PURPOSE: In the following article we present our results with a cemented titanium/polyethylene prosthesis.
PATIENTS AND METHODS: The SR (TM)-PIP-prosthesis from the firm SBI (©) (formally Avanta (©)) was implanted in 39 patients in our clinic from 2001-2007. In all, we were able to follow-up in a retrospect clinical study 32 patients with 39 proximal interphalangeal joint prostheses. We examined the range of motion, the strength and looked for deformities. The patients had to fill in a questionnaire before examination about their pain and limitation in daily life. We also performed X-rays of the operated fingers.
RESULTS: The postoperative range of motion was about 67°. The strength mean value was 24.7 kg. 4 patients needed surgical revisions, in one case due to loosening of the proximal part of the prosthesis. 2 patients also received a tenoarthrolysis because of extension deficits and one patient because of a swan-neck deformity. We noted 7 swan-neck deformities and in 7 cases we found implant loosening of the proximal part of the prothesis. The postoperative Quick-DASH score was about 32.2 and showed a good result. All participants reported a marked improvement in pain reduction.
CONCLUSION: These positive results, the reduction of pain and the satisfaction of the patients advocate the use of this prosthesis for the proximal interphalangeal joint. The postoperative ROM is comparable to those of other prostheses. Concerning implant loosening and swan-neck deformity, these results still offer room for improvement. Critical judgement and further development of the prosthesis design, the operation technique and the instrumentation are required to further optimise the results.
