Complications associated with autogenous bone marrow aspirate harvest from the lower extremity: an observational cohort study.
The purpose of this article is to report the complications associated with autogenous bone marrow aspirate harvested from the lower extremity (ie, tibia and/or calcaneus) for soft tissue and/or osseous healing augmentation. This is a multisite, multisurgeon, observational cohort study involving retrospective review of prospectively collected data of 548 autogenous bone marrow aspirate harvests from the lower extremity of 530 consecutive patients between August 2000 and March 2009. Each patient underwent autogenous bone marrow aspirate harvest from the proximal medial tibial metaphysis, distal medial tibial metaphysis, medial malleolus, lateral calcaneus, medial calcaneus, or a combination of both the proximal tibial metaphysis and lateral calcaneus for application to split-thickness skin graft application sites or for mixture with allogeneic bone graft material for osseous defects or arthrodesis. Patients were kept non-weight bearing based on the index procedure and followed until clinical healing occurred or failure was declared. There were 324 female and 206 male patients with a mean age of 54.7 +/- 14.1 years (range: 14 to 84 years). There were 276 left feet/ankles and 272 right feet/ankles undergoing operative interventions with 18 harvests occurring from the proximal medial tibial metaphysis, 183 from the distal medial tibial metaphysis, 11 from the medial malleolus, 325 from the lateral calcaneus, 3 from the medial calcaneus, and 8 from both the proximal tibial metaphysis and lateral calcaneus. All procedures were deemed successful with no nerve-related injury, infection, wound-healing complications, or iatrogenic fracture occurring. When properly performed, autogenous bone marrow aspirate harvest from various locations about the lower extremity as described here represent safe and minimally invasive techniques useful for soft tissue and osseous healing augmentation.
