AIM: To determine whether trunk deformity correction is stable over time. MATERIALS AND METHODS: Thirty-seven patients (5M, 32 F) average age 16 years, 3 months (range, 10 to 38) met inclusion crieteria of primary posterios instrumentation (ISOLA) and arthrodesis with x-ray and surface topography measurements [Posterior Trunk Symmetry Index (POTSI)] and [Suzuki Hump Sum (SHS)] pre-operatively and at 2 years follow up. For 30 patients measurements were also available post-operatively. Patient's average pre, post, and two-year measurements were: Largst Cobb 65 degrees (+/- 12), 21 degrees (+/- 8), and 21 degrees (+/- 17); POTSI 53 (+/- 29), 28 (+/- 12); and 22 degrees (+/- 10); and SHS 18 (+/- 11), 12 (+/- 7), and 12 (+/- 7), and 12 (+/- 6). Statistical analysis was done with the sign test, comparing only patients with data at the intervals studied. Surface topography measurements were considered to be unchanged/tied unless they increased or decreased by more than 8 for POTSI and 3.5 for SHS, Significance was set at p<0.05. RESULTS: POTSI changes were pre-to post operative: 20 improved (I), 3 worsened (W), and 7 tied (T) (p<0.01): pre to two years: 30 (I), 4 (W), and 3 (T) (p<0.01): and from post to two years: 14 (I), 3 (W) and 13 (T) (p<0.01). SHS changes were pre to post to two years: 18 (I), 2 (W), and 11 (T) (p<0.01); pre to two years: 23 (I), 2 (W), and 11 (T) (p<0.01); ad post to two years: 4(I), 6 (W), and 20 T (ns). CONCLUSION: Trunk deformity improvement following surgery is stable or improved over time with surgical techniques utilized.
