Anatomy ● 2 sesamoid bones in the tendon of the flexor hallucis
near the 1st MTP joint
● Function to:● to increase the mechanical advantage of the flexor
hallucis longus and brevis and increase plantarflexion strength at the 1st MTP joint
● Disperse forces to the medial forefoot

Pathology
● Inflammation of the FHL tendon surrounding the sesamoid bones due to overuse and repetitive stress● Causes can be structural, such as pes cavus foot type,
and/or mechanical in nature
![Page 4: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/4.jpg)
Symptoms• Results in pain with weight bearing on the
forefoot
• Gradual onset of pain, worsened with increasing activity
• Aggravating factors include wearing high heels, jumping, running, stairs, and dancing
• Symptoms are alleviated with rest, ice, and non-weight bearing positions
![Page 5: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/5.jpg)
Considerations for Treatment● First ray position and mobility
● Rear foot alignment and mobility
● Forefoot alignment
● Dorsiflexion range of motion
● Demand placed on the foot in ADLs or sports
● Current stage of healing

Clinical Findings● Common findings for individuals with this pathology
include:
● Loss of ROM at 1st MTP joint
● Decreased plantarflexion and dorsiflexion strength of great toe● Painful static test
● Tenderness to palpation on of the 1st MT head on the plantar aspect
● Decreased weight bearing ability due to pain

Differential Diagnosis● Bursitis
● Chrondromalacia
● Tenosynovitis of the FHL
● Sesamoid fracture
● MRI and X-ray can assist in diagnosis process

Treatment● EdURep Model
● Educate the patient about the nature of their pathology● Unload the tissue and allow tissue healing to occur● Reload the tissue to increase ROM and strength as
needed● Progress treatment to mimic functional activities and meet
the demand the patient puts on the tissue in their daily lives
![Page 9: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/9.jpg)
Patient Education● Educate the patient about how they are placing excess
stress on the involved structures
● Teach patient how to move without stressing the sesamoids● Re-education for squatting, standing, walking
![Page 10: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/10.jpg)
Unloading Phase● Decrease the stress on the sesamoids by dispersing
forces over the forefoot● Use metatarsal pads or soft arch support● Taping the 1st MTP joint into slight plantarflexion● Lower heel height
● Avoid activities that reproduce symptoms● No jumping● No excessive 1st MTP dorsiflexion
![Page 11: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/11.jpg)
Reloading Phase● Once the patient is out of the inflammatory phase of
healing, progress to reloading the tissue to strengthen it and avoid re-injury
● Exercises focusing on FHL strength
● Stretching the 1st MTP joint to improve dorsiflexion
● Improving ankle ROM
![Page 12: Sesamoiditis: Cause and Treatment](https://reader033.fdocuments.us/reader033/viewer/2022042815/557ab013d8b42a6f378b4fa5/html5/thumbnails/12.jpg)
Progress● Once the patient has sufficient strength and range,
progress to adding weight bearing and functional exercises that mimic the activities the patient has to get back to
● Squatting, jumping, running
