OBJECTIVES/HYPOTHESIS To evaluate whether there is a genetic contribution to the development of narrow bony cochlear nerve canal and analyze the differences between unilateral and bilateral narrow bony cochlear nerve canal. STUDY DESIGN Retrospective review. METHODS Patients diagnosed with unilateral (n=44) or bilateral (n=13) sensorineural hearing loss with narrow bony cochlear nerve canal...

background : glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. this study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. methods : the study was a cross-sectional study evaluating patients with unstable shoulder...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...

abstract  background: spondylolysis and spondylolisthesis can be associated with significant  low back pain, especially in physically active adolescents. non-operative management  is usually successful in improving symptoms, but surgical intervention is  occasionally required. the aim of this study was to determine the effect of in situ posterolateral  fusion in the treatment of refractory case...

Kinematic analysis for in vivo assessment of elbow endoprostheses requires knowledge of the exact positions of motion axes relative to bony landmarks or the prosthesis. A prosthesis-based reference system is required for comparison between individuals and studies. The primary aim of this study was to further develop an earlier described algorithm for fusion of radiostereometric analysis (RSA) d...

THE JOURNAL OF BONE AND JOINT SURGERY tions, including 24-hour ambulant monitoring, revealed only atrial fibrillation. Radiographs of the cervical spine showed spondylolisthesis at the C5 to C6 level. Anterior cervical interbody fusion was performed at this level; the bony changes seen at operation were similar to those described in case 1. He had no more drop attacks during the last year of hi...

Stem cells biology is one of the most frequent topic of physiological research of today. Spinal fusion represents common bone biology challenge. It is the indicator of osteoinduction and new bone formation on ectopic model. The purpose of this study was to establish a simple model of spinal fusion based on a rat model including verification of the possible use of titanium microplates with hydro...
