Acetabular Bone Marrow Aspiration During Total Hip Arthroplasty

Area of Science:

• Orthopaedic Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Biologically augmented surgical treatments are gaining traction in orthopaedics.
• Bone marrow aspirate concentrate (BMAC) is a vital orthobiologic source.
• Current trends favor local marrow aspirations over traditional iliac crest harvesting to minimize patient morbidity and procedural costs.

Purpose of the Study:

• To present a novel technique for bone marrow aspiration.
• To simplify the procurement of bone marrow aspirate concentrate (BMAC) during total hip arthroplasty (THA).
• To explore the feasibility of accessing the iliac marrow depot via an acetabular approach in THA patients.

Main Methods:

• A novel acetabular approach for bone marrow aspiration was developed and applied during total hip arthroplasty.
• The standard iliac marrow depot was accessed through this innovative surgical route.
• Bone marrow aspirate concentrate was collected using this minimally invasive technique within the THA procedure.

Main Results:

• The acetabular approach provides a simplified method for obtaining bone marrow aspirate concentrate.
• This technique integrates biologic augmentation seamlessly into the total hip arthroplasty procedure.
• The novel approach has the potential to reduce overall surgery time and associated costs.

Conclusions:

• A novel acetabular approach simplifies bone marrow aspiration for biologic augmentation in total hip arthroplasty.
• This technique offers a practical solution for utilizing bone marrow aspirate concentrate in a large patient cohort.
• Integrating BMAC aspiration into THA via this method enhances the efficiency of orthobiologic treatments.
