THIS COMPARATIVE STUDY AIMS TO REPORT THE EXPERIENCE OF THE AUTHORS WITH FOUR-CORNER FUSION USING A RADIOLUCENT LOCKING DORSAL CIRCULAR PLATE (XPODE®, TRIMED INC., SANTA CLARITA, CA, US), AND TO COMPARE IT WITH ANOTHER FIXATION METHOD (3.0-MM CANNULATED HEADLESS COMPRESSION SCREWS [HCSS], SYNTHES, SOLOTHURN, SWITZERLAND) REGARDING CONSOLIDATION, FUNCTIONAL OUTCOMES, AND COMPLICATION RATES. IN TOTAL, 17 SUBJECTS WERE INCLUDED; 8 PATIENTS WERE OPERATED ON FROM 2010 TO 2012 WITH OSTEOSYNTHESIS USING 2 HCSS, (3.0 MM CANNULATED HEADLESS COMPRESSION SCREWS [HCSS], SYNTHES, SOLOTHURN, SWITZERLAND) AND 9 PATIENTS WERE OPERATED ON BETWEEN 2011 AND 2014 WITH A RADIOLUCENT LOCKING DORSAL CIRCULAR PLATE (XPODE®, TRIMED INC., SANTA CLARITA, CA, US), MADE OF A SYNTHETIC POLYMER CALLED POLYETHER-ETHER-KETONE (PEEK). THE MEAN AGE IN THE FIRST GROUP WAS 45 YEARS (RANGE: 32¿ 64 YEARS) AND THE AVERAGE FOLLOW-UP PERIOD WAS OF 18 MONTHS. THIS GROUP CONSISTED OF SIX MEN AND TWO WOMEN. IN THE SECOND GROUP, THE MEAN AGE WAS 40 YEARS (RANGE: 18 62 YEARS). THIS GROUP CONSISTED OF EIGHT MEN AND ONE WOMAN. THE AVERAGE FOLLOW-UP PERIOD WAS OF 12 MONTHS. THE FOLLOWING COMPLICATIONS WERE REPORTED: FAILURE OF THE OSTEOSYNTHESIS. A CASE OF OSTEOLYSIS, WHICH DID NOT RESULT IN NON-UNION. A CLINICALLY-ASYMPTOMATIC PATIENT PRESENTED MIGRATION OF ONE OF THE CAPITATE-LUNATE SCREWS ON THE CONTROL RADIOGRAPH TAKEN AT SIX MONTHS; SINCE THERE WAS A RISK OF INVOLVEMENT OF THE RADIOCARPAL ARTICULAR SURFACE, A NEW SURGERY WAS REQUIRED FOR THE REMOVAL OF THE OSTEOSYNTHESIS MATERIAL NINE MONTHS AFTER THE FIRST PROCEDURE. FAILURE OF THE OSTEOSYNTHESIS. A CASE OF OSTEOLYSIS, WHICH DID NOT RESULT IN NON-UNION, WITH AND RADIOLUNATE JOINT WEAR. PATIENT PRESENTED PERSISTENT PAIN THAT DID NOT SUBSIDE WITH REHABILITATION, SO IT WAS DECIDED TO PERFORM A TOTAL WRIST ARTHRODESIS, WHICH IS STILL PENDING. THE MEAN FLEXION-EXTENSION ROM AMONG THE HCS GROUP WAS OF 68°, WITH AN AVERAGE FLEXION OF 38.1° (RANGE: 20°¿45°) AND AN AVERAGE EXTENSION OF 29.7° (RANGE: 20°¿40°).
