Article Abstract
Purpose: This study aimed to evaluate the outcomes of dual plating for unstable distal femoral fractures via a subgroup analysis between periprosthetic and non-periprosthetic fractures.
Methods: This retrospective cohort study analyzed the outcomes of dual plating for unstable distal femoral fractures among 49 consecutive patients (43 women and 6 men) enrolled from July 2008 to August 2020. The patients were divided into periprosthetic (group P, n = 29) and non-periprosthetic (group N, n = 20) groups. The radiographic outcomes included the mechanical lateral distal femoral angle (mLDFA) and union rate based on the computed tomography findings. The clinical parameters included the knee range of motion and knee society score (KSS).
Results: The mean patient age was 71.1 years, and the average follow-up period was 37 months (range, 12-138 months). Union was achieved in 47 patients (96%). The average final mLDFA was 90.5° in group P and 88.3° in group N. The average final knee range of motion was 130° in group P and 107° in group N. The average final KSS was 73.8 in group P and 87.1 in group N.
Conclusion: Dual plating for distal femoral fractures yielded an excellent union rate and limb alignment with a low complication rate.

Background: Umbilical arterial catheterisation is a common intervention performed in the neonatal intensive care unit (NICU) especially in extremely preterm and extremely low birth weight neonates. Rarely catheter fracture or breakage can occur, leaving behind part of the catheter in the aorta. A handful of cases have been reported in the literature, with the majority being managed surgically.

The bony consolidation of fractures depends on various factors. Under optimal conditions fracture healing takes place within a few weeks. An essential requirement for fracture healing is the restoration of adequate biomechanical stability with an interfragmentary movement which is as ideal as possible.

Atraumatic bilateral osteonecrosis of the femoral head (ONFH) is a rare phenomenon whose etiology is not fully understood. In this report, we describe the case of a 75-year-old female patient who developed rapidly onset bilateral ONFH after intra-articular corticosteroid injections. She was treated with staged bilateral total hip arthroplasty.

Purpose: The purposes of this study were threefold: (1) to evaluate the influence of femoral antecurvature on coronal alignment changes following supracondylar femoral derotational osteotomy (FDO); (2) to investigate the combined effects of derotation angle and osteotomy orientation in relation to femoral antecurvature and (3) to propose a practical strategy for minimising valgus deviation after FDO based sagittal femoral bowing.
Materials And Methods: Sixty-six cadaveric femoral computed tomography (CT) scans were analysed using three-dimensional (3D) simulation. Femurs were classified into three groups based on the degree of antecurvature using the distal diaphyseal angle (DDA).
Effect of Femoral Component Flexion in Robotic-Assisted Total Knee Arthroplasty on Retrograde Intramedullary Nail Sagittal Trajectory Angulation.

Background: In robotic-assisted total knee arthroplasty (RA-TKA), the femoral prosthesis is positioned independent of the intramedullary canal and frequently in flexion for function optimization. Femoral prosthesis flexion displaces retrograde intramedullary nail (rIMN) start point posteriorly potentially exacerbating hyperextension deformity in periprosthetic fracture (PPFx) fixation. The aim of this study was to determine the relationship between RA-TKA femoral component flexion with rIMN sagittal trajectory angulation.
