Comparison of clinical and radiological outcomes of three-column lumbar osteotomies with and without interbody cages for adult spinal deformity.
Spine J
January 2025
International Spine Study Group Foundation, Denver, CO, USA.
Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Article Synopsis
- Arterial ischemic stroke (AIS) in children, especially those with childhood leukemia, is a rare but serious condition that can lead to long-term disabilities, with a lack of established guidelines for treating it in pediatric patients.
- A case of a 13-year-old girl with acute lymphoblastic leukemia highlights successful mechanical thrombectomy using advanced devices, which allowed for effective recanalization of affected arteries.
- Despite emerging evidence supporting mechanical thrombectomy for children with AIS, definitive guidelines are still lacking, emphasizing the need for urgent, specialized care by a multidisciplinary team for optimal patient outcomes.*
Effects of phytase and 25-Hydroxycholecalciferol supplementation in broilers fed calcium-phosphorous deficient diets, with or without challenge, on growth performance, body composition, bone development, and gut health.

Article Synopsis
- Flatback deformity, or lumbar hypolordosis, leads to back pain and limits function, and this study examined methods to correct it using spinal surgery techniques on human specimens.
- The research compared two groups: degenerative flatback specimens, which had less lordosis, and iatrogenic specimens, created through surgical procedures, measuring their spinal alignment after various surgical corrections.
- Results showed that for degenerative specimens, surgeries improved spinal alignment, while the iatrogenic group experienced a decline in alignment after initial surgeries, but overall alignment did not differ significantly after further corrective procedures.
Radiographic outcomes and complications of anterior column realignment (ACR): a systematic review.

San Diego Spine Foundation, San Diego CA, USA; Department of Orthopaedic Surgery, University of California, San Diego, CA, USA. Electronic address:
Background: Anterior Column Realignment (ACR) was introduced to serve as a powerful segmental kyphosis correction technique in minimally invasive Adult Spinal Deformity (ASD) surgery. Releasing the Anterior Longitudinal Ligament (ALL) and annulus allows opening of the disc space to accommodate hyperlordotic cages. The overall safety and efficacy of ACR has been difficult to determine due to the heterogenicity of surgical techniques, complications reporting, and a paucity of published studies leading to preliminary and controversial conclusions.
