Passive Skeletal Muscle Excursion after Tendon Rupture Correlates with Increased Collagen Content in Muscle
PURPOSE This study was designed to measure time-dependent changes in muscle excursion and collagen content after tenotomy, and to analyze the correlation between muscle excursion and collagen content in a rabbit model. MATERIALS AND METHODS Twenty-four rabbits underwent tenotomy of the second extensor digitorum longus (EDL) muscles on the right legs and were randomly assigned to three groups ...
متن کاملCorrelation between change in muscle excursion and collagen content after tendon rupture and delayed repair
BACKGROUND The objectives of the present study were to compare changes in muscle excursion, total collagen, and collagen subtypes after tenotomy over time and after delayed tendon repair. METHODS Tenotomy on the extensor digitorum tendon of the right second toes of 48 New Zealand White rabbits was performed; toes on the left leg were used as controls. Passive muscle excursion, total collagen ...
متن کاملPassive muscle-tendon amplitude may not reflect skeletal muscle functional excursion.
PURPOSE To quantify the gain in muscle mobility with progressive release of surrounding connective-tissue structures and to compare this property with the known architecture of each muscle. METHODS Each of 5 different muscle tendon units (extensor carpi radialis brevis, extensor carpi radialis longus, flexor carpi ulnaris, flexor digitorum superficialis, pronator teres) was released from its ...
متن کاملIncreased collagen content in insulin-resistant skeletal muscle.
Oversupply and underutilization of lipid fuels are widely recognized to be strongly associated with insulin resistance in skeletal muscle. Recent attention has focused on the mechanisms underlying this effect, and defects in mitochondrial function have emerged as a potential player in this scheme. Because evidence indicates that lipid oversupply can produce abnormalities in extracellular matrix...
متن کاملIncreased Serial Sarcomere Number does not Result in Increased Muscle Excursion after Tendon Transfer Surgery
Introduction: Muscles adapt experimentally by adding sarcomere in series in response to stretch outside of their physiologic range in an animal tendon transfer model [1]. If this finding also applies to muscles after tendon transfer surgery, this would be desirable, as intraoperative measurements reveal that transferred muscles are typically overstretched to the point where they are predicted t...
