Reconstruction of the rheumatoid hand

Swan-Neck and Boutonniere Deformity in Rheumatoid Hand

Rheumatoid arthritis (RA) is an inflammatory disease for which the exact cause is unknown. It is an autoimmune disorder that primarily affects such joints which allows free movement in different directions, but also has many other severe complications related to mortality. On the other hand, this disease is responsible for digital deformities, arising out of a combination of synovitis, intrinsic muscles, and extrinsic tendons impairment, ligament rupture, joint dislocation, and final ankylosis. Articular swelling due to synovial proliferation is the first manifestation, but later deformity, subluxation, instability, contracture, and ankyloses can be visible with joint degeneration. Rupture of the capsular and tendon often happens at the wrist. Intrinsic and extrinsic muscle contractures are associated with typical hand joint malalignment. Osteoarthritic involvement has changed with the introduction of biologic disease-modifying anti-rheumatic drugs (bDMARD).

Arthroscopic Synovectomy of the Wrist in Patients With Rheumatoid Arthritis: A Systematic Review of the Current Literature

BACKGROUND

Rheumatoid arthritis (RA) of the wrist can lead to loss of wrist function and progressive joint destruction if inadequately treated. Arthroscopic synovectomy of the wrist may prove a valuable treatment for local inflammation.

OBJECTIVE

The aim of this study was to perform a systematic review evaluating functional outcomes and pain following arthroscopic synovectomy of the wrist in RA patients.

METHODS

A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) guidelines. MEDLINE, EMBASE, The Cochrane Library, Web of Science, and Google Scholar were searched for studies describing pain or functional outcomes following arthroscopic synovectomy of the wrist in RA patients (CRD42021270846). Risk of bias was assessed using the Methodological Index for Non-Randomized Studies. Data collection included patient characteristics, pain scores, wrist function questionnaires, secondary surgery, and complications.

RESULTS

Six noncomparative cohort studies were included, with a total of 153 arthroscopic synovectomies. Disease duration of RA ranged from 32 to 89 months, and radiographic progression was mild to moderate. The Methodological Index for Non-Randomized Studies scores ranged from 8 to 10 out of 16. Mean follow-up ranged from 21 to 95 months. Improvements were seen in pooled mean visual analog scale pain score (from 7.7 to 2.2, p < 0.05), pooled mean Modified Mayo Wrist Score (from 43.3 to 70.4, p < 0.05), and the Disability of the Arm, Shoulder, and Hand (from 67.5 to 36.5, p < 0.05). Two complications occurred, and 5 patients required secondary surgery.

CONCLUSIONS

There is limited evidence suggesting that arthroscopic synovectomy of the wrist improves wrist function and pain in patients with RA, with few complications. In centers with arthroscopic expertise, it can be considered as a treatment option.

Applying evidence in the care of patients with rheumatoid hand and wrist deformities

The traditional approach in managing rheumatoid hand deformities is based on the individual surgeon's experiences. In the current era of evidence-based medicine, formulating treatment for the rheumatoid hand fits perfectly within the framework of evidence-based medicine by leveraging the best evidence from the literature, incorporating surgeons' experience and considering patients' preferences. In this Special Topic article, we use a case example to illustrate how evidence-based medicine can be practiced within the framework of treating rheumatoid hand deformities by distilling the best evidence from the literature to guide surgeons in a rational approach for treating this common condition.
