Facts about Metatarsophalangeal joint
- 08
Approximately 65 to 75 percent of people with hallux valgus experience pain during activities involving metatarsophalangeal joint extension due to altered biomechanics and cartilage stress.
- 07
Lateral deviation of the metatarsophalangeal joint exceeding 15 degrees is clinically diagnosed as hallux valgus, commonly known as a bunion, affecting approximately 10 percent of the general population.
- 06
Turf toe, an injury to the first metatarsophalangeal joint commonly sustained by athletes on artificial surfaces, results from hyperextension and typically requires 3 to 6 weeks of immobilization for recovery.
- 05
Sesamoid bones embedded within the tendons beneath the first metatarsophalangeal joint act as fulcrums that increase mechanical leverage by approximately 20 to 30 percent during push-off activities.
- 04
Dorsiflexion and plantarflexion at the metatarsophalangeal joint typically occur through a range of 65 to 90 degrees during normal walking gait cycles.
- 03
During the pushoff phase of gait, peak plantar pressures at the metatarsophalangeal joint can exceed 200 kilopascals in healthy individuals without proper footwear support.
- 02
Hallux limitus, a condition restricting motion in the metatarsophalangeal joint of the big toe, affects approximately 2 to 10 percent of the population and commonly develops from repetitive stress in athletes.
- 01
The first metatarsophalangeal joint bears approximately 40 percent of body weight during walking and up to 2.5 times body weight during running.
