Traction-induced hypertension in children.

Fifty-seven patients under treatment by traction were monitored for elevation of blood pressure. Hypertension developed in 39 of these patients (68%). Three patients required antihypertensive therapy to control the elevated blood pressure. The blood pressure returned to normal after discontinuation of traction. Sixty patients hospitalized for nonorthopedic problems who were not being treated by traction constituted the control group; seven of these patients (12%) had elevated blood pressure. Recognition of traction-induced hypertension is important to avoid not only its consequences but unnecessary diagnostic procedures as well.
