The appearance of the 'grand-piano sign' on anterior resected surface femur has been considered to be a marker for correct femoral rotational alignment during total knee replacement. Our study was undertaken assess quantitatively morphological patterns after resection with various angles external rotation, using computer-simulation technique. A 50 right distal femora varus osteoarthritis in Korean patients were scanned computerised tomography. Computer image software used simulate cut, which...
Shoulder pressure redistribution is jointly affected by backpack loads and belt support. However, the combined effect of both factors has rarely been fully evaluated. Here, we studied coupled support on shoulder redistribution. All twenty-eight healthy male subjects underwent eight loading conditions with chest hip belts fastened (CH) unfastened (CON) in four where weighed 7.5, 15, 22.5, 30% body weight (BW). distribution was quantified through a pressure-sensing vest mat. The results showed...
Abstract Corrosion at the taper/trunnion interface of total hip replacement (THR) often results in severe complications. However, underlying mechanisms biotribocorrosion during long-term walking gait cycles remain to be fully understood. In this study, a joint simulator was therefore instrumented with an electrochemical cell for in-situ monitoring tribocorrosion evolution metal-on-polyethylene (MoP) THR typical gait. addition, mechanism investigated via surface and chemical...
Fretting corrosion as one of the leading causes for failure modular hip prostheses has been associated with micromotion at head-neck taper junction. Decomposition is helpful to promote development more realistic experiments investigating mechanisms junction in total arthroplasty. The aim this study was decompose complex three-dimensional into multiple fundamental modes, including three translational and rotational components. A finite element model composed junction, liner acetabular cup a...
有效负载, 本研究以二氰二胺为前驱体, 通过溶解-再结晶-热处理原位负载工艺
Abstract Ti6Al4V alloy–CoCrMo alloy pair is commonly applied for modular head–neck interfaces artificial hip joint. Unfortunately, the fretting corrosion damage at this interface seriously restricts its lifespan. This work studied of Ti6Al4V–CoCrMo in calf serum solution. We established material pair’s running condition map (RCFM) regarding load and displacement, revealed mechanism various regimes, namely partial slip regime (PSR), mixed (MFR), gross (GSR). The was mainly abrasive wear...
To enhance the prevention of shoulder pressure injuries in various load-bearing populations, effects morphology on distribution were investigated. In this study, 69 participants underwent three-dimensional scanning, and based morphological characteristic indicators, they classified into four types. From these, 28 selected to have within regions measured using a pressure-sensing vest while carrying backpack load equivalent 15% their body weight. The results indicated that variations...
The friction and wear behaviors of cartilage replacement materials against articular are considered essential characteristics that determine the function performance replacement. Previous studies have often been conducted under a reciprocal linear motion, while cross-shear motion has shown to widely exist in joints. difference resulting between effect bearing surface roughness on frictional should be further investigated. In this study, experimental tribology investigations were for commonly...
Abstract Ultralow-wear polyethylene (ULWPE), a type of homocomposite with excellent wear resistance, has recently been reported, however its underlying mechanism yet to be clarified. In the current study, three different molecular weights ULWPE from 205 748 Kg/mol, were experimentally evaluated on multidirectional motion pin-on-disk (POD) tester under contact pressure 2 4 MPa, compared conventional UHMWPE. The high resistance was investigated respect mechanical, microstructural, and surface...
Objective To investigate the influence of radio-frequency ablation(RFA) combined with 5-Fu-MAMS injection on ablation volume. Methods The subjects used in this experiment were fresh ex vivo bovine livers.Three groups set up: Group Ⅰ, RFA alone; group Ⅱ, 5-fluorouracil; Ⅲ, 5-fluorouracil magnetic albumin microspheres.The size and shape coagulation necrosis zones observed measured.Single factor analysis variance was to analyze affecting factors for lesions.Macroscopic microscopic...
The current treatment strategy for rectal cancer is a comprehensive centered on surgery. application of total mesorectal excision (TME) has significantly reduced the local recurrence rate and improved survival prognosis, but series pelvic organ dysfunction caused by autonomic nerve injury during operation will reduce postoperative quality life patients. Pelvic preserving (PANP) radical proctectomy emerged, biggest challenge in implementation process this technology accurate identification...
To analyze the importance of bone quality, we studied 21 primary compressive trabecular system by micro-computed tomography(micro-CT), finite element analysis and destructive mechanical test. Significant correlations were found between histomorphometry biomechanical parameters. The results indicate that quality is determined more its combined micro-structural parameters (histomorphometry) than only. Assessment may become important not only for assessment but also prediction fracture risk...
