Early-onset scoliosis is often effectively managed by serial casting. Properly localizing the apex of the molds with the cast in place is challenging. The authors explored the effectiveness of a novel technique: incorporation of adhesive pads placed over the major curve apex before Mehta casting.
To determine the effect of adhesive pads placed over the apex of scoliosis curves on curve correction 1) after the first cast and 2) after final cast.
The 27 patients who received body casts (2000 through 2013) were divided into 2 groups, those without and with apical adhesive pads (5 to 6 layers of pads placed on the major curve’s apex during casting): non-pad (NP) group (n = 12) and pad (P) group (n = 15), respectively. Groups were compared for percentage of Cobb angle change from the first cast and curve correction to a Cobb angle of less than 25° with Student t and chi-square tests (significance, p value less than .05).
The mean percentage of major first-cast curve correction was 39% ± 18% and 56% ± 17% in the NP and P groups, respectively. Of the 26 patients out of cast, 11 (42%) had a Cobb angle of less than 25°: 3 (25%) and 8 (57%) in the NP and P groups, respectively. The mean differences between the 2 groups in percentage of major curve correction and this Cobb angle correction were significant: p = 0.023 and 0.005, respectively.
Adhesive pads placed over major curve(s) during Mehta casting were effective in increasing the amount of major curve correction from the first cast for idiopathic early-onset scoliosis, and in decreasing curves to less than 25° at final follow up.
