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 ...

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 ...

An MRI-based semiautomated volumetric quantification of hip osteonecrosis

Malizos, K. N.; Siafakas, M. S.; Fotiadis, D. I.; Karachalios, T. S.; Soucacos, P. N. (2001)

Objective: To objectively and precisely define the spatial distribution of osteonecrosis and to investigate the influence of various factors including etiology. Design: A volumetric method is presented to describe the size ...

Femoral head osteonecrosis: Volumetric MRI assessment and outcome

Bassounas, A. E.; Karantanas, A. H.; Fotiadis, D. I.; Malizos, K. N. (2007)

Effective treatment of femoral head osteonecrosis (FHON) requires early diagnosis and accurate assessment of the disease severity. The ability to predict in the early stages the risk of collapse is important for selecting ...

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 ...

Transosseous application of low-intensity ultrasound at the tendon-bone interface affects the healing rate and up-regulates simultaneously the expression of collagen type i and tRNAGly

Papatheodorou, L. K.; Grafanaki, K.; Giannouli, S.; Fotiadis, D. I.; Stathopoulos, C.; Malizos, K. N. (2008)

The present study investigates the effect of transosseous low-intensity pulsed ultrasound (LiUS) during lingamentization process on the healing at tendon graft-bone interface in rabbits. Analysis of the RT-PCR products ...

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 ...

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 ...
