We have all heard about Cam Newton’s foot injury with speculation he is dealing with a Lisfranc injury. If this is true, the most likely outcome will be season ending surgery.
A Lisfranc injury can be classified into three different categories including sprains, fractures, and dislocations. The most severe form of the injury is a dislocation of the metatarsal bones from the tarsal bones especially at the 2nd tarsometatarsal joint. This injury usually occurs as a result of combined external rotation and compressive force on the foot. In football, the prime example is having an opponent step on the foot of another opponent while attempting to change direction. This is typically more common in football, but can occur in soccer and basketball as well.
Often time Lisfranc injuries are categorized as a simple sprain of the foot especially if there are no radiographic changes present. Conservative treatment focuses on decreasing pain and allowing the tissue and structures time to heal. Time is usually the best prognostic factor for determining success with conservative treatment. Often athletes, especially professional athletes, face a tough decision because they want to get back as soon as possible. If you return too quickly and the foot is unable to tolerate the high levels of stress, re-injury is inevitable.
Rehab focuses on restoring the intrinsic foot muscles to help alleviate some of the strain on the Lisfranc ligament. Check out @movementologist for foot intrinsic exercises. Once some weight bearing can be initiated without severe pain, any type of balance/proprioception training is warranted. Then progressing to gentle plyometrics in double limb support before moving onto single leg plyometrics.
The final step in the rehabilitation process is the return to running in a straight line with progression to cutting and changing direction to restore full tolerance to all dynamic, weight bearing activities. The one variable you cannot account for as a physical therapist is an opponent stepping on the athlete’s foot when attempting to change direction. Sometimes no matter how much preparation and training an athlete puts in to minimize the chance of injury, a “true” contact can not be prevented.
