Hip arthrodesis in adolescents using external fixation.
Between 1994 and 1998, seven adolescents underwent hip arthrodesis with the use of an external fixator. Mean time of follow-up was 24.0 months after surgery. The duration of fixation and time to fusion were 6.6 months (range, 5-9.5 months) and 8.0 months (range, 5.2-15 months), respectively. At most recent follow-up, there was a significant improvement in the mean modified Harris hip score, in which the maximum score is 91 points after omitting 9 points for hip range of motion and deformity, from 25.7 before surgery to 66.7 after surgery (p < 0.01). The advantages of this procedure include (i) the ease and accuracy of obtaining the proper position for fusion, (ii) the ability to lengthen the affected leg at the same time, (iii) the diminished likelihood of compromising future hip operations, and (iv) the ability to ambulate and bear weight throughout the treatment course. We recommend this method of hip arthrodesis with external fixation for patients with intractable hip pain necessitating this procedure.
