Objective  To compare the effectiveness of talonavicular-cuneiform joint fusion with iliac bone grafting and without bone grafting in the treatment of Müller-Weiss diseases (MWD). Methods  The clinical data of 44 patients (44 feet) with MWD who received talonavicular-cuneiform joint fusion between January 2017 and November 2022 and met the selection criteria was retrospectively analyzed. Among them, 25 patients were treated with structural iliac bone grafting (bone grafting group) and 19 patients without bone grafting (non-bone grafting group). There was no significant difference (P>0.05) in age, gender composition, body mass index, disease duration, affected side, Maceira stage, and preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, anteroposterior/lateral Meary angle, and Pitch angle between the two groups. Operation time, operation cost, and postoperative complications were recorded in the two groups. AOFAS and VAS scores were used to evaluate the function and pain degree of the affected foot. Meary angle and Pitch angle were measured on the X-ray film, and the joint fusion was observed after operation. The difference (change value) of the above indexes before and after operation was calculated for comparison between groups to evaluate the difference in effectiveness. Results  The operation was successfully completed in both groups, and the incisions in the two groups healed by first intention. The operation time and cost in the bone grafting group were significantly more than those in the non-bone grafting group (P<0.05). All patients were followed up. The median follow-up time was 41.0 months (range, 16-77 months) in the non-bone grafting group and 40.0 months (range, 16-80 months) in the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case, internal fixation stimulation in 2 cases, and pain at the iliac bone harvesting area in 1 case of the bone grafting group. There was skin numbness of the medial dorsalis of the foot in 1 case and muscle atrophy of the lower limb in 1 case of the non-bone grafting group. There was no significant difference in the incidence of complications between the two groups (P>0.05). At last follow-up, the AOFAS scores of the two groups significantly improved when compared with those before operation, while the VAS scores significantly decreased, the anteroposterior/lateral Meary angle and Pitch angle significantly improved, and the differences were significant (P<0.05). There was no significant difference in the change values of outcome indicators between the two groups (P>0.05). There was no delayed bone union or bone nonunion in both groups, and joint fusion was achieved at last follow-up. Conclusion  In the treatment of MWD, there is no significant difference in effectiveness and imaging improvement of talonavicular-cuneiform joint fusion combined with or without bone grafting. However, non-bone grafting can shorten the operation time, reduce the cost, and may avoid the complications of bone donor site.
