Cementless surface replacement arthroplasty(Copeland CSRA) for osteoarthritis of the 

shoulderOfer Levy, Stephen A. Copeland, Reading, United Kingdom

Radiographically, one humeral implant and three glenoid implants had evidence of

loosening. Four revisions were performed in the total shoulder replacement group.

No revision surgery was needed in the hemiarthroplasty group

Between 1986 and 1997, 79 CSRAs

Revision rate TSA : 9.5 %Revision rate HHR : 0 %

“Radiographic evaluation did not demonstrate any case of

obvious loosening of the implant at any time-period.”

ONE shoulder ONE shoulder was converted to a stemmed total shoulder arthroplasty at twenty-four

months because of pain, but the implant was not loose at the revision.

Revision rate 2.8 %

Current Concepts ReviewShoulder Resurfacing

“The revision rates of humeral resurfacing prostheses appear to be comparable with, or better than, those of stemmed prostheses.”

1) loosening of humeral and/or glenoid component2) glenoid erosion

3) infection 4) fracture

5) improper implant size

Therefore, it is necessary for us to do the minimum to get the maximum, and whatever we do we must have a fall-back procedure and it must be easily revisable.

CONCLUSIONICONCLUSIONI--22• Impianto “non facile” (varo,valgo, over-size)

• Corretto “bilanciamento” (release) come nelle

protesi tradizionali

• Evitare l’overstuffing (usura glenoidea, dolore,

stress sulla cuffia)

• Resurfacing TSA: tecnicamente più difficile, ma

potrebbe fornire risultati migliori

• Necessità di nuovi design
