Indians right-hander Alex White will miss 8-12 weeks because of a middle-finger sprain, Tribe head trainer Lonnie Soloff said Sunday. This type of injury is commonly called a "jammed finger." It is a sprain of the volar plate (floor) of the proximal interphalangeal (PIP) joint. This is the joint at the junction of the hand and finger. In this case, the "jamming" of White's finger resulted with a sudden stretching of the right-middle finger. White sustained an axial loading force (distal to proximal) to the finger, combined with the finger being forced itno hyperextension.
White's finger will be splinted for up to three weeks and will follow that with another two weeks of range of motion and progressive resistance exercises. Good news is, no surgery is needed.
