Three-dimensional computed tomography reconstructions were done in the preoperative workup of five patients receiving Ilizarov correction for relapsed infantile Blount's disease. There were four girls and one boy with a mean age of 9 years 11 months. In all patients, the computed tomography reconstruction images made assessment of the deformity easier and revealed abnormalities not readily seen on plain radiographs. This information has particular relevance to medial plateau elevation using the Ilizarov frame because it is possible to correct a medial and posterior slope of the tibial plateau using this technique. Also, this imaging modality is safe, easy to do, and is a useful adjunct for planning before surgical correction of relapsed Blount's disease.
Deformity of the forearm due to growth disturbance of the ulna occurs in a number of conditions such as ulnar deficiency, multiple exostoses, and neurofibromatosis. We report a previously unrecognised form, caused by focal cortical indentation. We have treated five children with this condition, three girls and two boys; the mean age at presentation was 5 years (2 to 8). The deformity was first recognised about the age of two years, and progressed gradually. The radiological findings were the same in all cases. The focal cortical indentation was seen at the distal end of the ulna with anteromedial bowing and dysplasia. The radial head was dislocated posterolaterally. In one patient the histological findings at the site of indentation were of a fold of tissue resembling periosteum, which interfered with enchondral ossification. Treatment by ulnar lengthening using an external fixator and osteotomy which corrected both the ulnar deformity and reduced the dislocated radial head in two cases gave the best results.
