METACARPO-PHALANGEAL JOINTS

The radial collateral ligament of the index finger is most vulnerable, although with a suitable force any ligament can be injured. The tension of the ligament is tested with the MP joint flexed (if extended, even a normal ligament is very lax!).

In children, the injury may be accompanied by a Salter–Harris III fracture at the base of the proximal phalanx.

A large bone fragment, if displaced, can be reattached from a palmar approach, using a tension band suture or small screw. Smaller fragments are treated by splintage with the MP joints flexed.

掌指骨关节

食指的桡侧副韧带是最脆弱的，但只要用力适当，任何韧带都可能受伤。韧带的张力是在MP关节弯曲的情况下测试的（如果伸展，即使是正常的韧带也会非常松弛！）。

对于儿童，损伤可能伴有近节指骨底部的Salter-HarrisⅢ型骨折。

大的骨碎片，如果移位，可以从手掌入路，使用张力带缝线或小螺丝钉重新连接。较小的碎片用夹板固定，MP关节弯曲。
