Bone Marrow Aspiration: A Method to Obtain Bone Marrow to Examine Cell Morphology
0 Views •
2023
This video describes the technique of aspirating bone marrow from iliac spine and smear preparation for biopsy. In the example, we perform bone marrow aspiration from an acute myeloid leukemia (AML) patient and examine the cells to check for measurable residual disease (MRD), an important prognostic biomarker.

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...
FAQs
Bone modeling establishes form during growth by changing bone structure, whereas remodeling continuously renews existing tissue. Osteoblasts build bone and osteoclasts remove it, allowing internal architecture to respond to mechanical loading and metabolic demands. Distinguishing these processes helps explain how skeletal shape develops and how bone structure may change over time.
Cortical thickness describes the compact outer structure, while trabecular organization reflects the arrangement of the internal framework. Examining both provides a more complete assessment than considering overall size alone. Their patterns can reveal structural differences associated with mechanical adaptation, osteoporosis, fractures, or other conditions affecting skeletal architecture.
Mechanical loading contributes to the adaptation of internal bone architecture through ongoing remodeling. This relationship links form with function: regions exposed to different loading conditions may develop or maintain different structural patterns. Studying these patterns supports biomechanics research and helps clinicians interpret how altered loading may relate to alignment, degeneration, or injury.
Assessment can combine imaging, anatomical measurement, and three-dimensional reconstruction. Imaging reveals structural features, measurements quantify characteristics such as size or cortical thickness, and three-dimensional reconstruction supports evaluation of shape, alignment, and spatial architecture. Together, these approaches provide information for diagnosis, surgical planning, implant design, and skeletal research.
Clinicians can use morphological analysis when evaluating fractures, osteoporosis, congenital abnormalities, and degenerative conditions. The relevant assessment may include bone alignment, cortical thickness, trabecular organization, or anatomical variation. These findings provide structural context for identifying abnormal form and can support decisions in orthopedic care and related diagnostic investigations.
Detailed knowledge of bone shape, size, surface features, and three-dimensional architecture helps relate an implant or surgical approach to the patient’s skeletal structure. Morphological analysis can therefore support orthopedic planning and implant design rather than relying only on generalized anatomy. It also provides a basis for biomechanical studies and research into skeletal repair.
