Infection, neurovascular injury, and other general complications are rare after shoulder instability surgery. The precise incidence depends on the specific procedure performed but, in general, the transition from open to arthroscopic Bankart repair has lowered the complications rate. The Latarjet procedure seems to be slightly riskier regarding the above-mentioned complications. Nerve injuries develop in relation to direct nerve injury, due to improper positioning or traction, or in relation with the anesthetic procedure. A careful postoperative neurological assessment is necessary to identify these injuries soon and define the etiology, this will guide further management. Infection is specially challenging as diagnosis can often be difficult and the success of treatment is time sensitive. A diagnostic work-up, including blood tests and imaging can help distinguish between a rocky postoperative course and a deep infection, and the threshold to perform those should be low. If deep infection is suspected, surgical treatment should be considered immediately and the antibiotic treatment, started after proper sampling of the infected tissue, should be based in the habitual flora present in these infections. General complications such as thromboembolic or cerebrovascular events and hypothermia can also develop in shoulder instability subjects. For these problems, the focus should be placed on prevention.
