Biomechanical Effects of Two Types of 3D‐Printed Prosthesis Reconstruction After Single‐Segmental Total En Bloc Spondylectomy: A Finite Element Analysis

Orthopaedic Surgery, EarlyView.
The choice of prosthesis in spinal reconstruction plays an essential role in patients' postoperative outcomes. This study aims to investigate the biomechanical effects of two types of 3D‐printed prosthesis and titanium mesh cage (TMC) after total en bloc spondylectomy.

Biomechanical Study between the Rigid and Dynamic Fixation Systems of the Spinal Column Analyzed by the Finite Element Method

Nano Biomedicine and Engineering, 2017
Orthopedic fixation devices are widely used in treatment of spinal diseases. It is expected that application of dynamic stabilization confers valuable movement possibility besides its main role of load bearing.

Autonomous Frameless Spine Registration and Robot‐Assisted Surgery

Orthopaedic Surgery, EarlyView.
Workflow of a contactless, frame‐free, robot‐assisted vertebra registration system. Preoperative CT data establish vertebra {V} and mask {Mpre} coordinate systems. Their relationship is computed, and intraoperatively the robot recognizes the skin‐affixed mask, defining {Mintra}.

Generalized Joint Hypermobility in Adolescent Idiopathic Scoliosis: Greater Curve Flexibility, Larger Thoracic Kyphosis, but Higher Complication Risk

Orthopaedic Surgery, EarlyView.
Generalized joint hypermobility in adolescent idiopathic scoliosis is linked to greater spinal flexibility and increased thoracic kyphosis, but also elevates the risk of surgical complications, despite no significant differences in patient‐reported outcomes.

Derivation of inter-lamellar behaviour of the intervertebral disc annulus

, 2015
The inter-lamellar connectivity of the annulus fibrosus in the intervertebral disc has been shown to affect the prediction of the overall disc behaviour in computational models. Using a combined experimental and computational approach, the inter-lamellar

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Nonlinear dynamics of the human lumbar intervertebral disc

, 2015
Systems with a quasi-static response similar to the axial response of the intervertebral disc (i.e. progressive stiffening) often present complex dynamics, characterized by peculiar nonlinearities in the frequency response.
