Low-Cost Modification to Enhance Bone Marrow Aspiration Efficiency: A Technical Report

Bone marrow aspiration is an essential procedure for diagnosing hematological conditions and therapeutic applications, such as bone marrow aspirate concentrate (BMAC) therapy for non-union of bones. This report presents a case of a 35-year-old male with femoral non-union treated with BMAC, requiring the collection of a large bone marrow aspirate volume. A novel, low-cost modification to the standard bone marrow aspiration apparatus was developed using components from an intravenous (IV) drip set, including a rubber bulb connector and a luer lock connector. This modification enhanced suction efficiency and facilitated the safe collection of 90 ml of bone marrow aspirate in a single session. The procedure was completed without complications, and the cost of modification was minimal. This case demonstrates the potential of simple, low-cost innovations to improve procedural efficiency, particularly in resource-limited settings.
