Patients who receive the lateral and sagittal infraclavicular block (LSIB) tend to supinate their hand and forearm which may hamper optimal positioning for surgery of the dorsal side of the hand. The investigators think that this supination is caused by lateral rotation in the shoulder. The main lateral rotator of the shoulder is the infraspinatus muscle, which is innervated by the suprascapular nerve (SSN).The investigators hypothesized that optimal positioning of the hand for surgery on the dorsal side of the hand may be achieved by performing a SSN block (SSNB) in addition to the LSIB.
According to the hypothesis the investigators will perform a double blind , placebo controlled study to answer the research question above.
