Detachment of posterior uterine cervical lip associated with spontaneous delivery.

Various forms of detachment and amputation of the uterine cervix during labor have been described as an unusual and uncommon obstetrical complication (Jeffcoate and Lister, 1952). These cases most probably are not so rare as the few papers dealing with them would suggest. Since most of these papers deal with total amputation (annular detachment) of the uterine cervix and detachment of anterior uterine cervical lip, a case of spontaneous detachment of posterior uterine cervical lip is described.
