A prospective cohort study. ⋯ This study demonstrates that fear avoidance and demoralization directly correlate with worsening gait and balance. Furthermore, patients with TSK > 41 and DS > 30 have more underlying psychological factors that contribute to significantly worse function compared with lower scoring peers. Understanding this relationship and using these guidelines can help identify and treat patients whose gait dysfunction may be amplified by psychologic distress.Level of Evidence: 3.

A retrospective study of the prospective cohort. ⋯ The present study demonstrated the accurate distribution of the severity of scoliosis and identified the predictive factors for progression of scoliosis in patients with Marfan syndrome.Level of Evidence: 3.

An in vivo model to study the effect of an injectable hyaluronic acid (HA) hydrogel following puncture-induced lumbar disc injury in rabbits. ⋯ An injectable HA hydrogel had the protective effects in suppressing the loss of disc height, promoting tissue hydration for structural repair, and attenuating inflammation and innervation to prevent further disc degeneration.Level of Evidence: N/A.

Predictors of Falls in Patients with Degenerative Cervical Myelopathy: A Prospective Multi-Institutional Study.
Prospective multicenter study. ⋯ We identified preoperative lower serum potassium level and weaker handgrip strength as significant predictors of falls in patients with DCM. Therefore, DCM patients with these risk factors should be cautious about falls and might be candidates for immediate surgical intervention.Level of Evidence: 3.
