A plantar plate injury, is one of the most common causes of pain experienced in the ball of the foot.
The plantar plate is a fibrous thickening of the joint capsule under the metatarsal heads.
Injuries range from partial tear to complete rupture.
Typically caused by overuse, when high loads are placed on the forefoot, it places more load through the plantar plates. Increased load through the forefoot can result from poor biomechanics or incorrect footwear (e.g. high heels).
Pain is felt under the ball of the foot (forefoot) in a clearly defined area under the metatarsal head. Pain is noted when standing or walking around and decreases with offloading or sitting. Some swelling may be noticed under or on top of the area. In some cases this swelling can impinge on nerves causing a numb sensation in the forefoot. You may even notice your toe may have shifted position.
Your podiatrist will diagnose a Plantar Plate Injury by checking your medical history and performing a Biomechanical Assessment during which your movement will be studied. Radiology may be requested to assist with diagnosis.
Treatment
This may involve initial activity modification, icing, anti-inflammatory medications, taping and the correction of biomechanical abnormalities using orthoses. Your podiatrist will also be able to assess and determine why you developed a plantar plate injury and address this during your recovery to prevent a re-occurrence when you return to full participation.
