ABSTRACT
OBJECTIVES: We aimed to compare the outcomes of joint-preserving surgery for hallux valgus deformities with minimal erosion of the metatarsophalangeal joint in rheumatoid patients with non-rheumatoid controls, and to determine the prognostic factors of recurrence in rheumatoid patients.
METHODS: A total of 18 rheumatoid patients (20 feet, Group I) and 35 non-rheumatoid patients (39 feet, Group II) were included. The mean follow-up was 29.6 months. Radiographic and clinical outcomes were compared. To identify the prognostic factors for recurrences in rheumatoid patients, subgroup analyses were done in Group I.
RESULTS: Most of the outcomes showed favorable results in both groups. However, Group II had better results in hallux valgus angle (HVA) (15.9° vs. 7.9°, p < 0.001), and in sesamoid position (p = 0.040) at final follow-up. Group I showed higher recurrence rate (50% vs. 0%). The final American Orthopaedic Foot and Ankle Society score was better in Group II (82.1 vs. 90.7, p = 0.014). The large preoperative HVA, non-performance of Akin osteotomy, and insufficient reduction of sesamoid position were related to recurrence in rheumatoid patients.
CONCLUSIONS: Joint-preserving surgery for hallux valgus deformities in rheumatoid forefoot deformity showed favorable results in mid-term follow-up; however, it should be warned of possible recurrent deformities.
