Trapeziometacarpal Prostheses Research Articles

Long-term results of 292 CarpoFit®-joint replacements for trapeziometacarpal osteoarthritis: a prospective cohort study with a 10-year follow-up.

We report a prospective consecutive series of CarpoFit® (Implantcast, Buxtehude, Germany) trapeziometacarpal prostheses used between 2006 and 2014 for 292 patients with stage I-III trapeziometacarpal arthritis who remained symptomatic after conservative treatment. Patients were assessed at 3 months, 6 months and 1 year postoperatively for thumb movement, pinch strength and by validated patient-derived outcome scores and radiographs. Follow-up at 5 and 10 years was by outcome scores alone. Complications and revisions were recorded. Of the patients, 91% were either satisfied or very satisfied with their treatment at 10 years. Pain relief and functional outcomes were significantly improved within 3 months. Results were sustained during the entire observation period. The implant survival was 95% after 10 years. Prosthetic arthroplasty is a reliable treatment option for trapeziometacarpal osteoarthritis and the CarpoFit® prosthesis has excellent long-term results for patient satisfaction, functional scores and implant survivorship.Level of evidence: III.

Metal hypersensitivity in trapeziometacarpal arthroplasty: A systematic pattern of progression

Metal hypersensitivity is a rare and often underestimated complication, as shown by the small number of published studies, particularly concerning the upper limbs and the hand. However, the increase in the annual number of trapeziometacarpal arthroplasties underlines the importance of better understanding of this problem.We performed a study based on data from the revision of trapeziometacarpal prostheses to assess the incidence of this complication and to define a sequence of radiological changes to detect metal hypersensitivity.This single-center retrospective study included 37 patients operated on between January 2014 and November 2023 for revision of trapeziometacarpal prosthesis. Ten (27%) had no clearly identified cause of failure.For these 10 patients, we analyzed clinical data and postoperative X-rays. In the 11 revision arthroplasties, 2 patients had no symptoms or radiographic signs suggestive of allergy. Six patients had a-posteriori diagnosis established by allergy testing, which also identified 2 additional patients, for a total of 8 patients (21% of the initial cohort). In these cases, there was systematic metaphyseal osteolysis of the first metacarpal between 15 days and 1 month after implantation. Clinically, most patients had an asymptomatic period of 2 weeks to 1 month before onset of symptoms and osteolysis, often accompanied by local inflammation.This study found a reproducible pattern of progression, characterized by the appearance of radiographic signs of osteolysis in the first month, followed by clinical deterioration. Although this course is strongly suggestive of a metal hypersensitivity, it is crucial not to exclude the possibility of an infectious cause, which should always be considered.

De Quervain’s tendinitis after trapeziometacarpal arthroplasty

ObjectivesDe Quervain’s tendinitis is frequently observed after placement of a trapeziometacarpal prosthesis. The aim of this study was to investigate the relationship between De Quervain’s tendinitis, osteoarthritis of the thumb and placement of a trapeziometacarpal prosthesis. The second aim was a critical analysis of the literature in search of a cause for this postoperative event after arthroplasty or trapeziectomy. MethodsWe reviewed a series of 331 trapeziometacarpal prostheses. ResultsThere were no differences in thumb column length, gender, type of neck (straight or angled), or surgical approach between patients who developed De Quervain’s tendinitis and those who did not. However, the frequency of De Quervain’s tendinitis was much higher after arthroplasty than trapeziectomy. ConclusionsWe believe that the preoperative frequency of De Quervain’s tendinitis in trapeziometacarpal osteoarthritis is underestimated, being part of a more general pain symptomatology. More precise and specific examination is needed for a better preoperative diagnosis.Trapeziometacarpal osteoarthritis should be considered within a more global framework of peri-trapeziometacarpal pathology, including the trapeziometacarpal and triscaphoid levels, the articular ligaments and the abductor pollicis longus, extensor pollicis brevis, flexor pollicis longus, and flexor carpi radialis tendons.

Proposed Radiographic Parameters to Optimize Clinical Outcomes in Trapezio-Metacarpal Prosthesis Placement Using CT Imaging, with 1-Year Follow-Up.

Addressing trapezio-metacarpal (TMC) osteoarthritis often involves considering TMC joint replacement. Utilizing TMC prostheses offers advantages such as preserving the thumb length and more accurately replicating the thumb's range of motion (ROM). TMC prostheses have an intrinsic risk of dislocation and aseptic loosening. Analyzing pre- and postoperative imaging can mitigate complications and improve prosthetic placement, providing insights into both successes and potential challenges, refining overall clinical outcomes. We conducted a prospective analysis of 30 patients with severe TMC arthritis treated with a Touch© (Kerimedical, Geneva, Switzerland) prosthesis in 2021-2023: X-ray and CT protocols were developed to analyze A) the correct prosthesis placement and B) its correlation with clinical outcomes (VAS, Kapandji and QuickDASH scores) by performing Spearman correlation analysis. The average differences in trapezium height and M1-M2 ratio pre- and post-surgery were, respectively, 1.8 mm (SD ± 1.7; p < 0.001) and 0.04 mm (SD ± 0.04; p = 0.017). Pre-to-postoperative M1 axis length increased by an average of 2.98 mm (SD ± 3.84; p = 0.017). Trapezial cup sinking, indicated by the trapezium index, measured 4.6 mm (SD ± 1.2). The metacarpal index averaged at 11.3 mm (SD ± 3.3). The distance between the centers of the trapezium distal surface and the prosthesis cup was 2.23 mm (SD ± 1.4). The Spearman correlation analysis gave the following results: negative correlations were highlighted between postoperative VAS scores and the M1/M2 ratio and residual trapezium height (correlation coefficient: -0.7, p = 0.03 and -0.064, p = 0.03, respectively) at 6 months; a negative correlation was found at the 3-month mark between QuickDASH and the trapezium residual height (correlation coefficient: -0.07, p = 0.01); and a positive correlation was found for the trapezium index at 1 month (correlation coefficient: 0.07, p = 0.03) and 3 months (p = 0.04) using the Kapandji score. Similarly, we found a positive correlation between the distance between the prosthesis and trapezium centers and QuickDASH score at 1 and 3 months (correlation coefficient: 0.066, p = 0.03; correlation coefficient: 0.07, p = 0.05, respectively) and a positive correlation between prosthesis axis and the residual first metacarpal angle with QuickDASH score at 3 months (correlation coefficient: 0.07, p = 0.02). Pre- and postoperative systematic imaging analysis should become a method for predicting complications and guiding recovery in TMC prosthesis: CT imaging could provide us with radiographical landmarks that are intrinsically linked to clinical outcomes. Further research is necessary to fuel a protocol for the correct intraoperative TMC prosthesis implantation.

[Translated article] Experience in major complications with total trapezometacarpal prostheses

IntroductionThe treatment of rhizarthrosis using trapeziometacarpal prostheses (TMP) is increasing. Complications may lead to loss of the implant and result in salvage surgery. Our aim was to assess major complications with the use of some TMP models and their rescue. Material and methodRetrospective study on TMP implanted between 2006 and 2021. Models studied: Arpe®, Elektra®, Ivory®, Maïa®, Isis® and Touch®. Demographic data were assessed, implant placement by radiographic study, technical data, complications, salvage surgeries and final survival. ResultsReview of 224 TMP, 45 Arpe® (95.5% survival, rate follow-up [R] 6–16 years), 5 Elektra® (80% survival, R 13–14), 14 Ivory® (92.8% survival, R 9–11), 7 Maïa® (100% survival, R 8–9), 115 Isis® (99.1% survival, R 1–8), 38 Touch® (100% survival, R 1–4). The medial angle of the dome with the proximal articular surface of the trapezium in the lateral plane, was: Arpe®: 8.85°, Elektra®: not assessable, Ivory®: 6.6°, Maïa®: 14.4°, Isis®: 3.8°, and Touch®: 5.95°. The Isis® was placed 100% with scopic guidance presenting a significantly lower angle respect to the medial angle of the dome with the proximal articular surface of the trapezium. As main complications, we observed 3.5% of dislocations and 4% of mobilisations, with the Elektra® being responsible for 47% of these. Nineteen salvage surgeries were performed, with 3% of the implants being lost. ConclusionsDislocation and mobilisation are the most observed complications, the Elektra® responsible for almost half of them. Correct placement and implant design appear to be crucial to avoid them in the short and long term.

Contribution to the study of stresses in the thumb column during key pinch grip

ObjectivesThe aim of this study was to calculate the stress acting on the trapeziometacarpal joint during an key pinch grip. MethodWe used profile X-rays of the thumb to measure the various bony and muscle lever arms. We assessed the angles of action of the muscular elements involved in the thumb column. Based on this data, we established a two-dimensional geometric model that enabled us to determine the forces at each joint level, as a function of stresses and muscular contributions. We were also able to calculate the participation of the different muscle groups in obtaining a balanced situation. ResultsOur results, as a function of the degree of flexion of the interphalangeal and metacarpophalangeal joints, show a multiplying factor of 2.9–3.19 in relation to the key pinch grip force. DiscussionPrevious studies modelling a key pinch grip are showed multiplying factors from 6 to 13 in relation to the key pinch grip force. They are not compatible with the characteristics of the polyethylene used for trapeziometacarpal prostheses, whereas numerous articles in the literature show survival rates that are more or less comparable to those of total hip prostheses. These studies required an excessive number of assumptions, which could lead to error. Our results are compatible with the results of trapeziometacarpal prosthesis and with those of a recent study measuring intra-articular trapeziometacarpal pressure in a cadaveric model. Our model allows us to test different configurations of the thumb spine depending on the degree of flexion of the interphalangeal and metacarpophalangeal joints.

New radiographic monitoring indices for total trapeziometacarpal prostheses

ObjectiveThe objective of this study is to propose and evaluate a method of monitoring implants via the calculation of a trapezial and metacarpal index from radiological measurements and to describe an initial patient analysis. MethodsThis retrospective study describes the trapezial index which reflects the trapezial bone stock not occupied by the trapezial cup, while the metacarpal index reflects the rate of metacarpal occupation by the prosthetic stem. Those indexes were used on a series of 20 patients with a Maïa™ prosthesis with a minimum follow-up of seven years.The indexes were measured immediately postoperatively and at the various annual check-ups.Four observers measured each index on two occasions, to obtain an inter- and intra-observer correlation coefficient. ResultsThe average intra-observer correlation coefficient for the trapezium index was 0.94, for the metacarpal index 0.98. The inter-observer correlation coefficient was 0.93 for the trapezium index, 0.94 for the metacarpal index on average. The post-hoc calculated power was 0.98 as the number of subjects required was not usable.The mean immediate postoperative trapezial index was 45.74%, compared with a value at longest follow-up of 41.74%, reflecting a highly significant loss of height of 8,74%. The mean immediate postoperative metacarpal index was 77.69% compared with a mean value at longest follow-up of 78.99% indicating a non-significant increase in the index of 1,67%. ConclusionProposed indexes had excellent inter- and intra-observer correlation, the metacarpal one is stable over time whereas the trapezial one reveals changes in some patients, requiring further investigations.These simple and reproducible indexes allow precise monitoring of trapeziometacarpal prostheses and identify radiographic changes that should lead to additional examinations to improve survival of implants. Level of evidence: III, retrospective single cohort study.

Long-term survival analysis of 191 MAÏA® prostheses for trapeziometacarpal arthritis.

Surgery for trapeziometacarpal osteoarthritis after failure of medical treatment remains controversial. The aim of this study was to determine the long-term results of the MAÏA® trapeziometacarpal prosthesis (Lépine, Genay, France). This was a retrospective clinical and radiographic study of 191 MAÏA® trapeziometacarpal prostheses implanted between 2001 and 2016 from a single centre. The survival rate of the implants at the final follow-up of 12 years (range 17 days to 140 months) was 88%. Median pain score was 1/10. The median Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score was 20. The rate of major complications was 9% (5% dislocations and 4% loosening) with all dislocations needing revision surgery. The risk of prosthetic dislocation was highest during the first 3 years, most often related to malposition of the trapezium implant. The MAÏA trapeziometacarpal prosthesis represents a long-term solution for surgical treatment of thumb rhizarthrosis. Level of evidence: IV.

The concept of first metacarpal M1-M2 arch. New interest in trapeziometacarpal prostheses

Analysis of the M1-M2 arch, otherwise known as the M1-M2 metacarpal hanger, objectively helps all surgeons treating basal thumb osteoarthritis to fit a trapeziometacarpal prosthesis that respects the physiological length of the thumb column and thus the physiological tensions of the APL, EPL, and EPB tendons as well as the interossei and thenar muscles. Kapandji X-ray views are a gold-standard in the radiological study of basal thumb osteoarthritis, to classify progression, measure trapezium height, and assess the deformity. Ledoux’s M1/M2 ratio is the only method for assessing the normal length of the thumb column but cannot be easily used during surgery. We describe the first metacarpal arch, obtained by a radiological anteroposterior X-ray of the hand and wrist with the thumb in 45° abduction. It may be broken or conserved, depending on the form of osteoarthritis. It can objectively predict whether a prosthesis must be placed iso-long or so as to lengthen the thumb column. This overcomes the subjectivity of the notion of “intraoperative piston” and avoids excessive tensioning of the prosthesis, which would increase stress on the prosthetic components and thus the risk of wear and complications. We applied this technical principle to 148 dual mobility prostheses fitted between January 2019 and May 2021. By respecting the arch, the right trade-off is found between intraoperative stability and mobility while protecting the long-term performance of the prosthesis.

Erfahrungen mit Endoprothetik am Daumensattelgelenk

The complex kinematics of the saddle joint has been achallenge in the development of trapeziometacarpal prostheses. The introduction of the dual-mobility design increases the range of motion and limits strains on the cup fixation. Therefore, rates of loosening and dislocation have been markedly reduced. Furthermore, several studies showed asimilar relief of pain, range of movement and grip strength compared to the results of resection arthroplasty. The preservation of the length of the first ray as well as the more stable and functional joint can be favourable in younger and active patients. Further investigation is needed to determine whether or not those higher demands affect long-term survivorship. The high grade of patient satisfaction, the shorter recovery time and the safe surgical technique motivates considering the implantation of atotal endoprosthesis with adual-mobility cup as an attractive alternative to resection arthroplasty in the operative treatment for trapeziometacarpal osteoarthritis.

Initial survival of the Isis® total trapeziometacarpal prosthesis with conical trunk threaded cups

IntroductionThe treatment of trapeziometacarpal osteoarthritis through the implantation of total trapeziometacarpal prostheses is in continuous expansion. The Isis® prosthesis is a trunk-conical threaded anchorage prosthesis. Our objective was to assess the functional results and survival of this implant for at least one year of follow-up. Material and methodProspective study on 53 Isis® prosthesis, implanted from April 2014 to January 2019. The Van Cappelle functional test, pain, strength, mobility, return to previous activity, radiological variables and placement of the trapezial component were evaluated. The surgical technique was performed with a guide wirefocused on the trapezius and control of the scopia. Observed complications were recorded and statistical analysis was performed. ResultsFifty-one implants (49 patients) were reviewed. Mean follow-up was 2.1 years (1–5.7). Van Cappelle’s test, pain, mobility, and grip and clamp strength improved significantly, as did the distance between the metacarpal head and the trapezius base; 96% of the patients returned in less than 6 months to their activities. Minor complications, 3 De Quervain’s tendinopathy and 2 intra-operative metacarpal and 2 trapezium fractures were recorded, and one carpal tunnel syndrome. There was no dislocation, mobilization, or implant infection. ConclusionsThe functional results of the Isis® prosthesis are excellent in the short term, far exceeding the first year of 100% of survival. The complications that arose were minor and few. The anchorage and placement of the trapezial component guided by scopia seem to be crucial for the good result.

Touch® double mobility arthroplasty for trapeziometacarpal osteoarthritis: outcomes for 92 prostheses

Trapeziometacarpal prostheses have been used in the treatment of first carpometacarpal joint osteoarthritis for many years. No studies have demonstrated statistical superiority over gold-standard trapeziectomy, but they have been proved to enable shorter convalescence, better pain relief and faster functional recovery. The aims of the present study were to report functional results in a large cohort treated with the Touch® new-generation dual mobility trapeziometacarpal prosthesis, with comparison to results in the literature. A retrospective study included 92 Touch® prostheses. Assessment comprised pre- and post-operative pain, QuickDASH score and satisfaction rate. Mean follow-up was 1.33 ± 0.4 years. Pain significantly improved after surgery. Functional QuickDASH scores did not significantly differ from those reported in the age-matched general population. Return to work was fast, at 2.6 months. Satisfaction scores were high. There were no major complications such as dislocation, fracture or loosening, but the rate of De Quervain’s tenosynovitis was higher than in other studies. The Touch® prosthesis appeared to be a safe and stable implant, providing good satisfaction and very good functional scores and fast return to work and leisure activity. Considering the high rate of postoperative De Quervain’s tenosynovitis, we suggest opening the first sheath of the extensors tendons while positioning the prosthesis.

Surgical approaches to the trapeziometacarpal joint for the insertion of implants and prostheses (non-arthroscopy)

The two approaches most often used for placing implants and trapeziometacarpal prostheses are the laterodorsal approach and the lateropalmar approach. The advantages and disadvantages of these two approaches are set out. Each one allows optimal joint exposure while preserving or repairing the peritrapezial musculotendinous structures. They allow the insertion of partial or total trapeziometacarpal implants and modern coupled trapeziometacarpal prostheses. Each approach must be practiced and mastered on cadaver specimens before being used for trapeziometacarpal surgery.

Nouveautés médicales et prise en charge chirurgicale dans l’arthrose digitale

Hand osteoarthritis (OA) is a very frequent and heterogeneous disease. Its medical management is currently based on European recommendations and includes pharmacological (topical NSAIDs, and infiltrations) and non-pharmacological measures (orthotics, and ergonomics). Conventional synthetic or biological treatments used in rheumatoid arthritis have not demonstrated any efficacy. The only positive trial in recent years is low-dose corticosteroid therapy, which has demonstrated a suspensive effect. However, new therapeutic options such as botulinum toxin infiltrations or vagus nerve stimulation are currently being evaluated. As far as surgical treatment is concerned, arthrodesis remains the intervention of choice for distal interphalangeal OA and new fixation methods allow immediate mobilization. At the proximal interphalangeal level, joint denervation is an interesting conservative solution, while the best functional result is obtained with a prosthesis. The new models of resurfacing implants give higher amplitudes than hinged silicone implants, but we do not yet have the hindsight we have for the latter. For thumb base OA, trapezectomy with or without suspension ligamentoplasty has been confronted in recent years with severe competition from trapeziometacarpal prostheses, which allow faster functional recovery despite a higher complication rate and a long-term survival that is still poorly known. In total, surgical decision-making is based on multiple factors: functional demand of the patient, stability of the osteoarthritic joint, radiographic anatomical parameters.

Scaphometacarpal arthroplasty: a report of ten cases of trapeziometacarpal prosthesis and trapeziectomy revision.

Loosening of the trapezial component is a main cause of failure of trapeziometacarpal prostheses. This report presents the preliminary results of scaphometacarpal prostheses used for revision of trapeziometacarpal prostheses and failed trapeziectomies. A retrospective multicentre study was conducted on ten patients. Four had revision surgery after failure of trapeziometacarpal prostheses, five after trapeziectomy and one after a trapezial silicone implant. Pain, mobility, strength, QuickDASH, satisfaction score and radiographs were assessed. Nine patients were assessed (one was lost to follow-up), with a mean follow-up of 34 months. The mean pain score was 1.2/10, Quick-DASH was 39 and opposition according to the Kapandji score was 8.6. Strength was 3 kg for key pinch and 13.6 kg for power grip. One failure was observed, with early loosening of the scaphoid cup. Scaphometacarpal arthroplasty is a reliable medium-term solution for revision of the loosening of a trapeziometacarpal prosthesis with trapezial damage and for failed trapeziectomy. Level of evidence: IV.

Results of 110 IVORY® prostheses for trapeziometacarpal osteoarthritis with a minimum follow-up of 10 years.

The IVORY® prosthesis is a total trapeziometacarpal joint prosthesis used for the treatment of symptomatic trapeziometacarpal osteoarthritis. The aim of this prospective study was to evaluate its long-term outcomes with a minimum follow-up of 10 years. From 2004 to 2007, 110 trapeziometacarpal prostheses (95 patients) were implanted. The implant survival curve was constructed using the Kaplan-Meier method. Five patients were lost from follow-up and two died. Six prosthesis (5.5%) were removed after dislocation or fracture of the trapezium. The survival rate of the prosthesis was 95%. After 10 years, the mean visual analogue pain score was 0.24/10 and the key-pinch force was similar to the other hand. Dislocations occurred for eight implants (7.3%). No radiological loosening was noted. In conclusion, the long-term results with the IVORY® prosthesis are very satisfactory in terms of pain relief, function and survival. Level of evidence: II.

Courbes de survie à plus de 10 ans des prothèses trapézo-métacarpiennes: à propos de 294 cas

Thumb carpometacarpal osteoarthritis affects many post-menopausal women. If medical treatment fails, the most common options are trapeziectomy and trapezio-metacarpal arthroplasty. The purpose of this study was to evaluate the survival rate of trapezio-metacarpal prostheses in surgical treatment of thumb carpometacarpal osteoarthritis, and to highlight potential risk factors of unfavorable outcome. We performed a retrospective study involving 294 trapezio-metacarpal prostheses in 245 patients, who underwent surgery between 2001 and 2016. Clinical assessment was performed by self-questionnaire including pain, satisfaction, recovery time, QuickDASH Score, and opposition according to Kapandji score. Thumb X-rays were used to evaluate implant loosening sign, periprosthetic remodeling, and arthrosis of over and underlying joints. Implants survival rate at the final follow-up of 17.3 years was 90.8 % (95 % CI [85.8–96.1]). Median pain was 1 on 10 on VAS scale (0–8). Median QuickDASH Score was 20 (0–82), median opposition according to Kapandji was 9 on 10 (3–10). Median return to work time was 2 months (1–12). We identified 7.8 % of major complications, including 3.4 % of dislocations, 3.1 % of implants loosening, and 1 % of fractures. All dislocations involved surgical revision. Only few publications show results with more than 100 trapezio-metacarpal prostheses. Our results are consistent with existing studies. Trapeziectomy represents currently the gold standard in surgical treatment of thumb carpometacarpal osteoarthritis. Long-term superiority has not been proven in recent meta-analysis. Two recent studies found superiority of arthroplasty at short term concerning pain, strength, mobility, satisfaction, and recovery time, with similar complication rates. Trapezio-metacarpal arthroplasty is a long-term reliable solution for surgical treatment of thumb carpometacarpal osteoarthritis, with a limited complication rate.
