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.
FAQs
Assessment focuses on bone remodeling, thickness, density, sclerosis, cysts, and lesions. Together, these findings describe whether the bone beneath cartilage retains normal structural integrity or shows changes relevant to joint disease. Considering several features rather than a single measurement helps characterize the cartilage–bone interface and supports a more complete interpretation of joint health.
Alterations in the bone beneath articular cartilage can provide information about how the cartilage–bone interface participates in joint pathology. Patterns such as remodeling, sclerosis, cyst formation, or lesions may help clarify relationships among structural change, pain, and disease progression. This perspective is important because joint assessment should consider both cartilage and its supporting subchondral bone.
Different analyses address different aspects of joint status. Imaging characterizes structural findings in the living joint, whereas histologic analysis can examine tissue features when appropriate, and biomechanical analysis can address functional properties. Combining these approaches allows structural integrity, tissue characteristics, and mechanical relevance to be considered together in clinical or research investigations.
The approach depends on the purpose of the assessment and whether tissue-level or mechanical information is needed in addition to structural imaging. Imaging supports evaluation of features such as thickness, density, sclerosis, cysts, and lesions. Histologic or biomechanical analysis may be added when appropriate to investigate tissue changes or functional consequences more closely.
It is useful when clinicians or investigators need to characterize joint changes associated with osteoarthritis, trauma, or other joint disorders. The findings can contribute to diagnosis and help monitor how structural abnormalities develop over time. Evaluation is also relevant when planning treatment, particularly when the condition involves the relationship between articular cartilage and the underlying bone.
Results can support diagnosis, disease monitoring, and treatment planning by documenting the condition of the bone beneath cartilage. In research, the same information helps investigate how subchondral changes relate to pain, joint deterioration, and preservation of joint function. These assessments also contribute to studies of therapies intended to protect or maintain the cartilage–bone environment.
