Shoulder Arthroscopy - Subacromial Bursectomy:
arthroscopic rotator cuff repair
- basic science:
Vascular endothelial growth factor 121 and 165 in the subacromial bursa are involved in shoulder joint contracture in type II diabetics with rotator cuff disease.
The molecular pathophysiology of subacromial bursitis in rotator cuff disease
Proinflammatory cytokines and metalloproteases are expressed in the subacromial bursa in patients with rotator cuff disease
Stromal cell-derived factor 1 (SDF-1, CXCL12) is increased in subacromial bursitis and downregulated by steroid and nonsteroidal anti-inflammatory agents.
Increased IL-1beta expression and myofibroblast recruitment in subacromial bursa is associated with rotator cuff lesions with shoulder stiffness.

- Surgical Considerations:
- note that the
is an anterior structure;
- it is located from the anterior one half to one third of the acromion to just medial to A-C joint to 1 to 2 cm anterior to acromion and 2.5 cm laterally;
- posterior busrsal wall is thick posteriorly (called posterior bursal curtain)
- this posterior bursal curtain frequently “closes” as the scope is backed posteriorly to get a larger field;
- it may be necessary to resect a portion of this structure to visualize the entire arch;
- technical considerations (see

ligament, acromial spur formation;
- bursa is sometimes debrided after the acromioplasty, since it tends to bleed more (disrupting the case);
- take special when debriding around the AC joint since bleeding is especially troublesome;
- rotate the arm internally and externally to expose different parts of the bursa;
- downward traction generally increases the working space available
for the subacromial space.
- use of a radiofrequency device before a motorized shaver is used for bursectomy can help to minimize bleeding;
- methodically sweep the shaver along the bursa;
