We introduce phi-3-mini, a 3.8 billion parameter language model trained on 3.3 trillion tokens, whose overall performance, as measured by both academic benchmarks and internal testing, rivals that of models such Mixtral 8x7B GPT-3.5 (e.g., phi-3-mini achieves 69% MMLU 8.38 MT-bench), despite being small enough to be deployed phone. The innovation lies entirely in our dataset for training, scaled-up version the one used phi-2, composed heavily filtered web data synthetic data. is also further...
Progressive Collapsing Foot Deformity (PCFD) presents various deformities. While medializing displacement calcaneal osteotomy (MDCO) and lateral column lengthening (LCL) are commonly employed as corrective surgeries, their impact on foot structure functionality necessitates detailed biomechanical analysis. The objective of this study is to analyze the reliability using talonavicular uncoverage percentage (TUP) a metric for assessing degree forefoot abduction. Seven subject-specific flatfoot...
Abstract Background Evans and Hintermann lateral column lengthening (LCL) procedures are both widely used to correct adult acquired flatfoot deformity (AAFD), have shown good clinical results. The aim of this study was compare these two in terms corrective ability biomechanics influence on the Chopart subtalar joints through finite element (FE) analysis. Methods Twelve patient-specific FE models were established validated. osteotomy performed between medial posterior facets joint; while,...
Abstract Background A simulation and model (SM) teaching aid using 3D printing was developed to improve a training course for total hip arthroplasty of adult developmental dysplasia the (adult DDH-THA). We named this new method Surgery Simulation Teaching based on Real Reconstruction Aid (RRA-SST). prospective randomized comparison performed with traditional surgical live evaluate effectiveness RRA-SST DDH-THA. Methods Twenty-six trainees, who were already practicing but not experienced,...
Several approaches to spring ligament reconstruction have been reported. However, a comparative study of nonanatomic and anatomic techniques with respect biomechanical responses, such as kinematics contact characteristics, has not previously performed via finite element analysis. The purpose this was evaluate the results reconstructions A three-dimensional model foot developed validated, four methods were simulated. talonavicular dorsiflexion abduction, hindfoot valgus, characteristics in...
The Evans calcaneal lengthening osteotomy procedure is widely used for correcting progressive collapsing foot deformity. However, it can result in overcorrection and degenerations of the calcaneocuboid joint. Different shapes graft have been osteotomy, but potential differences their biomechanical effects still unclear. present study was designed to explore shape improve avoid or minimize detrimental effects.Twelve patient-specific finite element models were established validated. A...
Nonanatomic tenodesis reconstruction procedures have been used for lateral ankle ligament reconstruction. However, there has no comparison of Watson-Jones, Evans, and Chrisman-Snook with respect to biomechanical characteristics such as kinematics, ligaments grafts stresses using finite element analysis.A three-dimensional model the including seven bony structures, cartilage nine principal surrounding joint complex was developed validated. In addition intact model, combined anterior...
A great deal of research suggests that arthroscopic ankle fusion (AAF) has advantages over open (OAF), but these outcomes would be imprecise because a selection bias. The purpose this study is to verify which better for fusion, AAF or OAF. We regrouped the OAF group into two subgroups according whether osseous operation type same as group. goal minimize impact disease severity, thereby reducing bias some extent.We retrospectively analyzed data in our hospital between July 2015 and October...
<title>Abstract</title> Background Over the past seven years, our team has designed a simulated operation combined with patient-specific instrumentation (SO-PSI) assisted supramalleolar osteotomy (SMOT) method and applied it in clinic. This study aimed to evaluate differences between SO-PSI technology conventional (CO) for SMOT preoperative planning, intraoperative application, postoperative curative effect. Methods We retrospectively analyzed data collected from hospital October 2014...
Abstract Background There are several types of tenodesis reconstruction designed for subtalar instability. However, no comprehensive comparison has been conducted among these procedures in terms their correcting power so far. The objective this study is to evaluate the biomechanical behaviors 5 representative through finite element analysis. Methods Finite models were established and validated based on one our previous studies. Pisani interosseous talocalcaneal ligament (ITCL)...
Abstract Background Traditional methods for minimally invasive internal fixation (MIIF) of calcaneal fractures require extensive intraoperative fluoroscopy, and fracture recovery is usually not ideal. We developed a new surgical procedure using digital simulation constructed patient-specific instrument (PSI) that we used during the operation. This study investigated whether PSI-assisted MIIF enables rapid accurate execution preoperative plan. Methods retrospectively analyzed patients with...
