Minimum 10-year clinical and radiological follow-up of trapeziectomy with interposition or suspensionplasty for basal thumb arthritis

Resection arthroplasty versus dual mobility prosthesis in the treatment of trapeziometacarpal joint osteoarthritis: A 3 year non-randomized prospective study

Purpose

Resection arthroplasty (RA) is still the most common surgical intervention for the treatment of symptomatic trapeziometacarpal (TMC) joint osteoarthritis. The implantation of a dual mobility prosthesis may represent a joint function preserving alternative. The aim of the presented study is to prospectively compare the outcomes of RA with dual mobility prosthesis.

Methods

In this 2-center non-randomized prospective study, we compared results of RA (n = 22) with implantation of a dual mobility prosthesis (n = 49) (Touch®) at a minimum of 3-year follow-up. The patients underwent preoperative assessments and postoperative follow-up at 6 weeks, 3, 6, 12, 24, and 36 months. Comparisons were conducted, covering pain assessment via the visual analogue scale (VAS), thumb range of motion (ROM), pinch and grip strength, as well as functional scores and radiological examinations.

Results

The time intervals from surgery until absence of pain on the VAS (3 months: 3 vs 1, p = 0.0001), recovery of ROM in radial (3 months: 33° vs 42°, p = 0.0001), and palmar abduction (3 months: 33° vs 48°, p = 0.0001), were significantly longer for the RA group compared with the prosthesis group. At 3-year follow-up there was no significant difference in absence of pain, ROM and grip strength between both groups. Key pinch strength was significantly weaker in the RA group compared to prosthesis group at 3 months (2.6 kg vs 4.6 kg, p = 0.001), to 3-year follow-up (3.1 kg vs 5.7 kg, p = 0.0001). The final mean DASH (15.5 vs 13.2, p = 0.01) and MHQ scores (78 vs 82, p = 0.01) were significantly better in the prosthesis group.

Conclusion

Both techniques show high patient satisfaction in mid-term follow-up. Dual mobility TMC joint arthroplasty seems to be associated with a superior pinch strength and shorter time of recovery as compared to patients after RA.

MAÏA Trapeziometacarpal Joint Arthroplasty: Clinical and Radiological Outcomes of 76 Patients With More Than 10 Years of Follow-Up

PURPOSE

Trapeziometacarpal (TMC) joint replacement has become a valid option in the therapeutic arsenal of TMC joint osteoarthritis in Europe. Good mid-term results of the MAÏA TMC joint prosthesis suggested that it is a reliable procedure. This study aimed to assess the long-term results of this modular uncemented ball-and-socket hydroxyapatite-coated implant.

METHODS

This single-center retrospective study evaluated 92 MAÏA TMC joint prostheses in 76 patients with a minimum of 10 years of follow-up. Indications for the procedure were painful TMC joint osteoarthritis both at rest and during activity, despite nonsurgical treatment for more than six months. Pre- and postoperative clinical and radiographic outcomes were compared.

RESULTS

Mean follow-up was 134 months (range: 120-158 months). Mean age at the time of surgery was 67 years (range: 53-84 years). The cohort comprised 86.8% of women (n = 66). The mean Quick Disabilities of the Arm, Shoulder, and Hand score improved from 61.3 ± 17.1 to 19.6 ± 16. Range of motion was restored, and postoperative mobility was comparable with that of the contralateral side. Final Kapandji opposition score was almost normal (9.2 ± 0.7). Final key pinch and grip strength improved by 26% and 39%, respectively. Eight implants were surgically revised, six for trapezium cup loosening and two for instability because of polyethylene wear. Three cases of traumatic fracture of the trapezium in older patients were successfully treated with a cast for eight weeks. Five of 26 (20.8%) cases of preoperative-reducible z-deformity were not totally corrected after surgery. The Kaplan-Meier survival over 10 years was 88% (95% confidence interval: 84-93) versus 93% (95% confidence interval: 87-98) over 5 years.

CONCLUSIONS

MAÏA TMC joint prosthesis is a reliable long-term surgical procedure for TMC joint osteoarthritis, improving overall function beyond 10 years.

Simple trapeziectomy for thumb basal joint arthrosis. Forty-four thumbs re-reviewed after 7.5 years

Background

Due to favorable results in the literature we changed our standard procedure in 2010 from trapeziectomy with LRTI to simple trapeziectomy for thumb basal joint arthrosis. A review of 49 operated hands after two years showed good results, similar to those we had obtained after LRTI.

Objective

We have now re-reviewed these patients to see if the good results persist over time.

Methods

All patients from the earlier study were contacted and 40 patients with 44 operated thumbs were re-reviewed after a mean of 7.5 years.

Results

The mean pain score (0-100) was 14 (SD:22) compared to 18 (25) at the earlier review. There was no significant change in ability to perform ADL activities between reviews. Mean VAS (0-100) for clumsiness fell significantly between early and late review (67 (SD:18) versus 45(27); p ​< ​0.019), although clumsiness was reported by an increased number of patients. VAS for general satisfaction had improved from 23 (SD:28) to 13 (22) between reviews (p ​< ​0.01). The mean QuickDASH and PRWHE scores were practically unchanged. There was significantly improved thumb abduction and ulnar/radial deviation at the wrist. There was a significant reduction in power grip and key pinch in both the operated and the contralateral un-operated hands compared to the earlier review. Radiographs showed a slightly reduced mean distance between the first metacarpal and the scaphoid.

Conclusion

We conclude that the good results after simple trapeziectomy persist.

Long-term outcomes of trapeziectomy with Gore-Tex® ligament reconstruction for trapezio-metacarpal osteoarthritis

BACKGROUND

Trapezio-metacarpal osteoarthritis is a common condition for which the reference standard treatment after failure of non-operative measures is trapeziectomy. Several techniques have been devised to avoid proximal migration of the first metacarpal bone (M1) with impingement on the scaphoid bone. We have developed a Gore-Tex® ligament reconstruction technique that avoids potential complications of tendon harvesting. The objective of this study was to assess the long-term outcomes of this technique.

HYPOTHESIS

Trapeziectomy with Gore-Tex® ligament reconstruction is a reliable option for providing lasting pain relief in patients with trapezio-metacarpal osteoarthritis.

MATERIALS AND METHODS

We conducted an observational, single-centre, single-surgeon, retrospective cohort study in consecutive patients managed by primary trapeziectomy. We excluded patients with revision trapeziectomy or less than 10 years' follow-up. The primary outcome was event-free survival, defined as absence of revision surgery and of a numerical rating scale score for pain above 3/10. The secondary criteria were clinical tolerance of the Gore-Tex® implant and radiological changes. The patients were assessed at last follow-up either in person or during a teleconsultation.

RESULTS

Of 78 included joints, 54 were assessed during patient visits and 24 by teleconsultation. At 10 years, the event-free survival rate was 91.3%, and 60.3% of patients were free of pain. Evidence of osteolysis was visible in 24% of patients. No patient experienced clinical intolerance of the Gore-Tex® implant. The mean Disabilities of Arm, Shoulder and Hand score was 25.5. Metacarpo-phalangeal hyperextension was significantly increased, to 30.6°, and the mean trapezial space ratio was significantly decreased, to 39.1% of the baseline value.

CONCLUSION

Long-term event-free survival was high. Functional outcomes and pain were similar to previous reports. Trapeziectomy with Gore-Tex® ligament reconstruction obviates the need for tendon harvesting. Osteolysis developed in some patients but did not correlate with clinical intolerance. Long-term clinical and radiological monitoring is in order after Gore-Tex® implantation.

Thumb basal joint arthritis in 2023

Thumb carpometacarpal or basal joint arthritis is the second most common location for osteoarthritis in the hand. It mainly affects women over 50years of age. Basal joint arthritis causes pain, loss of strength during pinch grips, and eventually stiffness and progressive deformity of the thumb column. Conservative treatment must be implemented first. It aims to spare the joint by using standardized methods. It must be initiated as soon as pain starts, not once the deformity has settled in. There is broad agreement that surgery is indicated when pain relief is not achieved after at least 6months of conservative treatment. The available surgical techniques can be classified as joint-sparing (extra-articular) and joint-sacrificing (intra-articular). The former consists of trapeziometacarpal stabilizing ligament reconstruction, subtraction osteotomy of the first metacarpal and thumb carpometacarpal denervation. The latter consists of trapeziometacarpal fusion, trapeziectomy (and its variants) and implant arthroplasty. Except in very specific cases, trapeziectomy and trapeziometacarpal implant arthroplasty with a total joint prosthesis or an interposition implant are the two main surgical techniques for treating basal joint arthritis. After reviewing the pathophysiology and the diagnosis of thumb basal joint arthritis, we will provide an overview of the available treatment options, with emphasis on the accepted surgical strategies in 2023.

Total joint arthroplasty versus trapeziectomy in the treatment of trapeziometacarpal joint arthritis: a randomized controlled trial

The aim of this double anonymized, randomized controlled trial was to determine whether total joint arthroplasty has superior outcomes than trapeziectomy 1 year after surgery for trapeziometacarpal osteoarthritis. A total of 62 women aged 40 years and older, scheduled for surgery for stage II or III osteoarthritis of the trapeziometacarpal joint, were included and randomized to trapeziectomy or total joint arthroplasty. The primary outcome was the total score of the Michigan Hand Outcomes Questionnaire. Secondary outcomes were the Michigan Hand Outcomes Questionnaire subscale scores, Disability of the Arm, Shoulder and Hand Questionnaire, active range of motion, strength, return to work, patient satisfaction and complications. Data were collected at baseline and at 3 and 12 months. At 1 year, we found no superiority of total joint arthroplasty over trapeziectomy regarding the total score of the Michigan Hand Outcomes Questionnaire. The total joint arthroplasty did show a significant advantage in strength and range of motion.Level of evidence: I.

Primary trapeziectomy with Regjoint(TM), a poly-L/D-lactide spacer, a two-year follow-up study with new radiological assessment tool

The aim of this retrospective study was to evaluate the potential bony erosion and the clinical and radiological results of primary trapeziectomy with RegjointTM interposition, in patients with peritrapezial arthritis. Data were recorded on twenty patients over a period of two years (January 2015-December 2016). On average 24 months, patients were reconvened for a post-operative evaluation (subjective evaluation of pain, function and patient satisfaction; clinical evaluation with strength and mobility measures; post-operative X-rays). On X-rays, 2 criteria were evaluated: the bony erosion and the shortening of the thumb column (trapezium+metacarpal height measure, ratio between first and second metacarpal bones, a new radiological assessment tool based on a trapezoid relationship gradation). In most patients, surgery relieved pain and offered good functional results, according to the Quick Disabilities of the Arm, Shoulder and Hand scale. Following surgery, our patients showed a subjective improvement, both in terms of pain and functional results. For plain X-ray, only 3 patients showed an osteolytic lesion (maximum of 2.8 millimeters) on the first metacarpal base. A statistically significant reduction in the thumb column height was generally observed on follow-up X-rays. However, all of these radiologic changes were present without any clinical impact. We show that the RegjointTM spacer is an available alternative in the surgical treatment of peritrapezial arthritis. We did not highlight any significant associated complications, no important adverse tissue reaction or bone erosion, no pain or functional disorder. Type of study/level of evidence Therapeutic IV.

Trapeziectomy with or without a tendon-based adjunct: a registry-based study of 650 thumbs

This study aimed to assess the outcomes after simple trapeziectomy and trapeziectomy with ligament reconstruction and/or tendon interposition based on data in the Swedish national healthcare quality registry for hand surgery (HAKIR). Six-hundred and fifty thumbs were included, and 265 were assessed up to 12 months after operation. There was significant and clinically relevant improvement in patient-reported measures (pain on load, pain on motion without load, pain at rest, stiffness, weakness, and ability to perform activities of daily living and the Quick Disabilities of the Arm, Shoulder and Hand score) and objective measures (strength and thumb mobility) at 3 and 12 months for all procedures. The use of the abductor pollicis longus tendon had better improvement in some respects compared with the use of flexor carpi radialis or extensor carpi radialis tendons. However, overall, the use of a tendon adjuncts yielded no better outcomes than simple trapeziectomy.Level of evidence: III.

What Are the Patient-reported Outcomes of Trapeziectomy and Tendon Suspension at Long-term Follow-up?

BACKGROUND

There are multiple options for the treatment of thumb carpometacarpal joint osteoarthritis (CMC1 OA), with evidence for pain relief and improved function. Although simple trapeziectomy has the lowest complication risk, tendon suspension of the first metacarpal and interposition is still the most commonly used surgical procedure in patients with CMC1 OA. Although there are several reports of good short-term results after trapeziectomy and tendon suspension-interposition arthroplasty, few studies have evaluated long-term outcomes. This study is one of the largest and longest follow-up evaluations of a cohort of patients with CMC1 OA who were treated with trapeziectomy and suspension-interposition arthroplasty, capturing 96% of the original cohort for evaluation.

QUESTIONS/PURPOSES

(1) After trapeziectomy and tendon suspension surgery, what are the long-term, patient-reported outcomes and clinical measurements (strength and ROM); and in unilateral procedures, how do these parameters compare with those of the contralateral hand that was not operated on? (2) What is the mean subsidence (unloaded trapezial space), and does pinch strength correlate with the amount of subsidence?

METHODS

From 1998 to 2005, 130 patients underwent trapeziectomy and abductor pollicis longus (APL) suspension-interposition arthroplasty for CMC1 OA at one orthopaedic department. During this period, 15 patients were treated with CMC1 arthrodesis and four were treated with implant arthroplasty, for a total of 149 patients. The surgeons used APL suspensionplasty for most patients, based on age and expected postoperative function; they also employed this procedure to avoid hardware or implant failure issues. The 100 living patients were asked to participate in this retrospective study, 96% (96) of whom were enrolled. The mean age at surgery was 58 ± 7 years. The patients completed a two-item thumb pain scale (modified from the SF-36 body pain scale), a hand pain VAS (average level of pain experienced over the week preceding measurement), and the 11-item QuickDASH. Patient-reported outcomes data were obtained from all 96 patients, and 83% (80) of patients underwent bilateral hand radiography and a physical examination at a mean follow-up of 17 ± 2.4 years. We calculated outcome data for each patient, and in 39 patients with unilateral surgery and intact contralateral CMC1 joint, we compared the operated side with the contralateral side. We compared our outcome data with that from the Swedish National Quality Registry for Hand Surgery (HAKIR), noting comparable outcomes for pain and QuickDASH scores.

RESULTS

At long-term follow-up after trapeziectomy and APL suspension surgery, the mean thumb pain score was 19 ± 26, hand pain VAS score 23 ± 25, and QuickDASH score 26 ± 21. In the patients with unilateral surgery and intact contralateral CMC1 joint, the thumb pain score for the operated side was lower than the contralateral side, specifically 19 ± 25 compared with 29 ± 30 (mean difference -9.8 [95% CI -19.5 to -0.2]; p = 0.045); hand pain VAS score was 24 ± 23 versus 30 ± 25 (mean difference -6.1 [95% CI -15.2 to 3.1]; p = 0.19), and the QuickDASH score was 27 ± 19. Grip strength showed no differences between the operated and contralateral sides (mean 16.7 ± 7.3 kg versus 16.6 ± 6.9 kg, mean difference 0.1 [95% CI -1.6 to 1.8]; p = 0.90), while pinch was different (4.4 ± 1.4 versus 5.0 ± 1.5 kg, mean difference -0.6 [95% CI -0.9 to -0.3]; p = 0.001). The mean trapezial space was 4.4 ± 2.2 mm, and there was no association between the trapezial space and pinch strength (0.07 kg [95% CI -0.04 to 0.18] per mm of space; p = 0.17).

CONCLUSION

The finding of comparable pain and function between operated and unoperated sides at long-term follow-up suggests that trapeziectomy and tendon suspension-interposition arthroplasty provides predictable outcomes, and surgeons can use these data to counsel patients that surgery can potentially return them to comparable use. However, as patients often have asymptomatic radiographic OA on the contralateral side, future studies are needed to examine the impact of asymptomatic disease on function.

Efficacy of Surgical Interventions for Trapeziometacarpal (Thumb Base) Osteoarthritis: A Systematic Review

Purpose

This systematic review (SR) aimed to identify the surgical interventions available for trapeziometacarpal osteoarthritis and document their efficacy on pain, physical function, psychological well-being, quality of life, treatment satisfaction, and/or adverse events.

Methods

This PROSPERO-registered SR's protocol was developed based on the Cochrane intervention review methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

Among 9049 potential studies identified, 1 SR, 18 randomized controlled trials, and 40 nonrandomized controlled trials were included. We identified 11 categories of surgical techniques: first metacarpal osteotomy, first metacarpal and trapezium partial resection, arthrodesis, trapeziectomy (T), T+ligament reconstruction (LR), T+tendon interposition (TI), T+ligament reconstruction and tendon interposition (LRTI), hematoma distraction arthroplasty (HDA), chondrocostal graft interposition, autologous fat injection, and manufactured implant use. These findings supported by low-quality evidence revealed moderately or largely superior effects of the following interventions: (1) trapeziectomy over T+LRTI using ½ flexor carpi radialis (FCR) and metacarpal tunnel (MT) or using abductor pollicis longus (APL) and FCR for adverse events; (2) trapeziectomy over T+TI using palmaris longus (PL) for pain; (3) T+LR with ½FCR-MT over T+LRTI with ½FCR-MT for physical function; (4) trapeziectomy by anterior approach over that by posterior approach for treatment satisfaction and adverse events; (5) T+LRTI using ½FCR-MT over T+TI with PL for pain; and (6) T+HDA over T+LR using APL-MT-FCR for pain, physical function, and adverse events. GraftJacket (Wright Medical Group, Memphis, TN), Swanson (Wright Medical Group, Letchworth Garden City, UK), and Permacol (Tissue Science Laboratories, Aldershot, UK) implants and hardware (plate/screw) would cause more complications than an autograft. The effect estimates of other surgical procedures were supported by evidence of very low quality.

Conclusions

This SR provided evidence of the efficacy of various surgical interventions for trapeziometacarpal osteoarthritis. Some interventions showed a moderate-to-large superior effect on the studied outcome(s) compared with others. However, these findings must be interpreted with caution because of low-quality evidence. To provide stronger evidence, more randomized controlled trials and methodological uniformization are needed.

Thumb carpometacarpal arthroplasty and trapeziectomy using a tenodesis screw compared to ligament reconstruction

This study aimed to compare the results of patients treated with a thumb carpometacarpal (CMC) suspension arthroplasty using an interference screw technique with patients that were treated by trapeziectomy and ligament reconstruction. A retrospective chart review was conducted of patients over 18 years old who required surgical treatment for thumb CMC joint arthritis treated by a single surgeon. Patients included in the study followed the same preoperative and postoperative protocol. Information related to functional outcomes was collected (pinch and grip strength, pain, Kapandji score, proximal migration of first metacarpal bone). One hundred and five patients were included, 77% were female, age at the time of the study was 62.7 years old; 74 (70%) patients were treated with the tenodesis screw (TS) technique and 31 (30%) with trapeziectomy and ligament reconstruction (TZLR). Patients were followed for a mean of 8.4 months. Postoperative pain was 1.2 in the TS group and 0.6 in the TZLR group; Kapandji score was 8.3 in the TS group and 9 in the TZLR group; in the TS group, the grip strength was 26.2kg and key pinch strength was 6.15kg; in the TZLR group, grip strength was 12.8kg and key pinch strength was 4.7kg. Proximal migration was 0.4cm in the TZLR group and 0.6cm in the TS group. The use of tenodesis screw and half of the flexor carpi radialis had minor advantages, such as increasing the grip and key pinch strength without differences relative the non-operated thumb, minimal migration of the first metacarpal bone compared with the other technique.

Does proximal migration of the first metacarpal correlate with remaining pain after trapeziectomy?

Proximal migration of the thumb metacarpal has been suggested as a possible cause of remaining pain after trapeziectomy for trapeziometacarpal joint osteoarthritis. The aim of this study was to investigate if proximal migration after trapeziectomy is associated with a poorer long-term outcome in terms of pain and objective physical variables. We retrospectively examined 91 thumbs in 65 patients after a mean of 10 years following trapeziectomy with or without ligament reconstruction and tendon interposition. Proximal migration of the thumb metacarpal was measured on plain lateral radiographs of the thumb and correlated to visual analogue pain scale (VAS), thumb range of motion and strength. Most thumbs had a severe proximal migration of the first metacarpal, the mean scaphoid metacarpal distance was 2.7 mm. Most patients reported no or little pain, median VAS was 0 at rest and 1 after load. There were no differences in reported VAS pain at rest or after load between patients with severe (<2 mm scaphoid metacarpal joint space) or less severe (≥2 mm metacarpal joint space) proximal migration. Patients that reported more pain (VAS >2) did not exhibit more migration than patients reporting less or no pain. Thumbs with severe migration had weaker key pinch (3.4 vs. 4.6 kg, p = 0.008) and grip strength (15 vs. 21 kg p = 0.002). We conclude that proximal migration most likely does not cause residual or recurrent pain after trapeziectomy.

Trapeziectomy for trapeziometacarpal osteoarthritis

Aims

The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up.

Methods

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded.

Results

All the studies reported good results regarding pain and range of motion at the last follow-up of 8.3 years (5 to 22); the mean satisfaction rate was 91% (84% to 100%). It was difficult to assess the impact on metacarpophalangeal joint motion in extension with contrary results. The key pinch returned to its preoperative values, whereas tip pinch showed a modest improvement (+14%), with a mild improvement found in grip strength (+25%) at the last follow-up. The mean progressive trapezial collapse was 48% (0% to 85%) and was not correlated with pain, grip strength, or satisfaction. The most represented complications were linked to tendons or nerves affected during additional procedures to stabilize the joint (11.6%; n = 56). Mechanical complications included symptomatic scapho-M1 impingement (3.1%; n = 15/580), leading to nine surgical revisions out of 581 trapeziectomies. Meta-analysis was not possible due to study heterogeneity and limited data.

Conclusion

After a minimum five-year follow-up, trapeziectomy achieved high patient satisfaction and pain relief. However, strength seemed to be deteriorating with detrimental consequences, but this did not correlate with trapezial collapse. The issues related to underestimating mechanical complications and varying degrees of success should be highlighted in the information given to patients. Evidence-based analyses should help the surgeon in their decision-making.

Simple trapeziectomy versus trapeziectomy with flexor carpi radialis suspension: a 17-year follow-up of a randomized blind trial

The purpose of this study was to investigate if there were any significant differences in the long-term outcomes of patients who participated in a randomized trial of trapeziectomy alone compared with trapeziectomy with ligament reconstruction and tendon interposition (LRTI). Sixty-five patients were invited for a follow-up visit at a mean of 17 years (range 15-20) postoperatively. Twenty-eight patients attended, who had 34 operations, 14 trapeziectomy alone and 20 with LRTI. There were no statistically significant differences between the two groups in terms of satisfaction with surgery or functional outcomes, with most measurements showing minimal or no differences in means between the two groups. There was no difference in the space between the metacarpal and scaphoid. Radial abduction was the only parameter that was significantly greater in the patients with simple trapeziectomy (median 79°) compared with trapeziectomy with LRTI (median 71°) (p = 0.04). Even at 17 years there is no significant benefit of LRTI over trapeziectomy alone for thumb carpometacarpal joint osteoarthritis.Level of evidence: I.

Trapeziometacarpal osteoarthritis and arthritis of the wrist

Although the simultaneous occurrence of arthritis of the wrist and the base of the thumb is rare, it is nonetheless imperative to carry out a preoperative clinical and radiological assessment of the wrist when managing trapeziometacarpal osteoarthritis. The presence of pre-arthritic lesions or established wrist arthritis, even if treated, must be taken into consideration when treating osteoarthritis at the base of the thumb. The coexistence of these lesions determines the entire surgical strategy. Failure to take them into account during the surgical treatment often results in a compromised postoperative course and it often adversely impacts the outcome of secondary surgeries.

Reporting Outcomes and Outcome Measures in Thumb Carpometacarpal Joint Osteoarthritis: A Systematic Review

PURPOSE

In the thumb carpometacarpal (CMC) joint osteoarthritis (OA) literature, there is substantial heterogeneity in outcome and outcome measure reporting. This could be rectified by a standardized core outcome set (COS). This study aimed to identify a comprehensive list of outcomes and outcome measures for thumb CMC joint OA, which represents the first step in developing a COS.

METHODS

A computerized search of MEDLINE, EMBASE, Cochrane, and CINAHL was performed to identify randomized controlled trials, as well as observational studies involving at least 50 participants aged greater than 18 years undergoing surgery for thumb CMC joint OA. Reported outcomes and outcome measures were extracted from these trials and summarized.

RESULTS

This search yielded 3,498 unique articles, 97 of which were used for analysis. A total of 33 unique outcomes and 25 unique outcome measures were identified. The most frequently used outcomes were complications (78), postoperative pain (73), radiologic outcomes (64), and grip strength (63). Within each reported outcome, there was substantial variation in how the outcome was measured. Of the 25 unique outcome measures, 10 were validated. Of the remaining 15, 12 were created ad hoc by the author. The Disabilities of the Arm, Shoulder, and Hand questionnaire was the most commonly reported outcome measure (34%).

CONCLUSIONS

There is a lack of consensus on critical outcomes after surgery for thumb CMC joint OA. A standardized COS created by stakeholder consensus would improve the consistency and therefore the quality of future research.

CLINICAL RELEVANCE

This systematic review of outcomes represents the first step in developing a core outcome set for thumb CMC joint OA.

Arpe total joint arthroplasty for trapeziometacarpal osteoarthritis: 80 thumbs in 63 patients with a minimum of 10 years follow-up

In this retrospective study, we report a series of 80 Arpe prostheses for trapeziometacarpal osteoarthritis in 63 patients. Twenty-seven prostheses (20 patients) were lost to follow-up. Twenty-one were revised, eight of them during the first year after operation. The calculated cumulated implant survival rate was 85% at 10 years but could be lower due to the lack of information on the patients lost to follow-up. The number of complications due to technical errors was high; but after we had done 30 cases, the number of early revisions decreased markedly. At follow-up, 23 of 32 thumbs were totally free of pain, and the patients were satisfied with 31 thumbs. We conclude that the implant survival declines progressively in the long run, with a survival rate of 80% after 15 years of follow-up and a further decline thereafter. We also found that this surgery was difficult to master. We advise selecting this implant for thumb trapeziometacarpal osteoarthritis with caution. Level of evidence: IV.

Total trapeziectomy for osteoarthritis of the trapeziometacarpal joint: Clinical and radiological outcomes in 21 cases with minimum 10-year follow-up

INTRODUCTION

Trapeziectomy is a technique of choice for osteoarthritis of the trapeziometacarpal joint, but few studies have assessed long-term radiological and clinical outcome in total trapeziectomy, mean follow-up being rather between 2 and 6 years in most cases. The main aim of the present study was to assess loss of trapezial space height at a minimum 10 years' follow-up. Secondary endpoints comprised functional outcome at the same follow-up.

HYPOTHESIS

There is systematic loss of trapezial space height, with discrepancy between radiological and clinical results, beyond 10 years' follow-up.

MATERIAL AND METHODS

Sixteen patients were retrospectively reassessed at a mean 13.8 years' follow-up (range, 10-17.8 years), for 21 total trapeziectomies. Criteria for the main endpoint comprised trapezial space height (TSH) and trapezial space ratio (TSR=TSH/thumb P1 phalanx length). Secondary endpoint criteria comprised pain, Kapandji opposition and retropulsion scores, active abduction, dynamometric parameters (key-pinch, tip-pinch and grip strength compared to the contralateral side), QuickDASH and satisfaction.

RESULTS

Mean TSH and TSR were respectively 3.7mm (range, 0.5-6.1) and 0.14 (0.02-0.25) at last follow-up. Ranges of motion were conserved, with mean Kapandji score of 9.3 (6-10), Kapandji retropulsion score of 2.8 (1-4) and active abduction of 43° (30-45°). Strength measurements were comparable to contralateral values except for key-pinch, which was significantly weaker on the operated side (4.8kg (1.5-8.5kg) versus 5.5kg (1.5-8kg); p=0.041). Mean QuickDASH was 23.5 (0-68.2), and overall satisfaction on VAS was 9.5/10 (6-10). Statistical testing confirmed the absence of correlation between radiological and clinical criteria.

DISCUSSION

Despite systematic trapezial space height loss, functional results were satisfactory and stable at a mean follow-up of 13.8 years. There was no correlation between radiological and clinical criteria in the long term.

Trapeziectomy with LRTI or joint replacement for CMC1 arthritis, a randomised controlled trial

We compared an uncemented joint replacement (Elektra) with trapeziectomy (with ligament reconstruction and tendon interposition, LRTI) for the treatment of primary osteoarthritis in the first carpometacarpal joint (CMC1) in a randomised controlled trial. Forty patients were included (20 in each group) and followed for 2 years. The median age in the groups was 64 and 61, respectively, with 14 females in each. At final follow-up, there was no difference in the primary outcome measure (the quick disabilities of the arm, shoulder and hand score, QDASH), but the joint replacement group had significantly better motion and strength during the early rehabilitation period and significantly better range of thumb abduction and extension at the last follow-up. There were more complications in the joint replacement group with revision of prosthetic components in five cases, two of them due to cup loosening. Radiologically, lucency zones were seen around either cup or stem in 15 patients. Most were small, but two cases with major osteolysis resulted in revision. Shortening of the thumb ray was observed after trapeziectomy.

Maïa® trapeziometacarpal joint arthroplasty: Survival and clinical outcomes at 5 years' follow-up

We sought to report the clinical and radiological outcomes and the survival of Maïa^® trapeziometacarpal joint arthroplasty retrospectively at a mean 5 years' follow-up. We evaluated the implant survival and the clinical outcomes of 93 patients (113 prostheses). Patients were examined during a consultation and their mobility, key pinch strength and satisfaction were recorded. Patients also completed a QuickDASH evaluation. The 5-year survival rate was 92.2%. The mean QuickDASH Score was 26.7. The complication rate was 31% and the revision rate was 12.4%. The most common complication was dislocation and the most frequent cause of surgical revision was periprosthetic ossification. We identified two cases of aseptic loosening. This study shows the Maïa^® prosthesis provides satisfactory medium-term results and has an excellent 5-year survival. However, the high complication and revision rates are still a major concern.

Results of the treatment of first carpometacarpal joint osteoarthritis: trapeziectomy alone versus trapeziectomy associated with suspensionplasty

BACKGROUNDS

The goal of this study was to compare trapeziectomy alone to trapeziectomy associated with a technique of suspensionplasty using the abductor pollicis longus with a minimum of 6 years of follow-up in the treatment of osteoarthritis of the first carpometacarpal joint.

METHODS

Our series included 46 trapeziectomies in 35 patients, aged 69 years in average, among which 27 were women. In 27 cases group I, a trapeziectomy alone was performed, and in 19 cases group II, a trapeziectomy associated with an abductor pollicis longus suspensionplasty was performed.

RESULTS

At the last follow-up, the difference between pre- and postoperative Quick DASH was - 36.104 in average in group I and - 38.877 in average in group II p = 0.7717. The difference between pre- and postoperative pain was - 3.926 in average in group I and - 4.368 in average in group II p = 0.35. The difference of pre- and postoperative thumb opposition was 0.630 in group I and 0.421 in group II p = 0.3033. The average difference of pre- and postoperative key pinch was 0.389 in group I and 0.842 in group II p = 0.3303. No complication was reported.

CONCLUSIONS

Our results suggest that it is unnecessary to perform a ligamentoplasty when a trapeziectomy is indicated.

MAÏA Trapeziometacarpal Joint Arthroplasty: Clinical and Radiological Outcomes of 80 Patients With More than 6 Years of Follow-Up

PURPOSE

Trapeziometacarpal (TMC) total joint replacement is increasingly being performed in Europe. MAÏA TMC total joint arthroplasty is a modular uncemented ball-and-socket hydroxyapatite-coated implant. This study assessed the midterm clinical and radiological results of the MAÏA TMC prosthesis.

METHODS

This single-center retrospective study involved 80 patients who underwent 96 MAÏA TMC prosthesis implantations from February 2006 to April 2009, and who had a minimum of 5 years' follow-up. Indications for the procedure were painful TMC joint osteoarthritis affecting activities of daily living and a failure of at least 6 months of nonsurgical treatment. Pre- and postoperative clinical and radiographic data were reviewed.

RESULTS

The mean age at surgery was 68 years (range, 53-84 years) and the median follow-up was 76 months (range, 60-102 months). The mean Quick Disabilities of the Arm, Shoulder, and Hand score improved from 61.3 ± 17.1 to 17.5 ± 16. The mobility of the thumb was restored to a range of motion comparable with that of the contralateral thumb. Opposition, defined by the Kapandji score, was almost normal (9.2 of 10; range, 6-10), as was the final mean key pinch and grip strength, which improved by 26% and 43%, respectively. Among the 96 implants, 4 (4.2%) were surgically revised for trapezium loosening. One dislocation was treated with closed reduction; 3 (3.1%) posttraumatic trapezium fractures were immobilized for 8 weeks. Among the 26 preoperative reducible z-deformities, only 5 (19.2%) were not totally corrected after surgery. The procedure success, by survival analysis over 6 years, was 93% (95% confidence interval, 87-98).

CONCLUSIONS

MAÏA TMC total joint arthroplasty may be a reliable treatment option for TMC joint osteoarthritis, with very good results for pain relief, strength, mobility, and restoration of the thumb length, providing correction of most thumb z-deformities.
