Current cementing techniques in hip hemi-arthroplasty

To assess the use of modern cementing techniques in hip hemi-arthroplasty a postal questionnaire was sent during 1998 to all British Orthopaedic Training Association (B.O.T.A.) members regarding use of cement, type of cement, bone preparation and cementing technique. The results of this survey were compared to a similar survey in 1994 to assess any change in practice. Two hundred and eighty-six trainees responded to the 1998 survey, 352 to the 1994 survey. The use of uncemented prostheses had decreased from 31.3 in 1994 to 21.7% in 1998. Normal viscosity Palacos cement remains the most common cement in use, 64.3% in 1998. The use of antibiotic loaded cement has increased from 53.7 in 1994 to 67.9% in 1998. For bone preparation 47.3% of trainees in 1998 used a modern technique (syringe irrigation/pulsed lavage, brushing, gauze packing) compared to 35.1% in 1994. Modern cement insertion (retrograde gun, cement restriction and sustained pressure) was carried out by 39.3% in 1998 compared to 28.5% in 1994. Overall 27.2% of trainees used modern cementing techniques in hip hemi-arthroplasty, compared to 19.4% in 1994. Modern cementing techniques are used by a minority of British orthopaedic trainees, but in comparison to 1994 their use has increased.
