BACKGROUND The goal of this study was to compare simple radiographic findings and clinical results according to residual ulnar variance following ulnar shortening for ulnar impaction syndrome. METHODS Forty-five cases of ulnar impaction syndrome, which were treated with ulnar shortening from 2005 to 2008, were studied retrospectively. Group I included 13 cases with positive residual variance ...

BACKGROUND Electrodiagnostically, localization of ulnar nerve lesions, which commonly occurs at the elbow, is sometimes problematic. Measurement of motor ulnar nerve conduction velocity (NCV) at the elbow is amongst the most popular techniques to diagnose ulnar neuropathy. In this method, recording from the first dorsal interosseous muscle (FDI) is suggested to be more sensitive than the abduct...

OBJECTIVE The present study's aim was to analyze the late responses' parameters in order to determine the utility of each one. METHODS The study, conducted on a total of 325 patients with entrapment neuropathy of the median nerve and 36 with entrapment neuropathy of the ulnar nerve, included the bilateral evaluation of the median and the ulnar nerve and analysis of 20 F-wave and 4 A-wave para...

Ulnar neuropathy at the wrist is rarely reported as complications of carpal tunnel release. Since it can sometimes be confused with recurrent median neuropathy at the wrist or ulnar neuropathy at the elbow, an electrodiagnostic study is useful for detecting the lesion in detail. We present a case of a 51-year-old woman with a two-week history of right ulnar palm and 5(th) digit tingling sensati...

Introduction Fractures of the ulnar styloid frequently accompany fractures of the distal radius, however, there is no conclusive evidence whether it influences the final outcome of the treatment. The majority of studies show no negative effect of ulnar styloid fractures on final outcome, when the fracture of the distal radius is fixed, preferably by a locking plate [1,2]. Some authors, however,...

The authors reviewed a 10-year consecutive series of ulnar-shortening osteotomies using a freehand, single oblique cut with 2 or 3 stacked saw blades. Twenty-one patients (23 wrists) with chronic ulnar impaction syndrome (mean age, 45 years; range, 16 to 73 years) demonstrated an average preoperative ulnar variance of +2.1 mm (range, 0.0 to 4.0 mm). An oblique osteotomy was performed in the dis...

In situ ulnar nerve release has been gaining popularity as a simple, effective, and low-morbidity procedure for the treatment of cubital tunnel syndrome. One concern with the technique is how to manage the unstable ulnar nerve after release. It is unclear how much nerve subluxation will lead to problems and surprisingly there is no grading system to assess ulnar nerve instability. I propose suc...

MEDIAN nerve compression at the wrist is common and its treatment by decompression is usually successful. Ulnar nerve entrapment, on the other hand, is uncommon. The ulnar nerve as it enters the hand passes through and divides in the canal of Guyon, into its deep (motor) and superficial (sensory) branch. This ulnarcarpal tunnel is bounded proximally and medially by the pisiform, distally and la...

background: to evaluate the intermediate-term outcomes of radius shortening as a treatment for kienbock’s disease. materials and methods: in a historical cohort, 16 skeletally mature patients (9 men and 7 women) with kienbock disease, who were treated with radial shortening osteotomy between 2002 and 2012, were reviewed in our study. the mean age of our patients was 30 (range 18-43) years old. ...
