Answer

To avoid puncture of tendons, blood vessels, and nerves, the clinician performing the procedure should be familiar with the anatomy of the specific joint. The risk of such injuries can be minimized by using the extensor surface of the joint for needle insertion while keeping the joint in minimal flexion.
