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.
