Can tibial tantalum cones eventually eliminate the adjuvant use of metallic augments for AORI type 2B/3 metaphyseal defects??-A novel surgical technique and case series.

Background: For extensive metaphyseal defects, the use of tantalum cones is usually combined with adjuvant stems which may be cemented/cementless and metallic bone augments for additional stability. A Tibial baseplate-Cone construct with proud tibial cones and without metallic augments has been described for AORI type 2B/3 tibial defects.

Methods: A case series analysis of 6 patients with AORI type 3 defects treated with unstepped proud Tantalum tibial metaphyseal cones without metallic wedges/full width augments.

Influence of prosthetic design on squeaking after ceramic-on-ceramic total hip arthroplasty.

Squeaky ceramic-on-ceramic (COC) total hips have received much recent publicity, and implant design may be implicated. We reviewed 270 consecutive COC total hip arthroplasties in 233 patients comparing 4 implant combinations representing 4 manufacturers. A cohort (n = 45) of Stryker Trident acetabular cups paired with Stryker Accolade femoral stems showed a dramatically higher incidence of "problem squeaking"--defined as always audible to others and occurring at least once per week--with a 35.

Early results of 1000 consecutive, posterior, single-incision minimally invasive surgery total hip arthroplasties.

One thousand consecutive cementless total hip arthroplasties performed in 759 patients using a posterior, single-incision, minimally invasive surgical approach were followed prospectively for a minimum of 2 years. All surgeries were performed using a tapered, titanium, cementless femoral component and a press-fit, ingrowth acetabular component. Mean patient age was 62.

The tapered press fit total hip arthroplasty: a European alternative.

The tapered rectangular press fit femoral component design of Karl Zweymüller remains highly successful since its inception in 1979. The longitudinal taper and rectangular cross-section provide unequaled primary stability, which promotes consistent secondary osseointegration to the grit-blasted titanium surface, even in osteoporotic bone. The "fit without fill" concept provides for bone conservation and preservation of the intraosseous blood supply by compaction, rather than removal, of the metaphyseal cancellous bone.
