A novel approach to hallucal sesamoid pathology utilizing a 3D printed patient specific total sesamoid replacement implant: Case series

Abstract

Background: Sesamoidectomy can be associated with multiple complications secondary to loss of the intrinsic function of the excised sesamoid. We sought to mitigate these complications by preserving sesamoid function with a total sesamoid replacement (TSR) in lieu of sesamoidectomy. Method: Patient specific 3D printed TSR implants were designed and implanted for three patients who had exhaustively failed conservative measures. Follow up ranges from 7-36 months during which we evaluated for complications, symptom resolution, and patient satisfaction. Result: All patients had complete resolution of pain between 3.5-12 months postop and have remained satisfied with their outcome. No evidence of the aforementioned complications was observed. Conclusion: TSR may represent a viable alternative treatment option for most cases in which sesamoidectomy would otherwise be considered. Level of evidence: IV, case series.
