Background: Adverse reactions to metal debris are significant complications after metal-on-metal total hip arthroplasty. Recently, late appearances of adverse reactions to metal debris and subsequent need for reoperations have been reported with small-diameter head metal-on-metal devices. We retrospectively investigated mid-term clinical outcomes of small-head metal-on-metal total hip arthroplasty. Methods: We reviewed 159 hips in 139 patients who had a small-head metal-on-metal total hip arthroplasty (M2a Taper; Biomet, Warsaw, IN) with a minimum 5-year follow-up and documented postoperative complications. Results: Focal osteolysis in either the femur or acetabulum was observed in 12 hips (7.5%, 44 months after surgery on average), with pseudotumor observed in 8 hips (5%, 120 months after surgery on average). Four hips (2.5%) had dislocations (84 months after surgery on average) and six hips (3.8%, 122 months after surgery on average) underwent reoperation. Conclusion: Small-head metal-on-metal total hip arthroplasty is associated with a high degree of complications at mid-term follow-up period. Considering this, we discourage the use of metal-on-metal total hip arthroplasty regardless of head size.

Metal-on-metal (MoM) hip arthroplasty was re-popularized in the 1990s to resolve osteolysis and wear associated with metal-on-polyethylene products. Despite early success, registries began reporting high failure rates due to adverse reactions to metal debris (ARMD), manifesting as pseudotumors, hip effusions and osteolysis. Evaluation includes clinical exam, advanced imaging, and blood metal ions and infectious markers. This review provides physicians with an evidence-based update on the 1) clinical workup and management of patients with existing MoM implants, 2) risk and prognostic factors associated with suboptimal results and 3) the precipitating events and lessons learned applicable to future orthopedic prosthesis.
