The success of any implant, dental or orthopaedic, is driven by the interaction of implant material with the surrounding tissue. In this context, the nature of the implant surface plays a direct role in determining the long term stability as physico-chemical properties of the surface affect cellular attachment, expression of proteins, and finally osseointegration. Thus to enhance the degree of ...

Titanium implants are widely used in dental clinics and orthopaedic surgery. However, bone formation surrounding the implant is relatively slow after inserting the implant. The current study assessed the effects of bone marrow stromal cells (BMSCs) with forced expression of special AT-rich sequence-binding protein 2 (SATB2) on the osseointegration of titanium implants. To determine whether SATB...

INTRODUCTION Dental implants are increasingly used to restore missing dentition. These titanium implants are surgically installed in the edentulous alveolar ridge and allowed to osteointegrate with the bone during the healing phase. After osseo-integration, the implant is loaded with a prosthesis to replace the missing tooth. Conventional implant treatment planning uses study models, wax-ups an...

Endosseous cementless implants are widely used in orthopaedic, maxillofacial and oral surgery. However, failures are still observed and remain difficult to anticipate as remodelling phenomena at the bone-implant interface are poorly understood. The assessment of the biomechanical strength of the bone-implant interface may improve the understanding of the osseointegration process. An experimenta...

Prevention of bacterial colonization and formation of a bacterial biofilm on implant surfaces has been a challenge in orthopaedic surgery. The treatment of implant-associated infections with conventional antibiotics has become more complicated by the emergence of multi-drug resistant bacteria. Antimicrobial eluting coatings on implants is one of the most promising strategies that have been atte...

BACKGROUND The morphologic features of the proximal femur are used in preoperative planning prior to total hip arthroplasty. The standard commercially available marketed prostheses sometimes may not be the best fit to all subjects because of the large anatomic variation among different population. Orthopaedic surgeons always stress the need for a proper implant-patient match in hip joint replac...

Introduction: Orthopaedic surgical activity has been significantly affected by COVID-19 pandemic. The decision to perform operative interventions is based on balancing risk benefit the patient and health care workers. Though different guidelines have published, there a lack of reliable data orthopaedic activities. Our study aimed evaluate impact pandemic surgeries comparing with previous year. ...

The focus of this review are allergic reactions to orthopaedic-surgical metal implants. The spectrum of metal implant associated potential allergic reactions encompasses eczema, impaired wound and fracture healing, infection-mimicking reactions, effusions, pain and loosening. Nickel, cobalt and chromium seem to be the predominant eliciting allergens. Despite the growing number of respective pub...

Metals with certain porosity are a new class of materials extremely low density and unique combination excellent mechanical, thermal, electrical, biocompatible properties. Absorption impact shock energy, dust fluid filtration, construction materials, most importantly, implants all potential applications for metallic foams. An orthopaedic implant made foam can provide an open-cell structure that...

Hip fractures in the elderly population remain a significant public health concern. With a rise in the incidence of osteoporosis, orthopaedic surgeons must be familiar with different fixation options in both trauma and arthroplasty to minimize complications and implant failure following treatment of femoral neck fractures. Cemented hip hemiarthroplasty is a reliable method for restoring functio...
