Accolade 1, taper problems

When will this be a global recall with the TMZF taper. Many failures and case reports in literature. Will Stryker inform the FDA ?
What about Accolade 2. It is the same taper ?

 

What are the taper problems that are exclusive to Accolade?
Also, would you please cite the case reports?

 

TMZF is not a taper.

 

Taper is made of TMZF titanium.
Case report in JOA, 2013, 'pseudotumour formation due to tribocorrosion....total hip replacements', cook et al. Two case reports of accolode tapers (with TMZF)
Joint implant surgery @ research foundation, 'Pseudotumor in metal on poly total hip arthroplasty' Clyburn.

Want more .......

 

Presented at AAHKS, fretting with large heads.

 

Ok, its a beta titanium, softer than Ti. The stem AND taper are made of TMZF .
That's why ABG, Rejevenate and now Accolade I will be a big problem

 

JOA, 2013, Cook et al, 'Pseudotumour Formation ...Total hip Replacements', two cases of accolade
Joint implant Surgery @ Research Foundation, 'Pseudotumour in metal on poly total hip arthroplasty', Clyburn, accolade taper failure TMZF case study

 

Accolade II not TMZF

 

but the taper is still the same size .
So, just because Accolade 2 is not TMZF, do we forget about the impending failures of Accolade 1 ??

 

You obviously have no idea what you're talking about.

Accolade has been used for years, and has been strykers #1 stem for quite some time. If this was a true stem problem, we would have seen this problem way before now. Fretting and corrosion is being talked about in the industry in general, especially in large diameter heads.

Also, in todays environment of constant legal concerns, accolade tmzf would be pulled and replaced w Accolade 2.

 

if you think this is only relates to the accolade then you are more retarded then your post. this problem has been circulating amongst the community for a couple years now. It isn't just relative to the Accolade, all trunnions used with metal heads are going to see this, not just stryker. why you think more and more surgeons want to use ceramic heads even if the patient isn't under 50 years of age

 

What about Meridian?


Stop reading attorney websites

 

Accolade I and II have the smallest tapers on the market. Couple that with 36mm + heads and which stem has the potential to fret the most. Read the literature, case reports dont lie. Read the 'langton' report.

 

Wtf are you talking about? It's a V40 taper which has been used by Stryker for years on all Howmedica stems post pca.

 

Yes a V40, but not the same size in contact area. Compare yourself and see !

 

What about the soon to be Exeter recall?

 

You guys are reaching. Ever seen an articuleze mini taper? The controversy surrounds large heads on 'modern' taper designs, not monoblock stems.

 

Read the papers quoted above. These are failures of Accolade I stems with fretting at the neck/head junction.
Accolade II will have the same problem, despite changing metal to Ti because the taper is the same (smallest in the industry) size.
Telling surgeons to start using Ceramic heads ...wow, good solution ?

 

EXETER!!

 

Do a quick search on femoral stems and 36 heads. Please post a direct link to the papers you mention.
