“…21 Thus, the prediction of spinal height loss or the original body height loss in scoliosis patients has been reported. 1,[22][23][24] Several equations have been proposed in predicting height gain after scoliosis correction as described in Table 5. Watanabe et al (2012) proposed that increase in T1-L5 length (mm) equal to correction of the Cobb angle Â 0.77.…”

Purpose: This study aims to derive a formula to predict post-operative height increment in Lenke 1 and Lenke 2 adolescent idiopathic scoliosis (AIS) patients using preoperative radiological parameters. Methods: This study involved 70 consecutive Lenke 1 and 2 AIS patients who underwent scoliosis correction with alternate-level pedicle screw instrumentation. Preoperative parameters that were measured included main thoracic (MT) Cobb angle, proximal thoracic (PT) Cobb angle, lumbar Cobb angle as well as thoracic kyphosis. Side-bending flexibility (SBF) and fulcrumbending flexibility (FBF) were derived from the measurements. Preoperative height and post-operative height increment was measured by an independent observer using a standardized method.

“…Bjure et al used standing antero-posterior radiographs of 62 patients with scoliosis; however, no information about type of scoliosis or curve magnitude was given. The logarithm of the trunk height loss associated with scoliosis was correlated with the Cobb angle of the primary curve [7]. The presented equation,…”

“…The T1-S1 length of the spine was measured along the curved line starting at the midpoint of the T1 proximal endplate, crossing the centroids of T1-L5 vertebral bodies and reaching the midpoint of the S1 proximal endplate (Fig. 1) [7][8][9][10][11]. The loss of body height was calculated as the difference between the T1-S1 spinal length and the T1-S1 spinal height.…”

“…Corrected body height is needed to establish various clinical parameters such as normal values of blood pressure in children, lungs vital capacity (VC), growth charts, and body mass index (BMI) [1][2][3][4][5][6]. In 1968, Bjure et al [7,8] developed an empirically based formula employing the Cobb angle for predicting proper body height in scoliotic patients. Independently, Kono et al [9], Ylikoski [10] and finally, Stokes [11] presented approaches consisting of regression analysis of the radiological data for calculating the corrected body height in scoliotic patient.…”

Purpose The aim of the study was to analyze four radiographic methods of calculating the loss of body height associated with scoliosis. Methods Thirty patients with right thoracic idiopathic scoliosis were examined with standing postero-anterior radiographs. Cobb angles of the upper thoracic, main thoracic and lumbar curves were measured. The loss of body height due to scoliosis was measured directly on the radiographs and then calculated using the methods of Bjure, Kono, Stokes and Ylikoski, respectively. The reproducibility of calculations was tested. Detailed analysis of two patients with similar Cobb angle but different trunk height was performed. Results The mean Cobb angle of the main thoracic curve was 46°(21°-74°). The mean loss of body height was 23 mm (11-43 mm) calculated by method of Bjure, 7 mm (-24 to 46 mm) by Kono, 20 mm (5-47 mm) by Stokes, 14 mm (3-36 mm) by Ylikoski, versus 18 mm (3-50 mm) measured directly on radiographs. The overall difference between the loss of body heights was significant (p \ 0.0001), with significant differences in pairs for: Bjure versus Kono (p \ 0.0001), Stokes versus Kono (p = 0.0002), Kono versus measured (p = 0.0061) and Bjure versus Ylikoski (p = 0.0386). Strong linear correlation between the methods was found (r C 0.92; p \ 0.0001). High reproducibility of height loss calculations was noticed. The two patients with similar Cobb angle and different trunk height revealed similar height loss calculated, while different loss measured on radiographs. Conclusions There existed no overall agreement between the four methods of calculation of the loss of body height associated with scoliosis. Calculations based on the Cobb angle produced inaccuracy and could be supplemented with data considering trunk size.
