Arthroscopic rotator cuff repair is one of the most painful surgical procedures; patients complain pain especially during first 48 hours postoperatively. Pain management an essential goal to reduce demand for analgesic agents and patient discomfort. Various methods have been introduced arthroscopic repair, including continuous arthroscopy-guided suprascapular nerve blocks (SSNB) interscalene bl...

The aim of this paper is to study how efficiently we evaluate a system of multivariate polynomials and their partial derivatives in homotopy continuation methods. Our major tool is an extension of the Horner scheme, which is popular in evaluating a univariate polynomial, to a multivariate polynomial. But the extension is not unique, and there are many Horner factorizations of a given multivaria...
