BACKGROUND The routine removal of orthopaedic fixation devices after fracture healing remains an issue of debate. There are no evidence-based guidelines on this matter, and little is known on surgeons' practice and perceived effectiveness of implant removal in different clinical settings. METHODS A 41-item questionnaire was distributed to 730 attendees of the AO Principles and Masters Courses...

The development of computational and numerical methods provides the option to study the contact mechanics and wear of hip resurfacing devices. The importance of these techniques is justified by the extensive amount of testing and experimental work required to verify and improve current orthopaedic implant devices. As the demands for device longevity is increasing, it is as important as ever to ...

Osseointegration refers to the direct bonding between titanium implants and bone, making it one of the key factors for the success of reconstructive and regenerative orthopaedic and dental surgeries [1]. Resolving the implantbone interface with high chemical or spatial resolution enables a clearer determination of bone growth mechanisms at the implant interface and optimal modification of impl...

Following the tradition of the IDES European Hip Registry inaugurated by M. E. Müller in the 1960s, the Institute for Evaluative Research in Orthopaedic Surgery at the University of Bern started a new era of data collection using internet technology (www.memdoc.org). With support of the Swiss Orthopaedic Society, the pilot of the Swiss Orthopaedic Registry was conducted, and in cooperation with...

Removal of metalwork is one of the commonest orthopaedic elective procedures with patients often requesting to keep their implants. Five hundred consecutive patients who had removal of their orthopaedic implant between April 1994 and March 2000 were contacted by post. Three hundred and seventy-two responded (response rate 74%). Two hundred and thirty-nine patients (64%) had metalwork extracted ...

Background: There are a number of different implant choices for surgical treatment of distal radius fractures, oftendetermined by surgeon preference or availability. Although no one volar plate demonstrates superior outcomes, thereare significant cost differences absorbed by hospitals and surgical centers. This purpose of this study is to characterizethe economic implications of implant selecti...

Aims And Objectives:To assess the incidence of postoperative surgical site infection following implant surgery in closed fractures. • To determine whether various risk factors & lab investigations are associated with development quantify contribution to probability Materials Methods:This study entitled “A Prospective Analysis Risk Factors for Post-operative Surgical Site Infection Implant...

High-energy injuries can result in complete or partial loss of the talus. Ipsilateral fractures to the lower limb increase the complexity of surgical management, and treatment is guided by previous case reports of similar injuries. A case of complex lower-extremity trauma with extruded and missing talar body and ipsilateral type IIIB open tibia fracture is presented. Surgical limb reconstructio...

We conducted histologic and histomorphometric studies to evaluate the osteointegration of gradient coatings composed of bioactive glass and nanohydroxyapatite (BG-nHA) on titanium-alloy orthopaedic implants and surrounding bone tissue in vivo. Titanium-alloy implants with a gradient coating (gradient coating group), uncoated implants (uncoated group), and implants with a conventional hydroxyapa...

The longevity, success, or failure of an orthopaedic implant is dependent on its osseointegration especially within the initial six months of the initial surgery. The development of strains plays a crucial role in both bone modelling and remodelling. For remodelling, in particular, strains of substantial values are required to activate the osteoblastic and osteoclastic activity for the osseoint...
