Silicone Arthroplasty for Nonrheumatic Metacarpophalangeal Joint Arthritis

Long-term outcomes of silicone metacarpophalangeal arthroplasty: a longitudinal analysis of 325 cases

“…Though our sample size is small to comment on differential outcomes of MCP arthroplasty in the setting of post-traumatic or osteoarthritis, we did note a substantially increased risk of fracture and coronal plane deformity in these populations, as well as markedly higher implant failure in the post-traumatic arthritis group. This is in contradiction to previous studies that have demonstrated excellent outcomes with regards to pain relief and motion at intermediate and long-term follow-up in this non-inflammatory population (Morrell and Weiss, 2018; Namdari and Weiss, 2009; Neral et al., 2013; Rettig et al., 2005). Fracture rates for silicone implants in these populations have been quoted between 0%–11%, with an average follow-up between 47–56 months, where determination of fracture was based on review of radiographs without specific criteria for fracture identification (Namdari and Weiss, 2009; Neral et al., 2013).…”

The higher fracture rate noted in our series may be partially attributable to a broader definition of radiographic fracture that captures more subtle fractures.…”

Giant Cell Tumor of the Metacarpal: Case Report

“…When collateral ligament reconstruction is possible, either to an allograft or to native bone, unconstrained prosthesis including the pyrocarbon arthroplasty or surface replacement arthroplasty (SRA) is a viable option. 7,10,16,18,[20][21][22][23][24][25] This is an important consideration in younger patients given the high rate of fracture with silicone implants. 6,20 In our report, the patient initially had a satisfactory result after reconstruction with a fresh-frozen osteoarticular metacarpal head allograft.…”

“…Radiographs from the time of our initial evaluation showed a lytic expansile lesion involving the distal half of the metacarpal, extending to the articular surface (May16, 2006).…”

Metacarpophalangeal Arthroplasty for Osteoarthritis

“…When patients are not satisfied with nonoperative treatment, arthroplasty may be considered. 3 Silicone arthroplasties can be unstable and they can break leading to reactive synovitis in some cases. 4 Fixed fulcrum articulating implants have mixed results.…”
