Cricothyrotomy is an important surgical technique. We studied the anatomy of the cricothyroid membrane in 13 adult fresh cadavers preserved at 45 degrees F and examined at 70 degrees F. The working dimensions of the cricothyroid membrane were measured for emergency cricothyrotomy and placement of an airway tube. ⋯ Eight subjects (62%) had an artery delineated transversely across the cricothyroid membrane. Two subjects (15%) had sclerosis of the cricothyroid joint. To promote the safe use of cricothyrotomy, the anatomy of the cricothyroid membrane is defined and clinically relevant data are presented.

The risks of occupational radiation exposure for orthopaedic surgeons has not been well documented. The use of fluoroscopy in orthopaedics has reduced morbidity and by reducing operative time and by reducing the invasiveness of procedures. Increasingly procedures requiring the use of fluoroscopy are being developed. ⋯ The exposure levels are well below the maximum dose limits for ionizing radiation as recommended by European Economic Communities EURATOM directives. Experimentally using a phantom patient it was shown that the exposure to ionizing radiation during the insertion of a dynamic hip screw was minimal. Despite the low level of exposure care should be exercised when using fluoroscopy.
