Arthroscopic synovectomy of the wrist

Role of Wrist Arthroscopy in Juvenile Inflammatory Arthritis

Background and Purposes  The wrist is the fourth most common joint to be involved in juvenile inflammatory arthritis (JIA), which is a common rheumatological condition affecting children. Wrist arthroscopy is well established in rheumatoid arthritis, but remains unexplored in JIA. The aim of this study is to investigate the role of wrist arthroscopy in JIA, with focus on those who are refractory to medical management. Methods  This is a prospective observational study, including consecutive patients with JIA undergoing arthroscopy between January 2016 and December 2020. Those over the age of 18 years and those with other rheumatological diagnoses were excluded. Data including pre-, intra-, and postoperative variables, demographics, and patient-reported outcomes were collated and are reported using standard measures. Results  A total of 15 patients underwent arthroscopy ( n  = 20 wrists). Synovitis was noted in all wrists on arthroscopy and synovectomy was performed in all cases. Other procedures were performed as indicated during the procedure. The median follow-up duration was 11.3 (interquartile range [IQR] 8.1-24.2) months. Median reduction of 4 (IQR 2.25-6) points on the Visual Analogue Score for pain on loading was noted postoperatively. Grip strength was improved in n  = 11/20 wrists and functional improvement was noted in n  = 18/20 wrists. Restriction of range of motion was achieved with a shrinkage procedure in patients with hypermobile joints. There were no postoperative complications, and no patients were lost to follow-up. Conclusion  In experienced hands, wrist arthroscopy is feasible, safe, and efficacious in the management of JIA, among patients who are refractory to medical management. Level of Evidence  This is a Level II study.

Arthroscopy-assisted bone grafting for the treatment of SNAC stage I without radial styloidectomy

To report the clinical and radiological outcomes of arthroscopic bone grafting and percutaneous K-wire fixation without radial styloidectomy in patients with scaphoid nonunion advanced collapse (SNAC). We retrospectively analyzed the records of 15 patients with SNAC who were treated with arthroscopic bone grafting and percutaneous K-wire fixation and subsequently followed up for a minimum of 1 year between November 2009 and March 2018. The clinical outcomes were evaluated by comparing the range of motion (ROM), grip strength, the modified Mayo Wrist Score, and visual analog scale (VAS) scores for pain, all of which were measured preoperatively and at the last follow-up. The radiologic outcomes were evaluated by comparing the scapholunate (SL) and radiolunate (RL) angles preoperatively and at the last follow-up. All 15 cases of nonunion were resolved. The average radiologic union time was 9.7 ± 1.2 weeks. The average VAS score increased from 5.7 ± 2.3 (range, 2 - 10) preoperatively to 1.3 ± 1.3 (range, 0 - 3) at the last follow-up (P < .05). The average modified Mayo wrist score increased from 58.3 ± 14.0 preoperatively to 80.0 ± 9.2 at the last follow-up (P < .05). The mean ROM of the wrist improved, but there was no statistical significance. At the last follow-up, the mean flexion and radial deviation on the affected side were significantly decreased, and the mean extension on the affected side was significantly improved compared to the normal side (P < .05). The mean preoperative SL and RL angles were 66 ± 11.9° and 7.2 ± 6.8°, respectively, and were decreased to 50.4 ± 7.5° and 6.4 ± 5.2°, respectively, at the last follow-up. The mean SL angle was significantly corrected (P = .01). Arthroscopic bone grafting and percutaneous Kerschner (K)-wire fixation without radial styloidectomy are considered to be very effective methods for correcting scaphoid deformities to treat SNAC stage I. However, caution may be needed during the surgery to prevent reductions in flexion and the radial deviation of the wrist.

[Hand surgery in the rheumatic hand-novel and established aspects]

BACKGROUND

Hand surgery of the rheumatoid hand has undergone significant changes mostly as a result of biologicals and biosimilars.

OBJECTIVE

The significance of established and innovative operative procedures in the modern treatment of the rheumatoid hand is elaborated and a subsumption of local interventional options in this context is carried out.

METHODS

The analysis, evaluation and discussion of the literature and expert recommendations are presented.

RESULTS

With the consistent use of modern antirheumatic drugs the destruction and deformation of the wrist and hand occur more slowly and less severely. The hand surgeon can therefore operate more selectively and focus on less pathologies at the same time. Up to the present many of the operative techniques described by the pioneers of modern hand surgery are still powerful tools. Most of the considerations about the correction of the disturbed biomechanics and about the reconstitution of stability and the range of motion are still valid. The combination of arthroscopic synovectomy and radiosynoviorthesis of the wrist seems to show promising results.

CONCLUSION

Modern treatment of the rheumatoid hand is a multidisciplinary challenge. Rheumatologists, nuclear medicine physicians and hand surgeons together can achieve excellent results. A consistent medication, an early operative intervention if necessary and systematic integration of nuclear medicine physicians into the therapeutic process enable preservation of the long-term function of the hand as the main tool in daily life.

Wrist Arthroscopy in Juvenile Idiopathic Arthritis: A Review of Current Literature and Future Implications

Introduction  Juvenile Idiopathic Arthritis (JIA) is the most common rheumatological condition in children and frequently affects the wrist. The roles for wrist arthroscopy and arthroscopic synovectomy (AS) in JIA are unclear. Our aim was to find the current evidence supporting its use. Methods  Systematic literature review of relevant publications from 1990 to present in the Cochrane Library, Clinical Knowledge Summaries, DynaMed, PEMSoft, NICE Guidance, MEDLINE, EMBASE, and PubMed. Results  We found no publications detailing the use of arthroscopy or AS specifically in patients with JIA involving the wrist. There is evidence that AS reduces pain, improves function, and induces remission in patients with rheumatoid arthritis resistant to medical management. Discussion and Conclusion  Although there is paucity in evidence for the use of AS in the wrists of patients with JIA, studies suggest it to be safe and effective, and could be applied to patients with refractive JIA. It is possible that early identification of patients suffering from JIA with extensive joint destruction and little symptoms could benefit from AS, delaying joint destruction and preserving function.

Advances in hand and wrist arthroscopy

Hand and wrist arthroscopy has gained popularity over the past few decades. Arthroscopy is a valuable diagnostic tool in cases where clinical and radiographic findings do not show a clear picture of the patient's pathologic condition. Arthroscopy also allows care providers to perform therapeutic interventions in a less invasive manner than would have been possible with a standard open approach. Over the past three decades, there have been substantial advances in the techniques and outcomes in hand and wrist arthroscopy. With this article, the authors aim to introduce the application of newer arthroscopic techniques in the hand and wrist that may be of diagnostic and/or therapeutic value.

Long-term results of arthroscopic wrist synovectomy in rheumatoid arthritis

PURPOSE

To investigate the effects of arthroscopic wrist synovectomy on the clinical course of rheumatoid arthritis in a large series with long-term follow-up.

METHODS

We performed arthroscopic synovectomy on 56 wrists in 49 patients with rheumatoid arthritis. At a mean follow-up of 7.9 years (range, 5-12 y), we evaluated pain and patient satisfaction using a visual analog scale and assessed overall function using the Mayo wrist score. Radiographic stage was graded according to Larsen stage. We determined clinical outcomes on the recurrence of wrist synovitis, which we evaluated by symptoms of pain and swelling and physical examination. Preoperative variables were statistically analyzed to find factors that could influence the results.

RESULTS

The mean visual analog scale score for wrist pain decreased from 6.3 to 1.7, and the mean Mayo wrist score (evaluated in 39 wrists) improved from 48 (range, 5-70) to 76 (range, 55-100). The mean visual analog scale score for patient satisfaction was 7.9. At final follow-up, synovitis was controlled in 42 wrists (75%) and recurred in the others. The mean Larsen stage progressed from 2.2 to 3.3. Analysis of preoperative variables revealed no factors that significantly affected clinical outcomes in terms of sex, age, duration of wrist symptom, preoperative serologic inflammatory markers, or Larsen stage.

CONCLUSIONS

Arthroscopic synovectomy of the wrist can provide pain relief and functional improvement with control of synovitis in 75% of rheumatoid wrists that have not responded to medication.
