Failure causes in hip resurfacing arthroplasty – retrieval analysis
Metal–on–metal hip resurfacing arthroplasty represents an alternative treatment option for young and active patients with osteoarthritis. The advantages of metal–on–metal hip resurfacing arthroplasty include lower wear rate, restoration of anatomic hip biomechanics, preservation of bone stock for subsequent revision procedures, and enhanced stability due to the larger diameter of articulation. ...

Surgeon Testimonials for the Archer CSR Total Shoulder System - Case Study
For this procedure I used Catalyst's Archer CSR system for a total shoulder arthroplasty using a lesser tuberosity osteotomy repair with a screw-and-suture technique. Post operatively this patient did very well. He had return of full range of motion at 12 weeks. He was able to return to all his activities, including sporting activities as well as lifting, pushing and ...

Bone cement: an overview
Polymethylmethacrylate bone cement is a widely utilised material in the field of orthopaedic surgery and specifically total joint arthroplasty. Despite this, its mechanical properties are poorly understood by the end-user and there is controversy over the manner in which the material should be tested and the effects some commonly used techniques have on its mechanical properties. This article ...

New Manuscript: Manipulation Rate is Not Increased After Customized Total Knee Arthroplasty - Case Study
Background Manipulation under anesthesia (MUA) is a standard treatment for arthrofibrosis after total knee arthroplasty (TKA), with reported rates of 1.5-6%. Customized TKA may have better outcomes by matching individual patient anatomy. However, a previous study reported an unacceptably high rate of MUA for customized TKAs. This study reports the incidence of MUA in a large cohort of second ...

Surgeon Testimonials for the Archer CSR Total Shoulder System - Case Study
Below are several case studies and testimonials from actual surgeons performing total shoulder arthroplasties using the Archer™ CSR Total Shoulder System. The utilization of the anatomic Archer CSR humeral implant a/lowed for adequate bone stock retention to complete an anatomic transosseous supraspinatus repair and remove all of the patients painful pathology in one procedure. The patient ...

An autonomically-healed PMMA bone cement: influence of the crystal size of Grubbs' catalyst on fracture toughness and polymerisation rate
In this study, it was shown that the concept of autonomic healing of a neat polymeric material, which was introduced by White et al. (2001) could be applied to poly methyl methacrylate (PMMA) bone cement. The bone cement brand used – Surgical Simplex®P – is one that is widely used in cemented arthroplasties; the healing agent used was 2.0 wt.% dicyclopentadiene (DCPD), encapsulated in poly ...

Part 1: In-vitro release of gentamicinpalmitate coating in uncemented titanium implants
Microporous surfaces of commercially available uncemented Tilastan® implants were coated with gentamicinpalmitate. The roughness of the titanium implant surfaces remained largely intact. During the first few days, the gentamicin release was comparable to the elution of this antibiotic from commercially available PMMA bone cements. Compared to PMMA cements, the implants coated with the ...

Long-Term Outcomes Following Lumbar Nucleus Replacement
Abstract Background Nucleus replacement devices are designed to replace the native pain-generating lumbar nucleus while preserving the annulus fibrosus, endplates, and natural motion. The DASCOR Disc Arthroplasty Device seemed to perform well clinically but was discontinued in 2009. While there are no commercially available NRDs today, the potential advantages of using such devices have ...

A New Concept of Mosaicplasty: Autologous Osteoperiosteal Cylinder Graft Covered With Cellularized Scaffold
Abstract: A concern regarding osteochondral autograft transfer for chondral defects is donor-site morbidity of the knee, the most common source of the autograft. To avoid the drawbacks of osteochondral autograft transfer, a cylindrical osteoperiosteal graft harvested from the iliac crest covered by a same-sized cylinder of hyaluronic acidebased polymer scaffold pretreated with bone marrow ...

Value-Based Robotics, Pt.4: Micromate™ - Bringing Usability To The Operating Room
Our Value-Based Robotics series advances towards the actual clinical use of robotics and issues concerning practicality and surgeon onboarding and training. It is generally accepted that robotic surgical systems enable minimally invasive surgery and improve outcomes, including shorter recovery times, less scarring, and reduced healthcare costs. This being said, the jury is still out on whether ...
