Titanium and its alloys with various porous structures are one of the most important metals used in orthopaedic implants due to favourable properties as replacement for hard tissues. However, surface modification is critical to improve the osteointegration of titanium and its alloys. In this study, a bioactive magnesium coating was successfully fabricated on porous Ti6Al4V by means of arc ion plating, which was proved with fine grain size and high film/substrate adhesion. The surface composition and morphology were characterized by X-ray diffraction and SEM equipped with energy dispersive spectroscopy...

BACKGROUND: Total hip arthroplasty is an increasingly common procedure. The large number of cases inevitably includes patients who require filling of their acetabular defect even in their primary surgery. The use of a utogenous grafts and allografts as well as resistance rings requires patients to avoid loading the limb for a long time to enable implant integration. This disadvantage may be partially eliminated by using trabecular titanium implants. The aim of this paper is to present the outcomes of the use of trabecular titanium implants in primary hip arthroplasty...

BACKGROUND: The study aimed to compare sex differences in the morphology and spatial orientation of pelvic acetabula to advance the understanding of hip anatomy. MATERIAL AND METHODS: The study was based on three-dimensional reconstructions of computed tomography images of 50 female and 50 male acetabula. The images were used for spatial analysis of hip acetabula relative to the base of the sacral bone as the plane of reference. Statistical analysis was performed to compare angles relevant to the actual axis of the acetabulum (inclination angle, anteversion angle, tilt angle) as well as the volume and inner surface area of the acetabulum...

BACKGROUND: With the changing delivery of orthopaedic surgical care, there is a need to define the knowledge and competencies that are expected of an orthopaedist providing general and/or acute orthopaedic care. This article provides a proposal for the knowledge and competencies needed for an orthopaedist to practice general and/or acute care orthopaedic surgery. METHODS: Using the modified Delphi method, the General Orthopaedic Competency Task Force consisting of stakeholders associated with general orthopaedic practice has proposed the core knowledge and competencies that should be maintained by orthopaedists who practice emergency and general orthopaedic surgery...

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology...

OBJECTIVE: Perioperative goal directed therapy (PGDT) has been demonstrated to improve postoperative outcomes and reduce the length of hospital stays. The objective of our analysis was to evaluate the cost of complications, derived from French hospital payments, and calculate the potential cost savings and length of hospital stay reductions. METHODS: The billing of 2,388 patients who underwent scheduled high-risk surgery (i.e. major abdominal, gynaecologic, urological, vascular, and orthopaedic interventions) over three years was retrospectively collected from three French hospitals (one public - teaching, one public, and one private hospital)...

BACKGROUND: Hallux rigidus can be treated using several different methods and the best treatment option depends on the severity of degenerative changes of the metatarsophalangeal (MTP) joint. However, the ideal operative option for advanced hallux rigidus remains debatable. This prospective study was performed to evaluate the intermediate-term clinical outcomes of distal metatarsal osteotomy used as a joint-preserving method for the treatment of advanced hallux rigidus. METHODS: Forty-two cases (39 patients) were followed for more than 3 years after distal metatarsal dorsiflexion osteotomy for advanced hallux rigidus of grade III-IV...

OBJECTIVES: Malrotation of the femoral component can result in post-operative complications in total knee arthroplasty (TKA), including patellar maltracking. Therefore, we used computational simulation to investigate the influence of femoral malrotation on contact stresses on the polyethylene (PE) insert and on the patellar button as well as on the forces on the collateral ligaments. MATERIALS AND METHODS: Validated finite element (FE) models, for internal and external malrotations from 0° to 10° with regard to the neutral position, were developed to evaluate the effect of malrotation on the femoral component in TKA...

Titanium is a material commonly used for dental and orthopaedic implants. However, due to large differences in properties between the titanium metal and the natural bone, stress shielding has been observed in the surrounding area, resulting in bone atrophy, and thus has raised concerns of the use of this material. Ideally implant materials should possess similar properties to the surrounding tissues in order to distribute the load as the joint would naturally, while also possessing a similar porous structure to the bone to enable interaction with the surrounding material...

BACKGROUD: Surigical site infection has been a challenge for surgeons for many years, the prevalence of serum albumin <3.5g/dL has been reported to be associated with increased orthopaedic complications. However, the prognostic implications and significance of serum albumin <3.5g/dL after orthopaedic surgeries remain ambiguity. In this study, we performed a meta-analysis to access the predictive value of serum albumin level on SSI. METHODS: A basic data search was performed in PubMed and Web of Science, in addition, references were manually searched...
