Total wrist arthroplasty is a challenging procedure for wrist joints severely destroyed by rheumatoid arthritis. The most common postoperative complication of total wrist arthroplasty is the loosening of the carpal component. Revision surgeries for failed total wrist arthroplasties can be complicated owing to severe bone loss and concomitant soft-tissue problems. Here we report a case (68-year-old woman with a history of rheumatoid arthritis for 24 years) of severe aseptic loosening of semi-constrained total wrist arthroplasty and its salvage surgery. During the primary arthroplasty procedure, severe instability at the second through fifth carpometacarpal joints was observed, and arthrodesis of these joints was required. The radiographs obtained nine months after surgery showed loosening of the carpal component. Subsequently, she suffered a stroke, resulting in a loss of follow-up, and higher stress was loaded on her upper extremities during standing and walking. In the radiograph taken at her revisit 25 months after the primary surgery, the subsidence of the carpal component progressed, and loosening of the radial component was observed. Total wrist arthrodesis was performed using a bulk bone allograft of the femoral head, combined with a penetrating Wrist Fusion Rod®. Rapid bone union was achieved without soft tissue irritation. We conclude that wrist arthrodesis with a bulk bone allograft combined with an intramedullary nail is a reasonable option for failed total wrist arthroplasty.

ABSTRACT

Objective

We retrospectively reviewed the records of rheumatoid arthritis (RA) patients who underwent orthopaedic surgery to examine the influence of the perioperative use of Janus kinase (JAK) inhibitors on early postoperative complications.

Patients and Methods

Thirty-two patients with RA under disease control with JAK inhibitors who underwent 49 orthopaedic procedures were included in the study. Patient records after surgery were investigated for surgical site infection (SSI), delayed wound healing (DWH), a flare-up of the disease, preoperative and postoperative absolute lymphocyte counts (ALCs), venous thromboembolism, and other postoperative complications.

Results

JAK inhibitors were continued during the perioperative period in 31 procedures. In the remaining 18 procedures, JAK inhibitors were discontinued perioperatively with a mean discontinuation period of 2.4 days. No instances of SSI were identified in any patient during at least 90 days’ follow-up, while DWH was seen in one patient. Disease flare-up was noted in two patients after 3 and 9 days of discontinuation of JAK inhibitors, respectively. The ALCs significantly decreased on postoperative Day 1 (P &lt; .0001), and there was a significant correlation between pre- and post-one-day ALCs (r = 0.75, P &lt; .0001).

Conclusion

JAK inhibitors seem to be safe during the perioperative period of orthopaedic surgery.

＜文献概要＞Headline 1 関節リウマチでは,薬物療法が適切に行われたうえで,残存する関節症状に対する非薬物療法が検討される.関節注射やリハビリテーション,装具療法などの保存療法が無効な場合は手術治療が検討される.2 関節破壊・変形が軽度な段階から高度に進行した段階まで,様々な手術方法の適応があるが,関節構造を温存し,より高度な機能再建を求めるならば早期に手術治療を行ったほうがよい.3 合併する腱断裂,絞扼性神経障害や脊椎脊髄障害などの進行にも注意する必要があり,発症・進行が疑われる場合は整形外科へのコンサルトが必要である.4 手術治療のタイミングを逸さないためには,手術適応の判断だけではなく保存的治療や経過観察も含めた内科・整形外科の連携体制がとられていることが望ましい.
