Concerns about implant durability and technical difficulty continue to make total wrist arthroplasties a specialized procedure with a narrow scope of indications. As a result, more routinely performed total or partial wrist arthrodesis continues to maintain popularity over arthroplasty. However, wrist motion preservation is undoubtedly preferable for patients and current literature is trending to more favorable outcomes for total wrist arthroplasties. In the setting of the evolving role of wrist arthroplasties in clinical practice, it is important to focus on providing hand surgeons a practical approach to incorporating total wrist arthroplasty into the treatment toolbox available to them when treating patients with painful wrist arthritis.

Background: The purpose of this study was to investigate the outcomes of surface replacement arthroplasty (SRA) for noninflammatory arthritis of the metacarpophalangeal (MCP) joint., Methods: Records from 20 SRAs performed between 1995 and 2017 in 17 patients with noninflammatory arthritis affecting the MCP joint were retrospectively reviewed. The mean follow up was 6.6 years., Results: Three arthroplasties (15%) underwent 4 revision operations. The 2-, 5-, 10-, and 15-year rates of survival from surface replacement implant revision were 90%, 90%, 79%, and 79%, respectively. Major complications occurring in revised joints included arthrodesis (n = 1) and amputation (n = 1). The overall reoperation rate was 35%. The 2-, 5-, 10-, and 15-year rates of overall reoperation-free survival were 75%, 69%, 60%, and 60%, respectively., Conclusions: Pain ratings and MCP arc of motion significantly improved following arthroplasty. Metacarpophalangeal SRA for noninflammatory arthritis can improve arc of motion and pain. Revision is uncommon; however, 1 in 3 joints requires reoperation.

Background: Radioscapholunate (RSL) fusion is performed for painful radiocarpal arthritis that is typically posttraumatic or inflammatory in nature. The purpose of this study was to determine whether patients with inflammatory conditions undergoing RSL fusion had comparable outcomes as those with posttraumatic arthritis and to determine factors impacting union., Methods: This was a retrospective review of all RSL fusions over a 25-year period. Demographic information, wrist range of motion, postoperative complications, and surgical technique, including presence or absence of resection of distal scaphoid pole, data were collected. Radiographs were examined for evidence of healing of the RSL fusion site as well as development of midcarpal arthritis., Results: Fifty-six patients underwent RSL fusion. Eight patients required revision of radiocarpal arthrodesis for painful nonunion. The fusion rate was 85.7%, and median 25 th to 75th percentile (time to healing was 4.0 3.2-5.2) months. There were no differences in time to or rate of union by inflammatory arthropathy status. Grip strength increased significantly and pain decreased significantly with surgery. Union rate was 90% with the use of K-wires, screws, or staples, which was significantly greater than plates, fusion cups, or multiple implant types. The use of autologous bone graft significantly decreased the rate of nonunion and significantly decreased time to union by 3 months compared to allograft alone. Extension was significantly improved with scaphoid distal pole resection versus without distal scaphoid pole resection., Conclusions: Radioscapholunate (RSL) fusion is an effective treatment for radiocarpal arthritis but has high nonunion rates. Fixation with K-wires, screws, or staples and use of autograft confers improved union rate.

Thumb arthritis frequently is managed nonoperatively with activity modification, orthotic use, anti-inflammatory medications (oral and/or topical), and intra-articular injections. This article reviews the current literature and touches on novel modalities and future directions in the conservative treatment of thumb arthritis., (Copyright © 2021 Elsevier Inc.

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., (Copyright © 2017. Published by Elsevier Inc.)

Purpose: To assess the incidence of and identify risk factors for intraoperative periprosthetic fractures during primary and revision metacarpophalangeal (MCP) joint arthroplasty., Methods: Through our institutional Joint Registry Database, we identified 818 MCP joint arthroplasties performed in 285 patients from 1998 to 2012, including 690 primary arthroplasties and 128 revision arthroplasties. Primary diagnoses included inflammatory arthritis (667), osteoarthritis (75), and posttraumatic arthritis (76). Periprosthetic fractures were identified through review of medical records., Results: Intraoperative periprosthetic fractures occurred in 23 (3%) fingers (21 patients), including 19 primary and 4 revision arthroplasties. Twelve fractures required stabilization, 4 required only bone grafting, and 1 required both. The fractures occurred during broaching (12), implantation (10), or prior implant removal (1). Diabetes mellitus (DM), younger age, pyrocarbon implant insertion, and cementless fixation increased risk for intraoperative fracture. In particular, DM and the use of pyrocarbon implants significantly increased fracture risk. At 4 years (range, 1.3-10.2 y) average follow-up, no patient with intraoperative fracture had developed a subsequent fracture compared with 3 postoperative fractures in patients without intraoperative fractures. All fractures had healed by the time of the last follow-up. The 2- and 5-year implant survival rates were 96% and 80% in those with intraoperative fractures, respectively, which was not significantly different from those without an intraoperative fracture. When comparing patients with an intraoperative fracture with those without, there was an increased risk of postoperative MCP joint instability defined as implant dislocation. Patients with intraoperative fractures still had noteworthy improvements in their postoperative pain levels and pinch strengths., Conclusions: Intraoperative fractures occurred in 3% of MCP joint arthroplasties, including 3% of primary and 3% of revision arthroplasties. Increased risk for fracture was associated with the use of pyrocarbon implants, cementless fixation, and DM. Although these fractures did not appear to adversely affect implant survival, they were associated with increased risk of postoperative instability., Type of Study/level of Evidence: Prognostic III., (Copyright © 2015 American Society for Surgery of the Hand.

Arthritis of the metacarpophalangeal joint can result in considerable disability and pain. Inflammatory, posttraumatic, crystalline, and osteoarthritis are common etiologies of joint disease. A variety of nonsurgical treatment options have been shown to be effective, including activity modification, anti-inflammatory medications, splinting, and cortisone injections. In addition, newer generation disease-modifying antirheumatic drugs geared toward the treatment of rheumatoid arthritis have shown promise in retarding the inflammatory process. Another, relatively newer, conservative treatment option includes topical anti-inflammatories such as diclofenac sodium that are now approved by the Federal Drug Administration. Surgical treatment options most commonly include arthroplasty and arthrodesis. In the treatment of thumb metacarpophalangeal arthritis, arthrodesis is a popular and generally reliable surgical solution. In the fingers, arthroplasty remains the most common treatment option. Traditional constrained silicone joint replacements remain the most commonly used. Newer generation, unconstrained, surface replacement arthroplasties have shown promise in the treatment of osteoarthritis and select cases of inflammatory arthritis in which there is good bone stock, no or minimal deformity, adequate supporting soft tissues, and good disease control., (Copyright © 2011.

Purpose: Pyrolytic carbon implants have been successfully used in the treatment of osteoarthritis of the metacarpophalangeal and proximal interphalangeal joints. Recently, pyrolytic carbon hemiarthroplasties have been proposed for the treatment of osteoarthritis of the trapezial-metacarpal (TM) joint of the thumb. We wished to review our short-term outcomes for this device in the treatment of TM arthritis., Methods: Fifty-four arthritic TM joints in 49 patients, with a mean age of 59 years, were treated with use of a pyrolytic carbon hemiarthroplasty procedure. Underlying diagnoses included osteoarthritis in 44 thumbs, rheumatoid arthritis in 8 thumbs, psoriatic arthritis in 1 thumb, and juvenile rheumatoid arthritis in 1 thumb. The patients were followed up clinically as well as radiologically for an average of 22 months postoperatively., Results: The overall 22-month survival rate excluding scaphotrapezio-trapezoidal joint arthritis was 80% according to a Kaplan-Meier analysis. Ten metacarpal subluxations were observed. Seven of these cases were salvaged by increasing the depth of the trapezial cup. A total of 15 reoperations were required in this cohort. No complications were seen in the patients with inflammatory arthritis. Thirty-five patients were pain free at the latest follow-up, and 6 reported mild to occasional pain with repetitive activities. The overall satisfaction rate was 40 of 49 patients (81%). Grip strength recovered to 86% of that of the contralateral side. Apposition key and opposition pinch strength improved to 92% and 95%, respectively, of those of the contralateral hand., Conclusions: Pyrolytic carbon thumb arthroplasty may prove to be an acceptable option for the treatment of TM, although a high complication rate was observed in this early cohort, with many cases of subluxation attributed to the creation of a too shallow trapezial cup. Further comparative studies are warranted., Type of Study/level of Evidence: Therapeutic IV.

Purpose: Reported outcomes of trapeziometacarpal (TM) arthrodesis have been contradictory. The purpose of this paper is to review the long-term results of TM arthrodesis for arthritis with respect to clinical outcomes, union, development of adjacent joint arthritis, and complications., Methods: A retrospective review of TM arthrodeses performed between 1970 and 2003 was undertaken. Among a total of 241 arthrodeses performed, 126 thumbs in 114 patients (79 women, 35 men) treated for osteoarthritis were available for follow-up evaluation. Pre- and postoperative clinical and radiographic data were reviewed. The average age was 57 years (range 32-77). The dominant hand was involved in 76 cases. Supplemental bone graft was used in 90 thumbs. Preoperative appositional (key) pinch, oppositional (tip) pinch, and grip strengths were 3.0 kg, 2.7 kg, and 14 kg, respectively. The average pain score on a scale of 0-10 was 6.6 (range 4-10). The average follow-up was 11.2 years (range 3-28 years)., Results: There were 17 nonunions. No correlation existed between the incidence of nonunion and the use of supplemental bone graft. Nine of 17 thumbs had re-operation, including revision arthrodesis (6) and interposition or suspensionplasty (3). The appositional pinch, oppositional pinch, and grip strengths improved to 5.9 kg, 5.4 kg, and 23 kg, respectively (p < .01). The average pain score improved to 0.4 (p < .01). Radiographic progression of scaphotrapeziotrapezoid arthritis occurred in 39 cases; however, only 8 of these were symptomatic. Development of metacarpophalangeal arthritis was noted in 16 thumbs; none have been clinically relevant., Conclusions: For most patients TM arthrodesis reduces pain, improves function and results in excellent patient satisfaction. Despite the development of metacarpophalangeal and scaphotrapeziotrapezoid joint arthritis, intervention for these joints was rarely warranted., Type of Study/level of Evidence: Therapeutic IV.

Purpose: To review early outcomes of arthritic metacarpophalangeal (MCP) joints treated with nonconstrained pyrolytic carbon implants to evaluate efficacy, clinical outcomes, and durability., Methods: One hundred forty-two consecutive arthroplasties (61 patients) were retrospectively reviewed. Diagnoses included osteoarthritis (OA), traumatic arthritis, and inflammatory arthritis. One hundred thirty were primary joint replacements, and 12 were prior-silicone revisions. The average patient age was 55 years (range, 21-77 years); 36 patients were women and 25 were men. Average follow-up period was 17 months (range, 3-42 months), and 43 patients were followed up for a minimum of 1 year., Results: For OA patients, according to the analog pain scale used, pain decreased from 73.0 to 8.5 of 100, functionality increased from 20.1 to 86.6 of 100, and appearance improved from 62.7 to 93.6 of 100. The rheumatoid arthritis (RA) group showed decreased pain from 43.1 to 8.9 of 100, functional improvement from 26.7 to 83.3 of 100, and increased appearance from 25.2 to 77.1 of 100. At 1 year, satisfaction was greater than 90% for both groups. Arc of motion for OA patients improved from 44 degrees to 58 degrees . Oppositional pinch increased 126%, and grip strength improved 40%. Rheumatoid arthritis patients increased their MCP joint motion arc from 32 degrees to 45 degrees . Oppositional pinch increased 89%, but grip strength decreased. Radiographs at 1 year demonstrated stable prostheses in all of the OA joints. The RA group overall demonstrated evidence of axial subsidence (10.5% of joints) and periprosthetic erosions (16.4% of joints). In RA joints with greater than 1-year follow-up period, 55.0% had axial subsidence, 95.0% had an increased radiolucent seam, and 45.0% had periprosthetic erosions. The overall implant survivorship is 141 joints to date. The overall minor complication rate was 6%, and major complication rate was 9%., Conclusions: Preliminary results suggest that pyrolytic carbon MCP joint arthroplasty provides good pain relief, patient satisfaction, and functional improvement in managing OA and select cases of RA. Longer follow-up evaluation will help validate these promising early results., Type of Study/level of Evidence: Therapeutic IV.

Unconstrained pyrolytic surface replacement arthroplasty provides the benefits of a more natural center of rotation with preservation of native ligamentous joint stability. Initial short-term results show excellent motion, pain relief, and restoration of pinch and grip strength. These results are encouraging, and suggest that pyrolytic carbon arthroplasty may be a reasonable option for joint salvage in patients suffering from MP joint osteoarthritis.

Purpose: A septic joint is a cartilage-threatening emergency requiring prompt treatment. The purpose of this study was to examine outcomes of septic arthritis of the metacarpophalangeal and interphalangeal joints. Methods: We performed a retrospective review of patients diagnosed with joint infection between 1976 and 2008. The end point included the number of arthrodeses and amputations performed. Results: Septic joints were identified in 110 patients. All patients had incision and irrigation and debridement (I and D) of the joint. The infection was successfully treated in 83 of 110 patients. The majority of septic joints (73 of 83 patients) treated successfully with I and D had only a penetrating joint injury. Forty-eight of these patients required more than one I and D to eradicate the infection. The remaining 27 of 110 patients required either arthrodesis (13 patients) or amputation (14 patients) despite I and D. Among the 13 patients requiring arthrodesis, postoperative infection (7 patients) accounted for the majority of septic joints. Of the 14 patients requiring amputation, penetrating joint injury accounted for the majority of septic joints. Overall, those patients requiring more than 3 I and D procedures were at higher risk of arthrodesis or amputation. Increasing comorbidities correlated with worsening outcomes. Conclusions: Pyarthrosis can often be treated successfully with 1 or more I and D procedures. Despite multiple I and D procedures, 27 patients required either arthrodesis or amputation. The time to diagnosis and treatment, the number of I and D procedures, patient comorbidities, and postoperative infection following non-joint surgery are major factors influencing outcome. Type of study/level of evidence: Prognostic III. [ABSTRACT FROM AUTHOR]

Purpose: To determine the cumulative prevalence of septic arthritis presenting to the emergency department of an academic medical center and evaluate the use of clinical data to diagnose infection versus inflammation. Methods: We conducted a records review of a single institution with 80,000 annual emergency room visits. We included a consecutive series of patients with suspected wrist infection from January 1, 2007, to December 31, 2008. Adults complaining of atraumatic wrist pain with either erythema or swelling on physical examination or a final diagnosis of septic arthritis, gout, pseudogout, cellulitis, wrist hematoma/edema, or wrist arthritic flare were suspected to have infection. We collected data using a standardized data abstraction form. Results: We reviewed 804 patient records. A total of 104 patients meeting inclusion criteria for suspected wrist joint infection during the 2-year study period were included. Mean age was 62.5 years (SD, 20.2 y); 63 were men. There were 12 patients with a history of gout, 4 with a history of pseudogout, and 19 with a history of diabetes. Wrist arthrocentesis was performed in 31 patients, and 11 underwent surgical treatment. There were 16 patients with a final diagnosis of gout, 11 with pseudogout, 43 with cellulitis, 13 with upper extremity hematoma/edema, and 15 with wrist arthritic flare. The cumulative prevalence of septic arthritis was 5%. Conclusions: In this series of emergency department patients with suspected wrist joint infection, gout, pseudogout, and cellulitis were the most common etiologies. The cumulative incidence of septic wrist arthritis was low. [ABSTRACT FROM AUTHOR]

Purpose: To retrospectively review the surgical technique, postoperative therapy/splinting protocols, and clinical and radiographic outcomes of patients who had pyrolytic carbon proximal interphalangeal (PIP) joint arthroplasty. Methods: A total of 50 PIP joint replacements in 35 patients were performed with a minimum follow-up period of 27 months. Indications for surgery included pain, decreased range of motion, instability, and/or deformity. The preoperative diagnosis was osteoarthritis in 14, rheumatoid arthritis in 11, and posttraumatic arthritis in 10. There were 20 women and 15 men affected. The average age at the time of surgery was 53 years. The fingers replaced included the index (15), middle (18), ring (10), and small (7). The preoperative arc of motion averaged 40° (0°–60°), and the pinch and grip measurements averaged 3 and 19 kg, respectively. The preoperative pain scores averaged 6 (scale, of 0–10) on a visual analog space scale. Results: The arc of motion was 47° after surgery, and the average pinch and grip measurements were 4 and 25 kg, respectively. Pain scores improved to 1. At the final follow-up evaluation the overall patient satisfaction was nearly 80%. The results of index finger PIP replacements are compatible with other digits. Fourteen joints (in 14 patients) to date have required additional procedures to improve or maintain joint motion/function or pain; 5 for minor reasons and 9 for major complications. The revision arthroplasty rate was 8%. No infections were noted. Although not medically necessary, 2 patients requested and had an amputation. Radiographic subsidence and subsequent settling (in accordance with Wolff’s law) without apparent loosening occurred in 20 joints. Conclusions: Our 2-year minimum follow-up evaluation of pyrolytic carbon implant arthroplasty showed improved pain relief and good overall patient satisfaction. Twenty-eight percent of patients required a second procedure and 8% required a revision arthroplasty. Radiographs showed gross changes in implant and eventual settling to a stable position in 40% of the joints. A longer follow-up period will help to better determine the efficacy of this implant. Type of study/level of evidence: Therapeutic, Level IV. [Copyright &y& Elsevier]
