It's kind of hard to say which model is most reliable. Taken care of properly, they'll all hold true. But there are some models more prone to certain things (subframe, etc) than others, but again, the main thing is how well it was looked after by the person before you.
obÂ·tuÂ·raÂ·tor forÂ·aÂ·men. A large, oval or irregularly triangular aperture in the hip bone, the margins of which are formed by the pubis and the ischium; it is closed by the obturator membrane, except for a small opening for the passage of the obturator vessels and nerve. Synonym(s): foramen obturatum [TA] .
These 10 animal facts will amaze you. The obturator foramen is a narrow hole surrounded in part by the pubic bone and the base of the hip bone. When part of the abdominal wall pushes through the obturator foramen, it is called an obturator hernia. This type of hernia is extremely rare, very difficult to diagnose, and is most common in women older than 70 who have recently lost a significant amount of weight.
