P is for Plantar Plate Tear

March 25, 2020

A plantar plate tear is a strain or tear of the thickened joint capsule plantar to the lessor metatarsophalangeal joints in the ball of the foot. It is a common cause of pain in the ball of the foot.

Plantar Plate Tear

A plantar plate tear, also known as a plantar plate injury or plantar plate dysfunction, refers to a damage or rupture of the plantar plate, which is a strong ligament-like structure located on the underside of the foot. The plantar plate is responsible for stabilizing and supporting the metatarsophalangeal joints (the joints connecting the long bones of the foot to the toes).

Plantar plate tears commonly occur at the base of the second toe but can also affect other toes. They are often caused by repetitive stress or trauma to the foot, such as excessive pressure, overuse, or a sudden forceful impact. Factors such as overpronation (excessive inward rolling of the foot), tight calf muscles, and structural abnormalities in the foot can contribute to the development of plantar plate tears.

The symptoms of a plantar plate tear may include:

  1. Pain: Typically felt under the ball of the foot, especially at the base of the affected toe. The pain may be sharp, localized, or throbbing.
  2. Swelling: Inflammation and swelling may occur at the site of the tear.
  3. Instability: The affected toe may feel unstable or “floppy” due to the compromised integrity of the plantar plate.
  4. Difficulty walking: Walking or bearing weight on the affected foot may be uncomfortable or painful.

If you suspect a plantar plate tear, it is important to seek medical attention for a proper diagnosis. A healthcare professional, such as a podiatrist, will typically evaluate the foot through a physical examination, medical history review, and possibly imaging studies like X-rays or an MRI to assess the extent of the injury.

Treatment options for a plantar plate tear may include:

  1. Rest and activity modification: Avoiding activities that exacerbate symptoms and reducing pressure on the affected foot.
  2. Immobilization: Wearing a walking boot, a stiff-soled shoe, or using crutches to promote healing and protect the foot from further damage.
  3. Orthotic devices: Custom orthotic inserts or padding may be prescribed to provide support and reduce stress on the plantar plate.
  4. Physical therapy: Specific exercises and stretches can help improve strength, flexibility, and stability of the foot.
  5. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be recommended to alleviate pain and reduce inflammation.

In cases where conservative treatments do not provide sufficient relief or if the tear is severe, surgical intervention may be considered to repair or reconstruct the plantar plate.
