Although metaphyseal ulnar shortening osteotomy (MUSO) is safer for the treatment of ulnar impaction syndrome (UIS) than diaphyseal ulnar shortening osteotomy (DUSO), DUSO is widely used for UIS treatment.
To evaluate the effectiveness of DUSO and MUSO for UIS treatment and determine the factors that should be considered when choosing surgical treatment for UIS.
Articles comparing the effectiveness of DUSO and MUSO for UIS treatment were systematically retrieved from MEDLINE (Ovid), PubMed, EMBASE, and Cochrane Library. The demography, incidence of complications, secondary operation rate, postoperative DASH score, wrist pain on the visual analogue scale, and grip strength improvement were also evaluated. In addition, the correlation between the improvement of grip strength and the shortening of osteotomy length of ulna was analyzed. The outcome of the patient was discontinuous, and the odds ratio, risk ratio (RR), and 95%CI were calculated and analyzed via RevMan5.3 software.
Six studies, including 83 patients receiving MUSO (experimental group) and 112 patients receiving DUSO (control group), were included in the meta-analysis. The second operation rate was significantly higher after DUSO than after MUSO. The DASH scores were slightly lower in the MUSO group than in the DUSO group. The patients receiving MUSO had slightly better pain relief effect than patients receiving DUSO. However, the incidence of complications and improvement of grip strength were not significantly different between the two groups.
Although DUSO and MUSO provide similar effects for UIS, MUSO is associated with a lower secondary operation rate, slightly lower postoperative DASH scores and slightly better pain relief effect than DUSO, indicating that MUSO can effectively be used for UIS treatment.
Core Tip: Ulnar impaction syndrome (UIS) is caused by overload of the ulnar wrist joint. This is the common cause of ulnar wrist pain. UIS is related to static or dynamic lateral positive change. If not treated in time, it may lead to the erosion and perforation of the triangular fibrocartilage complex, as well as the degeneration of the triangular, Lunate or ulnar head cartilage. Therefore, the basic treatment of UIS includes mechanical decompression of the overloaded ulnar wrist joint by reducing the ulnar variation. There are many surgical treatments that can reduce the excessive pressure on the ulnar side of the wrist joint, including diaphyseal ulnar shortening osteotomy (DUSO), thin section resection and metaphyseal ulnar shortening osteotomy (MUSO). The Wafer resection site of the distal ulna belongs to MUSO. Compare the effect of DUSO and MUSO ulnar shortening methods. In fact, both of these operations have specific advantages and disadvantages. It should be clear whether the treatment choice of UIS patients depends on the preferences of surgeons.
