Nerves crossing a joint supply:

  • Muscle
  • Skin
  • Joint

This is a reminder that whenever doing any examination of a joint, you must consider any nerves that are crossing that joint, and what they supply. Especially important for situations such as a dislocated shoulder, where you must test sensation over the deltoid to see if the axillary nerve has been damaged prior to relocating the shoulder, or you could have a sizeable lawsuit in your lap.
