The Artelon CMC spacer compared with tendon interposition arthroplasty
Background and purpose The Artelon CMC spacer is design ed for surgical treatment of osteoarthritis ( OA ) in the carpometacarpal joint of the thumb ( CMC-I ) . Good results using this degradable device were previously presented in a pilot study . We now present results from a larger r and omized , controlled , multicenter study . Patients and methods 109 patients ( 94 females ) with a mean age of 60 ( 42–83 ) years , suffering from painful CMC OA , were included in the study at 7 centers in Sweden . The patients were r and omized to Artelon CMC spacer ( test , n = 72 ) or tendon arthroplasty ( control , n = 37 ) at a ratio of 2:1 . Perceived pain was recorded on a visual analog scale ( VAS ) before treatment and after 3 , 6 , and 12 months , when measuring maximal tripod pinch strength ( primary outcome measure ) . In addition , range of motion , radiographic findings , and functional testing were recorded pre- and postoperatively . Results Swelling and pain were more common in the test group and 6 implants were removed because of such symptoms . 5 of these patients did not receive antibiotics preoperatively according to the study protocol . In a per- protocol analysis , i.e. patients without signs of concomitant OA in the scaphoid-trapezium-trapezoid ( STT ) joint and those in the test group who received antibiotics , the mean difference in tripod pinch strength increase , adjusted for baseline , was 1.4 kg in favor of the test group ( not statistically significant ) . Statistically significant pain relief was achieved in both groups , with perceived pain gradually decreasing during the follow-up period . In the intention-to-treat analysis but not in the per- protocol analysis , significantly better pain relief ( VAS ) was obtained in the control group . Patient-perceived disability evaluated by the DASH question naire improved in both groups . Interpretation The Artelon CMC spacer did not show superior results compared to tendon interposition arthroplasty . Proper use of preoperative antibiotics and a thorough patient selection appear to be important for the results
