“…(2017) hypothesized that loosening may be due to implants that do not sufficiently respect the kinematics of the TMC joint. Bozentka (2010) considered that the loads transmitted during the thumb-index pinch grip are magnified 10 to 13 times at the TMC joint, which places high stresses on the trapezial component and increases the risk of migration. Duerinckx and Caekebeke (2016) also highlighted the importance of correct cup orientation.…”

In this retrospective study we reviewed the outcomes of 46 trapeziometacarpal joint replacements with the Moovis® prosthesis in 46 patients with painful osteoarthritis. The dual mobility design of this prosthesis aims to reduce prosthetic dislocation and subsidence. At follow-up 2 to 6 years (mean 5 years) after operation, pain was reduced from 6 to 0 on a visual analogue scale from 0 to 10. The scores of the Quick Disabilities of the Arm, Shoulder and Hand questionnaire improved significantly. Thumb motion and grip and pinch strength did not differ significantly from the contralateral hand. There were no radiographical signs of implant subsidence or loosening. No implant required revision. Forty-five patients rated the result as excellent or good. We conclude the Moovis® is a reliable and effective implant at short- to mid-term follow-up. Level of evidence: IV

“…Pinch forces at the pulp of the thumb are magnified 10 to 13 times at the trapeziometacarpal level, leading to significant stress on the implant and increasing the risk of loosening. In the normal TMC joint of the thumb, there is no fixed, single centre of rotation and, as a consequence, the motion in a spherical prosthesis construction may be deleterious for cup fixation or cause exaggerated wear and tear, and perhaps even dislocation (Bozentka, 2010).…”

We present a prospective follow-up of 39 Elektra prostheses in 37 patients (32 women and five men), with a mean age of 56.5 (range 46-71) years; 34 patients had osteoarthritis and three had rheumatoid arthritis. Patients were followed using clinical examination, including measurement of pain on a visual analogue scale, mobility, and strength, after 6, 12, 26, and 52 weeks, and annually thereafter. Radiological examination was done preoperatively and after 6, 26, and 52 weeks, and annually thereafter. The mean follow-up time was 48 (range 3-91) months. Although we observed a fast recovery, including maintenance of mobility and a gradual increase in grip strength, there was a revision rate of 7/38 (24%) after 36 months, increasing to 17/38 (44%) after 72 months. The main reason for revision was loosening of the trapezial component, and biomechanical properties of the trapezial fixation may be the key problem in treating trapeziometacarpal osteoarthritis using a total prosthesis.

“…A complete review of the many implants that have been developed for the CMC1 joint is beyond the scope of the present thesis, but a summary will be offered before we discuss the Elektra implant more closely. For more detail, the reader is referred to review articles by Linschield (Linscheid, 2000) and Bozentka (Bozentka, 2010). In addition, a review article that summarises published results for CMC1 joint replacements was published in 2014 (Huang et al, 2015).…”
