Turf toe is specifically a sprain of the largest joint of your big toe, medically known as the metatarsophalangeal (MTP) joint. It occurs when this joint is forcibly bent upwards beyond its normal range of motion.
Understanding Turf Toe
This common athletic injury is essentially a ligament sprain in the main joint of the big toe. Your big toe, unlike other toes, has two joints. The metatarsophalangeal (MTP) joint is the larger of these two and connects the long bone in your foot (metatarsal) to the first bone of your big toe (phalanx). When this joint experiences hyperextension, the ligaments supporting it can stretch or tear, leading to a turf toe injury.
How Does Turf Toe Occur?
Turf toe typically results from an injury where the big toe is forcibly bent upwards (hyperextended). This often happens when the foot is planted flat on the ground and the heel lifts, causing the toes to extend sharply.
Common scenarios that can lead to turf toe include:
- Pushing off into a sprint: Athletes often sustain this injury when accelerating quickly, especially on artificial turf surfaces (hence the name).
- Landing awkwardly: Falling or landing with the toe jammed into the ground.
- Direct impact: Something heavy falling on the back of the heel, forcing the toe upwards.
