Arthroscopic subacromial decompression (ASAD) is becoming a widely performed surgical procedure of the shoulder. The technique has evolved from open anterior acromioplasty as described by Neer,1,2 Hawkins et al,3,4 Rockwood,5 and Bigliani et al.6 The transition from open to arthroscopic technique entails a definite learning curve and should not be underestimated. This chapter focuses on the tec...

Background Arthroscopic stabilization is the most broadly used surgical procedure in the United States for management of recurrent shoulder instability. Latarjet coracoid transfer has been considered a salvage surgical procedure for failed arthroscopic repairs or cases of significant glenoid bone loss; however, with recent literature suggesting reduced risk of recurrent instability with Latarje...

OBJECTIVE To evaluate the safety of arthroscopic Latarjet procedure in cadavers. METHODS : Twelve cadaveric shoulders underwent arthroscopic Latarjet procedure in our laboratory for arthroscopy, by four different surgeons. Following surgery, the specimens were subjected to radiographic examination and evaluated by an independent examiner. Nineteen parameters were evaluated, including the cora...

Surgical simulation offers a solution to the problems of reduced training time and surgical exposure by allowing trainees develop skills outside operating room in safe, cost-effective environment. We developed highly detailed, procedure-specific shoulder arthroscopy simulator using 3-dimesional printing with aim providing greater access support trainees.

The aim of this study was to review all cases of pseudoaneurysm in the literature, in predominantly arthroscopic procedures on the knee, and to report on a case of pseudoaneurysm that we treated. A bibliographic search was conducted for scientific articles published in Brazilian and foreign periodicals over the last 23 years. Forty-seven cases were found, in 40 articles. In addition to these 47...

BACKGROUND Optimal surgical management of anterior shoulder instability remains controversial. There is a need to assess the most recent trends for primary and revision shoulder stabilization surgery using a national database significantly larger than those previously utilized. HYPOTHESIS Most shoulder stabilization procedures are performed arthroscopically. Examining revision procedures, we ...

In this paper a novel region-merging image segmentation approach is presented. This approach is based on a two-step procedure: a distance metric is learned from some features on the image, then a piecewise approximation function for the Mumford-Shah model is optimized by this metric. The global optimum of the approximation function is inductively achieved under high polynomial terms of the Maha...
