The Vascularization and Structure of the Human Digital Tendon Sheath as Related to Flexor Tendon Function: An Angiographic and Histological Study

Abstract: The gliding surfaces of the flexor tendons and the tendon sheath are delicate structures of the complex digital flexor system. Beside the fibrous parts, the tendon sheath also exhibits membranous synovial components, which represent a dialysing membrane producing a plasma ultrafiltrate--the synovial fluid. In this study, interest was focused on the vascularization of the synovial sheath. By a microangiographic method it was demonstrated that this membrane is richly vascularized and that the vascular plexus is … Show more

“…The friction between the pulley and the tendon is thought to be an important factor influencing mobilization after repair surgery on the pulley or tendon (9) and may be involved in cumulative trauma disorders (3,8,16). Although the microstructure at the interface of the tendon and the fibrous pulley is thought to be optimal for low friction (13,14), direct measurements of the frictional forces at this interface have not been reported.…”

“…If the tendons are not removed from the sheath during the operation, it results in the decrease of trauma to the vincula and mesotendon of severed tendons. 15,16 This purpose is accessible in our modified way of Sourmelis technique. In this modified technique, there is no need for proximal retraction of tendons (in order to remove the side-to-side tube-to-tendon stitch in the palmar incision) after core sutures insertion.…”

“…Nach Verdan (1972) (Lundborg 1977). Innerhalb der Sehnenscheide erfolgt die Blutversorgung vor allem über die Vincula tendinea, Faserzüge, die Arterien und Venen enthalten und außerdem über die synoviale Umschlagfalte bzw.…”

“…Im Bereich der Sehnenscheide soll die Sehnenheilung jedoch verwachsungsfrei bleiben. Das Granulationsgewebe zwischen den Sehnenstümpfen kommt entweder vom gefäßtragenden Epitenon oder aber von intratendinösen Gefäßen.Ausgedehnte Traumatisierung, un- Experimentelle Untersuchungen anderer Autoren (Lundborg, 1977;Towfigh 1982) zeigten hingegen, dass Sehnen auch zur inneren Zellproliferation und Kollagensynthese als »intrinsic axial healing« fähig sind und ferner dass die Wiederherstellungsaktivität der Sehnen durch Nahtmaterial und Immobilisation verhindert wird, die mechanische Beanspruchung sich aber günstig auf die Sehnenheilung auswirkt. Außerdem kommt es zu einer Entzündungsreaktion, einerseits durch die Gewebehypoxie, die durch strangulierende Nähte oder durch das Fehlen der Synovialis hervorgerufen wird, andererseits durch die Verletzung und ungünstiges Nahtmaterial.…”
