Joint replacement is an established method in the treatment of destroyed, p
ainful, proximal interphalangeal joints. A palmar approach was used in whic
h the main collateral ligaments were preserved, allowing immediate active r
ehabilitation with enhanced primary lateral stability. Fifty-nine proximal
interphalangeal joint silicone arthroplasties in 38 patients with a minimum
followup of 12 months were reviewed, Thirty-eight of the 59 joints had imp
lantation from a palmar approach and 21 joints from a dorsal approach. The
tno groups were well-matched in terms of indication, preoperative range of
motion, and patient age. No significant increase in the range of motion was
found in either of the patient groups, with an overall average range of mo
tion of 51 degrees postoperatively. There was also no significant differenc
e in the postoperative stability in the two patient groups. The choice of s
urgical approach at the proximal interphalangeal joint level for the silast
ic type of implants does not appear to be important. With more sophisticate
d types of implants in which the integrity of the collateral ligaments is c
rucial, a palmar approach might be beneficial.
