In addition to the knee, you can also find sesamoid bones in the hand. Most people have five hand sesamoids. The most common hand sesamoids are two small bones that start at the base of the thumb distal aspect of the first metacarpal.
Injury to these bones can be difficult to diagnose. Therefore, research articles and case studies rarely feature sesamoids of the hand 3. Patients with upper extremity injuries or surgery often need multiple therapy sessions to make a full return to function without pain.
Start by addressing the isolated movement of the hand and wrist. Once the patient masters isolated movements, you can then move on to integrating functional tasks to restore normal use. These should focus on isometric contractions and muscle control for the first few sessions. Then, the patient can move on to concentric and eccentric exercise , at a submaximal level.
The Simulator II and PrimusRS systems offer the capability of working small isolated hand movements in the three primary phases of contractions: isometric, concentric, and eccentric. Transitioning from isolated to functional exercises ensures that the patient is capable of doing more complicated tasks, pain free. When strength and endurance improve, the return to function assessment consists of multi-dimensional movements through multiple planes. Lastly, and certainly not least, are the most common sesamoids of the foot.
Located in the big toe, these are the tibial sesamoid on the medial plane and fibular sesamoid on the lateral plane. These two small bones act as a typical tendon support, but they also bear weight and stress. They help transfer force while standing, walking, running, dancing, or jumping.
Though they are incredibly important to function, these their injuries are difficult to diagnose accurately 4. As a result, some patients unfortunately receive ineffective recommendations and treatments. When a patient has pain or injury in the big toe, you can bet that it probably involves one of the two sesamoids. Tightness in the ankle and calf can also contribute to stress around the foot sesamoids.
Therapists should address this early on in the intervention process. If the sesamoid bone fractures, the patient may need surgery to remove the bone fragments. The surgeon will attempt to leave as much of the sesamoid intact in order to prevent future stress and the formation of bunions.
If there is no fracture, or following sesamoid surgery, rehab therapists have many options for treating an injured foot sesamoid. Rehab should include pain management, taping, bracing, calf stretching, and recommending orthotic shoes firm sole. And, of course strengthening of the structures surrounding the injury and addressing any deficits within the kinetic chain are always recommended. From here, the goal is to help heal the damaged bones and surrounding tissues, while treating any contributing factors to help prevent sesamoiditis from coming back in the future.
We often use a combination of full-length custom orthotics with supportive footwear to achieve this. The orthotic is designed in a way that deflects pressure away from the big toe joint, instead redistributing the pressure over the lesser toes at the ball of the foot. Orthotics can also help address contributing factors like flat feet pes planus , high arched feet pes cavus , bunions or those with reduced plantar fat padding.
In the case of persistent severe sesamoiditis or stress fractures of the sesamoids, the use of a short leg pneumatic walker with rocker sole walking cast for 2 to 6 weeks may be required.
Failing this, an injection of steroids or surgery may be considered. In severe cases or following a true fracture of the sesamoids, surgery may be required to remove the damaged or fragmented sesamoid bone. In some cases, due to reduced blood supply, there may be delayed or absent healing and a surgical review is warranted.
Most individuals will have an immediate improvement in symptoms once the pressure is removed from the sesamoids using orthotics and deflective padding. If there are no complications, complete resolution can be achieved within months. Sesamoiditis normally heals within a few days for mild cases with the help of resting, icing and anti-inflammatory medication. However, the healing period will differ case-by-case depending on the severity.
If sesamoiditis is triggered and untreated for a prolonged period, permanent damage can be caused in the sesamoid bones in the feet. However, if treated in the early stages, it can be managed. Often, the best treatment for sesamoiditis is resting and avoiding or changing the routines that trigger it dancing, running, etc. Sesamoiditis cannot be definitively cured, as there is always a risk of re-triggering it.
It can be managed and prevented, though. This may require a lifestyle change, like regular resting and icing after strenuous activities, or avoiding triggering activities all-together.
It is important to start treatment in the early stages to avoid permanent damage and to return to your normal lifestyle as soon as possible. What are orthotics used for? Custom foot orthotics are shoe inserts designed to support the natural shape of the foot, align the ankle and improve posture and foot function in general. At My FootDr our podiatrists prescribe orthotics to treat a range of foot, ankle, leg and lower back conditions.

They can give you support, stability and comfort — or put you at risk of injury or pain from blisters, corns, ankle sprains and more. Note: Swelling and bruising may or may not be present. Treatment options for a sesamoid injury will vary based on the type of Sesamoid injury that a podiatrist diagnoses on an individual basis.
With a diagnosis of sesamoiditis, treatment is usually non-operative. However, if conservative measures fail surgery may be recommended to remove the sesamoid bone in the foot. Occasionally, surgical fixation of a fractured sesamoid is needed. Appointments Patient Login. Doctors Eric Pack, D. Ginger Sellars, D. Sesamoid Injuries.
