Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

The best treatment method for reverse obliquity intertrochanteric fractures (ROIFs) is still under debate. Our team designed the modified proximal femoral nail (MPFN) specially for treating such fractures. The objective of this research was to introduce the MPFN device and compare the biomechanical properties with Proximal Femoral Nail Antirotation (PFNA) and InterTAN nail via finite element modelling.

Case: A 34-year-old man, amateur weight lifter presented with acute worsening of right shoulder pain after 5 months of prodromal, progressive, atraumatic pain. Imaging showed a short oblique proximal third humeral shaft fracture without evidence of other osseous abnormalities. He was treated operatively with open reduction and internal fixation, healed uneventfully, and returned to weight lifting within 3 months.

Introduction: Numerous orthopaedic procedures including dynamic hip screw plating and various osteotomies require placement of a reference guide pin or K wire to direct bone cuts or for drilling screw holes. Appropriate positioning of these wires is a critical component of surgery. Irrespective of whether one is a seasoned surgeon or an apprentice, these wires often need repositioning and readjustment.

Pediatric elbow fractures are quite common, accounting for up to 34% of bone fractures in children. Among these, acute lateral humeral condyle (LHC) fractures represent up to 22%. The accurate diagnosis and early treatment of LHC fractures are crucial due to the potential for abnormal growth and significant long-term impacts on joint motion.
