“…The clavicular and acromial parts are innervated by the abAN, as was found in almost all specimens in the present study, but the spinal part, as confirmed by Uz et al [39], may either be innervated only by the pbAN, or may have double innervation by the abAN and pbAN. Uz et al [39] note such double innervation in 30% of cases. In our study, double innervation of the spinal part was found in a larger percentage of cases: 12 limbs out of 17.…”

“…Even though variations of the AN have been subject of a lot of research [2,4,7,13,32,39], there are few studies of the detailed scheme of DM innervation [4,39]. Anatomical variations of innervation of individual parts of the DM are clinically relevant.…”

“…In our study, double innervation of the spinal part was found in a larger percentage of cases: 12 limbs out of 17. Such variations may be clinically significant, taking into account different surgical approaches, as well as transfer of the DM spinal part to the long head of the triceps, which is sometimes performed [10,14,39]. The spinal part of the DM contributes up to 20% to arm extension (Crouch et al [10]).…”

Background:The deltoid muscle (DM) anterior fibres) and by pbAN (posterior fibres), and variation II, in which the spinal part did not have double innervation -the abAN innervation area covered only the acromial and clavicular parts, and the entire spinal part was supplied by pbAN. Both variations had a segmented arrangement of sub-branches reaching individual parts of the DM, which was particularly distinct in the clavicular Conclusions:The study confirmed the existence of a characteristic segmented innervation scheme of the DM which corresponds with the segmented morphology of its individual parts. An analysis of the internal structure of the muscle specific architectonics based on the tendon system was also presented. (Folia Morphol 2014; 73, 2: 216-223)

“…In the present study, its incidence is 18% which is within the range. The mean distance of origin of axillary nerve from the anteromedial aspect of tip of coracoid process and posterolateral aspect of acromion process of different studies [3,[9][10][11] is compared with present study and is summarized in Tab 3. Ozgur Cetik et al [12], studied the distance of origin of axillary nerve from the acromion and its relation to arm length, and identified a safe area above the axillary nerve which is quadrangular in shape, with the length of the lateral edges being dependent on the individual's arm length.…”

Background: Axillary nerve, one of the terminal branches of posterior cord of brachial plexus is more prone for iatrogenic injuries. Lack of proper anatomical knowledge and variations of axillary nerve leads to an increased risk of nerve injuries. The present study describes the origin of axillary nerve, its distance of origin from anteromedial aspect of coracoid process, posterolateral aspect of acromion process, and its termination.

“…Along its course across the subscapular muscle, the AN releases its first articular branch, which slowly separates itself from the main stem as it runs to the inferior-anterior joint capsule. 19 According to Uno et al the AN stayed in the middle third of the "capsular hammock" between the glenoid and humeral neck and it has an intimate relation with the shoulder capsule between the 5 and 7 o'clock (right shoulder) positions. 20 Eakin et al reported that the nerve was closest to the glenoid at the 4:30 O'clock position.…”

Background: To evaluate analgesic efficacy when catheters are positioned with assistance of arthroscope to block suprascapular and axillary nerves in patients undergoing arthroscopic repair of rotator cuff under general anesthesia.Methods: Present study was performed at department of orthopedics, Gujarat Adani Institute of Medical Science, Bhuj, Kutch, Gujarat. 24 patients who experienced arthroscopic repair of rotator cuff between July 2015 and October 2015 were catheterized to block suprascapular and axillary nerves through shoulder arthroscopy were incorporated in the study. Clinical outcomes were assessed using visual analog scale (VAS) scores preoperatively and at 0 h, 6 h, 12 h, 18 h, 24 h, and postoperative day 2.Results: Preoperative and postoperative 0 h, 6 h, 12 h, 18 h, 24 h, and day 2 mean VAS scores were 6.37±0.91, 0.45±0.39, 0.59±0.40, 0.62±0.39, 0.61±0.42, 0.51±0.35, and 1.54±0.50, respectively. No statistical difference was found among 0 h, 6 h, 12 h, 18 h, and 24 h time points; however, assessment of postoperative day 2 and postoperative 0 h, 6 h, 12 h, 18h and 24 h VAS scores showed statistically significant difference (P <0.05). All patients were discharged at the end of 24 h with no complication. The mean time (in minutes) required for blocking suprascapular nerve and axillar nerve were 14.38±3.21 and 3.75±0.85, respectively. Conclusions: These results confirmed that blocking two nerves with arthroscopic approach was an excellent pain management method in postoperative period. Accordingly, patients could recover rapidly and patients’ satisfaction could be improved.
