Abstract:

Objective To investigate the in-brace and short-term correction of 3D-printed scoliosis orthoses.
Methods From July to December 2021, 36 patients with adolescent idiopathic scoliosis from Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were selected to complete full-length radiographs of the spine before and immediately after wearing the orthosis. They wore the orthosis more than 20 hours a day, and took radiographs six months later. Cobb angle was calculated. They were assessed with Chinese version of the Scoliosis Research Society's outcomes instrument 22 (SRS-22) before wearing and six months follow-up.
Results The mean Cobb angle was (22.10±6.29)° before wearing, and it was (7.85±10.90)° immediately after wearing (t = 4.775, P < 0.01) and (14.33±0.74)° six months follow-up (t = 4.189, P < 0.01). The score of functional status of SRS-22 increased six months follow-up (Z = -2.676, P < 0.01). The Cobb angle immediately after wearing correlated with the Cobb angle six months follow-up (r = 0.826, P < 0.05).
Conclusion 3D-printed scoliosis orthoses can correct the scoliosis satisfactorily, in-brace and in short-term.
