The routine use of surgical drains in total hip arthroplasty remains controversial. They have not been shown to decrease the rate of wound infection significantly and can provide a retrograde route for it. Their use does not reduce the size or incidence of post-operative wound haematomas. This prospective, randomised study was designed to evaluate the role of drains in routine total hip arthroplasty.

We investigated 552 patients (577 hips) undergoing unilateral or bilateral total hip arthroplasty who had been randomised to either having a drain for 24 hours or not having a drain. All patients followed standardised pre-, intra-, and post-operative regimes and were independently assessed using the Harris hip score before operation and at six, 18 and 36 months follow-up.

The rate of superficial and deep infection was 2.9% and 0.4%, respectively, in the drained group and 4.8% and 0.7%, respectively in the undrained group. One patient in the undrained group had a haematoma which did not require drainage or transfusion. The rate of transfusion after operation in the drained group was significantly higher than for undrained procedures (p < 0.042). The use of a drain did not influence the post-operative levels of haemoglobin, the revision rates, Harris hip scores, the length of hospital stay or the incidence of thromboembolism. We conclude that drains provide no clear advantage at total hip arthroplasty, represent an additional cost, and expose patients to a higher risk of transfusion.

Although drains date back to the Hippocratic era, their routine use remains controversial in total hip arthroplasty. The literature suggests that they can provide a retrograde route for infection as well as decreasing the organism count required to develop an infection. The use of drains has not decreased the size of wound haematomas at day five on ultrasound or the incidence of massive wound haematomas. Neither have they been shown to significantly decrease wound infections. This consecutive prospective randomised study was designed to evaluate what role drains have in the management of patients undergoing hip arthroplasty.

A total of 577 patients undergoing unilateral or bilateral hip arthroplasty were evaluated in a randomised prospective trial of drain versus no drain, between September 1997 and December 2000. All patients had a standardised pre, inter and post operative regime and were independently assessed using the Harris hip score and SF36 pre-operatively, at discharge and at six months post surgery.

The superficial and deep infection rate of 6. 4% and 0. 4% was seen in those drained and 7. 1% and 0. 7% in the non-drained group. Only one patient sustained a clinical haematoma that did not requiring drainage or transfusion in the non-drain group. The transfusion rate in those drained was 33. 0% compared to 26. 4% in those not drained. There was no statistical advantage in using a drain P> 0. 05 regarding these variables or in the length of stay, SF36 or Harris hip scores at pre-op and six months. Using a drain did significantly increase the likelihood of requiring a transfusion P< 0. 05.

In conclusion drains provide no statistical advantage whilst represent an additional cost and expose hip arthroplasty patients to an unacceptable risk of infection and transfusion.

We reviewed 286 consecutive patients with a fracture of a pubic ramus. The overall incidence was 6.9/100 000/year in the total population and 25.6/100 000/year in individuals aged over 60 years. The mean age of the patients was 74.7 years and 24.5% suffered from dementia. Women were affected 4.2 times more often than men. After injury, geriatric rehabilitation was frequently required and although most surviving patients returned to their original place of residence, their level of mobility was often worse. The overall survival rates at one and five years were 86.7% and 45.6%, respectively. Multiple logistic regression analysis showed that age and dementia were the only independent significant factors to be predictive of mortality (p < 0.05).

Patients with a fracture of a pubic ramus had a significantly worse survival than an age-matched cohort from the general population (log-rank test, p < 0.001), but this was better than patients with a fracture of the hip during the first year after injury, although their subsequent mortality was higher. Five years after the fracture there was no significant difference in survival between the two groups.
