Shoulder arthroscopy


shoulder arthroscopy
Shoulder arthroscopy is an endoscopic way to take a look into the shoulder joint and also to operate on shoulder problems: "the view through a keyhole". The physician looks into the shoulder joint using a 0.5 to 1 cm skin incision, placing a camera through it into the shoulder and viewing the pictures on a TV or flat screen. To see a shoulder arthroscopy, just press the play button above.
A shoulder arthroscopy is an operative procedure which is performed in regional or general anaesthesia. Several skin incision about o.5 to 1 cm are created and the camera, as well as the instruments, are changed for this endoscopic operative procedure. Sometimes working cannulas are placed within these skin incisions. This sounds quite easy, but it is challenging, sometimes.
Why is it still necessary to take a look into the shoulder joint, when modern diagnostics like computed tomography or MRI are available, today?
1. MRI and CT are very good, but they have a natural boundary in resolution. Fine damaged structures within the joint can not always be detected, because those damaged structures are to narrow to each other or they are just to small to be displayed with modern imaging techniques.
2. A lot of shoulder problems are dynamic ones, which means that shoulder pain and the original problem occur during movement and not while the shoulder joint is resting. MRI and CT are static procedures, which can not display these dynamic problems.
3. Shoulder injuries and diseases can be treated in combination with an arthroscopy. First the appraisal is done and then the arthroscopic operative procedure follows, all within the same endoscopic operation. Therapy is combined with diagnosics.
Acromioplasty, the removal of bone at the "roof of the shoulder" in patients with an impingement syndrome, is performed arthroscopically as a routine procedure.
Shoulder instabilities after trauma and dislocations as well as multidirectional instabilities are operated on an endoscopic basis quite often. Suture anchors are used to stabilize the unstable shoulder.
Other indications are the arthroscopic removal of calcium deposits in patients suffering from a calcific tendinitis. And also rotator cuff tears are routinelly closed arthroscopically.
In frozen shoulder, arthroscopy of the shoulder joint is used additionally to split the capsule. Even if shoulder pain and problems remain unclear for several month or sometimes for years, shoulder arthroscopy is performed for diagnostic purposes.
Shoulder arthroscopy is performed in a beach chair position or with the patient lying at the side in a lateral position. The arthroscopic appraisal takes about 3 to 8 minutes. The arthroscopic shoulder operation is done afterwards within one operation. Operation time over all takes - for most procedures - between 20 minutes to 1 hour.
