title: A method of evaluating possible pin penetration in slipped capital femoral epiphysis using a cannulated internal fixation device.
abstract: A technique that utilizes a newly designed cannulated screw with injection of radiographic dye through the screw cannula provides a reliable and practical method for detection and avoidance of pin penetration when operating on slipped capital femoral epiphyses. Adoption of this method minimizes the possibility of poor results occurring as a consequence of internal fixation.
