Plantar Plate Injury

A plantar plate injury refers to an injury to one of the strong ligaments on the underside of the foot. The plantar plate is a tough fibrocartilagenous structure which attaches the proximal phalanx to the metatarsal head, going through the forefoot's joint capsule. The plantar plate plays an important role in keeping the toes in place, stopping them from drifting or over-extending.

Causes

The most common cause of a plantar plate injury is an overload of pressure on the metatarsophalangeal (MPJ) joint. This leads to strain which eventually causes attenuation and a tear in the plantar plate area. It is this tear which leads to the pain and instability which characterises the injury.

Plantar plate injuries usually occur gradually over time, although in some cases they can occur suddenly. Among the ways which they can develop are; bunions, which put pressure on the plantar plate and can push on the 2nd toe, dislocating it; biomechanical abnormalities, such as a long 2nd metatarsal, or elevated 1st metatarsal; and a cortisone injection, which sometimes has a side effect of thinning and weakening the plantar plate ligament.

Symptoms

The main symptoms of a plantar plate injury include; the toe changing position, which occurs gradually as the tear increases, usually to the side or upwards; pain, which is usually a sharp pain located in the ball of the foot, or a dull ache, which can make it feels like there is no cushion between the ground and the bone; swelling; and a chronic plantar plate injury, which can develop if a plantar plate injury is not treated adequately, and can lead to the deformity to become greater, arthritis, and a higher level of pain.

 

Treatment

A plantar plate injury is usually diagnosed firstly via a physical examination, which can involve the doctor moving or manipulating the affected toe. X-rays and additional imaging tests such as MRI scans can also be used to confirm a plantar plate injury.

Among the non-surgical treatments which can be used to treat plantar plate injuries are; rest; ice treatment; and the strapping of the toe and the use of accommodative padding to ease the effect of the weight which is placed on the MPJ joint. Boots can be worn in order to take the pressure off the ball of the foot, along with taping which holds the toe in a position that allows the ligament to heel better.

Orthotics - such as inserts and supports which are placed under the ball of the foot - can be prescribed. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) such as ibuprofen can be used to relieve pain.

Often surgical treatments will be needed in orders to correct the problem. Surgical procedures which can be used include; the hat-trick procedure, which realigns the metatarsal bone; and complete plantar plate repair system, which uses a suture passing approach and anatomic repair to realign the joint.

As with all foot surgery, it is common for swelling to persist for some months after surgery and is completely normal. This swelling will eventually completely subside with time and can take up to 12 months but often goes well before this.

Patient stories

Mr Ajis is a great surgeon, he listens to any concern you may have and explains what is going to happen also gives great care... He suggested a fairly new procedure that wasn't available on the NHS but he pushed me through and he and his team have worked wonders, I am now healing very well and pain-free in my ankle after 6 years!

Written by a patient at BMI Goring Hall Hospital

Mr Ajis was very informative and reassuring about my surgery. He was professional at all times and allowed time for me to have all my questions answered without feeling rushed.

Written by a patient at BMI Goring Hall Hospital

I saw Mr Ajis after sustaining a fracture of my 5th metatarsal which had not healed after a year. The pain was unbearable. He saw me promptly and took the time to explain my condition with the help of x-ray images with assurances that he could fix the problem. I was advised by other clinicians to be patient and wait for the fracture to heal on its own. Mr Ajis said that healing would be highly unlikely without intervention. After numerous emails and 'phone calls to him he constantly...

...spent the time reassuring me and patiently going over the intended procedure. To date after seeking advice and guidance from Mr Ajis, his secretary and the Physio Team and the insertion of a plate my fracture has united I walk well, without pain and I have joined a walking group. In summary, he is the best foot consultant the South of England can provide. In fact, I travelled from both the IoM and the IW to West Sussex to see him.
