Combine Short‐Segment Fixation and Leverage Reduction Technique to Correct Kyphotic Angle in Kümmell's Disease

Orthopaedic Surgery, Volume 18, Issue 7, Page 1518-1528, July 2026.
This study introduces a leverage reduction technique with short‐segment fixation for Kümmell's disease and kyphosis deformity. This advanced approach reliably restores vertebral height, corrects kyphosis, and improves clinical outcomes. ABSTRACT Objective Kümmell disease is a prevalent spinal condition characterized by vertebral fractures and ...

Generalized Joint Hypermobility in Adolescent Idiopathic Scoliosis: Greater Curve Flexibility, Larger Thoracic Kyphosis, but Higher Complication Risk

Orthopaedic Surgery, Volume 18, Issue 7, Page 1414-1425, July 2026.
Generalized joint hypermobility in adolescent idiopathic scoliosis is linked to greater spinal flexibility and increased thoracic kyphosis, but also elevates the risk of surgical complications, despite no significant differences in patient‐reported outcomes.

Distal Adding‐On After Selective Thoracolumbar/Lumbar Fusion for Lenke 5C AIS: The Role of Proximal Coronal Construct Position and Postoperative UIV Translation

Orthopaedic Surgery, Volume 18, Issue 6, Page 1191-1202, June 2026.
In 74 Lenke 5C AIS patients undergoing selective thoracolumbar/lumbar fusion, distal adding‐on occurred in 18 (24%) at ≥ 2‐year follow‐up. Multivariable analysis identified postoperative upper instrumented vertebra translation as an independent factor associated with adding‐on, highlighting the importance of construct‐level coronal alignment beyond LIV

Optimizing Surgical Strategies for Preventing Proximal Junctional Complications: A Systematic Review and Meta-analysis of Operative Techniques in Adult Spinal Deformity [PDF]

Neurospine
Objective Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) are common complications following long-segment spinal fusion, particularly in adult spinal deformity (ASD) correction surgery.

CT based bone mineral density as a predictor of proximal junctional fractures

North American Spine Society Journal, 2022
Background: Proximal junctional fractures (PJFr) can be a catastrophic complication associated with adult spinal deformity surgery. Osteoporosis can be a major risk factor for the cause of PJFr. Recent studies suggest using surrogate computed tomography (

Comparing the Prognostic Utility of Vertebral and Endplate Bone Quality Scores for Cage Subsidence Following Single‐Level Anterior Cervical Discectomy and Fusion: A Retrospective Analysis

Orthopaedic Surgery, Volume 18, Issue 3, Page 489-499, March 2026.
MRI‐derived bone quality metrics are reliable predictors of cage subsidence following ACDF. Their implementation may be used to guide surgical planning and improve outcomes. ABSTRACT Objective Cage subsidence following anterior cervical discectomy and fusion (ACDF) is linked with poor bone quality.

Risk Factors for Proximal Junctional Fracture Following Fusion Surgery for Osteoporotic Vertebral Collapse with Delayed Neurological Deficits: A Retrospective Cohort Study of 403 Patients

Spine Surgery and Related Research, 2019
Introduction: Approximately 3% of osteoporotic vertebral fractures develop osteoporotic vertebral collapse (OVC) with neurological deficits, and such patients are recommended to be treated surgically.

Ligament augmentation for prevention of proximal junctional kyphosis and proximal junctional failure in adult spinal deformity [PDF]

Journal of Neurosurgery: Spine, 2018
OBJECTIVEProximal junctional kyphosis (PJK) is a well-recognized, yet incompletely defined, complication of adult spinal deformity surgery. There is no standardized definition for PJK, but most studies describe PJK as an increase in the proximal junctional angle (PJA) of greater than 10°–20°.

A feasibility study of functional preservation in craniospinal irradiation with photon for pediatric medulloblastoma

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Craniospinal irradiation (CSI) is essential for treating pediatric medulloblastoma (MB) but causes significant long‐term toxicities. Existing dose‐reduction or partial‐sparing strategies improve neurocognitive outcomes but may compromise survival or fail to address other late effects.
