Surgical simulations are particularly appropriate for the large volume and expense of joint replacement procedures in orthopaedics. A first generation surgical simulator has been developed to model the implantation procedure for cementless acetabular and femoral components in total hip replacement surgery. The simulator is based upon finite element analysis and predicts the early postoperative ...

Introduction: Total knee arthroplasty (TKA) is common orthopaedic operations with low complication rates. In the preoperative knee, 90° flexion allows the popliteal artery (PA) to move safely backward from the tibia [1]. However, this surgery is in close proximity to the PA, the behavior of which during flexion of the prosthetic knee is poorly understand. Especially, there is little appropriate...

Primary bone sarcomas are rare tumors and surgical resection in combination with chemo radiation therapy is the mainstay of treatment. Some specific anatomical sites still represent a reconstructive challenge due to their complex three-dimensional anatomy. In recent years, patient instruments along 3D printing technology has come innovative techniques orthopaedic oncology. We retrospectively re...

This research presents a virtual reality simulator for total hip replacement surgery. The simulator supports a library of 3D hip stem models for different sizes and manufacturers. The 3D hip stems can be adjusted in size and shape by parametric software and sent for 3D printing. Biocompatible materials such as titanium enable the 3D printed stems to be directly implanted on patients. Currently ...

PURPOSE Degradation products of metallic biomaterials including titanium may result in metal hypersensitivity reaction. Hypersensitivity to biomaterials is often described in terms of vague pain, skin rashes, fatigue and malaise and in some cases implant loss. Recently, titanium hypersensitivity has been suggested as one of the factors responsible for implant failure. Although titanium hypersen...

The use of uncemented titanium endosseous implants for restorative dentistry and orthopaedic surgery has been the standard of care for several decades. Endosseous implantation using uncemented titanium prostheses is commonly performed in trabecular bone sites such as the jaws, vertebrae and ileum. Still, the mechanisms involved in this fascinating and unique interaction between a living tissue ...

Abstract Recent developments in the medical field of additive manufacturing (AM) have allowed creation patient-specific porous titanium implants for use field. With correct pore size such scaffolds are able to be integrated into surrounding bone. Two dogs were presented with atrophic non-union proximal ulna involving elbow joint due previous orthopaedic procedures severe complications that led ...

Abstract Background There is a reasonable evidence around oral/dental health and implant infection in orthopaedic cardiovascular surgery. Mesh hernia repair another area of surgical practice associated with permanent implant. The aim this SR was to review the mesh infection. Mehods study registered at Prospero. A systematic literature undertaken according PRISMA2020 statement. initial search id...

UNLABELLED For load-bearing orthopaedic applications, metal implants having an interconnected pore structure exhibit the potential to facilitate bone ingrowth and the possibility for reducing the stiffness mismatch between the implant and bone, thus eliminating stress-shielding effects. 3D printed solid and macro-porous Ti6Al4V implants were evaluated after six-months healing in adult sheep fem...

The success of many endosseous implants in orthopaedic and dental applications depends on the surface characteristics, as they affect osseous integration. Previous investigations indicated that a novel large-grit sand-blasted and acid-etched (SLA) titanium (denoted as SLAffinity-Ti) implant had better bone integration than that of a comparably shaped implant with a plasma-sprayed titanium surfa...
