Maxon is an excellent suture material very similar in degradation curve to PDS-II and should never had degraded that fast. It however, is very susceptible to damage as are most monofilament synthetics. A possibility would be that someone grasped part of the suture with a forceps or clamp which could definitely have caused a fracture and subsequent failure. One should never touch any part of the suture that will be left in situ with an instrument other than the human hand.

If the operating surgeon is sure that such an occurrence did not happen, the manufacturer should be notified. I used maxon extensively in residency for gyn onco cases and never saw a single failure and the strength profile is far beyond what you describe. I use PDS-II now because of local availability.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
