Dear Editor, Anterior transposition of the inferior oblique (IO) muscle is an effective treatment for dissociative vertical deviation (DVD) when associated with IO muscle overaction [1]. By transposing the insertion of the IO muscle anterior to the equator, a force vector of the IO muscle converts from elevation to depression, which in turn reduces DVD [1]. After the procedure, the superior rec...

Ulnar nerve neuropathy at the elbow represents the second most frequent compression neuropathy of the upper extremity. Of the five different anatomical areas responsible for ulnar nerve compression at the elbow region, the epitrochlear-olecranon channel and Osborne’s arcade are the most common. An additional cause of nerve damage is a dynamic process in which the ulnar nerve dislocates anterior...

Background: The procedure of choice in the surgical treatment of cubital tunnel syndrome remains controversial. The aim of this study is to report the results of simple decompression and decompression with anterior subcutaneous transposition. Methods: A retrospective review (July 2002–January 2007) using the Bishop Score to assess outcome. A total of 102 procedures (91 patients, 11 bilateral) w...

PURPOSE Simple decompression of the ulnar nerve has outcomes similar to anterior transposition for cubital tunnel syndrome; however, there is no consensus on the proper technique for patients with an unstable ulnar nerve. We hypothesized that 1) simple decompression or anterior ulnar nerve transposition, depending on nerve stability, would be effective for cubital tunnel syndrome and that 2) th...

PURPOSE The purpose of this study is to compare the magnitude and axis of astigmatism induced by a combined inferior oblique (IO) anterior transposition procedure with lateral rectus (LR) recession versus LR recession alone. METHODS Forty-six patients were retrospectively analyzed. The subjects were divided into two groups: those having concurrent inferior oblique muscle overaction (IOOA) and...
