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.
