Lumbar lordosis of extinct hominins

American Journal of Physical Anthropology, 2011
AbstractThe lordotic curvature of the lumbar spine (lumbar lordosis) in humans is a critical component in the ability to achieve upright posture and bipedal gait. Only general estimates of the lordotic angle (LA) of extinct hominins are currently available, most of which are based on the wedging of the vertebral bodies.

First Complete Morphological Description of Schistosoma Reflexum in a Llama

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
ABSTRACT Schistosoma reflexum (SR) is a lethal congenital malformation characterized by severe spinal retroflexion, thoracoabdominoschisis with visceral exposure. This case report aims to describe the morphology and pathology of SR in a llama. A white male llama (Lama glama) cria was delivered with dystocia following a normal gestation.

Modified Freehand Minimally Invasive Transforaminal Lumbar Interbody Fusion for Single‐Level Degenerative Lumbar Disease: 3‐Year Multicenter Retrospective Outcomes

Orthopaedic Surgery, Volume 18, Issue 5, Page 932-943, May 2026.
Modified MIS‐TLIF, utilizing a “pedicle‐to‐pedicle” mini‐incision, freehand pedicle screw placement, and expandable tubular decompression, outperformed traditional MIS‐TLIF in single‐level lumbar degeneration by reducing operative time, blood loss, radiation exposure, and complications, while preserving paravertebral muscle function and achieving ...

Risk Factors and Clinical Significance for Retrolisthesis of Adjacent Segment After Transforaminal Lumbar Interbody Fusion

Orthopaedic Surgery, Volume 18, Issue 5, Page 958-966, May 2026.
Preoperative degeneration of endplates, facet joints, and paraspinal muscles, along with intraoperative facet violation, are key predictors of retrolisthesis after TLIF, leading to worse pain and functional outcomes. ABSTRACT Objective Adjacent segment retrolisthesis is a common yet frequently overlooked complication after lumbar fusion, which may lead
