The short-term results are reported for 43 hip revision operations with the long-stemmed Wagner prosthesis. The patients were followed-up for an average of 25 months. The Charnley scores were; pain 5.2, movement 4.0 and walking 4.0. All patients except one showed abundant new bone formation. The stem subsided more than 20 mm in 5 patients and in 22 the subsidence was less than 5 mm. The major complication was dislocation, which occurred in 9 patients; 8 of these were reoperated and from then on remained stable.

In a prospective randomized study we used erythrocyte scintigraphy to evaluate whether drainage reduced the hematoma volume after total hip arthroplasty. 12 patients were left without drains and 10 patients had two drains inserted, one below the fascia and one subcutaneously. We used tomographic registration (SPECT) to calculate the volume of the hematoma (erythrocytes) about 22 hours after surgery and found that drainage did not reduce the volume, but increased the need for blood transfusion.
