What does the term 'intramedullary' refer to in surgical procedures?

The term 'intramedullary' refers specifically to something that is located inside the bone marrow. In surgical procedures, intramedullary techniques often involve the insertion of rods or pins directly into the medullary cavity of a bone, which is where bone marrow is found. This approach is used frequently in orthopedic surgeries, particularly for stabilizing fractures.

Using intramedullary fixation methods can provide strong support while allowing for a more minimally invasive approach compared to traditional external fixations, as it relies on the structural integrity of the bone itself. The direct connection to the medullary cavity allows for better load distribution and encourages healing by maintaining the bone in a more functional alignment during recovery. This is particularly significant when considering the impact of the internal environment of the medullary cavity on the healing processes of the bone.
