“…However, [22] also monitored 100 patients after distraction (healing curves reported only for the cited three cases) and, interestingly, it reported that in all cases the fixators were removed when supported less than 10% of the total load, without cases of refractures. Also the predicted curves of the VMs were in agreement with in-vivo literature studies [20,23]. Burny et al [20] monitored the leg fracture healing in 390 patients from 1965 to 1981 by measuring the external fixator strain during healing.…”

“…This work examines an approachconsisting in monitoring of the load transfer from the fixator to the bone during healing. This method, largely investigated in the 80-90s, was pursued by instrumenting the fixators, both the internal [18,19] and external [20][21][22][23] ones, by means of strain gauges [18][19][20] or load cells [21][22][23]. The advantage of strain gauges in external fixation is that their application does not require any modifications of the fixator.…”

Section: Stabilität Der Osteosynthese Und Interfragmentäre Bewegungunclassified
“…Während Frakturspalten von 1 mm sehr schnell überbrückten und gröûere interfragmentäre Bewegungen bis zu einer Gröûe von 31 % der Spaltbreite die Callusbildung und die Biegesteifigkeit verbesserten, waren bereits bei 2 mm Spaltbreiten und flexibler Fixation geringe Biegesteifigkeiten des Heilungsgebiets zu beobachten. Dies wird gestützt durch Ergebnisse einer umfangreichen Studie an 100 Tibiafrakturen, die mit einem monolateralen Fixateur externe versorgt wurden [7]. Während bei 1 und 2 mm Spalten eine gröûere interfragmentäre Bewegung mehr Callus erzeugte, führte dies bei einem 6 mm Spalt zu einer signifikant kleineren Callusbildung die keine Spaltüberbrückung erzielte.…”

Section: Externe Stimulation Der Callusbildungunclassified
Interfragmentary movement and size of the fracture gap influence fracture healing. Limited movements promote callus formation and may result in increased mechanical stability. Although larger movements still promote callus formation, the bony consolidation of the fracture is hampered. Fracture healing is also hampered if the size of the fracture gap is too large. A combination of large movement and large gap bears the risk of non-union. Therefore, having in mind a minimally invasive surgical approach, one should strive for good reduction of the fracture ends and flexible yet stable osteosynthesis. Dynamization of the fracture by enabling axial movement will close the fracture gap, stimulate tissue differentiation and possibly accelerate the healing process. External mechanical stimulation, however, has not been shown to effectively enhance the healing process under flexible fixation or in load-bearing patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
