The author reports a case of a fractured medial malleolus with a completely disrupted deltoid ligament following a pronation injury. To the author's knowledge, concurrent failure of both structures over the medial side of the ankle has not been previously documented in a pronatory injury.

The supracondylar process is a beak-like bony projection that arises from the anteromedial surface of the humerus. The process has rarely been associated with compression of the median nerve and seldom requires treatment. We report a case of a supracondylar process that caused tenting of the median nerve with elbow extension and pronation.

A rare case of an isolated traumatic palmar dislocation of the distal radioulnar joint is presented. Clinically, there is a loss of pronation and supination. The dislocation was treated using an open reduction, reinsertion of the capsule-ligamentous complex and temporary stabilization using K-wires.

Many of the major locomotor transitions during the evolution of Archosauria, the lineage including crocodiles and birds as well as extinct Dinosauria, were shifts from quadrupedalism to bipedalism (and vice versa). Those occurred within a continuum between more sprawling and erect modes of locomotion and involved drastic changes of limb anatomy and function in several lineages, including saurop...

INTRODUCTION Dislocation of the radial head, congenital or traumatic, anteriorly, posteriorly or laterally displaced, requires surgery to reseat and stabilize the head of the radius within the joint, in order to restore elbow flexion and, as much as possible, pronation-supination. SCOPE This article is meant to present the technique of proximal radial-ulnar ligament plasty using the extensor ...

Background: Carpal tunnel syndrome (CTS) is characterized by complications such as pain, paresthesia, andnumbness in the fingers. There are some surgical therapies for the management of severe carpal tunnel, but differencesexist between the treatments available for creating the opposition. The current study was conducted to compare theeffect of modified Camitz and BRAND techni...

When humans rotate their wrist in flexion-extension, radial-ulnar deviation, and combinations, the resulting paths (like the path of a laser pointer on a screen) exhibit a distinctive pattern of curvature. In this report we show that the passive stiffness of the wrist is sufficient to account for this pattern. Simulating the dynamics of wrist rotations using a demonstrably realistic model under...

The authors report this case of a 48-year-old male patient sustaining a complete tear of the biceps tendon and associated radial head subluxation. A restriction of supination-pronation of the forearm was noted as a result of the radial head subluxation. The complete tear of the biceps tendon was treated conservatively and the radial head subluxation corrected itself.
