Shoulder Arthroscopy - Subacromial Bursectomy:
- Surgical Considerations:
arthroscopic rotator cuff repair
- note that the
is an anterior structure;
- it is located from anterior 1/2 to 1/3 of acromion to just medial to A-C joint to 1 to 2 cm anterior to acromion & 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;
- when introducing instruments into the subacromial bursa, use the blunt trochar sheath is lyse adhesions from the undersurface of
the acromion and the lateral part of the deltoid;
- elements of bursectomy:
- needs to be compulsive and complete for appropriate visualization;
- there needs to be complete removal down to the subdeltoid space;
- there should be complete visualization 1 cm medial to both the anterior and posterior arthroscopic portals;
- OR descriptions bursal proliferation and inflammation, hemorrhaging in
, hypertrophy and fraying of CA
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;
