XXX. On the influence of the ocean on the plumb-line in India [PDF]
Philosophical TransactionsAbstract 1. The present paper is a sequel to two former communications to the Society on the effect of Mountain Attraction on the Plumb-line in India. In the first of these (communicated in 1855) the deflection of the plumb-line caused by the Mountain Mass north of Hindostan is calculated; and in the second (forwarded during the ...

Impact of Sagittal Reference Lines on Predicting Distal Junctional Kyphosis in Adolescent Idiopathic Scoliosis [PDF]
Orthopaedic SurgeryObjective Incorporating the sagittal stable vertebra (SSV) in posterior spinal fusion (PSF) may reduce postoperative distal junctional kyphosis (DJK) in adolescent idiopathic scoliosis (AIS), but its determination varies across reference methods and may ...

Impact of spino-pelvic and global spinal alignment on the risk of osteoporotic vertebral collapse
Spine Surgery and Related Research, 2018 Introduction: Numerous studies have reported the risk factors of osteoporotic vertebral collapse. However, whether spino-pelvic and global spinal alignments are associated with the occurrence of osteoporotic vertebral collapse remains unclear. This study
