What is CT Pelvimetry?

A CT pelvimetry is a study which assesses the size of the bony pelvis to determine whether a normal vaginal delivery is a viable option.

What is pelvic axis Slideshare?

Pelvic AxesObstetric axis* It is an imaginary line represents the way passed by the head during labour.* It is J shaped passes downwards and backwards along the axis of the inlet till the ischial spines where it passes downwards and forwards along the axis of the pelvic outlet.www.freelivedoctor …

What does inadequate pelvis mean?

Pelvimetry is the measurement of the female pelvis. It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal.

How is contracted pelvis diagnosed?

Try to palpate the sacral promontory to measure the diagonal conjugate. Normally, it is 12.5 cm and cannot be reached. If it is felt the pelvis is considered contracted and the true conjugate can be calculated by subtracting 1.5 cm from the diagonal conjugate . This assessment is not done if the head is engaged.

How is Pelvimetry done?

Background. Pelvimetry assesses the size of a woman’s pelvis aiming to predict whether she will be able to give birth vaginally or not. This can be done by clinical examination, or by conventional X‐rays, computerised tomography (CT) scanning, or magnetic resonance imaging (MRI).

What are the 4 types of the pelvis and their descriptions?

While pelvis shape can vary widely among females, there are four general types: gynecoid, android, anthropoid, and platypelloid. The shape of your pelvis may affect whether you can give birth vaginally. The gynecoid pelvis is the most common pelvis shape in females and is favorable for a vaginal birth.

How is clinical Pelvimetry done?

When does a pelvimetry show severe disproportion?

• It is based on clinical findings and pelvimetry:- a) Severe disproportion:- when the obstetric conjugate is less than 7.5 cm (3”) then it is said to be severe disproportion. a) Borderline disproportion:- when the obstetric conjugate is between 9.5 and 10 cm.

How to explain the diagnosis of CPD and contracted pelvis?

• To explain the diagnosis of CPD and contracted pelvis • To enumerate the effects of contracted pelvis. • To describe the management of the CPD and contracted pelvis. • To enlist the complication of the CPD. 5. • Cephalo pelvic disproportion is the disparity in relation between the head of baby and the mother’s pelvis.

What is the transverse diameter of the pelvic bone?

•Transverse diameters: o Bituberous diameter = 11 cm  between the inner aspects of the ischial tuberosities. o Bispinous diameter = 10.5 cm  between the tips of ischial spines. Diameters of pelvic outlet 26. Pelvic anatomy • Bony pelvis • Pelvic diameters • Pelvic planes • Pelvic axes • Pelvic types • Pelvimetry

What are the measurements of the maternal pelvis?

50.  represent the amount of space available at each level.  The key measurements for assessing the capacity of the maternal pelvis include the following: 1. The obstetric conjugate of the inlet 2. The bispinous diameter 3. The bituberous diameter 4. The posterior sagittal diameter at all levels 5. The curve and length of the sacrum 6.
