Decompression of the suprascapular nerve at the suprascapular notch under combined arthroscopic and ultrasound guidance

Abstract Decompression of the suprascapular nerve (SSNe) at the suprascapular notch (SSNo) is usually performed with an arthroscopic procedure. This technique is well described but locating the nerve is complex because it is deeply buried and surrounded by soft tissue. We propose to combine ultrasou...
