Purpose: Pyrocarbon disc interposition arthroplasty has been designed for the surgical treatment of Eaton-Glickel grade II/III carpometacarpal thumb joint arthritis. This study presents the results of this technique with a minimum 5-year follow up.
Methods: We assessed 4 questionnaires for patient-reported outcome measurements in a cross-sectional study: the Patient-Rated Wrist and Hand Evaluation, Disabilities of Arm, Shoulder, and Hand questionnaire, Michigan Hand Questionnaire, and questions about satisfaction at the 5-year follow up. We evaluated grip and pinch strength, range of motion, and the radiological position of the disc. Finally, a Kaplan-Meier survival analysis was performed.
Results: A total of 164 thumbs (in 137 patients) were available for follow-up varying from 5 to 12 years. Median Patient-Rated Wrist and Hand Evaluation, Disabilities of Arm, Shoulder, and Hand, and Michigan Hand Questionnaire scores were 17, 18, and 76, respectively. The satisfaction score was 9 (Likert scale of 1-10). Grip and pinch strength reached nearly 100% compared with the contralateral hand. Range of motion resulted in a Kapandji score of 10. Thumb height showed a marginal loss and the Kaplan-Meier survival curve showed a survival rate of 91%.
Conclusions: Our study suggests that pyrocarbon disc interposition arthroplasty is a reliable and feasible treatment for carpometacarpal thumb joint arthritis at medium-term follow-up. It was associated with a high level of patient satisfaction; it maintained thumb height and the implant survived in 91% of patients. Strength and range of motion were comparable to the contralateral hand after a minimum follow-up of 5 years.
Type Of Study/level Of Evidence: Therapeutic IV.

Background: To compare pyrocarbon disc interposition arthroplasty (PDI) with trapeziectomy plus ligament reconstruction tendon interposition (LRTI), the authors assessed whether PDI resulted in a higher pinch strength, and compared grip strength, range of motion (ROM), patient-reported outcomes, satisfaction, and complications between the approaches.
Methods: Because of scarcity of preoperative hand measurements, the authors performed a descriptional cross-sectional cohort study of patients operated on between 2006 and 2014, with a minimum of 5 years of follow-up. Patients were treated with PDI or LRTI.

Unlabelled: In cases of isolated carpometacarpal (CMC) thumb joint osteoarthritis, a hemitrapeziectomy can be performed. To address the risk of subsidence of the first metacarpal, a pyrocarbon disc has been designed as an interposition prosthesis. The disc is made of pyrolytic carbon with the same elastic modulus as cortical bone, making it resistant to wear from surrounding bone.

The aim of this study was to minimize the risk of life-threatening thromboembolism in the ventricle through the use of a new biomimetic heart valve based on metal-polymer composites. Finite volume element simulations of blood adhesion to the material were carried out, encompassing radial flow and the cone and plane test together with determination of the effect of boundary conditions. Both tilt-disc and bicuspid valves do not have optimized blood flow due to their design based on rigid valve materials (leaflet made of pyrolytic carbon).

Pyrocarbon disc interposition arthroplasty is an effective treatment for thumb base osteoarthritis. However, as with all implant techniques, the disc can (sub)luxate over time. The relationship between disc position, the experienced pain, and the necessity for revision surgery is not known.

Structural failure of mechanical heart valve was a known feature when it was evolving in the 1960s and 1970s. With the advent of pyrolytic carbon and a better design, it is a rare entity with present valves. We report a case of disc fracture leading to acute mitral regurgitation in TTK Chitra heart valve prosthesis (CHVP) (TTK Healthcare Limited, India) heart valve, 6 years after its implantation in mitral position.
