Background The improvement of bone ingrowth into prosthesis and enhancement the combination range between are important for long-term stability artificial joints. They focus research on uncemented Porous materials can be potential use to solve these problems. Objectives/Purposes This aims observe characteristics new porous Ti-25Nb alloy its biocompatibility in vitro, provide basic experimental evidence development prostheses or implants tissue regeneration. Methods alloys with different...
Understanding the morphological variability of distal tibia can help design tibial components total ankle implants. This study aimed to assess shape bone, utilizing statistical modeling (SSM) technique. A 229 bones were analyzed through CT scans develop SSM models. Principal component analysis (PCA) was employed characterize variation across male, female, and overall groups. The geometric parameters resected surfaces at 10-mm level above articular surface compared. first seven principal...
Implant loosening in tibia after primary total ankle replacement (TAR) is one of the common postoperative problems TAR. Innovations implant structure design may ideally reduce micromotion at bone-implant interface and enhance fixation initial stability, thus eventually prevents long-term loosening. This study aimed to investigate (1) biomechanical characteristics (2) influence features, such as radius, height, length.A 101 finite-element models were created based on four commercially...
Abstract Implant loosening and bearing surface wear remain the most common failure problems of total ankle arthroplasty (TAA). One main factors leading to these is nonphysiologic design articular surfaces. The goals this study were reveal effects anatomical medial‐lateral borders height differences, coronal sagittal radii on joint kinematics, contact mechanics, implant‐bone micromotion in TAA. A previously developed validated musculoskeletal (MSK) multibody dynamics (MBD) modeling method TAA...
Fitting the surface morphology of talar trochlea is one common methods to define geometric axis tibiotalar joint (GATJ). However, in vivo motion such during gait has not been fully investigated.The ankle kinematic data fifteen volunteers were collected by a dual fluoroscopic imaging system with model-image registration method. The GATJ was defined sphere-fitting medial or lateral part trochlear talus. position and orientation this measured. To verify axis, distances feature points talus also...
The implant design of the talar component for total ankle replacement (TAR) should match surface morphology talus so that replaced can restore natural motion tibiotalar joint and may reduce postoperative complications. purpose this study was to introduce a new 3D fitting method (the two-sphere trochlea with three resection planes) approximate shape upper part Chinese population. 90 models tali from CT images healthy volunteers were used in study. Geometrical morphological measurements...
Objective To evaluate the surgical techniques and 2-year follow-up results of Mast Quadrant-assisted modified transforaminal lumbar interbody fusion (TLIF).Methods From September 2006 to October 2008,54 patients with single-level degeneration disease were treated by Quadrantassisted TLIF.Under guidance C-arm,the Quadrant's retractor was placed lower articular process upper vertebrae 1/2-2/3 lamina,flavum ligament hyperplastic cohesive part removed,the nerve roots central canal...
Purpose The talar bone plays a crucial role in ankle biomechanics and stability. Understanding the shape variability of within specific populations is essential for various clinical applications. In this study, we aimed to investigate mean principal human Chinese population using statistical modeling (SSM). Methods CT scans 214 tali were included create SSM models. Principal component analysis was used describe variation among male, female, overall groups. Results largest amount three groups...
