The long-term efficacy of the treatment of chondral lesions is very important to prevent hip osteoarthritis. Microfracture, autologous chondrocyte transplantation, and direct chondral repair, among others, are techniques that have shown good results in some cases. We propose a technique to treat wave lesions through reverse microfracture, with bubble decompression and adherence of the natural scar from the detached cartilage.

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.

Background: Acromial stress fractures can occur after reverse total shoulder arthroplasty (RTSA). We performed this study to assess the incidence, risk factors, characteristics, and outcome of acromial stress fractures and reactions after RTSA.
Methods: We determined the incidence of acromial stress fractures and reactions in a cohort of patients who underwent RTSA, and assessed risk factors using a case-control design.

Reverse shoulder arthroplasty (RSA) has witnessed a significant advancement with the introduction of lateralisation techniques, aiming to enhance shoulder function and implant durability. Traditional medialised designs, following Grammont's principles, have encountered challenges such as scapular notching, reduced rotational strength, and instability. In contrast, lateralisation methods, which reposition the joint center of rotation laterally on the glenoid, humerus, or both, seek to improve deltoid leverage, optimize the rotator cuff muscles' length-tension relationship, and enhance joint stability.

Objective: To investigate the effects of bone density, plate bending degree and proximal screw type on the stress fracture of clavicle hook.
Methods: Three sows weighing between 45 and 50 kg were selected, from which a total of 40 rivs were collected. The 15 ribs of sows were divided into 3 groups according to bone density and bone hardness with 5 rivs in each group.
