Learning Objectives1) Identify the specified bony landmarks of the bones of the

pelvic girdle on disarticulated bones2) Identify the joints of the pelvic girdle on a skeletal model3) Locate the origins and insertions of the pelvic girdle

muscles on a skeletal model4) Demonstrate the anatomical course of the pelvic girdle

muscles on a skeletal model5) Identify bony and soft tissue structures that are palpable in

the pelvic girdle region6) Palpate specified pelvic girdle structures by correlating

anatomical structures with surface anatomy landmarks7) Perform, describe and name various special tests that

screen for common pathological conditions of the pelvic girdle


Bony Landmarks Identify these landmarks on the disarticulated bones

Sacrum Sacral Base Sacral Promontory Superior Articular

Process Ala Sacral Hiatus Foramina Auricular Surface

Ilium Iliac Crest Iliac Fossa Anterior Superior Iliac Spine Anterior Inferior Iliac Spine Posterior Superior Iliac

Spine Posterior Inferior Iliac Spine Auricular Surface Tuberosity


Bony Landmarks Cont. Identify these landmarks on the disarticulated bones

Ischium Ischial Tuberosity Body Ramus Spine

Combine Ilium, Ischium, Pubis Acetabulum Obturator Foramen Greater Sciatic Notch

Pubis Body Inferior Ramus Superior Ramus Pubic Tubercle


Lumbosacral Joint

Sacroiliac Joint

Pubic Symphysis

Joints & ArticulationsIdentify these joints & articulations on the skeleton


Bony PalpationAnterior Superior Iliac Spine Stand in front of your patient and

palpate both ASIS’s simultaneously with your thumbs. If they are not on the same plane, the patient may have a pelvic obliquity.

Hoppenfeld Figure 6-1


Bony PalpationIliac Crest Stand in front of your patient and

palpate both iliac crests simultaneously. With your palm facing the floor, place both hands on top of the iliac crests and press down gently. Males tend to have higher iliac crests, or a “taller” pelvis than women. If both iliac crests are not on the same plane, the patient may have a pelvic obliquity.



Bony PalpationPubic Tubercles The pubic tubercles are best palpated

with your patient lying supine. Start with your thumbs a bit higher than the level of the tubercles and palpate down to the most superior edge of them. Take caution to protect modesty and ask specific permission from your patient prior to palpating in this region. If they are not on the same plane, the patient may have a pelvic obliquity.



Bony PalpationPosterior Superior Iliac Spines

Standing behind your patient, palpate both PSIS’s simultaneously using your thumbs. The PSIS’s lie at the most posterior end of the iliac crest and are noted to be just deep to the visible “dimples” on the buttock. If they are not on the same plane, the patient may have a pelvic obliquity.



Bony PalpationIschial Tuberosity The ischial tuberosity is located at the

level of the gluteal fold. It is most easily palpated with the patient in the sidelying position with the hip in flexion, however to compare the symmetry between both ischial tuberosities, the prone position should be used. If they are not on the same plane, the patient may have a pelvic obliquity.



Bony PalpationSacroiliac Joint/ Sacral Base While the sacroiliac joint and sacral base

themselves are not palpable due to obstruction from the ilium and supporting ligaments, the position of the sacral base can be assessed indirectly by the following method. Place your patient in the prone position and palpate both PSIS’s with your thumbs. Move both thumbs medially until they drop onto the sacrum at about the S2 level. Observe the position of your thumbs for symmetry with respect to depth.



Special TestsLeg Length Discrepancy True Leg Length Measurement:

Measure from the concavity just below the ASIS to the most distal margin of the medial malleolus.

Apparent Leg Length Measurement:

Measure from the umbilicus to the medial malleolus of the ankle.

Special TestsGillet testThis test is used to identify if one or both SI joints are hypomobile or fixated. The subject stands while the examiner palpates the PSISs. The subject is asked to flex the hip and bring the knee toward the chest. The examiner should feel the PSIS move inferiorly during this maneuver. If the PSIS does not move inferiorly, this is a positive test, indicating SI hypomobility or fixation on that side.

Special TestsLong-Sit Test

This test is used to screen for an anteriorly or posteriorly rotated innominate bone. The subject assumes a hooklying position, then performs a bridge (lifting the buttocks off the table) in order to assure normal alignment. The subject then moves into a supine position with the LEs fully extended. The examiner stands with their thumbs on the patient’s medial malleoli and assesses relative position. The subject then moves into long sitting, and the examiner reassesses the position of the malleoli. Interpretation of lower extremity change in length from supine to long sitting is as follows:

Short to Long = Posterior Innominate RotationLong to Short = Anterior Innominate Rotation
