OPEN SPECULUM EXTERNAL ROTATION. AS A PREDICTOR OF PELVIC FLOOR DISORDERS

In all gynecologists is treated by various known that the introduction of a speculum in the vagina and gently apart from warning should be performed in vertical sense after performing a rotation and placed transversely to the vertical axis of the vagina to proceed to opening and viewing of the cervix and vagina.

Well, for some time now I have watched that some patients, especially those who have had vaginal deliveries, which once opened from 30 to 45 degrees and placed in position, if left loose their experiences trigger external rotation similar to that occurring in the expulsion of the fetal head during labor, and the device normally placed upright again and more frequently trigger facing the thigh of the patient LH. I think it may be due to the accommodation of the leaflets toward the weaker side, less resistant, or more concave of the vaginal walls, driven by the stronger side of the vaginal muscles and pelvic floor.

This impulse is certainly motivated by voluntary or involuntary contraction of the levator ani and puborectalis portions in pubocoxígeo and transverse muscles of the perineum. It occurs to me that no primiparous pregnant, such proof could be introduced in late pregnancy (open speculum rotator Test) as predictor of correct external rotation of the fetal head during delivery. In nonpregnant patients, would be a mechanism for valuing a good or defective pelvic floor muscles, as if by contracting the pelvic muscles, the speculum is not broken, could deescartarse pelvic floor dysfunction.
