Proximal interphalangeal joint arthroplasty through a volar approach preserves
the extensor apparatus, which allows for early active rehabilitation. Here, we
report on the results of 28 silicone implants in patients suffering from
rheumatoid arthritis (12 joints) or osteoarthritis (16 joints) with a mean
follow-up of 39 months. Pain was reduced significantly after arthroplasty. Range
of motion increased significantly by 29 degrees with a mean postoperative value
of 58 degrees ; the mean extension deficit was reduced from 14 degrees to 5
degrees . There were 18 cases of preoperative ulnar drift with a mean value of 13
degrees , compared with 13 cases postoperatively with a mean value of 7 degrees .
Three cases (10%) of implant fracture were noted on the radiology reports. The
mean DASH score at follow-up was 35/100. Immediate active mobilization led to
significant shortening in recovery time. The improvement in mobility and
extension seems to be higher than that obtained with other approaches.
Clinodactyly remains problematic no matter the type of arthroplasty.
