Objectives/Interrogation: The purpose of this study was to report survival of the Aptis Distal Radioulnar Joint Implant Arthroplasty (Aptis).
Methods: We performed a retrospective review of patients who had at least 1 year follow up after Aptis arthroplasty from 2013 to 2017. Mean follow up was 3 years (1-5 years). Of 102 consecutive patients 1 was lost to follow up and was excluded. In our database we had one year follow up of functional outcome (DASH). Fifty six patients were treated with the Aptis as primary indication (instability and pain without prior surgery to the DRUJ) and 46 patients with the Aptis as rescue indication (pain after earlier ulnar resection, Sauve-Karpandi, other arthroplasties a.o.)
Results and Conclusions: DASH score improved from 58 (14) to 30 (15) after one year (n=102), (p<<0.01). Grip strength improved from 10 (8) kg to 25 (7) kg (p<<0.01).
Seventeen percent needed minor surgery (surgery to relieve pain due to synovitis of extensor tendons in 1st, 5th and 6th Compartment.
Five patients (5%) needed Removal of the Aptis, of these two Aptis were removed and treated with One-bone forearms and 3 had a revision arthroplasty due to infection with a functional Aptis at follow up.
All but two patients (98%) had a functional Aptis at follow up.
We have had good results with the Aptis Distal Radioulnar Joint Implants with significant improvement of grip strengths, DASH score and a 95% survival after 3 years (1-5 years).
