From: Standard views do not suffice in assessing distal scaphoid articular cannulated screw penetration
A Standard anteroposterior and lateral fluoroscopy views of a percutaneous cannulated screw fixation of a scaphoid waist fracture showing minimal STT screw penetration. B Postoperative semi-pronated radiograph showing significant distal articular screw penetration and absence of screw thread purchase in the distal fragment. C Another example of significant distal articular screw penetration with subsequent delayed union of a scaphoid waist fracture
