Staged reduction and stabilisation in chronic atlantoaxial rotatory fixation

, 2002
We present seven children with atlantoaxial rotatory fixation (AARF) of more than three months’ duration after an injury to the upper cervical spine. The deformity was irreducible by skull traction. MRI and MR angiography (MRA) of the vertebral arteries

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, Volume 309, Issue 11, Page 3137-3168, November 2026.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Pedicled Vascularized Occipital Bone Graft to Supplement Atlantoaxial Arthrodesis for the Treatment of Pseudoarthrosis

, 2019
Atlantoaxial pseudoarthrosis is a challenging postoperative complication. The use of a local, vascularized bone graft, without free tissue transfer, to support a revision atlantoaxial fusion has not been previously described. We report the first surgical

Clinicoradiological evaluation and outcome assessment of single-stage posterior correction of atlantoaxial dislocation [PDF]

, 2023
Background: Atlantoaxial dislocation (AAD) refers to loss of stability between atlas and axis vertebrae, resulting in loss of normal articulation. It may be due to congenital, traumatic, or inflammatory reasons.

Bilateral C1-C2 transarticular screw and C1 laminar hook fixation and bone graft fusion for reducible atlantoaxial dislocation: a seven-year analysis of outcome. [PDF]

PLoS ONE, 2014
BACKGROUND: Bilateral C1-2 transarticular screw and C1 laminar hook fixation was developed on the basis of transarticular screws fixation. The modified technique has showed a better biomechanical stability than established techniques in previous study ...

Atlantoaxial dislocation with congenital “sandwich fusion” in the craniovertebral junction: a retrospective case series of 70 patients

BMC Musculoskeletal Disorders, 2020
Background In the setting of congenital C1 occipitalization and C2–3 fusion, significant strain is placed on the atlantoaxial joint. Vertebral fusion both above and below the atlantoaxial joint (i.e., a “sandwich”) creates substantial instability.

Effectiveness of Resistance Training in People With Down Syndrome: Systematic Review and Meta‐Analysis

Journal of Applied Research in Intellectual Disabilities, Volume 39, Issue 5, September 2026.
ABSTRACT Background We aimed to evaluate the effectiveness of resistance training (RT) in people with Down syndrome (DS) as a way of improving strength, physical and metabolic function, and possible adverse effects. Methods Systematic review and meta‐analysis of RCTs in PubMed, PEDro, Scopus, and WoS databases in September‐2023, registered in PROSPERO (

Axial osteochondroma causing myelopathy – A technical note and discussion on atlantoaxial fusion following C2 laminectomy

, 2019
Osteochondromas are one of the commonest benign bone tumours, but are rarely found in the spine. Cord compression due to these lesions is even rarer. We describe a case of a C2 lamina osteochondroma causing cord compression in a 20 year old patient who ...

Modification of Goel–Harms Technique in the Surgical Treatment of Atlantoaxial Subluxation after Grisel Syndrome

Global Spine Journal, 2015
Introduction Many etiologies can lead to atlantoaxial subluxation. In Grisel syndrome, this subluxation occurs spontaneously after inflammatory processes of the head and neck. Nonsurgical treatment most often resolves the symptoms; however, in some cases,
