Effects of Preoperative 3D Printing of Distal Intra-articular Radius Fractures on Quality of Fracture Reduction

We aim to evaluate the effect of a preoperative 3D printed Model (3PAS) of distal intraarticular radius fractures on quality of fracture reduction. Surgical procedure is equal in the 3PAS and in the conventional group. To evaluate the quality of fracture reduction each patient receives a postoperative CAT-scan.

Inclusion Criteria:Patient older than 18 yearsSurgery criteria fulfilledInformed consentIntra-articular Fracture of the distal radius (AO 23-B and 23-C) (also including Avulsion of the processus styloideus ulnae AO/OTA 2U3A1.1) in preoperative CAT-ScanExclusion Criteria:Patient does not want a surgical treatmentPatient does not want to participatePositive history for surgery due to injury of the hurt wrist beforehandPositive history for surgery due to injury of the opposite wrist beforehandAdditional injuries to the hand and forearm (except distal ulna fracture AO 2U3A1.1)PregnancyVulnerable peopleDistal ulna fracture (except AO 2U3A1.1)Extraarticular radius fracture (AO 23-A)Concomitant injuries which interfere with the planned aftercare (intubated for a long time, additional elbow or shoulder fracture)
