BACKGROUND Tendon transfers can be a surgical treatment option in managing younger, active patients with massive irreparable rotator cuff tears. The purpose of this article is to provide an overview of the use of tendon transfers to treat massive irreparable rotator cuff tears and to summarize clinical outcomes. METHODS A selective literature search was performed and personal surgical experie...

Introduction: The Achilles tendon is commonly involved in mechanical, degenerative and inflammatory disease. Ultrashort echo time (UTE) imaging allows the tendon to be directly imaged, even when normal or only mildly diseased [1]. Off resonance saturation has been used for introducing contrast into UTE images; near resonance this reflects T2 whereas far from resonance magnetization transfer (MT...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

BACKGROUND Numerous surgical techniques have been described to address injuries to the coracoclavicular ligaments. PURPOSE To compare the biomechanical properties of tendon graft reconstructions with those of the native coracoclavicular ligaments and various other repair methods. STUDY DESIGN Controlled laboratory study. METHODS Eleven fresh-frozen human cadaveric shoulders were tensile t...

BACKGROUND Disruption of the plantar plate of the lesser metatarsophalangeal (MTP) joints leads to significant instability. Despite the fact that plantar plate disorders are common, the best mode of treatment remains controversial with operative treatments having variable and somewhat unpredictable clinical outcomes. METHODS Lesser MTP joints from the second, third, and fourth toes from fresh...

PURPOSE To show biomechanically that the brachioradialis (BR) muscle can be transferred to restore key pinch and forearm pronation simultaneously. METHODS Nine fresh-frozen forearms were thawed and instrumented with a custom muscle-tendon excursion jig. Maximum BR muscle-tendon excursion was measured with the wrist and thumb mobile. Muscle-tendon excursion then was measured from 60 degrees of...

Sarcomere number change was investigated in an animal model of tendon transfer. In 9 adult New Zealand white rabbits, the flexor digitorum longus muscle was cut distally and transferred and woven into the tibialis anterior tendon. Ankles were then immobilized for 3 weeks in 75 degrees flexion. Transferred flexor digitorum longus muscles were harvested and complete architectural analysis was per...

OBJECTIVE To describe and evaluate the rehabilitation concept after posterior deltoid to triceps transfer in patients with tetraplegia. DESIGN Retrospective observational study. SETTING Rehabilitation units. PARTICIPANTS Patients with tetraplegia who had posterior deltoid to triceps tendon transfer and had muscle strength measurements 1 year postsurgery from 2009 to 2013 (N=44). INTERVE...
