In the previous paper (part I), a new approach which makes it possible to evaluate the rotational deformity of scoliosis both qualitatively and quantitatively was proposed and named Laser Torsography. In the present paper this new method is applied to observation of clinical courses of scoliotic patients in order to demonstrate changeability of the rotational deformity during treatment. Thirty-five idiopathic scoliotic patients were treated conservatively (5 cases: observation only, 30 cases: brace treatment) and effects of the treatment were evaluated by means of roentgenographic examination (Cobb method) and Laser Torsography at average intervals of 15 months and the attitude of the rotation deformity was compared with that of the lateral flexion deformity. The results show that in more than half of the cases the prognosis of the rotation deformity differed from the lateral flexion deformity. Consequently the importance of measuring the rotation deformity separately should be emphasized. Seventeen scoliotic patients were treated surgically and correctability of the rotation deformity was assessed by comparing preoperative and postoperative Laser Torsography. Out of them there are 10 cases on which Harrington instrumentation with DTT were performed. The effects of this procedure on rotation were as follows: little improvement or adverse effect in 6 cases, moderate improvement in 3 cases and remarkable improvement in one case. It is expected from this investigation that Laser Torsography will play an important role in the therapeutic occasion of scoliosis as an indispensable diagnostic tool for the estimation of the rotational deformity.

Radiographic outcome and complications of Harrington-DTT (H) and Cotrel-Dubousset (CD) instrumentation of idiopathic adolescent thoracic scoliosis were compared retrospectively. The patient material consists of 55 consecutive patients in the H group and 52 consecutive patients in the CD group. The mean age at operation was 15 +/- 2 years (range, 11-19 years) in both groups. The follow-up interval was 43 +/- 18 months (range, 17-91 months) in the H group and 28 +/- 11 months (range, ten to 53 months) in the CD group (p = 0.0001). The preoperative radiographic measurements (Cobb angle of primary and secondary curve, apical rotation, thoracic kyphosis, lumbar lordosis) were fully comparable in both groups. The mean correction of the primary curve at the follow-up evaluation was 47% in both groups. Apical rotation of the primary curve remained almost unchanged in both groups. Rotation of the secondary curve increased significantly in the CD group. Thoracic kyphosis was unchanged in the CD group but decreased in the H group. Spinal balance worsened in 29% of the H cases and in 44% of the CD cases. There were no neurologic complications in either of the groups. Intraoperative lamina fractures (four cases) and postoperative hook dislodgement (five cases) occurred only in the CD group. One distraction rod breakage occurred in the H group. Three reoperations were performed in the H group, nine in the CD group.

We reviewed the clinical charts and roentgenogram of 111 patients operated with Harrington-DTT instrumentation for idiopathic adolescent scoliosis at Copenhagen University Hospital from 1983 to 1989. Male/female ratio was 1:9. Median age was 14.5 (11-21) years at the time of surgery. Median follow-up time was 4.0 (1-7) years. Of the 111 patients, complications were registered in fifteen. Seven were reoperated, four due to gliding of the upper hook, three due to fatigue fracture of the Harrington rod before union. We found no deep infections or persisting neurological damage.
