Dysfunction of the tibialis posterior tendon evolves through a series of stages. The pain symptoms, clinical signs, and roentgenographic changes for each of these stages are characteristic. This staging system permits clarification and individualization of dysfunction, expected pathologic changes, and surgical treatment. The importance of the tibialis posterior tendon in normal hindfoot functio...

BACKGROUND The tibialis posterior muscle is believed to play a key role in controlling foot mechanics during the stance phase of gait. However, an experiment involving localised tibialis posterior muscle fatigue, and analysis of discrete rearfoot and forefoot kinematic variables, indicated that reduced force output of the tibialis posterior muscle did not alter rearfoot and forefoot motion duri...

The purpose of this study was to examine differences in gait mechanics between patients with acute stage II PTTD and healthy volunteers. Hindfoot and midfoot kinematics, plantar foot pressures and electromyographic (EMG) activity of the posterior tibialis, gastrocnemius, anterior tibialis and the peroneals were measured in five patients with acute stage II PTTD. Kinematics and kinetics were com...

This study assessed if transfer of the extensor hallucis longus is a valid alternative treatment to split transfer of the tibialis anterior tendon in adult hemiplegic patients without overactivity of the tibialis anterior. One group of 15 patients had overactivity of tibialis anterior in the swing phase, and underwent the split transfer. A further group of 14 patients had no overactivity of tib...

BACKGROUND Most tissue banks recover and irradiate tibialis tendon allografts from donors aged up to 65 years. It is unknown whether donor age and low-dose gamma irradiation affect the initial biomechanical properties of tibialis allografts. HYPOTHESIS Donor age up to 65 years and low-dose gamma irradiation do not significantly affect the initial biomechanical properties of tibialis allograft...

Reports of traumatic injury to the anterior lower leg muscles are scarce, with only a handful of reports of traumatic injury to the tibialis anterior. A database search of Medline, Cinhal, and Sports Discus only revealed three such cases, and they did not result from a direct sporting injury. This report documents the case of a traumatic rupture of tibialis anterior muscle in a young female Gae...

a pseudo aneurysm results from leakage of blood from an artery after trauma or dehiscence or separation of a surgical anastomosis. the reported rate of pseudo aneurysm in access sites range from 0.88% to 8%. it has some cause like penetrating trauma, blunt trauma and endovascular procedure. the differential diagnoses of this lesion are hematoma, av fistula, lymphadenopathy, lymphocele, dvt, com...

background: the transfer of the tibialis posterior tendon to the dorsum of foot can restore the function of the paralyzed dorsiflexor muscles of the foot and ankle. in order to reduce the wound complication in the insertion site of tendon to bone by a plantar knop we used a new method of fixation by an absorbable screw inserted dorsally. methods: we performed this operation on 15 patients in a ...

This article presents a novel technique for repair of chronic tibialis anterior tendon ruptures. All chronic tibialis anterior tendon ruptures reviewed were treated with this technique. Patients with chronic tibialis anterior tendon ruptures presenting to the authors' institution from 2006 to 2012 had preoperative and postoperative Foot and Ankle Ability Measure scores. The average follow-up ti...

NERVE TRANSFERS FOR TIBIALIS ANTERIOR MUSCLE PARALYSIS (FOOT DROP) A HUMAN CADAVER-BASED FEASIBILITY STUDY The following abstract was presented at William Beaumont Army Medical Center’s Research Day in May 2008. Purpose: This study explored the anatomic feasibility of using an interosseous nerve transfer to restore motor function to the tibialis anterior muscle following injury to the common pe...
