Colposcopic examination was done in 189 successive . parturients within 6 to 48 hours of delivery for evidence of type, site and extent of cervical trauma and its relation to various obstetric factors. There was trauma in 66% of cases, as erosion in 79%, as laceration in 56%, as brusing in 30% and as yellow areas in 17%. In about two thirds of cases, the diameter of cervical erosion, or the length of laceration did not exceed 5 .m.m and 81% of lacerations were of first degree. Cervical injury was significantly more frequent in preimiparae, in the anterior cervical lip, in occipito-posterior po?itions and with premature rupture of membranes. In 117 parturients with cervical injury another colposcopic examinaiton was done 6 to 8 weeks postpartum. In 8% there was residual cervical damage
