PURPOSE: Midcarpal fusion is a reliable treatment for posttraumatic carpal collapse in the short or midlong term. The long-term results remain, however, unclear. The objective of this study was to assess the long-term clinical outcome but also the incidence of an arthrosis of the radiolunate joint or an ulnar translocation after excision of the scaphoid.
METHOD AND MATERIAL: 37 patients after midcarpal fusion were reexamined after an average follow-up of 97 months clinically and radiologically.
RESULTS: The average range of motion from extension to flexion was 62 degrees, the average grip strength changed from 69 % of the opposite side before surgery to 80 % after surgery. Pain in the verbal analogue scale improved from 2.7 preoperatively to 1.7 postoperatively. The Krimmer wrist score was 72, whereas 28 patients (76 %) reached a good or excellent result. The mean DASH score was 24 points. At the X-rays, ten patients (27 %) showed an arthrosis of the radiolunate joint and/or an ulnar translocation. Differences in clinical results between the groups with or without X-ray pathology were not statistically significant. From 107 patients with a midcarpal fusion in the time of interest, seven (6.5 %) had to be converted into wrist arthrodesis because of ongoing pain.
CONCLUSION: Also in the long-term the motion-sparing midcarpal fusion offers a functional advantage over wrist arthrodesis.
