With proper attention to detail, complications are rare. Common technique errors include: failure to properly locate the screws, thus reducing the quality of the fixation or endangering the joint or soft tissues; failure to adequately countersink the screw head, resulting in bending; failure to adequately engage the transcortex, with stripping of the threads from the bone; and failure to maintain aseptic technique resulting in postoperative infection. Even with a less than ideal technique, healing is often still attainable. Degenerative arthritis is rare, but painful non-union of the articular surface of the fetlock can occur if adequate compression is not achieved.
The prognosis for resumption of athletic activity after internal fixation of simple proximal phalanx fractures is excellent. More complicated fractures carry a more grave prognosis commensurate with their severity.
