The TACTYS(R) implant is a new anatomic gliding articular and modular prosthesis
for the proximal interphalangeal (PIP) joint. We report preliminary results with
a minimum follow-up of 2 years. Twenty-two patients with a mean age of 63 years
were operated on at a single center by two senior hand surgeons. Indications were
painful and stiff PIP joints.
The joint damage was caused by osteoarthritis (18
cases), post-traumatic arthritis (3) and rheumatoid arthritis (1). All prostheses
were implanted through a dorsal mid-line transtendinous approach. Postoperative
active and passive range of motion in flexion and extension was performed
immediately with a protective splint for 2weeks. All patients were evaluated
(pain, range of motion, strength, function, X-rays) with a mean follow-up of
34months (range 24-50). Pain decreased from 6.5 preoperatively to 1.9
postoperatively on a VAS scale. Flexion-extension range of motion increased from
39 degrees preoperatively to 58 degrees postoperatively. Grip strength was 21kg
preoperatively and 25kg postoperatively. Pinch strength was 3kg preoperatively
and 5kg postoperatively. Functional QuickDASH and PRWE scores were significantly
improved at the last follow-up. Four patients were reoperated on: dorsal
tenoarthrolysis in 3 cases and volar osteophyte removal in 1 case. All implants
were still in place at the last follow-up. On X-rays, there were no signs of
implant migration or loosening. The modularity of the prosthesis seems to be this
implant's greatest advantage. The TACTYS(R) prosthesis is a reliable alternative
to other conventional PIP implants.
