Sesamoiditis

What is sesamoiditis?

Sesamoiditis is an inflammation of the tissue surrounding one or both sesamoid bones under the ball of the foot, and it is often accompanied by swelling. The sesamoid bones are small bones located beneath the big toe (hallux), and they act as pivots for the tendons that flex the toe. These two bones are called the medial and lateral sesamoids. Inflammation most commonly affects the medial sesamoid bone, as this area receives the most impact during walking. It is also the primary attachment site for the flexor tendons that pull the big toe downward during the gait cycle. Sesamoiditis typically causes pain under the big toe joint, making walking painful and uncomfortable.

Sesamoiditis can cause significant discomfort when walking and may lead to an altered gait pattern. It occurs most commonly in young, active individuals who repeatedly apply pressure to this area of the foot.

What causes sesamoiditis?

Sesamoiditis refers to inflammation of the sesamoid bones. This inflammation can be caused by:

  • Repetitive stress or overuse from activities like running, dancing, or jumping
  • High-impact sports that involve pushing off the toes or forefoot pressure (e.g., basketball, ballet)
  • Wearing high heels or unsupportive footwear that puts excessive pressure on the ball of the foot
  • Reduced flexibility in the calf muscles or tight tendons, which increases stress on the forefoot
  • Foot biomechanical issues, such as high arches, flat feet, or excessive pronation
  • Sudden increase in physical activity or abrupt changes in training intensity

What are the symptoms of sesamoiditis?

Symptoms of sesamoiditis typically develop gradually and may include:

  • Pain under the ball of the foot, especially beneath the big toe
  • Tenderness when pressing on the sesamoid area
  • Swelling or bruising around the base of the big toe
  • Pain when bending or extending the big toe upward
  • Increased pain during walking, running, or when pushing off the toe
  • Difficulty wearing high heels or tight-fitting shoes due to pressure

Physiotherapy for sesamoiditis

Sesamoiditis can be effectively treated with a structured course of physiotherapy. The physiotherapists at acephysiosports.com are experienced in managing sesamoiditis, helping relieve pain and restoring normal function. Treatment may include:

  • Offloading padding or orthotic inserts to relieve pressure from the sesamoid bones
  • Taping techniques to support the big toe and reduce strain on the sesamoids
  • Manual therapy and joint mobilisation to improve flexibility and alignment of the big toe joint
  • Stretching exercises for the calf muscles and plantar fascia to reduce tension on the forefoot
  • Strengthening exercises for foot and ankle muscles to support proper biomechanics
  • Ice therapy to reduce inflammation and pain
  • Advice on activity modification, avoiding high-impact activity during recovery
  • Footwear recommendations, encouraging cushioned, supportive shoes with a low heel and wide toe box

At acephysiosports.com, our physiotherapists work closely with podiatrists who may also help manage the condition through customised orthotic insoles. Our team offers a comprehensive assessment, diagnosis and treatment plan to reduce pain and improve overall foot function.

Can sesamoiditis cause any long-term effects?

In the majority of cases, physiotherapy can effectively treat and rehabilitate sesamoiditis. If the problem becomes recurrent, orthotic insoles may be needed for long-term use, and physiotherapy can continue to help manage symptoms and improve function.
