Operative Therapie der idiopathischen Skoliose mittels ventraler Doppelstabinstrumentation

Background

In the surgical treatment of idiopathic scoliosis both anterior and posterior correction and instrumentation techniques are available. The aim of the present study was to analyse the results of a new anterior dual rod instrumentation.

Patients and methods

Prospective analysis of radiometric and clinical parameters of 93 patients operated on between 1996 and 2004 using the Münster Anterior Dual Rod System.

Results

The average curve correction was 65% (fusion length usually Cobb levels) with a preoperative Cobb angle of 59°. Postoperative loss of correction amounted to 1.5° (average follow-up of 36 months). Apical vertebral derotation averaged 45% in the thoracic and 53% in the lumbar spine with a subsequent correction of the rib hump of 66% and the lumbar hump of 81%. There were no revisions or neurological complications.

Conclusion

Anterior dual rod instrumentation enables an effective and safe three-dimensional curve correction in single structural curves with only minimal loss of correction.
