The Sofield-Millar operation in osteogenesis imperfecta - A modified technique

We have reviewed the results of the Sofield-Millar operation on 58 long bon es in ten patients. If more than three osteotomies were undertaken the time to union of the bone was significantly prolonged (p < 0.001) with signific ant thinning of the bone (p < 0.02). We have used a modified technique in order to minimise surgical trauma and devascularisation of the bone. The rod is introduced under the control of a n image-intensifier. Small surgical exposures are made only at the sites of corrective wedge osteotomies. The number of osteotomies is kept to the min imum.
