SummaryThe authors present the results of 20 corrective procedures for juvenile cyphosis using Harrington, compressive rods and Hibbs spondylodesis. 16 procedures date back more than one year (average 3 years, 4 months). 10 cases of pure dorsal cyphosis are compared to 10 cases of dorso-lumbar cyphosis. The pre-operative Cobb-angles for cyphosis averaged 52°, postoperatively an average of 24° was measured. This reflects a 57 p. c. average immediate correction (41 p. c. for pure dorsal cyphosis, 71 p. c. for dorso-lumbar cyphosis) following surgery nearly all cases showed a significant loss of correction (average 43 p. c., dorsal 37 p. c., dorso-lumbar 49 p. c.). Three main reasons for this loss of correction are discussed and documented in detail.1.Mal-centered and too short a length of spondylodesis;2.insufficient corrective growth of wedge shaped vertebral bodies post surgery and3.frequent lumbar decompensation into total round back deformity of the pure thoracic spondylodesis. The following changes in procedure to solve the problem of loss of correction are proposed.1.Combined posterior and anterior fusions and2.upper lumbar dorsal fusion together with extended thoracic spondylodesis. The changing indication is discussed. The main but not fatal complication was postoperative wound infection (15 p. c.).ZusammenfassungEs wird über die Ergebnisse von 20 dorsalen Kyphoseaufrichtungsoperationen mit dem Harrington-Kompressorium berichtet. 16 Operationen lagen länger als ein Jahr zurück (Durchschnitt 3 Jahre, 4 Monate). 10 Dorsalkyphosen wurden 10 dorsolumbalen Kyphosen gegenübergestellt. Bei durchschnittlich präoperativen Winkeln von 52 Grad nach Cobb (83–20 Grad) wurden postop. im Schnitt 24 Grad gemessen. Dies entspricht einer 57%igen Korrektur des Kyphosewinkels (41% für Dorsalkyphosen, 71% für dorsolumbale Kyphosen). Im Laufe der Jahre danach trat jedoch in fast allen Fällen ein deutlicher Korrekturverlust von durchschnittlich 43% auf (dorsal 37%, dorsolumbal 49%). Es wurden vor allem 3 Ursachen für die starken Korrekturverluste herausgearbeitet:1.Fehlzentrierte und zu kurze Spondylodesen,2.ungenügendes Keilwirbelwachstum nach der Aufrichtung,3.lumbale Dekompensationen nach thorakaler Spondylodese. Als Formungsmöglichkeiten bieten sich kombimerte dorsale und ventrale Eingriffe Bowie in den oberen Lumbalbereich ausgedehnte dorsale Spondylodesen an. Die Differentialindikation wird herausgearbeitet. Als Hauptkomplikation erwies sich die Infektion (15%).The authors present the results of 20 corrective procedures for juvenile cyphosis using Harrington compressive rods and Hibbs spondylodesis. 16 procedures date back more than one year (average 3 years, 4 months). 10 cases of pure dorsal cyphosis.
