The uterus does not increase specially in its posterior part, but quite uniformly, so that, as might be expected, the fundus gradually detaches itself from the abdominal wall.

Even if the adhesions were not broken down they would of necessity be so stretched as to be useless for their original purpose after delivery.

Bands of adhesion could not share in the process of involution.

As, however, the uterus undergoes perfect involution, it is restored to its original condition before the onset of the disease which rendered hysteropexy necessary." The coexistence of an extensive tumor of the uterus with pregnancy does not necessarily mean that the product of conception will be blighted.
Brochin speaks of a case in which pregnancy was complicated with fibroma of the uterus, the accouchement being natural at term.

Byrne mentions a case of pregnancy complicated with a large uterine fibroid.
Delivery was effected at full term, and although there was considerable hemorrhage the mother recovered.
