As RA medications have evolved over the past 30 years, the surgical indications and techniques for RA joint deformities have changed. The aim of this review article is to summarize the recent trend of surgery for rheumatoid hand\/finger deformities in previous reports and to present our recent surgical methods and outcomes for these deformities. A typical hand and finger deformity caused by RA is ulnar deviation, which is mainly caused by joint laxity and dislocation of the metacarpophalangeal joints, in addition to extensor tendon dislocation and\/or wrist joint deformity. Although the incidence of hand\/finger deformity and ulnar deviation caused by RA is decreasing due to advances in RA medications, patients with long-term RA or those with difficult-to-treat RA may still develop hand\/finger deformity and ulnar deviation. If the hand\/finger deformity is mild, it can be reduced manually, and conservative treatment with orthoses or splints may be required. If joint pain is severe despite good medical control of RA, or if the patient hopes to improve the appearance of the hand or fingers, surgical intervention is required. If there is only subluxation of the joints, which preserves their structure, reconstruction with only soft tissue surgery may be required. For example, for swan-neck deformity and boutonni\u00e9re deformity, two of the most typical finger deformities due to RA, when the joint structures are almost intact and can be corrected manually, we opt for a surgical procedure that involves only soft tissue manipulation without the use of prosthetic implants. For ulnar deviation without joint destruction, we usually use a soft tissue-only surgical procedure. Our results have shown that the soft tissue-only surgery for ulnar deviation is as effective as joint replacement with implants. If the destruction of the joint has occurred and its dislocation\/subluxation cannot be reduced manually, implant arthroplasty becomes necessary. If the joint destruction is severe, only intra-articular arthrodesis is required. In the era when RA can be controlled by medication, the hand surgeon should not overlook the change in the stage of the rheumatoid hand and should perform surgical intervention via the appropriate surgical method.<\/jats:p>","DOI":"10.3390\/jcm14020319","type":"journal-article","created":{"date-parts":[[2025,1,7]],"date-time":"2025-01-07T07:42:19Z","timestamp":1736235739000},"page":"319","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Trends in Rheumatoid Hand Surgery: Indications, Techniques, and Outcomes"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6757-897X","authenticated-orcid":false,"given":"Masanori","family":"Nakayama","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, School of Medicine, International University of Health and Welfare (IUHW), Narita Hospital, 852 Hatakeda, Narita 286-8520, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4537-6754","authenticated-orcid":false,"given":"Yasuhiro","family":"Kiyota","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soichiro","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, School of Medicine, International University of Health and Welfare (IUHW), Narita Hospital, 852 Hatakeda, Narita 286-8520, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2324-3780","authenticated-orcid":false,"given":"Mitsuru","family":"Yagi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, School of Medicine, International University of Health and Welfare (IUHW), Narita Hospital, 852 Hatakeda, Narita 286-8520, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1016\/j.autrev.2004.09.002","article-title":"Epidemiology of adult rheumatoid arthritis","volume":"4","author":"Alamanos","year":"2005","journal-title":"Autoimmun.
