Open technique for supra-acetabular pin placement in pelvic external fixation: a cadaveric study.

J Orthop Traumatol 2022 Mar 14;23(1):14. Epub 2022 Mar 14.

Department of Orthopaedics, Faculty of Medicine, Thammasat University, 99 Moo 18, Khlong Nueng, Khlong Luang, 12120, Pathumthani, Thailand.

Background: Standard supra-acetabular pin placement still needs fluoroscopic guidance, which is technically demanding for an untrained surgeon due to the unfamiliar fluoroscopic view and the risk of damaging some structures. The risks associated with the open technique without fluoroscopy have not yet been investigated, despite the palpable entry point and large bony corridor for rapid insertion in the limited time available for the management of unstable pelvic fracture patients. The aim of this study was to compare the open technique without fluoroscopy to the fluoroscopically assisted percutaneous technique for the positioning of supra-acetabular screws in cadavers without pelvic instability.
