The sensory branch distribution of the suprascapular nerve: an anatomic study.
The suprascapular nerve is responsible for most of the sensory innervation to the shoulder joint and is potentially at risk during surgery. In this study, 31 shoulders in 22 cadavers were dissected to investigate the sensory innervation of the shoulder joint by the suprascapular nerve, with special reference to its sensory branches. ⋯ In 74.2% of the shoulders, an acromial branch was also found, originating just proximal to the scapular neck, running to the infraspinatus tendon. These cadaveric results indicate that sensory branches to the shoulder joint are more common and numerous than previously described and therefore should be considered in shoulder surgery and nerve blocks to this area.

Pulsed radiofrequency applied to the suprascapular nerve in painful cuff tear arthropathy.
The purpose of this study was to assess the efficacy of pulsed radiofrequency (PRF) applied to the suprascapular nerve for pain relief in medically unfit patients with painful cuff tear arthropathy. Twelve patients with chronic shoulder pain due to cuff tear arthropathy were recruited. The mean age was 68 years (range, 60-83 years). ⋯ Ten patients showed improvement in the VAS score (P = .24) and Constant score (P = .005) and eleven in the Oxford score (P = .001). There was a deterioration in the VAS scores between 3 and 6 months, suggesting that the benefits were starting to wear off with time (P > .05). We conclude that PRF may be a useful therapeutic adjunct in patients with painful, end-stage rotator cuff tear arthropathy who are medically unfit for surgery.

Beach chair position with instrumental distraction for arthroscopic and open shoulder surgeries.
Arthroscopy is widely used in the diagnosis and treatment of shoulder disorders. It can be performed in the lateral or sitting position (beach chair). Both have advantages and disadvantages. ⋯ We have also not had difficulty visualizing or approaching the glenohumeral and subacromial spaces in the treatment of shoulder disorders. It is a safe, practical, easy, and fast set up. Its versatility makes it particularly helpful for the less experienced arthroscopic surgeon.

Randomized Controlled TrialExtracorporeal shock wave therapy for calcifying tendinitis of the shoulder.
We prospectively studied extracorporeal shock wave therapy (ESWT) for calcific tendinitis of the shoulder in 46 consecutive patients. All patients were randomly divided into 2 groups: treatment and control. The 33 patients in the treatment group received 2 courses of ESWT at the energy density of 0.55 mJ/mm(2) (1000 impulses). ⋯ In contrast, elimination was partial in 2 control patients (15.3%) and unchanged in 11 (84.7%). There was no significant difference between Gärtner type I and type II groups in the Constant score (P > .05). ESWT shows promise for pain relief and functional restoration of calcific tendinitis with negligible complications.

The anatomy of the quadrilateral space with reference to quadrilateral space syndrome.
Quadrilateral space syndrome is a rare condition in which the contents of the quadrilateral space, the axillary nerve and the posterior circumflex humeral artery, are compressed, leading to vague symptoms of shoulder pain, tenderness over the quadrilateral space on palpation, and teres minor and deltoid denervation. Fibrous bands within the quadrilateral space are often cited in the literature as a cause of compression in quadrilateral space syndrome; however, Cahill and Palmer did not see these bands in cadaveric dissection. These are postulated to cause compression of the quadrilateral space contents in abduction and external rotation of the shoulder. ⋯ Dissection revealed that fibrous bands are a common finding in the quadrilateral space, being present in 14 of 16 shoulders. The most common site for a fibrous band was between the teres major and the long head of the triceps. Where the bands were present, both internal and external rotation of the shoulder caused a reduction in the cross-sectional area of the quadrilateral space.
