Periostitis blade of a horned dinosaur. Periostitis Periostitis, also known as periostalgia, is a medical condition caused by inflammation of the periosteum, a layer of connective tissue that surrounds bone. The condition is generally chronic, and is marked by tenderness and swelling of the bone and pain. Acute periostitis is due to infection, is characterized by diffuse formation of pus, severe pain, constitutional symptoms, and usually results in necrosis. It can be caused by excessive physical activity as well, as in the case of medial tibial stress syndrome (also referred to as tibial periostalgia, soleus periostalgia, or shin splints).

Percutaneous tibial nerve stimulation review that looked at mostly low quality studies found tentative evidence of benefit. A more recent high quality study however did not find benefit in fecal incontinence. A patient sits comfortably with the treatment leg elevated. A fine needle electrode is inserted into the lower, inner aspect of the leg, slightly cephalad/rostral to the medial malleolus. As the goal is to send stimulation through the tibial nerve, it is important to have the needle electrode near (but not on) the tibial nerve. A surface electrode (grounding pad) is placed over the medial aspect of the calcaneus on the same leg.
