceful impact to the foot, like a tumble or a massive object landing on it.
- Repetitive Stress: Sesamoid bone fractures could also be a repercussion of repetitive stress, especially stress fractures. Pursuits that necessitate frequent pressure, for instance, running or jumping, may prompt small cracks in the sesamoid bone, which may aggravate over time, ultimately resulting in a complete fracture.
- Unusual Foot Structure: Individuals with unusual foot structure, such as uncommonly high arches or completely flat feet, may be at a higher risk of experiencing sesamoid bone fractures. The reason for this increased risk is due to the uneven stress that these foot structures place on the sesamoid bones, which in turn can make these bones more vulnerable to potential harm.
Various risk factors can increase the probability of developing sesamoid bone fractures. These include:
- High-Impact Activities: Activities like running, jumping, or dancing, can increase the risk of developing sesamoid bone fractures, particularly stress fractures.
- Abnormal Foot Structure: As mentioned earlier, abnormal foot structures, such as flat feet or high arches, can also increase the risk of sesamoid bone fractures.
- Tight Footwear: Wearing tight or ill-fitting footwear can increase the pressure on the sesamoid bones, making them more susceptible to injury.
- Overuse: Overuse of the foot, such as engaging in long-distance running or dancing for extended periods, can also increase the risk of developing sesamoid bone fractures.
- Previous Injuries: Previous injuries to the foot or ankle, such as sprains or fractures, can weaken the bones and make them more susceptible to further injury, including sesamoid bone fractures.
While you cannot completely prevent sesamoid bone fractures, there are various things that you can do to reduce your risk of developing these injuries. Some prevention tips include:
- Wearing Appropriate Footwear: Wearing shoes that fit properly and provide adequate support can help to reduce the risk of sesamoid bone fractures. Also avoid wearing high heels or tight shoes for extended periods.
- Stretching and Strengthening Exercises: Stretching and strengthening exercises can help to improve the flexibility and strength of the foot muscles, reducing the risk of injury.
- Gradual Increases in Activity: Gradually increasing the intensity and duration of high-impact activities can help to reduce the risk of developing stress fractures.
- Proper Technique: Using proper technique when engaging in high-impact activities can help to reduce the impact on the sesamoid bones, reducing the risk of injury.
Diagnosing sesamoid bone fractures typically involves a physical examination and imaging tests. During a physical test, a physician will look for signs of swelling, tenderness, and bruising around the affected area. They may also check for any limitations in range of motion or difficulty bearing weight on the affected foot. Imaging tests may also be used to confirm the diagnosis and determine the type and severity of the fracture.
Sesamoid bone fractures can be classified into several stages, based on the severity of the injury. These stages include:
- Stage 1: Stage 1 fractures are considered mild and typically involve only a small crack or stress fracture in the sesamoid bone. Treatment for Stage 1 fractures may include rest, ice, and immobilisation.
- Stage 2: Stage 2 fractures involve a larger crack or stress fracture in the sesamoid bone. Treatment for Stage 2 fractures may include immobilisation, as well as physical therapy to help improve range of motion and strengthen the foot muscles.
- Stage 3: Stage 3 fractures involve a complete fracture of the sesamoid bone. Treatment for Stage 3 fractures may include immobilisation, as well as surgery in some cases.
Sesamoid treatment options may include:
- Rest and Immobilization: Resting the foot and immobilising the area with a brace or cast can help to reduce pain and swelling and promote healing.
- Ice and Elevation: Applying ice to the affected area and elevating the foot can also help to reduce swelling and promote healing.
- Pain Medications: Over-the-counter pain medications like acetaminophen or ibuprofen, may be used to help manage pain and reduce inflammation.
- Physical Therapy: Physical therapy can help to improve range of motion and strengthen the foot muscles, reducing the risk of further injury.
- Surgery: In more severe cases, surgery may be necessary to remove the damaged sesamoid bone or repair a complete fracture.
Recovering from a sesamoid bone fracture can take several weeks to several months, depending on the severity of the injury and the chosen treatment plan. During the recovery period, it's important to follow the recommended treatment plan and avoid putting too much weight or stress on the affected foot.
Once the foot has healed, it's important to take steps to prevent further injury. This may include:
- Wearing appropriate footwear
- Engaging in regular stretching and strengthening exercises
- Avoiding high-impact activities that may put too much stress on the sesamoid bones
In some cases, individuals may also benefit from custom orthotics or shoe inserts to provide additional support and reduce the risk of future injury.
