Background/Objectives: Trapeziometacarpal (TM) joint involvement is common in inflammatory rheumatic disease and may result in pain, instability, and functional impairment. Although TM arthroplasty is widely performed for primary osteoarthritis, evidence in patients with inflammatory arthropathy remains limited. This multicenter study evaluated clinical outcomes, complications, and revision rates of TM arthroplasty in patients with inflammatory rheumatic disease. Methods: We conducted a retrospective multicenter cohort study including patients with inflammatory rheumatic disease who underwent primary TM arthroplasty at tertiary referral centers. Demographic, clinical, radiographic, and surgical data were collected. Standard radiographs obtained at 1, 6, and 12 months postoperatively were reviewed to assess implant stability, radiolucent lines, and implant-related complications. Primary outcomes included revision rate and complications; secondary outcomes included functional recovery. Results: Fourteen patients undergoing 15 TM arthroplasties were included; one patient underwent bilateral surgery. The cohort was predominantly female (64%), with a mean age of 63 years. Mean clinical follow-up was 12.8 months (range, 12–18). Functional outcomes improved significantly following surgery, with substantial reductions in QuickDASH disability scores. One complication (1/15 procedures; 6.7%) occurred, consisting of a postoperative hematoma managed nonoperatively. No revision surgeries were required among 15 procedures during the available follow-up, corresponding to a revision rate of 0%. Conclusions: TM arthroplasty in inflammatory rheumatic disease was associated with satisfactory functional outcomes, a low complication rate, and no revision procedures during short-term follow-up, suggesting that TM arthroplasty may represent a potential option in carefully selected patients.

Background: Total trapeziometacarpal (TMC) joint arthroplasty has emerged as a surgical option for selected patients with TMC osteoarthritis. The HORUS^® prosthesis (Evolutis, France) is a novel uncemented modular implant featuring a threaded screw-in trapezial cup coated with porous titanium and a PEXEL-E liner (vitamin E-infused cross-linked polyethylene) with a semi-retentive articulation. The purpose of this study was to report preliminary clinical and radiographic outcomes of total TMC joint arthroplasty using the uncemented HORUS^® prosthesis at 6-month follow-up. Methods: Eleven patients (8 women, 3 men; mean age 63.6 ± 10.1 years) with Eaton-Littler stage II–III TMC osteoarthritis and at least 6 months of unsuccessful conservative treatment underwent total TMC joint arthroplasty using the HORUS^® prosthesis. All procedures were performed by a single surgeon through a dorso-radial approach. Clinical outcomes were assessed preoperatively and at 15 days, 1, 3, and 6 months postoperatively using the Visual Analogue Scale (VAS), QuickDASH questionnaire, and Kapandji opposition score. Standardized radiographs were assessed at 1, 3, and 6 months for component position, periprosthetic radiolucency, cup migration/loosening, and stem subsidence. Results: One intraoperative trapezial fracture (1/11; 9.1%) required conversion to trapeziectomy with suspension arthroplasty; this patient was excluded from the prosthetic outcome analysis. In the remaining 10 patients, mean VAS decreased from 8.7 ± 1.1 preoperatively to 0.3 ± 0.7 at 6 months, mean QuickDASH decreased from 66.2 ± 11.3 to 14.5 ± 7.6, and mean Kapandji score increased from 5.8 ± 0.8 to 9.2 ± 0.6. One minor postoperative complication occurred (flexor tendinopathy of the third and fourth digits at 4 weeks). No dislocation, infection, or radiographic evidence of component migration, stem subsidence, or periprosthetic radiolucency was detected during the 6-month observation period. Conclusions: In this small preliminary series, the HORUS^® prosthesis was associated with marked short-term improvements in pain, disability, and thumb opposition. These data should not be interpreted as evidence of long-term implant survival or a reduced risk of loosening because the cohort was small and follow-up was limited to 6 months. Larger comparative studies with longer follow-up are required to assess durability, implant-related complications, and revision risk. Full article

Background: Trapeziometacarpal (TM) osteoarthritis (OA) is a common condition, especially among postmenopausal women, often requiring surgical intervention when conservative treatment fails. In recent years, dual-mobility prostheses have been increasingly used as an alternative to traditional trapeziectomy with suspension arthroplasty. However, limited data exist regarding their comparative cost-effectiveness in public healthcare systems. Purpose: The aim of this study was to compare the cost–benefit ratio and clinical outcomes of two surgical techniques for TM OA: trapeziectomy with suspension arthroplasty and total joint arthroplasty with a dual-mobility prosthesis. Methods: We conducted a retrospective cohort study of 116 hands treated between 2020 and 2024. Patients were divided into two groups based on the surgery they received: trapeziectomy with suspension arthroplasty or implantation of a dual-mobility TM prosthesis. Clinical outcomes were assessed using VAS, DASH, Kapandji score, grip strength, and pinch strength at 12, 36, and 48 months postoperatively. A cost analysis was performed based on hospital reimbursement (Diagnosis-Related Group) and estimated productivity loss. Results: Both techniques yielded significant improvements in pain and function. Patients who were operated on with a prosthesis showed faster recovery and better early outcomes, while the trapeziectomy group had lower direct surgical costs and fewer complications. At 48 months, clinical scores were comparable. The overall cost–benefit ratio favoured trapeziectomy with suspension arthroplasty, while TM prosthesis’s higher costs were justified due to improved short-term functional recovery. Conclusions: Both surgical techniques achieved satisfactory long-term clinical outcomes. The prosthetic option allows for quicker recovery and reduces indirect social costs, while suspension arthroplasty remains more cost-effective for direct costs. These findings highlight the importance of balancing clinical benefit and economic sustainability in surgical decision-making for TM osteoarthritis. Level of Evidence: Level III, retrospective comparative study. Full article

Background: Thumb carpometacarpal (CMC) arthritis affects up to 25% of women and 8% of men over 70 years of age, significantly compromising their activities of daily living. With the rapid growth of the elderly population globally and their specific clinical needs, understanding optimal surgical treatment for this age group is crucial. This systematic review compares trapeziectomy with ligament reconstruction and tendon interposition (LRTI) versus dual-mobility prosthesis for treating thumb CMC arthritis in elderly patients over 70 years old. Methods: A systematic search was conducted across PubMed, Scopus, Web of Science, and the Cochrane Library for studies published up to August 2025. Studies that directly compared both techniques were included, with subgroup analyses performed for elderly patients over 70 years of age when data were available. Primary outcomes included pain relief, functional improvement, grip and pinch strength, complications, and patient satisfaction. Results: Five studies met the inclusion criteria for direct comparison of both techniques, encompassing 313 patients (324 thumbs). While none exclusively focused on patients over 70, elderly patients represented 25–41% of study populations. Due to the absence of age-stratified data in the original studies, our analysis encompasses all age groups with specific considerations for elderly patients where identifiable. Dual-mobility prostheses demonstrated faster pain relief and earlier functional improvement, particularly within the first 3–6 months postoperatively. Prostheses consistently provided superior grip and pinch strength outcomes throughout follow-up periods. Both procedures effectively preserved thumb function, but prostheses better maintained thumb length and metacarpophalangeal stability. While complication rates were comparable, LRTI complications were typically minor and self-limiting, whereas prosthesis complications, though rare, could potentially require revision surgery. Longer-term follow-up data (>3 years) remain limited, particularly regarding implant degradation and adverse local tissue reactions. Conclusions: Both procedures effectively treat thumb CMC arthritis in elderly patients, with distinct advantages. Dual-mobility prostheses offer faster recovery, enhanced strength, and better thumb length preservation, making them potentially advantageous for elderly patients prioritizing rapid functional recovery. Trapeziectomy with LRTI provides reliable long-term pain relief with fewer serious complications, making it suitable for patients with poor bone quality or significant comorbidities. Treatment selection should be individualized based on patient characteristics, functional demands, and surgeon expertise. Future research specifically focusing on elderly populations with longer follow-up periods (>5 years) is critically needed to provide stronger evidence for this growing demographic and to better understand long-term implant performance.

Background: Carpometacarpal (CMC-I) arthritis is a frequent and disabling condition. Standard surgical options include trapeziectomy and prosthetic arthroplasty. While quantitative outcomes have been widely studied, little is known about patient perspectives regarding function, aesthetics, and rehabilitation. Methods: We conducted semi-structured interviews with ten patients who had undergone trapeziectomy on one side and prosthesis implantation on the contralateral side. Interviews were performed ≥6 months postoperatively, audio-recorded, transcribed verbatim, and analyzed thematically following Braun and Clarke’s framework. Researcher triangulation and member checking were applied to enhance trustworthiness. Results: Four overarching themes were identified. (1) Strength: Most patients reported greater strength and endurance on the prosthetic side, though both hands were generally adequate for daily activities. (2) Rehabilitation: Recovery after prosthesis implantation was described as markedly faster and less burdensome, with reduced need for therapy compared to trapeziectomy. (3) Aesthetics: Trapeziectomy was often associated with dissatisfaction due to thumb shortening and collapse, while prostheses were perceived as restoring a more natural appearance. (4) Surgical preference: When asked which procedure they would hypothetically choose again, all participants favored prosthesis implantation, citing superior function, faster recovery, and more favorable aesthetics. Conclusions: Patients who experienced both procedures consistently preferred prosthesis implantation. Their narratives highlight dimensions beyond standard clinical scores, including rehabilitation burden, appearance, and psychosocial impact. Incorporating patient-reported outcomes into surgical counseling is essential to align treatment of CMC-I arthritis with patient priorities and to support shared decision-making. Full article

Background: Carpometacarpal thumb arthritis causes pain and functional limitations. Methods: This study evaluated the efficacy of arthroscopic partial trapeziectomy with free palmar longus tendon suspension and interpositional arthroplasty, combined with a soft anchor internal brace, for the treatment of thumb basal joint arthritis. Between August 2010 and April 2020, 60 thumbs with symptomatic basal joint arthritis (Eaton stage II–III) were treated using this minimally invasive technique. Results: The cohort included 52 female and 8 male patients (mean age, 62.6 ± 4.3 years), who underwent clinical follow-up for 28.7 ± 3.0 months. VAS pain scores decreased from 5.7 ± 0.5 to 1.0 ± 0.7 and 7.1 ± 0.6 to 1.4 ± 0.9 (p < 0.001) during rest and activity, respectively. Thumb range of motion increased from 43.3 ± 11.3 to 54.2 ± 9.8 degrees, while pinch strength improved from 47.3 ± 9.5% to 88.8 ± 17.3% of the contralateral side (p < 0.001). Patients with Eaton stage II disease demonstrated better outcomes than those with stage III disease. Radiographically, minimal proximal migration of the first metacarpal (mean, 1.2 mm) was observed, with no cases of scaphotrapezial joint arthritis. Conclusions: Arthroscopic partial trapeziectomy with tendon suspension/interposition and an internal brace is an effective treatment for Eaton stage II–III basal joint arthritis, offering significant pain relief, functional improvement, and joint stability, while preserving the scaphotrapezial joint.

Background: For many years, advancements in hand joint replacement (JR) were relatively minor compared to those for large joints. However, the caution previously exercised due to high complication rates is gradually being replaced by the expanding use of JR therapies for small joints in the hand. Despite this progress, there is a lack of comprehensive data on the outcomes of hand JR and on the optimal infrastructure required to meet the growing demand for these therapies. Methods: This study examined trends and revision rates of JR for thumb carpometacarpal (CMC-1) and finger (MCP and PIP) joints in both inpatient and outpatient settings in Germany. Data from the Federal Statistical Office of Germany (Destatis) and the Central Institute for Statutory Health Insurance Physicians (ZI) were analyzed, focusing on the incidence, demographics, and outcomes of these procedures. Results: This study found a substantial national increase in prosthetic treatments specifically for CMC-1, with a 2.18-fold rise in the outpatient sector compared to a 1.65-fold increase in inpatient treatments. Despite this shift, 83.7% of JR procedures were still performed in an inpatient setting. Conclusions: The overall complication rates appear to be declining, suggesting that while the management of these procedures is shifting towards outpatient care, the quality remains stable.

Thumb carpometacarpal arthroplasty has become a widely used standard technique in the surgical treatment of thumb carpometacarpal osteoarthritis. One of the most critical steps during this procedure is proper surgical exposure of the trapezium and the base of the first metacarpal to allow for prosthesis implantation. This article introduces a surgical technique in which a roll constructed from gauze sponges tightly wrapped with medical tape facilitates several steps in thumb carpometacarpal arthroplasty. While performing a dorsoradial approach to the thumb carpometacarpal joint, this cost-effective tool is perfectly tailored to the joint’s unique anatomy. It aids in precise hand positioning and ensures optimal exposure of the trapezium and base of the first metacarpal, which is crucial for accurate cup and stem preparation as well as for unimpeded prosthesis implantation.

Joint replacement arthroplasty for the treatment of thumb osteoarthritis is gaining popularity as recent studies have demonstrated better pinch and grip strength and faster rehabilitation. Our aim was to identify early complications in modern implant designs using a multicenter study. A total of 381 patients who underwent thumb carpometacarpal replacement surgery in six participating hospitals were enrolled. The complications included were fractures, dislocations, infections, tendon and nerve injuries, and complex regional pain syndrome. Major complications were defined as a failure to implant the prosthesis, revision surgery to remove the implant, and any other need for further surgical intervention. The secondary outcomes were any other complications treated non-surgically and the timing of the complications. Eleven procedures failed, and these patients were treated with trapeziectomies. Twelve other patients required repeat surgical interventions. Minor adverse events occurred in 25.4% of the cases, and transient irritation of the superficial radial nerve and De Quervain tendinopathy were the most prevalent complications. Although this cohort depicted the learning curves of multiple surgeons, our study demonstrated low short-term failure rates. An inability to achieve primary stability of the cup in the trapezium was the leading cause of failure. Dislocations and other major complications with modern implants were very few. Full article

Liparthroplasty has recently been discussed as a promising bridging therapy after failed conservative treatment options to postpone arthroplasty surgery of the thumb carpometacarpal joint as long as possible. The current study investigates the sustainability of this method in seven stage II and twenty-four stage III osteoarthritis patients (twenty-seven female and four male cases). Data were evaluated preinterventionally, six months postinterventionally, and two years postinterventionally, as well as a final follow-up assessment after median 5.1 years. We found a significant reduction of all postinterventional disabilities of the arm, shoulder, and hand (dash) scores and pain levels compared to the ones prior to liparthroplasty. Moreover, we even detected a reduction in both parameters within the postinterventional course, so that the DASH scores of our final investigation were significantly lower than the values after six months. Furthermore, 12 of our 31 cases demanded a surgical conversion due to recurrence of symptoms. A binary regression analysis found smokers to have 11 times higher odds for therapy failure, leading to surgical conversion. Seventeen out of nineteen patients in our final assessment stated that they were pleased with liparthroplasty. Due to favorable mid-term outcomes of 61% of the 31 initially treated patients, we recommend liparthroplasty as a reliable bridging therapy for preserving joint integrity as long as possible, especially in non-smoking patients.

Pollux adductus deformity is an accompanying symptom of thumb carpometacarpal osteoarthritis. We describe a case of a patient who presented with increased muscle tone of the adductor pollicis muscle and chronic pain in the thenar musculature, i.e., recurrence of an adduction deformity. The patient reported a symptom-free period of 5.5 years after having received resection-suspension-arthroplasty for stage IV thumb carpometacarpal osteoarthritis until spasmodic pain appeared. Due to the functional impairment of this condition, we administered therapy including 100 units of Botox^® (onabotulinumtoxinA, Allergan, Dublin, Ireland) injected with a fanning technique into the adductor pollicis muscle. Thus, we observed a substantial improvement in the patient-reported outcome measures as well as pain levels compared with initial values. The current case shows the pivotal role of the adductor pollicis muscle when patients report pain at the base of the thumb, which can cause considerable impairments despite the complication-free surgical treatment of thumb CMC OA.

The dual mobility concept currently represents the newest generation of thumb carpometacarpal prostheses. The aim of this study was to evaluate the short-term outcomes of TOUCH^® prosthesis. From September 2019 to July 2020, 40 prosthesis were implanted in 37 patients suffering from symptomatic stage III osteoarthritis. All included patients with a median age of 57.7 (IQR: 13.6) finished the systematic follow-up regimen (4, 8, 16 weeks, 6, and 12 months postoperatively). All parameters significantly improved (p < 0.0001) compared to the preoperative status. At 1 year follow-up, median DASH Scores decreased from 54 (IQR 22) to 12 (IQR 28) and pain levels improved from 8 (IQR 2) to 1 (IQR 2). Moreover, key-pinch strength increased from 3.8 (2.0) to 5.8 (2.5), while palmar abduction, radial abduction, and opposition also significantly improved. 35/37 patients were satisfied with the functional outcomes. We observed 10 complications, of which 6 were tendon-related issues, and 2 were due to an inappropriate choice of neck size. We could detect one dislocation but no evidence of cup loosening, tilting or subsidence in any patient. Despite the occurrence of some complications, we recommend implantation of this prosthesis type due to favorable clinical and radiological performance. Full article

Adipose-derived mesenchymal stem cell (ASC) therapy is currently a focus of regenerative medicine. Lipoaspirate is rich in ASCs and is evolving into a promising, less-invasive tool to treat thumb carpometacarpal osteoarthritis as compared with common surgical techniques, for example, trapeziectomy or prosthesis implantation. The present study aimed to examine the effect of 1 mL intraarticular lipoaspirate injection (liparthroplasty) in 31 thumb carpometacarpal osteoarthritis patients (27 woman and four men) with a median age of 58 (interquartile range (IQR) of 10) years and Eaton–Littler Stage 2 or 3. Median pain levels assessed via visual analogue scale significantly decreased from 7 (IQR 2) to 4 (IQR 6) after six months (p < 0.0001) and 2 (IQR 5) after two years (p < 0.0001). Median pre-interventional Disabilities of the Arm, Shoulder and Hand (DASH) scores of 59 (IQR 26) significantly reduced to a value of 40 (IQR 43) after six months (p = 0.004) and to 35 (IQR 34) after two years (p < 0.0001). Subjective grip strength showed no significant improvement. However, the time until recurrence of symptoms was measured and a cumulative remission rate of 58% was detected after two years. Satisfaction rates were 68% after six months and 51% after two years. In conclusion, liparthroplasty represents a promising option to reduce pain and functional impairment and to postpone surgery for a certain period of time. Full article
