AbstractThis study was performed to determine if picture archiving communication systems can provide a more accurate method of determining implant length for intramedullary tibial nailing. Postoperative radiographs of 40 patients who underwent intramedullary nailing of their tibial shaft fractures using picture archiving communication systems were retrieved. In phase one and two of this investigation, tibial nail lengths were measured using "measuring distance" and "measure calibration" tools displayed on the respective digital systems. Phase 3 of this study involved 5 tibial Sawbones (Pacific Research Laboratories, Vashon, Wash) radiographically captured on the picture archiving communication systems with a radiograph marker of known length. Using the "measuring distance" and "measure calibration" tools in phases one and two did not result in accurate measurements. Of 40 digital radiographic images measured and calibrated with the on-screen ruler and using the digital system tools, 100% of our measurements were inaccurate. An average of 19.4-mm and 10.6-mm difference was noted in uncorrected measurements on anteroposterior (AP) and lateral views, respectively. An average 25.8 mm and 15.7 mm was noted in calibrated (corrected) measurements on AP and lateral views respectively. Digitally measured and calibrated lengths were an average 22 mm and 25 mm greater from the actual known length of the tibial nail, respectively. Phase 3 of our study presented the most accurate results in length determination of tibial nail length.
