As reported: "simplex was used for the operation of the artificial scapular head.Cement was inserted into a cement gun using a humeral nozzle, but it hardened in about 3 minutes.Because hardening was quick at the time of inserting the stem, the surgeon hit it with a hammer and inserted it, and then the patient¿s bone broke.The cement was delivered to the operation room from central (b)(4) medical link on july 22 and kept refrigerated until the day of the operation.I took it out of the refrigerator 5-10 minutes before using the cement.The chief of the operating room requested that the cement was cured quickly and that there was no problem with the product.".
