No effect of drains on the postoperative hematoma volume in hip replacement surgery: a randomized study using scintigraphy.

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.

Primary bone grafting does not improve the results in severely displaced distal radius fractures.

We prospectively randomised 45 patients ages 20-70 years with distal radius fractures of Older type III and IV to one of two treatment groups. One group was treated with closed reduction, primary bone grafting, and external fixation for 3 weeks, followed by a plaster cast that allowed volar flexion, for an additional 3 weeks. The other group was treated with closed reduction and external fixation for 6 weeks.

Lateral position reduces blood loss in hip replacement surgery: a prospective randomized study of 74 patients.

We performed a prospective randomized study of 74 patients undergoing hip replacement surgery and compared the perioperative blood loss in the lateral position with that in the supine position. The surgeons and surgical technique were the same in the two groups. The patients operated on in the lateral position had a significantly lower total blood loss, on average 201 ml less.

The Wagner revision prosthesis consistently restores femoral bone structure.

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.
