Activity 5

1 The Android pelvis is so called because it resembles the male pelvis. Note the funnel shape of the pelvis. With the knowledge you have obtained, what position and presentation may the fetus adopt? What problems may be experienced in labour for the woman and fetus? What type of delivery may be the outcome?

2 The anthropoid pelvis, you will have discovered, shows very definite features. The fetus commonly presents as a direct occipito-anterior or occipito-posterior position. What would be the probable course of labour and outcome in either of these two cases?

3 The distinct shape of the platypelloid pelvis with the kidney shaped brim in which the anteroposterior diameter is reduced and the transverse increased, means the head must engage with the sagittal suture in the transverse diameter. Can you envisage any problems for a mother undergoing labour with this type of pelvis.
