Introduction: In 1962 Harrington published his method of spinal instrumentation in scoliosis treatment. 256 patients have been treated with this instrumentation at the Hospital for Orthopaedic Surgery Stolzalpe in the years of 1968 –1992.

Material & Methods: A retrospective study was performed on 74 patients (48 female, 26 male) with a mean follow up time of 22,5 years. A clinical examination, x-ray, spirometry was performed as well as the Oswestry Score and the Visual Analogue Scale test (VAS) to determine the patients confidence and possibilities in activities of daily living (ADL), profession and sports. Also the ROM of the spine, degeneration of the adjacent levels and loss of correction were a subject of interest.

Results: All patients were satisfied or very satisfied and there were no severe restrictions in their ADL. 92 % are busy in the normal working process, 61 % do sports without complaints. The mean Oswestry Score was 9 pts (1–12,5) and the average VAS was 1,1 of 10 (0–4), with major problems in sitting and standing. Spirometry was restricted in 33%, movement was limited in side bending in nearly all patients.

Conclusion: Although with Harrington’s method no segmental correction was possible and long time casting and orthetic aids were necessary, we found very confident patients without major restrictions in daily life. Similar long term results with modern methods and instruments have to be proven.
