Temporal Evolution and Stationary Point Mechanisms of Pelvic Characteristic Angles Throughout the Sit‐to‐Stand Cycle

Orthopaedic Surgery, Volume 18, Issue 8, Page 1688-1699, August 2026.
Dynamic motion‐capture and musculoskeletal simulation of stand‐to‐sit reveal nonlinear pelvic kinematics in healthy subjects. Pelvic tilt and sacral slope show synchronized mid‐cycle turning points, strongly linked to center‐of‐gravity transitions. These dynamic features, absent in static radiographs, may refine functional acetabular safe zones to ...

Measurement of Spinopelvic Parameters on Standing Lateral Lumbar Radiographs

, 2017
STUDY DESIGN: This was a radiographic validity and reliability study. OBJECTIVE: We assessed the validity and reliability of measurements made on standing lateral lumbar radiographs, compared with lateral whole-spine radiographs, for evaluating ...

Locally Aggressive Desmoid Tumor With L4–L5 Vertebral Invasion and Progressive Neurological Deficit: A Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Desmoid‐type fibromatosis is a rare, non‐metastatic fibroblastic neoplasm that may cause major morbidity through locally infiltrative growth. Spinal involvement with vertebral destruction and neurological deficit is particularly uncommon and may mimic malignant spindle‐cell or primary osseous tumors.

Prevalence of Cam Femoroacetabular Lesions in Medieval (1200‐1600 CE) and Postmedieval (1600‐1850 CE) Dutch Skeletal Collections

Arthroscopy, Sports Medicine, and Rehabilitation, Volume 8, Issue 3, June 2026.
Purpose To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the

The rib cage: a new element in the spinopelvic chain [PDF]

, 2022
Introduction: This study analyzes anatomical variations of the thoracic cage (TC) according to spinopelvic alignment, age and gender using stereoradiography in erect position. Methods: This retrospective multicentric study analyzed computed parameters

Increased Cup Anteversion May Not Prevent Posterior Dislocation in Patients With Abnormal Spinopelvic Characteristics in Total Hip Arthroplasty

Arthroplasty Today, 2023
Background: The aims of this study were to (1) assess the degree of variation in acetabular component placement and combined anteversion in a large cohort of dislocating total hip arthroplasties; (2) assess the spinopelvic characteristics of the cohort ...

What Are the Optimal Sagittal Alignments in Primary Total Knee Arthroplasty: A Systematic Review and Meta‐Analysis

Orthopaedic Surgery, Volume 18, Issue 6, Page 1155-1172, June 2026.
The optimal sagittal alignment targets for TKA remain uncertain; however, favorable sagittal alignments are hypothesized to improve prognosis and function. Discussions on sagittal alignments emphasize biomechanical, anatomical, and soft tissue‐friendly approaches to surgery.

Implications of Spinopelvic Alignment for the Spine Surgeon

, 2011
The relation of the pelvis to the spine has previously been overlooked as a contributor to sagittal balance. However, it is now recognized that spinopelvic alignment is important to maintain an energy-efficient posture in normal and disease states.

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
