RESUMEN
Introduction: Juvenile idiopathic arthritis (JIA) is an inflammatory arthritis of childhood that can lead to pain and dysfunction of the hands. In severe progressive cases, in which medical treatment does not result in symptom improvement, limited options are available. Metacarpophalangeal (MCP) joint arthroplasty remains a standard surgical treatment for inflammatory arthritis of the MCPmetacarpophalangeal joints in adults; however, no reports exist about its use in children or for JIA. Case Presentation: We present two cases of MCP joint arthroplasty in patients with severe progressive JIA. The first patient presented at 21 years old with increasing pain and limited use of her right hand and underwent MCP arthroplasty using a pyrocarbon implant. The second patient presented at 14 years old with severe pain, contractures, subluxations, and the inability to use her right hand, subsequently undergoing MCP replacement with a silicone-based implant. The joint replacements resulted in pain relief and improvement of hand function for both patients, though the pyrocarbon implants had poor radiographic outcomes at 7 years follow- up, while the silicone implants had limited functional improvement. Conclusions: MCPMetacarpophalangeal joint replacement may be considered in patients with severe inflammatory arthritis to relieve pain and/or to extend functional use of the fingers and hands. In these cases, silicone arthroplasty radiographically fared better than pyrocarbon.

We retrospectively reviewed and compared the outcomes and complications associated with 81 single digit and 168 multi-digit proximal interphalangeal joint arthroplasties performed from 1998 to 2012 in 136 patients. Clinical outcomes were assessed with an average follow-up of 5.3 years for single digit and 5.9 years for multi-digit proximal interphalangeal joint arthroplasty. Comparing single versus multi-digit proximal interphalangeal joint arthroplasty, the reoperation-free survival was 67% and 68% at 5 years and 56% and 67% at 10 years, respectively. Furthermore, in comparison of single versus multi-digit proximal interphalangeal joint arthroplasty, the revision-free survival was 80% and 86% at 5 years and 80% and 85% at 10 years, respectively. Given the similar, or even slightly improved, rates of complications, reoperation, and revision surgery, proximal interphalangeal joint arthroplasty performed on multi-digits results in no worse outcomes compared with single digit proximal interphalangeal joint arthroplasty. LEVEL OF EVIDENCE: IV.

Arthritis of the hand can result from inflammatory arthritis, osteoarthritis (OA), or be posttraumatic and can cause pain and debilitation. Arthroplasty serves as 1 surgical option in the surgical management of arthritis and aims to create a pain-free joint with preservation of motion. Although implant arthroplasty of the proximal interphalangeal (PIP), metacarpophalangeal (MCP), and trapeziometacarpal (TMC) joints predictably produce pain relief and high satisfaction, it has historically suffered from high rates of complications. The hinged silicone prosthesis was 1 of the early implants and, in many cases, remains the gold standard. However, problems with deformity correction, implant fracture, and synovitis remain. Implants made of alternative materials such as metal-plastic and pyrocarbon have evolved; however, survivorship and reoperation rates remain a concern. This review details the evolution and current options available for small joint implant arthroplasty involving the MCP, PIP, and TMC joints.

BACKGROUND: Total wrist arthroplasty (TWA) can relieve pain and preserve some wrist motion in patients with advanced wrist arthritis. However, few studies have evaluated the risks and outcomes associated with periprosthetic fractures around TWAs. QUESTIONS/PURPOSES: (1) What is the risk of intraoperative and postoperative fractures after TWAs? (2) What factors are associated with increased risk of intraoperative and postoperative fracture after TWAs? (3) What is the fracture-free and revision-free survivorship of TWAs among patients who sustained an intraoperative fracture during the index TWA? METHODS: At one institution during a 40-year period, 445 patients underwent primary TWAs. Of those, 15 patients died before 2 years and 5 were lost to followup, leaving 425 patients who underwent primary TWAs with a minimum of 2-year followup. The primary diagnosis for the TWA included osteoarthritis ([OA] 5%), inflammatory arthritis (90%), and posttraumatic arthritis (5%). Indications for TWA included pancarpal arthritis combined with marked pain and loss of wrist function. The mean age of the patients was 57 years, BMI was 26 kg/m2, and 73% were females. Six different implants were used during the 40-year period. Mean followup was 10 years (range, 2-18 years). RESULTS: Intraoperative fractures occurred in nine (2%) primary TWAs, while postoperative fractures occurred after eight (2%) TWAs. After analyzing demographics, comorbidities, and surgical factors, intraoperative fractures were found to be associated with only age at surgery (hazard ratio [HR], 1.10; 95% CI, 1.03-1.20; p = 0.006) and use of a bone graft (HR, 5.80; 95% CI, 1.18-23.08; p = 0.03). No factors were found to be associated with increased risk of postoperative fractures; specifically, intraoperative fracture was not associated with subsequent fracture development. The 5-, 10-, and 15-year Kaplan-Meier survival rates free of postoperative fracture were 99%, 98%, and 95%, respectively. The 5- and 10-year revision-free survival rates after intraoperative fracture were 88% and 88%, respectively, compared with 84% and 74% without an intraoperative fracture (p = 0.36). Furthermore, the survival-free of revision surgery rates for aseptic distal loosening at 5 and 10 years were 88% and 88%, respectively, compared with 93% and 87% without a fracture (p = 0.85). CONCLUSIONS: Intraoperative fractures occur in approximately 2% of TWAs. These fractures do not appear to affect long-term implant survival or risk of fracture. Patient age and the need for bone graft were the only factors in the risk of intraoperative fractures. Postoperative fractures also occur in 2% of TWAs, but often result in revision surgery. LEVEL OF EVIDENCE: Level III, therapeutic study.
