Annual and intra-annual climate variability and change of the Volta Delta, Ghana.

Deltas are geographically and socio-ecologically distinct systems, with a unique climate and contextually high vulnerabilities to climate dynamics. Hence, they require specific climate change adaptation and policy responses, informed by delta-scale analysis. However, available climate knowledge on deltas is based mainly on broad-scale analysis that masks information unique to deltas.

Characterization of complex vertebral transposition (gamma deformity) > 180 degrees: clinical and radiographic outcomes of halo gravity traction and vertebral column resection (VCR).

Study Design: Prospective case series OBJECTIVE: Results of surgical treatment of complex vertebral transposition "Gamma Deformity" > 180 degrees with halo gravity traction (HGT) and vertebral column resection (VCR). We recently published a novel classification system for complex spine deformities of which complex vertebral transposition > 180 degrees (Gamma; type 3) was described. Halo gravity traction (HGT) has been shown to mitigate surgical risk in complex spine deformity correction and in some cases obviates the need for three-column osteotomy.

Erratum to Surgical Risk Stratification Based on Preoperative Risk Factors in Severe Pediatric Spinal Deformity Surgery [Spine Deformity 2 (2014) 340-349].

The corresponding author regret that co-author name was incorrectly published as "Elias C. Papadopoulus" in the article. The correct name of the author should be displayed as "Elias C.

Investigating the Universality of Preoperative Health-Related Quality of Life (HRQoL) for Surgically Treated Spinal Deformity in Young Adults: A Propensity Score-Matched Comparison Between African and US Populations.

Study Design: Retrospective analysis of propensity score-matched (PSM) observational cohorts.

Objectives: To evaluate and compare preoperative health-related quality of life (HRQoL) scores and radiographic measurements of young African and US adults with spinal deformity (ASD).

Summary Of Background Data: Young ASD patients in the United States are motivated more to correct coronal and sagittal plane deformities than to alleviate pain.

Apex of deformity for three-column osteotomy. Does it matter in the occurrence of complications?

Background: Posterior vertebral column resection (PVCR) is a challenging but effective technique for the correction of complex spinal deformity. However, it has a high complication rate and carries a substantial risk for neurologic injury.

Purpose: The aim was to test whether the apex of the deformity influences the clinical outcomes and complications in patients undergoing PVCR.

Surgical Risk Stratification Based on Preoperative Risk Factors in Severe Pediatric Spinal Deformity Surgery.

Study Design: Retrospective review.

Objective: The purpose of this study is to review the postoperative complications in pediatric patients undergoing spine surgery and to establish a preoperative classification that stratifies surgical risk and case difficulty.

Summary Of Background Data: Pediatric spinal deformity (PSD) surgery can be challenging technically as well as economically.
