KEY ANATOMIC FEATURES OF THE TRUE PELVIS• Sacral promontory
• Retropubic angle
• Width of the sacrosciatic notch
• Anterior surface of the sacrum
• Ischial spines and tuberosities
• Inner surface of the ischium
• Suprapubic arch
• Descending pubic rami
• Coccyx
![Page 6: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/6.jpg)
THE INLET• Diagonal Conjugate – distance from the sacral promontory to the to the inferior margin of
the symphysis pubis
• OC = DC-1.5cm
• Contracted: OC <10.5cm
![Page 7: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/7.jpg)
THE INLET: THE RETROPUBIC ANGLE
• A.K..A. the forepelvis in older textbooks
• Performed by placing 2 fingers under the pubic arch, dropping wrist, and palpating the symphysis and both superior pubic rami
• ANDROID PELVIS: sharp and acute
• PLATYPELOID PELVIS: flat nearly 180degrees like a blackboard
• GYNECOID PELVIS: flat in the midline, curves gently backward laterally
• ANTHROPOID PELVIS: backward curve is detected earlier and curves back more sharply
![Page 8: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/8.jpg)
THE MIDPLANE• Lower sacral vertebrae
• Sacrum: Flat or hollow (flat is less common)
![Page 9: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/9.jpg)
THE MIDPLANE
• Sacrospinous ligament
• Less than 2 fingerbreadths implies a narrow sacrosciatic notch
• A 3 fingerbreadth ligament directed more laterally than anteriorly suggests a platypeloid pelvis
• Anthropoid pelvis also is 3 fingerbreadths or more directed more anteriorly than laterally
![Page 10: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/10.jpg)
THE MIDPLANE• Ischial spines: prominent, blunt or average
![Page 11: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/11.jpg)
THE MIDPLANE: BISPINOUS DIAMETER
• Not readily assessed clinically
• Separate examining fingers as wide as possible
• In the rare contracted pelvis one may be able to span the distance between spines
![Page 12: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/12.jpg)
THE MIDPLANE• Ischial spines: prominent, blunt or average
• Slope of the pelvic sidewall
• Straight
• Convergent: Funnel shaped or android pelvis
• Divergent: “Blunderbuss” pelvis
![Page 13: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/13.jpg)
THE MIDPLANE: “BLUNDERBUSS”
![Page 14: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/14.jpg)
THE OUTLET• Coccyx: The shape and mobility should be described
• Suprapubic angle
• Gynecoid pelvis: suprapubic angle > 90 degrees. Suprpubic arch is characterized as “Norman”
• Android pelvis: exam fingers will be forced to overlap at the top of the “Gothic” arch
• Bituberous diameter (BTD)
• Can be measured with a fist externally
• An narrow BTD (<8cm) increases the risk of deep perineal lacerations or extension of an episiotomy (odds ratio of 15)
• Narrow BTD is strongly indicative of an android pelvis
• Can also be found in an anthropoid pelvis

EDWARD DENNON’S FUNDAMENTAL RULES• FAVD must be considered a surgical procedure
• It should be done by a trained, coordinated operating team including an operator, assistant, anesthesiologist, scrub and circulation nurse
• Fully equipped room to handle any emergency
![Page 18: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/18.jpg)
THE INTERN
• “The intern, before being allowed to perform a forceps delivery operation, should be given a series of painstaking lectures on the subject. He should be drilled in detail, repeatedly, on the manikin and he should assist at numerous operations which, in turn, should be reviewed on the manikin.”

ACOG PRACTICE BULLETIN #17, JUNE 2000, REAFFIRMED 2009
• Level A• Forceps and Vacuum are acceptable and safe instruments for operative vaginal delivery.
Operator experience should determine which instrument to use
• Vacuum is associated with increased incidence of neonatal cephalohematomas, retinal hemorrhages, and jaundice when compared with forceps delivery
• Level B• Minimize duration of vacuum application
• Midforceps operations should be considered an appropriate procedure to teach and to use under correct circumstances by an adequately trained individual
• Incidence of intracranial hemorrhage is highest with cesarean following failed vacuum or forceps. The combination of vacuum and forceps has a similar incidence. Operative vaginal delivery should not be attempted when the probability of success is low
![Page 52: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/52.jpg)
ACOG PRACTICE BULLETIN #17, JUNE 2000, REAFFIRMED 2009
• Level C• Operative vaginal delivery is not contraindicated in cases of suspected macrosomia or
prolonged labor; however caution should be used because the risk of shoulder dystocia increases with these conditions
• Neonatal care providers should be made aware of the mode of delivery in order to observe for potential complications associated with operative vaginal delivery
![Page 53: Clinical pelvimetry and Forceps Assisted Vaginal Delivery](https://reader036.vdocument.in/reader036/viewer/2022062401/58f2807b1a28ab63738b45ab/html5/thumbnails/53.jpg)

TEACHING LAUFE-PIPER FORCEPS TECHNIQUE AT CESAREAN DELIVERY• University of Texas Galveston, Locksmith, Yeomans, Hankins et al
• Objective: To present a method of teaching forceps during cesarean breech deliveries using Laufe-Piper forceps and to evaluate its usefulness
• For several years residents were taught this method of delivery. To assess residents experience, recent graduates and 3 rd and 4th year residents completed a survey as well as matched controls from other programs were this was not taught.
• Responses from 32 (74%) study subjects and 63 (71%) controls.
• Study subjects rated themselves more comfortable using piper forceps and noted greater annual use of forceps for vertex deliveries.
• CONCLUSION: Laufe-Pipers can be used for cesarean delivery of breech-presenting infants. This practice promotes confidence and skill for their use at vaginal delivery.

TEACHING LAUFE-PIPER FORCEPS TECHNIQUE AT CESAREAN DELIVERY• No maternal or neonatal complications have been attributed to this practice
• Because the Laufe-pipers lack handles they are shorter than conventional pipers; this offers a distinct advantage at cesarean
• The similarities of application of forceps at cesarean provide practice for vaginal breech application of pipers to the aftercoming head
• After application, head flexion is ensured by elevating the shanks slightly and lowering the infants body against them.
• Extraction is accomplished by pulling outward and raising the grips

TEACHING LAUFE-PIPER FORCEPS TECHNIQUE AT CESAREAN DELIVERY• Vaginal breech delivery is rarely performed
• In an emergency situation it may be the best option
• It may be used for breech extraction of twin B
• Because the rarity of breech deliveries in residency, educational opportunities are sparse
• Laufe-Pipers for breech cesarean has been found to be of educational benefit

BABY SIMPSONS AT CESAREAN• We have forceps in every cesarean tray
• Please see Williams Obstertrics, chapter on Forceps through the Coy Carpenter Library and watch the animated video forceps during cesarean.
• Excellent option for the floating head
• Excellent option for the difficult delivery

RESIDENT GENDER• >350,000 deliveries
• By >800 OBGYN residents in the US from 1994-1998
• Percentage of total deliveries performed with forceps during residency was higher among male residents
• Percentage of vaginal deliveries with forceps was also higher
• Percentage of overall operative vaginal deliveries was significantly higher for males
• Percentage of vacuum deliveries did not vary by gender
