“…Due to its remarkable properties; low friction coefficient, resistance to wear, biotolerance, a density and elasticity close to those of cortical bone, Pyrocarbon is now the ideal implant material for interposition. Pyrocarbon implants recently developed for the wrist and base of the thumb have proven the reliability of this material and validate the concept of free interposition as a method for arthroplasty [32][33][34][35][36].…”

“…Only one paper has been published describing the results in 12 patients of the use of a pyrocarbon implant as a spacer after resection of the distal scaphoid (Pequinot et al, 2005). The results of this pilot study lend further support to the suggestion that the STPI pyrocarbon prosthesis may have a place in treatment of this arthritis as a compromise between the other surgical techniques.…”

“…Making the spacer of a material other than silicone eliminates the risk of silicone synovitis. Pyrocarbon has excellent biocompatibility (Pequinot et al, 2005). The small operative procedure necessary to insert the spacer allows early mobilisation.…”

Isolated scaphotrapeziotrapezoid osteoarthritis is rare but can cause weakness and wrist pain. We present the results of a pilot study of interposition arthoplasty with a scaphoid trapezium pyrocarbon implant (STPI) by an open and arthroscopic approach for this problem. We performed this procedure in 10 hands in eight patients, all women, with a mean age of 60.5 (range 51-70) years. The average follow-up was 19 (range 2-24) months. Pre-operative X-rays in all cases identified an isolated degenerative arthritis of the scaphotrapeziotrapezoid joint. Average DASH evaluation pre-operatively of 49 was reduced to 39. All of the patients had functional improvement and returned to daily activities after 3 months. The results of this pilot study suggest that the STPI may prove a useful compromise treatment for this problem.

“…Interposition arthroplasty has proven to be less technically demanding, to require shorter period of immobilization and to have fewer complications when compared to STT joint arthrodesis (13). Table 1 highlights the clinical studies evaluating excisional arthroplasty (6,11,13,(15)(16)(17)(18).…”

Background: Introduction: Isolated scaphotrapeziotrapezoidal (STT) joint osteoarthritis (OA) is a relatively common condition. Scaphotrapeziotrapezoidal arthrodesis is the traditional treatment, while excisional arthroplasty with the use of flexor carpi radialis (FCR) or polycarbon implants represents a promising alternative surgical management. The present study aims to assess a novel alternative technique of excisional arthroplasty with the use of palmaris longus (PL) tendon as interposition material.Materials: The present research is a retrospective observational study. Patients suffering from symptomatic isolated STT OA, without midcarpal instability and treated with excisional arthroplasty with the use of PL tendon as interposition material, were evaluated. Five patients (two males and three females) with mean age of 63.8 years [standard deviation (SD)=16.9] were included. The mean follow up was 56.4 months (SD=9.8). In order to quantify the clinical results, we used the preoperative and postoperative visual analogue scale (VAS) score at rest and during activity, abbreviated Disabilities of the Arm, Shoulder and Hand (QuickDASH) score and postoperative ROM.Results: The postoperative VAS score at rest and during activity showed a decrease of 86.2% and 62.5%, respectively, when compared to the preoperative one. Regarding postoperative ROM at final follow-up, patients had a mean wrist flexion 71° compared to 78° of the contralateral hand, while the mean extension was found to be 57° compared to 66° of the contralateral side.Conclusions: The evaluated novel technique with the use of PL tendon as interposition material seems to offer satisfying results, while allowing to keep the FCR tendon intact. More studies comparing these techniques are of utmost importance to conclude which is the optimal treatment.
