AIMS Tendons are crucial for optimal muscle force transfer and subject to changes with aging which may impair functional ability of elderly individuals. Achilles is the largest and the strongest tendon in the body; therefore it is an excellent site for the radiologic investigation of aging of tendons. Sonoelastography (SE) is a new ultrasound-based imaging technique that provides information on...

Rabbit forelimb tendons incubated for 15 or 21 days at 35 degrees C in the presence of 8 or 24 mg of glucose/ml were shown to change their chemical, biochemical and mechanical characteristics. The tendons treated with glucose contained up to three times as much hexosyl-lysine and hexosylhydroxylysine as did control tendons as judged by assay of NaB3H4-reduced samples. Measurement of the force g...

The treatment of severe lesions peroneus longus and brevis tendons is a challenge for orthopedists, little described in theliterature about the epidemiology. Most articles focus on single lesion one tendons, rarely describing what to do whenboth are severely ill. This case report will show discuss surgical technique when both injured. Level Evidence III; Case Report Literature Review.

PURPOSE To measure the size of the Achilles tendons in congenital clubfeet using ultrasonography before and after percutaneous tenotomy. METHODS 15 boys and 12 girls (39 feet) aged one to 11 (mean, 5) months with idiopathic clubfeet underwent percutaneous tenotomy (Ponseti method). The size of each Achilles tendon was measured ultrasonographically by a single radiologist before and after surg...

BACKGROUND This study investigated changes in tendon vascularity in 102 (67 men and 35 women) volleyball players over a 6 month competitive season. METHODS Athletes were examined with both grey scale ultrasound and standardised colour Doppler settings. Vessel length and pain were measured each month on five separate occasions. Vascular tendons were divided into (i) those that were vascular on...

Mechanical stress is an important modulator of connective tissue repair. However, the effects on tendon healing are very poorly defined, preventing optimal use of mechanical stress. We hypothesized that early voluntary exercise initially retards tendon repair but results in a faster recovery rate at longer term. Male Wistar rats were injured by a collagenase injection in the Achilles tendon, an...

The term “ attrition “ rupture of tendons was coined by Vaughan-Jackson who, in 1948, reported two cases of rupture of extensor tendons through attrition at the inferior radio-ulnar joint. These ruptures were caused by bony irregularities at the distal end of the ulna. Spontaneous ruptures of flexor tendons in rheumatoid arthritis were fully described by Lame and Vainio in 1955. Pathomechanics ...

BACKGROUND Dislocation or subluxation of the peroneal tendons out of the peroneal groove under a torn or avulsed superior peroneal retinaculum has been well described. We identified a new subgroup of patients with intrasheath subluxation of these tendons within the peroneal groove and with an otherwise intact retinaculum. METHODS The cases of fifty-seven patients with painful snapping of the ...
