Some forms of acupuncture involve the deliberate placement of "permanent" silver or gold needles into the patient. These are typically ~1 cm in length and at one time may have been needles broken off deliberately but more recently involve the injection of short needles using a spring-loaded syringe. Though they are intended to remain subcutaneous, reports of migration into the abdomen and chest are present with resulting complications.
