Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Changes in the Pterygopalatine and Midpalatal Sutures After Rapid Palatal Expansion With Tooth‐Bone‐Borne (MARPE) and Tooth‐Borne (Hyrax) Appliances

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This retrospective cohort study aimed to compare the effects of tooth‐bone‐borne mini‐implant‐assisted rapid palatal expansion (MARPE) and tooth‐borne (Hyrax) rapid palatal expansion (RPE) techniques on the pterygopalatine suture (PPS) and the opening pattern of the midpalatal suture (MPS).

Experimental Analysis of the Stiffest Axis in the Human Cervical Spine

open access: yes, 1992
Clinically, injury to the mid and lower cervical spine occurs frequently as the result of flexion and compression-flexion movement. The mechanisms that cause these injuries and duplication of them, has been the focus of many laboratory experiments ...

Evaluation of Autoregressive Models for Predicting Two‐Dimensional Mandibular Landmark Displacement During Pubertal Growth

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To predict mandibular landmark displacement during pubertal growth using autoregressive models. Materials and Methods The study included 225 subjects with complete cephalometric radiographs from ages 10 to 18. Data were split by subject into training (180; 83 males, 97 females) and test sets (45; 21 males, 24 females).

Cervical Spine Trauma

open access: yes, 2019
Cervical trauma is a serious condition, that may cause permanent disability or even death. Cervical trauma occurs in 2-7% of blunt trauma patients. In Europe, the incidence of cervical trauma is approximately 9-17/100,000 annually,.

The Cervical Vertebral Bone Quality Score Is a Novel Reliable Index Reflecting the Condition of Paraspinal Muscles and Predicting Loss of Cervical Lordosis After Open‐Door Laminoplasty

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1406-1417, May 2025.
There is a close correlation between C‐VBQ scores and the cervical deep extensors, deep flexors, and overall paraspinal muscles relative cross‐sectional area (RCSA) and degree of fat infiltration (DFF). The C‐VBQ score is a comprehensive parameter reflecting the quality of cervical bone and paraspinal muscles.

Endoscopic‐Assisted Posterior Atlantoaxial Fusion: Technical Innovation and Clinical Experience

open access: yesOrthopaedic Surgery, EarlyView.
Endoscopic‐assisted posterior atlantoaxial lateral mass fusion is introduced as a novel minimally invasive technique for treating atlantoaxial instability. The approach enables direct visualization, precise fixation, and effective bone fusion while minimizing muscle dissection, blood loss, and postoperative pain, achieving rapid neurological and ...
