High accuracy of positioning custom triflange acetabular components in tumour and total hip arthroplasty revision surgery: a multicentre cohort study of 35 patients

Autor: Demien Broekhuis, Willemijne M. H. Meurs, Bart L. Kaptein, Sascha Karunaratne, Richard L. Carey Smith, Scott Sommerville, Richard Boyle, Rob G. H. H. Nelissen

Publikováno v: Bone & Joint Open, Vol 5, Iss 4, Pp 260-268 (2024)

Aims: Custom triflange acetabular components (CTACs) play an important role in reconstructive orthopaedic surgery, particularly in revision total hip arthroplasty (rTHA) and pelvic tumour resection procedures. Accurate CTAC positioning is essential t

Preliminary Results of Instantaneous Centre of Rotation Change after Thoracic Instrumentation in Adolescent Idiopathic Scoliosis Patients

Autor: Asma A, Onal C, Eroglu ON, Berk RH

Publikováno v: Malaysian Orthopaedic Journal, Vol 16, Iss 3, Pp 120-127 (2022)

INTRODUCTION: The instantaneous centre of rotation (ICR) is the centre of motion with zero velocity where a rigid body moves in a particular plane. ICR, as a dynamic measurement, gives more accurate results in terms of quality and quantity of the ver

Displacement of the Hip Center of Rotation After Arthroplasty of Crowe III and IV Dysplasia : A Radiological and Biomechanical Study

Autor: Mansour Abolghasemian, Allan E. Gross, Saeid Samiezadeh, Habiba Bougherara, Mohammad Taghi Ghazavi, Davood Jafari

To study the direction and biomechanical consequences of hip center of rotation (HCOR) migration in Crowe type III and VI hips after total hip arthroplasty, post-operative radiographs and CT scans of several unilaterally affected hips were evaluated.

Center of rotation analysis for thoracic and lumbar 3-column osteotomies in patients with sagittal plane spinal deformity: insights in geometrical changes can improve understanding of correction mechanics

Autor: Juliane Koller, Heiko Koller, Axel Hempfing, Isabel C. Hostettler, Alexandre Ansorge, Wolfgang Hitzl, Dezsoe Jeszenszky

Publikováno v: Journal of Neurosurgery: Spine. 36:440-451

OBJECTIVE Three-column osteotomy (3CO) is used for severe spinal deformities. Associated complications include sagittal translation (ST), which can lead to neurological symptoms. Mismatch between the surgical center of rotation (COR) and the concept

Effect of reverse total shoulder arthroplasty humeral inclination on glenohumeral range of motion, deltoid force, and glenoid strain: a biomechanical study

Autor: Felix Dyrna, Vivek Chadayammuri, Anthony A. Romeo, Knut Beitzel, Bastian Scheiderer, Taylor Wiley, Elifho Obopilwe, Sheeba M. Joseph, Augustus D. Mazzocca, Mark P. Cote

Publikováno v: Seminars in Arthroplasty: JSES. 32:116-124

Background Reverse total shoulder arthroplasty (RSA) primarily varies between 2 implant design options: a 135 humeral stem inclination that closely resembles anatomic orientation, versus the Grammont-style 155 humeral stem inclination that further me

Lateralized vs. classic Grammont-style reverse shoulder arthroplasty for cuff deficiency Hamada stage 1-3: does the design make a difference?

Autor: Florian Freislederer, Laurent Audigé, Alex Marzel, Markus Scheibel, Felix Toft, David Endell

Publikováno v: Journal of Shoulder and Elbow Surgery. 31:341-351

BACKGROUND Reverse shoulder arthroplasty (RSA) with a lateralized design is thought to improve outcomes. Our aim was to compare RSA with the classic Grammont prosthesis against a prosthesis with 135° inclination and a lateralized glenosphere for cuf

Biomechanical consequences of the intervertebral disc centre of rotation kinematics during lateral bending and axial rotation

Autor: Allais, Roman, Capart, Antoine, Da Silva, Anabela, Boiron, Olivier

Publikováno v: Scientific Reports
Scientific Reports, 2023, 13 (1), pp.3172. ⟨10.1038/s41598-023-29551-7⟩

The location of the instantaneous centre of rotation (ICR) of a lumbar unit has a considerable clinical importance as a spinal health estimator. Consequently, many studies have been conducted to measure or estimate the ICR during rotations in the thr
