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.

In vivo studies of the vascular system in ossification of the posterior longitudinal ligament (OPLL) model mice. ⋯ Ossification model mice had impaired blood coagulation and vascular morphology and high capacity for vasculogenesis. With regard to the pathogenesis of VTE, ttw mice harbor an environment that promotes the development of VTE.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.

A retrospective, radiographic comparative study conducted in a single academic institution. ⋯ Fulcrum extension, compared to conventional extension, is better at generating lordosis in the lower lumbar spine, thus improving preoperative assessment of stiffness or instability of the lumbar spine. Both extension methods were equally effective at determining the patient-specific maximum HL to assess the flexibility and compensation occurring at the hip, potentially guiding surgical management of patients with degenerative spines.Level of Evidence: 3.
