Department of Orthopedic Surgery, Kurume University Medical Center, Kurume, JPN.
With the increase in life expectancy, the number of elderly individuals undergoing hemiarthroplasty and total hip arthroplasty has risen, leading to a higher incidence of implant-related fractures. Diagnosing fractures, especially occult and non-displaced ones, can be challenging even with advanced imaging techniques. This report describes the diagnostic challenges and surgical management of a rare combination of periprosthetic femoral fracture and an ipsilateral acetabular occult non-displaced fracture.

Background: A robotic arm-assisted and a computed tomography (CT)- based navigation system have been reported to improve the accuracy of component positioning in total hip arthroplasty (THA). However, no study has compared robotic arm-assisted THA (rTHA) to CT-based navigated THA (nTHA) concerning accuracy of cup placement and acetabular fractures using the direct anterior approach (DAA). This study aimed to compare the accuracy of cup placement and the presence of intraoperative acetabular fractures between rTHA and nTHA using DAA in the supine position.

Introduction: Examination under anesthesia (EUA) (stress fluoroscopy) is commonly done after pelvic ring injury to identify occult instability because unstable disruptions may displace causing morbidity. The force applied during EUA for these injuries has not been standardized. The purpose of this study was to examine the forces used during the EUA by experienced orthopaedic trauma pelvic surgeons.

Department of Traumatology and Reconstructive Surgery, Berufsgenossenschaftliche Unfallklinik Tübingen, Tübingen, Germany.
Background: Raised complication rates have been reported for total hip arthroplasty (THA) in posttraumatic hip joints after acetabular fractures with prior open reduction and internal fixation (ORIF). The present study evaluated (I) postoperative surgical site infection and the risk of early infection following THA in posttraumatic hip joints after acetabular fractures and (II) the discriminatory ability of preoperative C-reactive protein (CRP) blood levels for periprosthetic joint infection (PJI).
Materials And Methods: Patients were included who had undergone THA (2014-2019) after prior ORIF, and nonsurgically treated acetabular fractures.
Relationship Between Acetabular Hounsfield Unit Values and Periprosthetic Fractures in Cementless Total Hip Arthroplasty: A Matched Case-Control Study.

Department of Orthopedic Surgery, Showa University School of Medicine, Shinagawa-ku, Tokyo, Japan.
Background: The association between regional bone status around the acetabulum and the incidence of intraoperative acetabulum fractures has not been extensively studied. We investigated the association of Hounsfield unit (HU) values on computed tomography in the regions of the acetabulum with periprosthetic fractures.
Methods: We retrospectively reviewed records of 301 consecutive patients who underwent cementless total hip arthroplasty between October 2016 and December 2020.
