The author observed a new accessory bone of the foot in the distal portion of navicular, which articulated with the medial cuneiform and the intermediate cuneiform, and named it os infranaviculare. A degenerative change was observed between the accessory bone and the navicular; this caused midfoot pain to the patient during weight-bearing. Thus, the patient was treated by excision of the access...

Mueller-Weiss syndrome is a rare entity related to adult-onset spontaneous osteonecrosis of the navicular. It is a painful and debilitating illness, which is more frequent in women and can be either unilateral or bilateral. It was first described by Walther Mueller in 1927, who believed this condition was due to chronic compression of the navicular from the adjacent bones. In 1929, Konrad Weiss...

     Purpose: The purpose of this study was to investigate the effects of specialized Kyokushin Karate exercises on the activity of leg muscles and the height of the medial longitudinal arch in adolescent girls with foot pronation.    Methods: This study recruited twenty-four adolescent girls with foot pronation who voluntarily agreed to participate and were randomly assigned to either a train...

In the adult a painful rigid flat foot with a calcaneo-navicular bar usually requires treatment by triple arthrodesis. In the adolescent also, long-standing deformity or adaptive joint changes may call for triple arthrodesis to alleviate pain. In the younger patient, however, without adaptivejoint changes, it is worth considering simple excision ofthe calcaneo-navicular bar. This has been pract...

BACKGROUND The prevalence of flexible flatfoot is high among preschool-aged children, but the effects of treatment are inconclusive due to the unclear definitions of normal flatfoot. To date, a universally accepted evaluation method of the foot arch in children has not been completely established. Our aims of this study were to establish a new method to evaluate the foot arch from a three dimen...

Navicular bones from the 4 limbs of 95 horses, classified in 9 categories, were studied. The anatomical bases were established for the morphometry of the navicular bone and its variations according to the category of horse, after corrections were made for front or rear limb, sex, weight, size and age. In ponies, navicular bone measurements were smallest for light ponies and regularly increased ...

OBJECTIVES Tibialis posterior tendon transfer (TPT) technique, using either the Circum-tibial (CT) or Inter-osseus (IO) route is the standard surgical technique to correct foot drop. The selection of the route of transfer is usually dependent on the surgeon's preference. This study aims to identify criteria to help make that selection. SUBJECTS AND METHODS A study was carried out on 381 feet ...

UNLABELLED An absolutely convincing technique of anterior transfer of the tibialis posterior (TP) tendon for treating drop foot has not been developed. Thirty-seven consecutive adult patients with drop foot owing to deep peroneal nerve injury were treated with bone-to-bone TP tendon transfer. The TP tendon with a small bony attachment was procured from the undersurface of the navicula and then ...

INTRODUCTION Osteoarthritis of the talonavicular joint caused by inflammatory, degenerative, and post-traumatic arthritis has been commonly described, and isolated arthrodesis for talonavicular joint has usually been performed for such conditions. However, arthritis accompanied by pseudarthrosis of the navicular bone is an extremely rare case, and to the best of our knowledge, isolated arthrode...
