Although tension band wiring fixation of patellar fracture has been the most widely used technique, the metal implants related complications including implant loosening, postoperative pain are very common and additional surgeries are often necessary. A totally metal free technique of transosseous suturing method could outperform the traditional fixation technique.Introduction
Hypothesis
Low total Mini-Mental State Examination (MMSE) score might significantly increase risk of hip fractures. This study was to investigate the effects of MMSE subdomains on the risk of hip fractures with a sex and age matched case control study. A total of 217 patients with first low-trauma hip fractures were matched with 215 hospitalised controls. Seven MMSE subdomains were analysed using conditional logistic regression with adjustment of five important clinical confounders: education level, ADL, physical activities, body mass index and bone mineral density. ROC curve analyses were further used to investigate the predictability of the independent subdomains.Introduction
Materials & Methods
Short-segment posterior instrumentation for spine fractures is threatened by unacceptable failure rates. Two important design objectives of pedicle screws, bending and pullout strength, may conflict with each other. Multiobjective optimization study with artificial neural network (ANN) algorithm and genetic algorithm (GA)Introduction
Hypothesis
Hip fractures have significant excess mortality, but it is unknown how long excess mortality persists. Our study was to explore the short and long term excess mortality after hip fractures, assess the impact of hip fracture on excess mortality and estimate the population attributable risk proportion (PARP) of risk factors for excess mortality. A total of 216 elderly with first time low trauma hip fracture admitted to NTUH were age and sex matched with 215 elder patients from Geriatric Department of the same hospital. All 63 covariates associated with mortality were analyzed using COX regression model. The survival status of these subjects was followed through National Death Registry for 60 months.Backgrounds
