“…Despite this, the lack of osteointegration between the pyrocarbon and host bone could be demonstrated (Daecke 2006), and was considered the reason for the high rate of periprosthetic radiolucencies observed. Clinical outcomes, however, did not correlate with the radiological findings in these early reports.…”

There have been limited publications that report long-term outcomes of pyrocarbon implants. This report describes both clinical and radiographic long-term results for patients who have been treated with pyrocarbon proximal interphalangeal implants. Thirteen implants in ten patients are reported for an average follow-up of 8.3 years (range 6.2-9.3). All patients were suffering from degenerative joint disease. Five of the 13 digits were free of pain, the remaining eight digits had mild to moderate pain (visual analogue scale 2-5). The average active range of motion was 58° (SD 19°) at latest examination. X-ray results were unremarkable in six digits with an acceptable position of the prosthesis. However, in seven patients significant radiolucent lines (≥ 1 mm) were observed. Three prostheses demonstrated a migration of the proximal component, and one a subsidence of the distal component. Our study does not support the use of this implant for treatment of osteoarthritis of the finger joint owing to high complication rates and limited range of motion.

“…However significant radiolucent lines surrounding the prosthesis (≥ 1 mm) were observed. This was understood to be somewhat expected, owing to the carbon surface of the implant not osteointegrating to the bone (Daecke et al, 2006).…”

“…It has a cobalt-chrome (CoCR) alloy metacarpal hemispherical head that articulates against an Ultra-High Molecular Weight (UHMW) PE phalangeal component ( Figure 3A). The phalangeal component is to be inserted generally with cementation, whereas the metacarpal component with its titanium coated stem was primarily manufactured for uncemented insertion based on the osseointegration concept for endoprosthetic reconstruction of small joints in the hand [37,38]. However, if the metacarpal intramedullary space is widened due to bone resorption with cortical thinning such as in our case, cementation of the titanium coated stems, that is useful in PIPJ arthroplasty as well [39], is inevitable.…”

A 72-year-old male with high-demand activities of daily living presented with rheumatoid arthritis mostly affected finger joints of his right hand. Radiographically, there was severe destruction with luxation of metacarpophalangeal joints (MCPJs) II-V. The constrained RM prostheses were inserted into the MCPJs II-V typically in the uncemented manner, and the course was primarily complicated due to periprosthetic fracture of the metacarpal IV intraoperatively, that was treated with immobilization in a plaster splint for 6 weeks. After that, the course was uncomplicated. Eight years after primary surgery, the patient reported increasing pain with loss of function isolated in his MCPJ IV since 6 months; all other finger joints did not reveal any clinically relevant symptoms. Radiographically, distinctive osteolyses with cortical thinning around all components of the 4 RM prostheses were seen, and the hinge joint of implant in MCPJ IV was broken. A total exchange arthroplasty of the MCPJ IV using the unconstrained MCPJ resurfacing SR TM MCP implant with cementation of both components was performed. At the 10-year follow-up, that includes a 2-year followup after MCPJ IV exchange arthroplasty, there was unchanged correct positioning of all MCPJ implants; and despite distinctive radiographic loosening and subsidence of the 3 other RM prostheses, the patient is able to perform his high-demand activities of daily living.
