STUDY DESIGN: Retrospective review of a large series of patients who underwent spinal surgery at a single institution during a 10-year period. OBJECTIVES: To further clarify the frequency of incidental durotomy during spine surgery, its treatment, associated complications, and results of long-term clinical follow-up.SUMMARY OF BACKGROUND DATA: Incidental durotomy is a relatively common occurrence during spinal surgery.ncidental durotomy occurred at the time of surgery in 66 patients (3.1% overall incidence). Incidence varied according to the specific procedure performed but was highest in the group that underwent revision surgery.
Dirty thermocouple: If you can light your pilot light, but the water heater pilot keeps going out, there are many possible causes. One of them is a dirty thermocouple. When you have a problem with your water heater not lighting, look at your water heater pilot light. Inspect the thermocouple to determine if it is dirty.
Gas water heaters also have a Vacation setting, which keeps the pilot light on but doesn't heat the water, so you save money on your gas bill when you aren't at home. Turn the gas water heater temperature down to Vacation before you leave, and turn it back up to normal heat when you get back.f you play with different heat settings, you can find a water heat setting on your gas water heater that works for all your needs. If you turn it down too low and you have a dish washer, it may have trouble cleaning the dishes properly because the water isn't hot enough.
