EFFECT OF TRANSOSSEOUS APPLICATION OF LOW-INTENSITY ULTRASOUND AT THE TENDON GRAFT-BONE INTERFACE HEALING: GENE EXPRESSION AND HISTOLOGICAL ANALYSIS IN RABBITS
Papatheodorou, L. K.; Malizos, K. N.; Poultsides, L. A.; Hantes, M. E.; Grafanaki, K.; Giannouli, S.; Ioannou, M. G.; Koukoulis, G. K.; Protopappas, V. C.; Fotiadis, D. I.; Stathopoulos, C. (2009)The present study investigates the effect of transosseous low-intensity pulsed ultrasound (LiUS) on the healing at tendon graft-bone interface, in molecular and histological level. The anterior cruciate ligament (ACL) in ... -
Guided ultrasound wave propagation in intact and healing long bones
Protopappas, V. C.; Fotiadis, D. I.; Malizos, K. N. (2006)Ultrasonic evaluation of bone fracture healing has been traditionally based on the measurement of the propagation velocity of the first arriving signal (FAS). However, the FAS in general corresponds to a lateral wave that ... -
Three-dimensional finite element modeling of guided ultrasound wave propagation in intact and healing long bones
Protopappas, V. C.; Kourtis, I. C.; Kourtis, L. C.; Malizos, K. N.; Massalas, C. V.; Fotiadis, D. I. (2007)The use of guided waves has recently drawn significant interest in the ultrasonic characterization of bone aiming at supplementing the information provided by traditional velocity measurements. This work presents a ... -
Transosseous application of low-intensity ultrasound for the enhancement and monitoring of fracture healing process in a sheep osteotomy model
Malizos, K. N.; Papachristos, A. A.; Protopappas, V. C.; Fotiadis, D. I. (2006)The purpose of this study is twofold: (a) to investigate the application of transosseous low-intensity pulsed ultrasound (LiUS) on the enhancement of fracture healing and (b) to demonstrate the ability of transosseous ... -
An ultrasound wearable system for the monitoring and acceleration of fracture healing in long bones
Protopappas, V. C.; Baga, D. A.; Fotiadis, D. I.; Likas, A. C.; Papachristos, A. A.; Malizos, K. N. (2005)An ultrasound wearable system for remote monitoring and acceleration of the healing process in fractured long bones is presented. The so-called USBone system consists of a pair of ultrasound transducers, implanted into the ...
