Reconstruction of the first metacarpal after giant cell tumor excision using non-vascularised fibular autograft, ligament reconstruction and tendon interposition arthroplasty of the carpometacarpal joint

ABSTRACT

We report an innovative approach to reconstructing the defect after excision of giant tumor cell (GCT) involving the entire first metacarpal. Reconstruction was performed using non-vascularized fibular autograft fused at the metacarpo-phalangeal (MP) joint and soft tissue arthroplasty using ligament reconstruction and tendon interposition (LRTI) at the carpo-metacarpal (CMC) joint of the thumb. Two years after the procedure, the CMC joint had functional pain-free motion and radiographs showed fusion of the MP joint. The patient did not present with any major complication and was satisfied with the outcome of the procedure.
