title: One-year results of use of poly-L/D-lactic acid joint scaffolds and bone packing in revision metacarpophalangeal arthroplasty.
abstract: Revision metacarpophalangeal arthroplasty after silicone implant arthroplasty is frequently complicated by severe bone loss, osteolysis and diaphyseal perforations. Impacted, morselised allografts are frequently used to treat bone loss in revision surgery. A new method of treatment using bioreconstructive poly-L/D-lactic acid (PLDLA) joint scaffold and allograft bone packing, after complete removal of the original silicone implants, allows recovery of bony deficiencies, correction of malalignment and improves function of the hand. This article presents the one-year results of a prospective, non-randomised clinical and radiographic follow-up study of 21 patients with 52 revision metacarpophalangeal arthroplasties using the PLDLA implants and allograft bone packing.
