Turf toe is an extreme traumatic dorsiflexion (hyperextension) injury of the toe results in plantar plate injury from sprain to complete tear of the plantar plate capsuloligamentous complex and allows unrestricted range of motion of the first metatarsophalangeal (MTP) joint. It is common in professional athletes, especially on artificial surfaces and is not particular to a specific sport, but is commonly seen in football, soccer, and baseball players.

草皮趾是腳趾的極端創(chuàng)傷性背屈（過度背伸）損傷，導(dǎo)致跖板損傷，表現(xiàn)為第一跖趾關(guān)節(jié)（MTP）的關(guān)節(jié)囊韌帶復(fù)合體扭傷或完全撕裂，關(guān)節(jié)不受限制的運(yùn)動(dòng)。 這在職業(yè)運(yùn)動(dòng)員中是常見的，特別是在人造草皮上，并不是一定是特定的運(yùn)動(dòng)，但是通常發(fā)生在橄欖球，足球和棒球運(yùn)動(dòng)員。

Grading

Turf toe injuries are graded from 1-3 in severity:

• grade 1 - stretch or minor tearing of the 1st MTP capsuloligamentous structures

• grade 2 - partial tearing of the capsuloligamentous structures with intact articular surface

• grade 3 - complete disruption of the capsuloligamentous structures with impaction deformity of the MTP, articular cartilage damage, trabecular edema, sesamoidal fracture, or diastasis of sesamoidal fragments

分級(jí)可分為三度：

• Ⅰ度損傷是指第一跖趾關(guān)節(jié)囊韌帶復(fù)合體結(jié)構(gòu)的牽拉或輕度撕裂,一般可以忍受疼痛。

• Ⅱ度損傷是第一跖趾關(guān)節(jié)足底關(guān)節(jié)囊韌帶復(fù)合體的部分?jǐn)嗔?大概需要2周才能恢復(fù)。

• Ⅲ度損傷是第一跖趾關(guān)節(jié)足底關(guān)節(jié)囊韌帶復(fù)合體的完全斷裂,關(guān)節(jié)軟骨損傷，骨小梁水腫，籽骨骨折等，需要10-16周的時(shí)間恢復(fù),部分需要手術(shù)治療
