Reconstruction of pelvis girdle stability after tumor-induced hemipelvectomy remains challenging. We surgically treated 13 patients with custom-made, three-dimensional printed hemipelvic prostheses. aim to identify the preliminary outcomes for who have been managed more mixed regions prosthetic pelvic reconstruction and feasibility two reconstructive systems.Seven male 6 female at our center between January 2019 May 2021 were included. There 11 primary sarcomas 2 solitary bone metastases....
To test the biomechanical properties of 3D printed tantalum and titanium porous scaffolds.Four types scaffolds with four alternative pore diameters, #1 (1000-700 μm), #2 (700-1000 #3 (500-800 #4 (800-500 were molded by selective laser melting technique, tested scanning electronic microscope, uniaxial-compression tests, Young's modulus tests; they compared same size pig femoral bone scaffolds.Under equivalent stress scaffold was 411 ± 1.43 MPa, which significantly larger than (P < 0.05). 2.61...
Background: Prosthetic reconstruction after type I + II+ III internal hemipelvectomy remains challenging due to the lack of osseointegration and presence giant shear force at sacroiliac joint. The purpose this study was evaluate biomechanical properties novel 3D-printed, custom-made prosthesis with pedicle screw-rod system sacral tray using finite element analysis. Methods: Four models that included one intact pelvis were established for validation. Forces 500 N 2,000 applied, respectively,...
Objective To explore the feasibility of 3D printed customized guides assisting precise drilling Kirschner wires in subtalar joint arthrodesis. Methods We retrospectively reviewed data 29 patients (30 joints) who underwent arthrodesis between 1 July 2013 and 31 December 2017. The were designed on a full‐scale polylactic acid model made from computed tomography (CT) by Model Intestinal Microflora Computer Simulation (MIMICS) software, which manufactured printing technology. A total 14 joints...
To accurately drill the Kirschner wire with help of 3D-printed personalized guide and to evaluate feasibility 3D technology as well outcome surgery.Patients' DICM data ankle via CT examinations were introduced into MIMICS software design guides. Two 2mm wires drilled guides; C-arm fluoroscopy was used confirm position before applying cannulated screws. The patients who underwent arthrodesis divided two groups. experimental group adopted guides, while control received traditional method,...
Chronic inflammation and bone defects after total knee arthroplasty are a challenge for the orthopedic surgeon. There have been few reports on application of three-dimensional (3D) printed porous tantalum prosthesis in such situations. We report an 83-year-old female patient who presented to our clinic with consistent pain left 10 years severe decline mobility 2 years. inflammation, loosening tibial defect, osteoporosis were diagnosed. The was treated computer designed manufactured,...
Background Three-dimensional (3D) reconstruction has been used for various diseases, but few reports have described its application in pelvic after removal of giant chondrosarcoma. Case describing the clinical personalized 3D-printed titanium implants are needed future reference. presentation: We herein describe a 29-year-old woman with chondrosarcoma treated 3D implant. The surgery was successful, and patient recovered significant pain relief good functional recovery surgery. No...
The aim of this research was to explore the hypothesis that acupuncture at sphenopalatine ganglion (SPG), a new method acupuncture, would be more efficacious and safe than traditional in treatment persistent allergic rhinitis (PAR).
Sagliker syndrome (SS) is characterized by a severe uglifying facial appearance resulting from untreated or inadequately treated secondary hyperparathyroidism (SHPT). To date, the craniofacial morphology of patients with SS has yet to be analyzed. The present research sought cephalometrically evaluate features and perform an in-depth analysis their serum biochemical parameters, aim furthering theoretical basis for early diagnosis prevention SS.A retrospective chart review 9 who fulfilled...
Accurate preoperative localization of abnormal parathyroid glands is crucial for successful surgical management secondary hyperparathyroidism (SHPT). This study was conducted to compare the effectiveness MRI, 4D-CT, and ultrasonography (US) in localizing lesions patients with SHPT.We performed a retrospective review prospectively collected data from tertiary-care hospital identified 52 who received MRI and/or 4D-CT US 99mTc-MIBI subsequently underwent surgery SHPT between May 2013 March...
Artificial joint revision surgery, as an increasingly common surgery in orthopedics, often requires patient-specific prostheses to repair the bone defect. Porous tantalum is a good candidate due its excellent abrasion and corrosion resistance osteointegration. Combination of 3D printing technology numerical simulation promising strategy design prepare porous prostheses. However, clinical cases have rarely been reported, especially from viewpoint biomechanical matching with patient's weight...
Embedding schottky barrier diode (SBD) within the 4H-SiC MOSFET (SBD-MOS) can suppress bipolar conduction of body-diode while minimizes additional chip size and cost. A 6500 V SBD-MOS is fabricated high temperature test performed 6500V conventional (Conv-MOS) employed as comparison. The output, transfer I-V performances under different have been studied percentage unipolar current in at evaluated.
To explore the evaluation effect of ultrasonography and Pirani score on tarsal deformity, treatment pseudo-correction congenital clubfoot in infants young children, correlation between two methods.
Purpose Parathyroidectomy is beneficial in tertiary hyperparathyroidism (THPT) consequent to chronic renal failure. The craniofacial morphology of patients who undergo total parathyroidectomy and autologous transplantation (tPTX + AT) has not been widely studied. This study assessed the efficacy tPTX AT THPT evaluated possible improvements features. Methods retrospective analysis included were diagnosed with medically refractory had undergone between September 2013 May 2021. VAS was used...
Redundant Switched-mode Power supplies (SMPSs) are commonly used to improve electronic systems’ reliability, and accurate estimation of the current sharing state is significant for evaluating system’s health. Currently, mainly realized by using sensors detect each branch’s current, deployment maintenance costs high. In this paper, a method power supply based on LSTM recurrent neural network proposed. By taking advantage subtle differences in inherent spectral characteristics SMPSs, only...
Objective: To investigate the clinical outcomes and effects of distal oblique osteotomy Youngswick in treatment grade Ⅲ Ⅳ hallux rigidus. Methods: Totally 29 patients (33 feet) suffered from rigidus who received first metatarsal Ningbo NO.6 Hospital May 2013 to December 2018 were analyzed retrospectively. Among them, there 10 males 19 females. The average age was (56±6) years. Seventeen cases (18 underwent metatarsal, 12 (15 osteotomy. overall evaluations investigated before operation at...
As high voltage pulse power capacitors, ceramic capacitors are widely used in generators, trigger circuits, laser and other fields. The capacitance of is closely related to the direct current (DC) bias voltage. However, measurement methods can only achieve a DC 1 kV, which cannot meet requirements environments. This paper proposes method that accurately measure under 3 kV. decouples frequency alternating small signals realizes low calibration isolation. experimental results show proposed...
