Background: Proximal interphalangeal injury may result in malalignment of the phalanx axis of motion. In some instances, these fractures are treated with an external fixation method such as Suzuki-type fixation, during which the surgeon must perform X-rays to preserve the phalanx anatomical axis of motion.
Objectives: To assess the correlation between the palmar skin crease and the joint axis of the proximal interphalangeal joint (PIPJ) of the fingers opposing the thumb to improve the surgeons' perioperative planning procedure.
