Copeland Humeral Resurfacing Head

No other resurfacing shoulder has publications to back its claims, least of all 20 years clinical results.  The Copeland Shoulder is proven to restore natural joint anatomy and is the resurfacing shoulder of choice. 

The Copeland Shoulder has the added benefit of simple instrumentation and surgical technique, to aid the surgeon and theatre team.

The Copeland Shoulder is a cementless resurfacing implant, developed to mimic the natural shape of the normal humeral head and restore normal anatomy for arthritic patients.  It is the original resurfacing shoulder prosthesis, with a 20 year history¹, and is the resurfacing shoulder of choice worldwide.

Copeland Shoulder Design

The revolutionary design of the Copeland Humeral Resurfacing Head includes an Extended Skirted Rim for a circumferential press fit and a Tapered Cruciform Peg, to ensure a secure Primary Press Fit Fixation.

Other Key Benefits of this shoulder implant include:

• Closed Pore Porous Coating and Hydroxyapatite for minimal wear debris ingress and long term fixation^2,3
• Titanium Porous Coating for excellent biocompatibility⁽²⁾
• Cobalt Chrome and ArCom polyethylene articulation for minimal wear
• Top Loading System
• 8 Sizes of Prostheses available to mimic normal anatomy as closely as possible
   

Easy Conversion to a Stemmed Component:

• Remove resurfacing component only and replace with a stemmed implant; or
• Resect the Humeral Head and component together and continue with a stemmed implant

Copeland Shoulder Instrumentation & Technique

The Copeland Shoulder technique is minimally invasive and preserves bone stock, with the added benefit of simple colour-coded instrumentation to aid the surgical team.  The surgical technique is based on a 3-Step Bone Preparation:

1. Locate the centre of the Humeral Head
2. Ream to define and restore Humeral Head shape
3. Drill for central peg.
 

Proven Clinical Results for Copeland Shoulder Humeral Resurfacing Head

(1) Mullett H, Levy O, Raj D, Even T, Abraham R, Copeland S A, Copeland Surface Replacement of the Shoulder – Results of an Hydroxyapatite-Coated Cementless Implant in Patients over 80 years of age, International Congress of Shoulder and Elbow Society, Brazil, 2007
Highlights of this study include:

Between 1993 and 2002 a series of 209 shoulders underwent resurfacing arthroplasty.
==> 180 hemi arthroplasty
==> 29 total shoulders

• No humeral radio-luciencies witnessed throughout this series
• The survival rate of HA coating is 98% @ 10 years
• Kaplan Mier Analysis suggests 96.4% survival rate for the prosthesis @ 10 years
• The revision rate for the HA coated Mark IV, launched in 1993 is 2.6%. Moreover, revisions in OA are 0.7%, amounting to one revised prosthesis!
• Hemi and total arthroplasty were no different in terms of functional outcome in this series. 

Conclusion

There are still no luciencies reported since introduction of HA Coating.

OA patients still achieve the best functional scores

16% of the patients in this series had total shoulder arthroplasty, proving you can replace the glenoid with a Copeland Shoulder!
