Q

Considering what you know about how the hip bones form, why can hip dysplasia be successfully treated by splinting if applied early?

A

3 hip bones fuse together at the acetabulum during childhood.
Splinting holds the femoral head in place so the acetabulum and surrounding ligaments can form normally.

28
Q

What is true about the bones in the forearm?

A

The ulna is the medial bone.
The radius is the lateral bone.
The radius forms part of the wrist joint.

29
Q

What bony features are in or near the hip joint?

A

acetabulum, greater trochanter and neck of femur

30
Q

What bone is a sesamoid bone found in the lower limb?

A

patella

31
Q

Where are the greater and lesser tubercles located?

A

humerus

32
Q

Where is the lateral malleolus?

A

distal portion of the fibula

33
Q

What bone of the axial skeleton does the pectoral girdle attach?

A

sternum

34
Q

What bone features include the glenoid cavity and acromion?

A

scapula

35
Q

What bone features include the ala, crest, and greater sciatic notch?

A

ilium

36
Q

What membranous bone transmits forces from upper limb to thoracic cage?

A

clavicle fracture

A

radius

47
Q

What bone’s largest bone is the calcaneus?

A

tarsals

48
Q

What bone is involved in the formation of hip bones?

A
