Macrophage inhibits the osteogenesis of fibroblasts in ultrahigh molecular weight polyethylene (UHMWPE) wear particle-induced osteolysis [PDF]

, 2019
Background In the ultrahigh molecular weight polyethylene (UHMWPE) prosthetic environment, fibroblasts affected by wear particles have the capacity of osteogenesis to reduce osteolysis.

Migrasomes, Matrix‐Bound Nanovesicles, and More: Messengers in the Matrix

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) and particles (EPs) are diverse micro‐ and nanoparticles that circulate in bodily fluids and can attach to, or be deposited onto, the extracellular matrix (ECM) and other surfaces. To date, the nomenclature and classification of matrix‐bound or matrix‐associated EVs and EPs (MEVPs) have been unclear, largely due to

Conservative treatment of periprosthetic femur fractures around metaphyseal short stems – A feasible option?

Trauma Case Reports, 2017
Periprosthetic femoral fractures are rare but significant events following total hip replacement. Metaphyseal short stems have recently been popularized as a bone preserving alternative to conventional uncemented total hip replacement.

Open Periprosthetic Knee Fracture: A Case Report and Review of the Literature

Geriatric Orthopaedic Surgery & Rehabilitation, 2020
Introduction: With the increase in knee and hip implants, these periprosthetic fractures will become more common especially as the population ages. Open periprosthetic fractures are rare and severe injuries and are more likely to be seen in high-energy ...

Baseline MDCT findings after prosthetic heart valve implantation provide important complementary information to echocardiography for follow-up purposes [PDF]

, 2016
Objectives: Recent studies have proposed additional multidetector-row CT (MDCT) for prosthetic heart valve (PHV) dysfunction. References to discriminate physiological from pathological conditions early after implantation are lacking.

Comparison between simulation results and DEXA investigation of the bone remodelling after implanting a cementless long stem hip prosthesis [PDF]

, 2013
Bone remodelling around a femoral prosthesis is one of the main reasons of aseptic loosening of the implant’s stem. The difference in stiffness between the bone tissue and the prosthesis leads to unload the periprosthetic bone and thus to decrease the ...

Creating Perforations in the Sclerotic Region of the Proximal Tibia During Total Knee Arthroplasty to Enhance Prosthesis Stability

Orthopaedic Surgery, Volume 17, Issue 5, Page 1397-1405, May 2025.
Abnormal stress in the proximal tibia modifies the bone mineral density distribution pattern, and drilling in the sclerotic region during total knee arthroplasty is correlated with enhanced prosthesis stability. ABSTRACT Objective In patients with varus deformity of the knee, the redistribution of the subchondral bone mineral density (BMD) of the tibia

Nightmare of repeated low-energy periprosthetic femoral fracture in a patient with severe osteoporosis – A lesson learned

Trauma Case Reports, 2020
We report an 85-year-old patient with severe osteoporosis who had suffered from multiple episodes of periprosthetic fracture of the femur. Revision fixation with long-spanning cable plate for bisphosphonate-induced atypical periprosthetic femoral ...

Customized Metal 3D Printed Total Wrist Prosthesis in the Treatment of Severely Destroyed Wrist: Design Rationale and Clinical Applications

Orthopaedic Surgery, Volume 17, Issue 5, Page 1536-1546, May 2025.
Four patients with severe wrist destruction from various causes were treated with customized 3D‐printed prostheses. In addition to the specific articular surface matching their original radiocarpal joint, two innovative proximal component designs were created to address different bone defects.
