Multicenter Study Comparative Study
Incidence, mode, and location of acute proximal junctional failures after surgical treatment of adult spinal deformity.
Multicenter, retrospective series. ⋯ APJFs were identified in 5.6% of patients undergoing surgical treatment of adult spinal deformity, with failures occurring primarily in the TL region of the spine. There is evidence that the mode of failure differs depending on the location of UIV, with TL failures more likely due to fracture and UT failures more likely due to soft-tissue failures.

An association study to comprehensively clarify variations of genetic determinants of peak height velocity (PHV) during puberty in adolescent idiopathic scoliosis (AIS). ⋯ Polymorphisms of the rs4794665 in C17orf67 and rs12459350 in DOT1L were associated with combined predisposition to AIS susceptibility and higher pubertal PHV, which strongly mirrored the anthropometric findings of taller pubertal stature and accelerated growth rate described in AIS.
