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

Researcher	Number	Age	Follow-up	Intervention	Procedure	Results
Ohana et al.10	33 subjects with type A thoracolumbar fracture (T11–L4).	No information	No information	Subjects ambulate with a lumbar orthosis.	Patients with neurological deficient were excluded. Restriction in body function was measured. Restriction in participation in life was also measured.	90% of the subjects return to their work. 37% of patients were not able to perform dynamic lifting test in normal range. Patients do reasonably well with conservative treatment 5 years after treatment. The results showed that thoracolumbar fractures with compression as much as 30% can be treated with early ambulation with no external support.
Hartman et al.34	32 patients with stable neurological deficit (23 men, 9 women) at T3–L5. (20 burst fracture, 6 fracture dislocation, 5 compression fracture, 1 gunshot)	3.68	22.3 months (12–60)	Molded TLSO	Frankel system was used for assessing neurological deficient. Molded TLSO orthosis was used for 2–3 months. Radiographic X-Ray evaluation was done.	Kyphosis = Progressed by 5.7 degree Average decrease vertebral height= 9.7% 2 complications Use of non-operative treatment can result in low morbidity and excellent outcome. Neurological injury and multitrauma are not always contraindicated to non-operative treatment.
Argenson et al.21	10 patients with thoracic spine fractures (T1–T10). 57% compression fracture, 20% burst fracture, 2.8% flexion distraction and 23% fracture dislocation.	No information	No information	No information	Use of orthosis	Conservative treatment was difficult because of associated parietal lesions. These subjects had only moderate reductions that maintain poorly in time, but had no major painful sequence.
