100
The periphery surface of the acetabulum that is covered in hyaline cartilage. It articulates with the head of the femur and allows contact stresses to be uniformly distributed.
What is the lunate surface?
100
the primary stabilizers of the sacroiliac joint are:
What is anterior sacroiliac, iliolumbar, interosseous, and posterior sacroiliac ligaments?
100
This ligament consists of collagen fibers that run obliquely inferiorly and ventrally. They connect facing edges of spinous processes in lumbar vertebrae.
What is interspinous ligaments?
100
The standing position for the thoracic vertebrae is:
What is 40-45 degrees of natural kyphosis?
100
Deformity of hip where the angle formed between the head and neck of femur and its shaft is increased usually greater than 135 degrees.
What is coxa valga?
200
A ring of fibrocartilage that wraps the entire periphery of the acetabulum. It deepens the socket. It is triangular shaped and increases the concavity of acetabulum.
What is the acetabular labrum?
200
This thick, dense fibrous band attaches to the pubic crests and tubercles to suppor the superior aspect of the pubic symphsis.
What is the superior pubic ligament?
200
The lumbar superior articular facets are directed:
What is posteromedially/medially?
200
During ____ of the thoracic vertebrae, the superior vertebra laterally tilts, rotates, and translates over adjacent vertebra below. The intervertebral foramen is widened on the side contralateral to the ___ and narrowed on the ipsilateral side.
What is lateral flexion?
200
A/an __1___ approach requires the avoidance of flexion more than 80-90 degrees, adduction and internal rotation past neutral. A/an __2___ approach requires the avoidance of flexion greater than 90 degrees, hip extension, adduction, and external rotation past neutral.
1. What is a posterior approach? 2. What is an anterior approach?
300
These three bones form the pelvis.
What is the pubis, ischium, and the ilium.
300
The 3 distinct parts of the levator ani are:
What is pubococcygeus, iliococcygeus, and puborectus?
300
Iliocostalis, longissimus, spinalis. These muscles make up:
What is erector spinae?
300
Atypical thoracic vertebrae
What is T1, T10-12? T1: full costal facet superiorly that accepts entire head of first rb and a demifacet inferiorly that accepts part of the body of the second rib T10-12: single, full costal facet for articulation with head of 10-12 ribs --> LACK costotransverse joints
300
The relative anterior tilt of base of sacrum relative to ilium OR the posterior iliac on sacral rotation.
What is nutation?
400
This fan-shaped ligament resembles an inverted Y. It reinforces teh joint capsule anteriorly.
What is the iliofemoral ligament?
400
Pelvis on femoral hip ___ is restricted to 30 degrees because of natural limits of lateral bending.
What is adduction?
400
The mid-to-posterior part of the disc. It's purpose is to provide shock absorption capable of dissipating and transferring loads across consecutive vertebrae.
What is nucleus pulposus?
400
Extremes of thoracic extension are limited by:
What is tension in anterior longitudinal ligament and a possible impingement between laminae or adjacent downward sloping spinous processes?
400
With _____, one should use a cane on the contralateral side to activate ____.
What is weak abductors & lat dorsi?
500
The medial thigh muscles: adductor longus, adductor brevis, adductor magnus, gracilis, and obturator externus are innervated by:
What is the obturator nerve?
500
When the pelvis is shifted to the ___, the right hip joint will be adducted, and the left will be abducted.
What is the right?
500
Lumbar: The __ are short and thick forming the posterior and lateral walls of vertebral canal.
What is laminae and pedicles?
500
This motion occurs in the lumbar spine as the inferior articular facets slide inferiorly and slightly posteriorly relative to the superior facet.
What is extension?
500
What are the primary hip internal rotators?
What is TRICK QUESTION?! There are no primary internal rotators.
