Torque resistance after fixation of Jones fractures with intramedullary screws.

Background: Intramedullary screws frequently are used for fixation of Jones fractures of the fifth metarsal. While the ability of intramedullary screw fixation in fifth metatarsals to resist bending and tensile forces is well known, the ability to withstand torsion has not been studied. This paper compares the torsional stiffness of Jones fractures treated with 6.

Avascular necrosis of the talus: current treatment options.

AVN of the talus is a challenging disease process with respect to patho-physiology and treatment. We believe that our algorithm is a legitimate approach to aid the orthopedic surgeon in initiating a promising treatment. It is divided into different levels and allows to change between some.

Potential donor rotational bone grafts using vascular territories in the foot and ankle.

Background: An improved understanding of the extraosseous and intraosseous blood supply of the distal aspect of the tibia, distal aspect of the fibula, cuboid, and cuneiforms should identify vascular territories that would enable surgeons to perform rotational vascularized pedicle bone-grafting procedures in the foot and ankle.

Methods: We investigated the blood supply of twenty cadaveric lower extremities using two vascular injection techniques. In order to define the extraosseous and intraosseous arterial anatomy in this region, ten specimens were sequentially subjected to injection with Batson's compound, soft-tissue digestion, and bone-clearing according to a modified Spalteholz technique.
