Purpose Adult spinal deformity (ASD) surgery gives good clinical outcomes but has a high
rate of mechanical complications (MC). In 2016, Lafage described the age-adjusted …

Proximal junction kyphosis (PJK) is a common imaging finding after long-level fusion, and
proximal junctional failure (PJF) is an aggravated form of the progressive disease spectrum …

Purpose. Despite adequate correction, the pelvis may fail to readjust, deemed pelvic
nonresponse (PNR). To assess alignment outcomes [PNR, proximal junctional kyphosis …

Objective To evaluate the mid-to long-term clinical outcomes of circumferential minimally
invasive surgery (CMIS) without posterior column osteotomies for severe adult spine …

Spinal alignment is essential to a well-functioning musculoskeletal system. Normal standing
orientation as defined by Dubousset 1 is with the skull positioned roughly over the femoral …

This review focuses on the surgical techniques that are used to effectively correct
thoracolumbar adult spinal deformity. Preoperative considerations and planning for …

OBJECTIVE The objective of this study was to adjust the sagittal age-adjusted score (SAAS)
to accommodate frailty in alignment considerations and thereby increase the predictability of …

Adult spinal deformity causes pain, disability, and alterations in the quality of life of patients.
Sagittal alignment and spinopelvic parameters have been established to provide surgeons …

Background The present study assumed that the effects of deformity correction amounts on
proximal junctional kyphosis (PJK) development after long deformity surgery would vary …

Study Design. Retrospective analysis of prospectively collected data. Objective. Evaluate the
impact of correcting to normative segmental lordosis values on post-operative outcomes …
