Mittelmeier's ceramic hip prosthesis.

The results are reported of 59 non-cemented ceramic hip prostheses, 29 of which have a follow-up of from one to three years. The technical details are described and the advantages of this type of prosthesis over the older cemented types are discussed. The results of this limited series, albeit with a comparatively short follow-up, are sufficiently encouraging to recommend the use of this prosthesis, when the indications are correct, in place of the cemented types.
