correctly label the following anatomical parts of a flat bone

Some bones in the fingers are classified as long bones, even though they are short in length. Long bones contain yellow bone marrow and red bone marrow, which produce blood cells. The epiphyseal line is a remnant of an area that contained hyaline cartilage that grew during childhood to lengthen the bone. The ends of a long bone contain spongy bone and an epiphyseal line. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. Clinical Relevance: Pelvic FracturesA long bone is a bone that has greater length than width.

Circumferential pressure is applied by the binder at the level of the greater trochanters – an important anatomical landmark. As a result, major trauma patients are assumed to have a pelvic fracture until proven otherwise and a ‘ pelvic binder’ is used to stabilise the pelvis and minimise further bleeding. In the context of a high energy major trauma patient, the pelvis can be a major source of bleeding due to fracture. Vascular injury can result in life threatening haemorrhage. In particular, the bladder and urethra are at high risk of damage.

Higher energy injuries can be associated with soft tissue and vascular injury.

These can be ‘unstable’ injuries and may require urgent surgery.

These result in more extensive fractures which may include the acetabulum and sacroiliac joint.

For example, after a high speed road traffic accident.

High energy injuries with direct or transmitted trauma:.

These are usually ‘stable’ injuries, not requiring surgery.For example, a simple fall from standing height in an osteoporotic patient resulting in pubic rami fracture.There are two broad groups of pelvic fractures:
