Survey study. ⋯ More than 90% of spine specialists still use orthosis in conservative treatment of adult patients with acute TL fractures. Orthosis cost vary significantly between continents, and it is influenced by the country's economy.Level of Evidence: 4.
-
Experimental animal study. ⋯ We demonstrated that long-term mechanical stress caused LF hypertrophy with progressive elastic fiber disruption and cartilage matrix production accompanied by enhanced myofibroblasts. In addition, the reported rabbit model could be extended to elucidate the mechanism of LF hypertrophy and to develop new therapeutic strategies for LSS by preventing LF hypertrophy.Level of Evidence: SSSSS.

Cross-sectional study. ⋯ Both AA and AW are associated with adverse outcomes in patients undergoing spinal fusion surgery with more pronounced risks for AW. Aggressive management in perioperative period is required to improve outcomes in these patients.Level of Evidence: 3.
