The condyle is part of the finger phalanx adjacent to the joint.
Easy to underestimate, finger condyle fractures should probably be treated surgically every time. The condyle may not look too badly displaced initially, however these fractures are known to do badly without surgery. Alignment may easily get worse and delay in treatment causes persistent finger stiffness.
This is an example of a finger condyle fracture in a young man.
The goal of fixation is to anatomically reduce the fracture fragments, and to start early motion of the finger. Nonsurgical treatment with a cast is a possibility, and may lead to a good radiographic outcome - but at the cost of losing the ability to move the joint.
In this particular case, the fracture was approached dorsoulnarly, between the central slip and the lateral band. Below is an xray with three tiny screws providing stable fixation.
He was treated promptly, he healed without problems, and gained full pain free motion. Physical therapy with finger motion was started the day after surgery.
