Background: Recent studies highlight the increasing adoption of single-position prone lateral(SP-PL) and single-position lateral decubitus(SP-LD) in Minimally Invasive Spine Surgery(MISS) to reduce operative time, enhance patient safety, and improve surgical accessibility.
Objective: To assess the differences between SP-PL and SP-LD achievement of optimal postoperative outcomes and post-operative complication rates.
Study Design: Retrospective review of prospectively collected MIS database.
Introduction: Various techniques have been described for restoring leg length and offset during total hip arthroplasty (THA). We herein describe a novel "Quartered Head Technique" (QHT) involving a series of femoral osteotomies.
Methods: 124 hips were included in the analysis.
Background And Objectives: The spectrum of patients requiring adult spinal deformity (ASD) surgery is highly variable in baseline (BL) risk such as age, frailty, and deformity severity. Although improvements have been realized in ASD surgery over the past decade, it is unknown whether these carry over to high-risk patients. We aim to determine temporal differences in outcomes at 2 years after ASD surgery in patients stratified by BL risk.

Methods: Adult spinal deformity (ASD) patients with baseline and perioperative (by 6 weeks) data were stratified based on single-stage (same-day) or multistage (staged) surgery, excluding planned multiple hospitalizations. Means comparison analyses were used to assess baseline demographic, radiographic, and surgical differences between cohorts.
Study Design: Retrospective cohort study of a prospectively collected single-center database.
Objective: Distal Junctional Kyphosis (DJK) is one of the most common complications in adult cervical deformity (ACD) correction. The utility of radiographic alignment alone in predicting and minimizing DJK occurrence warrants further study.
Unlabelled: BACKGROUND : The use of bone morphogenic protein (BMP-2) in adult spine deformity (ASD) surgery remains controversial more than two decades following its approval for clinical application in spine surgery. This study was performed to assess outcomes in patients undergoing ASD surgery with BMP application compared with a combination of bone marrow aspirate, cancellous bone chips and i-Factor.
Methods: This was a retrospective cohort study.
Purpose: To investigate the impact of the Global Alignment and Proportion (GAP) score components on patient outcomes in Adult Spine Deformity (ASD) surgery.
Methods: Patients included underwent assessment via the GAP score and its individual components: pelvic version (GAP PV), lumbar lordosis (GAP LL), lumbar distribution index (GAP LDI) and spinopelvic component (GAP SP). Multivariable analyses assessed the association between alignment in these components and clinical outcomes in ASD patients.

Aims: The aim of the study was to assess preoperative radiographic parameters predictive of cervical deformity (CD) autocorrection in patients undergoing thoracolumbar deformity (ASD) surgery.
Study Design/setting: This was a retrospective cohort study.
Methods: Inclusion criteria were operative ASD patients with complete baseline (BL) and 2-year radiographic data.
Aims: The aim of this study was to investigate the impact of the level of upper instrumented vertebra (UIV) in frail patients undergoing surgery for adult spine deformity (ASD).
Methods: Patients with adult spinal deformity who had undergone T9-to-pelvis fusion were stratified using the ASD-Modified Frailty Index into not frail, frail, and severely frail categories. ASD was defined as at least one of: scoliosis ≥ 20°, sagittal vertical axis (SVA) ≥ 5 cm, or pelvic tilt ≥ 25°.
Background: To compare degrees of cSVA correction and to theorize possible minimum and maximum thresholds of cSVA correction for patients to benefit clinically.
Methods: 657 operative ACD patients in a retrospective cohort study of a prospectively enrolled database with complete baseline and two year radiographic and HRQL data were examined. Patients were grouped into an optimally corrected cohort (OC; postop cSVA ≤ 4 cm) and an undercorrected cohort (UC; postop cSVA > 4 cm) based on postoperative radiographs.
Study Design: Retrospective cohort study.
Purpose: To determine the incidence and success of three-column osteotomies (3COs) performed in primary and revision adult spine deformity (ASD) corrective surgeries.
Overview Of Literature: 3COs are often required to correct severe, rigid ASD presentations.
Objective: The purpose of this study was to assess how various realignment strategies affect mechanical failure and clinical outcomes in pelvic incidence (PI)-stratified cohorts following adult spinal deformity (ASD) surgery.
Methods: Median and interquartile range statistics were calculated for demographics and surgical details. Further statistical analysis was used to define subsets within PI generating significantly different rates of mechanical failure.
Purpose: While existing adult spinal deformity (ASD) alignment schemas acknowledge the dynamic relationship between the pelvis and spine, consideration of vertebral pelvic angles (VPA) thresholds for PJK may provide further insight into the relationship of each individual vertebra to the pelvis, which may allow for greater individualization of operative targets. Herein, we examine VPA's utility in preventing mechanical complications and its possible unification with prevalent scoring systems.
Methods: In a retrospective cohort study of a prospectively collected database, operative ASD patients ≥ 18 years with complete baseline (BL) and two-year (Y) operative, radiographic, and health-related quality of life data were included.
Objective: The objective was to evaluate factors associated with the long-term durability of outcomes in adult spinal deformity (ASD) patients.
Methods: Operative ASD patients fused from at least L1 to the sacrum with baseline (BL) to 5-year (5Y) follow-up were included. Substantial clinical benefit (SCB) in Oswestry Disability Index (ODI), numeric rating scale (NRS)-back, NRS-leg, and Scoliosis Research Society (SRS)-22r scores and physical component score were assessed on the basis of previously published values.
Background: Recombinant human bone morphogenetic protein-2 (rhBMP-2) has not shown superior benefit overall in cost-effectiveness during adult spinal deformity (ASD) surgery.
Study Design/setting: Retrospective PURPOSE: Generate a risk score for pseudarthrosis to inform the utilization of rhBMP-2, balancing costs against quality of life and complications.
Methods: ASD patients with 3-year data were included.
Purpose: To assess impact of baseline disability on HRQL outcomes.
Methods: CD patients with baseline (BL) and 2 year (2Y) data included, and ranked into quartiles by baseline NDI, from lowest/best score (Q1) to highest/worst score (Q4). Means comparison tests analyzed differences between quartiles.
Adult spinal deformity (ASD) patients with concurrent sacroiliac joint (SIJ) pain are susceptible to worse postoperative outcomes. There is scarce literature on the impact of ASD realignment surgery on SIJ pain. : Patients undergoing ASD realignment surgery were included and stratified by the presence of SIJ pain at the baseline (SIJP+) or SIJ pain absence (SIJP-).

Patients sustaining such complications may demonstrate worse recovery profiles compared to their unaffected peers. DJK was defined as a >10° change in kyphosis between LIV and LIV-2, and a >10° index angle.

Objectives: To assess the impact of Enhanced recovery after surgery (ERAS) protocols on peri-operative course in adult cervical deformity (ACD) corrective surgery.
Methods: Patients ≥18 yrs with complete pre-(BL) and up to 2-year (2Y) radiographic and clinical outcome data were stratified by enrollment in an ERAS protocol that commenced in 2020.
Background: With the increasing amount of elective spine fusion patients presenting with cardiac disease and congestive heart failure, it is becoming difficult to assess when it is safe to proceed with surgery. Assessing the severity of heart failure (HF) through ejection fraction may provide insight into patients' short- and long-term risks.
Purpose: The purpose of this study was to assess the severity of HF on perioperative outcomes of spine fusion surgery patients.
