Core Tip

Core tip: This unique presentation of hip swelling is only the seventh reported case of pseudotumor recurrence in a non-metal-on-metal total hip arthroplasty construct. These patients require a low threshold for clinical evaluation, using multiple modalities such as history, physical exam, magnetic resonance imaging, and serum metal ion level testing. The presentation, lab trends, and imaging findings of this case contribute to the growing base of knowledge surrounding the effects of corrosion in arthroplasty constructs with stem-neck modularity.
