Objective: This study aims to evaluate the clinical outcomes of Vancouver B1 periprosthetic femoral fractures (PFF) treated with the Ortho-bridge system (OBS) internal fixation and assess the potential benefits of 3D printing technology in preoperative planning and surgical execution for these cases.
Method: This retrospective study analyzed 55 consecutive Vancouver B1 periprosthetic femoral fracture cases treated surgically at Yan'an Affiliated Hospital of Kunming Medical University (2014-2022) with minimum 1-year follow-up. Patients were divided into conventional ORIF (n = 21) and OBS fixation groups (n = 34), with the OBS group further stratified into standard procedure (n = 18) and 3D-printing-assisted (n = 16) subgroups.
Objective: To compare and analyze the Ortho-Bridge System (OBS) clinical efficacy assisted by 3D printing and proximal femoral nail anti-rotation (PFNA) of AO/OTA type 31-A3 femoral intertrochanteric fractures in elderly patients.
Methods: A retrospective analysis of 25 elderly patients diagnosed with AO/OTA type 31-A3 femoral intertrochanteric fracture was conducted from January 2020 to August 2022 at Yan'an Hospital, affiliated to Kunming Medical University. The patients were divided into 10 patients in the OBS group and 15 in the PFNA group according to different surgical methods.
