The results of some studies done on effect of spinal orthosis on thoracolumbar fracture.

Researcher	Number	Age	Follow-up	Intervention	Procedure	Results
Dai et al.16	16 burst fracture (T12–L2)	No information	3–7 years	Hyper extension body brace	Subjects wore a hyper extension body brace after postural reduction	Canal compromise: 8.5%. None of the subjects was neurologically worse at follow-up.
Denis et al.17	36 (thoracolumbar fracture without neurologic deficit)	No information	42 month	Body cast	The subjects used body cast. Their abilities to return to their job and neurological complications were evaluated in this study.	75% able to return to work. Neurological complications were 17%.
Hitchon et al.18	32 (thoracolumbar fracture)	No information	3–5 months	Thoracolumbar body cast	Frankel score to check neurological compliance. The ability to return to the previous job, and angulation of the vertebra were also evaluated in this study.	Incidence of pain was 42%. Ability to return to previous employment was 60%. Residual canal was 65 ± 18%. Frankel system improved by 0.2 ± 0.4. Angulation was 13.5 ± 8.5
Shen et al.19	47 single level closed burst fracture at T11–L2	18–65	2 years	Hyper extension brace	The patients allowed doing various activities with the brace.	Ability to return to work: 56% Load share score: 4.1 Kyphotic angle worsen by 4 degrees. Low back pain outcome score: 65
Wood et al.20	23 single level burst fracture at thoracolumbar (T10–L2)	No information	44 month	Body cast	The alignment of the spine in sagittal and coronal planes was analyzed by use of radiograph and CT scan.	Kyphotic angle increase: 13% Canal compromise increase: 19% Complication = 2 Less disability
