Question 27

Pelvic girdle

Answer 27

* Consists of the sacrum and two hip (coxal) bones * comprised of three joints * sacroiliac x2 * pubic symphysis

Question 28

Sacroiliac joint

Answer 28

* Articulation between the sacrum and two ilium bones * synovial gliding jt that allows slight movement

Question 29

hip joint

Answer 29

* Common orthopedic surgery is a total hip replacement (THA or THR) * broken hip usually refers to a fractured neck of femur * congenital dislocation of the hip is common and treatable with orthotics and strengthening exercises

Question 30

Tibiofemoral joint

Answer 30

* The largest synovial joint in the body * the most complex and frequently injured joint of the body * modified hinge joint * permits flexion and extension * with knee in flexed position, it also allows for some internal and external rotation

Question 31

Joint terminology (cruciate and collateral ligs)

Answer 31

* cruciate * will be paired * means cross * collateral * will be paired * run parallel to each other on opposite sides of the joint (typically medially and laterally)

Question 32

ACL

Answer 32

anterior cruciate ligament * originates on the posterior aspect of the lateral condole of the femur and attaches on the anterior aspect of the tibia at the intercondylar area * prevents anterior movement of the tibia under the femur * named anterior because of te attachment site on the tibia * injuries * sudden deceleration * hyperextension * pivoting in place

Question 33

PCL

Answer 33

Posterior cruciate ligament * attaches to the posterior intercondular area and passes anterosuperiorly to insert into the lateral surface of the medial femoral condyle * when the knee is in extension, it makes an almost 90 degree turn as it passes anterosuperiorly * the ACL passes lateral to it and curves around it * prevents posterior translation of the tibia under the femur * stronger than ACL * named posterior because of the attachment site on the tibia * injuries * direct blow to the anterior aspect of the knee while the knee is in slight flexion * MVA * direct fall onto the knee * 20% of knee ligament injuries involve the PCL

Question 34

MCL and LCL

Answer 34

medial and lateral collateral ligaments * MCL * distal medial femur to medial tibia * firmly attached to the medial meniscus * LCL * distal lateral femur to head of fibula * add to the stability of the knee joint * resist forces acting on the sides of the knee joint * injuries * direct blow to the side of the knee

Question 35

Tibiofibular joint

Answer 35

* proximal * articulation between the lateral condyle of the tibia and head of the fibula * distal * articulation between the distal ends of the tibia and fibula

Question 36

Ankle joint

Answer 36

* excessive inversion can result in a sprained ankle (involves anterior talofibular ligament) * other ankle ligaments may be involved in sprain injuries * eversion ankle injuries generally involve bone fractures rather than ligament tears * medial deltoid ankle ligament so strong it will break bone rather than tear

Question 37

Transverse tarsal joint

Answer 37

* comprised of two joints * talonavicular joint * calcaneocuboid joint * together these two joints constitute the transverse tarsal or mid-tarsal joint
