RESUMEN
Background: Osteoarthritis of the carpometacarpal (CMC) is considered a common musculoskeletal disorder. The treatment of carpometacarpal osteoarthritis could be either by conservative or surgical methods. surgical treatment, there are various alternatives, including trapeziectomy and arthroplasty. This study aims to perform a systematic review of the literature to determine the functional outcomes associated with trapeziectomy and arthroplasty in CMC arthritis. Objectives: To determine the functional outcomes associated with trapeziectomy and arthroplasty in CMC arthritis patients. Methods: A systematic review was conducted according to PRISMA guidelines and performed on August 2022 by one independent reviewer (author) using PubMed database, EBSCO Host, EMBASE, and ScienceDirect. The literature search will be based on Patients, Intervention, Control, and Outcome (PICO) criteria, as mentioned in the following: Patients with any carpometacarpal arthritis; with the intervention of using carpometacarpal arthroplasty as their method of surgery; control with trapeziectomy and primary outcome of functional outcome. Clinical outcomes using patient-reported outcome measures and complications were included. The quality of the included studies was evaluated with Cochrane risk-of-bias assessment tools. Quantitative analysis was performed by Review Manager 5.4. Results: Three studies met the inclusion criteria for the systematic review. Both treatments resulted in significant improvements in functional scores. When matching patients according to preoperative function, patients receiving arthroplasty had better postoperative function (Quick DASH: trapeziectomy = 25.1, ARPE = 16.8). Conclusion: This study showed that variable results of clinical outcomes improved after trapezeictomy and arthroplasty in patients with CMC arthritis. Evidence showed that arthroplasty allows for a better improvement in functional outcome.
RESUMEN
BACKGROUND: The purpose of this individual cohort study is to demonstrate safety and efficacy in removing the trapezium through minimally invasive arthroscopy. METHODS: A prospective case series was performed on all arthroscopic total trapeziectomy procedures for thumb basal joint arthrosis between 2018 and 2022. Patients were followed for up to 1 year. All patients received an examination at each visit to include pain, range of motion, strength, and metacarpal height. Complications, concomitant procedures, and revision procedures were recorded as well. RESULTS: A total of 49 arthroscopic trapeziectomy procedures were recorded for 46 patients. The average preoperative visual analog pain scale score was 8.8 out of 10, and the postoperative score was 1 out of 10. All patients had a resolution of the carpometacarpal grind test postoperatively. The average preoperative key pinch, 3-point chuck, and grip strength were 9.8 lbs/in2, 7.8 lbs/in2, and 45 lbs/in2, respectively. Final 6-month postoperative key pinch, 3-point chuck, and grip strength were 11.0 lbs/in2, 9.8 lbs/in2, and 49.2 lbs/in2, respectively. Metacarpal height subsided on average 50%. We report one revision and no cases of radial sensory neuritis or flexor tendon rupture. CONCLUSIONS: Arthroscopic total trapeziectomy appears to be a safe and effective treatment for end-stage arthrosis of the thumb basal joint. LEVEL OF EVIDENCE: 2b Therapeutic; Individual Cohort Study.
RESUMEN
BACKGROUND: Primary thumb carpometacarpal (CMC) osteoarthritis is one of the most common conditions encountered by hand surgeons. Of the vast number of operations that have been proposed, none have demonstrated results significantly superior to trapeziectomy alone. AIM: The purpose of our study was to determine why surgeons opt for their technique in treating CMC arthritis. METHODS: A cross-sectional survey of active members of the American Society for Surgery of the Hand was conducted to evaluate the reasons behind their preferred technique in the treatment of isolated thumb CMC arthritis. Surgeons were contacted by e-mail once and provided with a link to a de-identified survey consisting of 5 treatment questions and 5 demographic questions. RESULTS: Of 950 responses were received. 40.5% of surgeons preferred trapeziectomy + ligament reconstruction tendon interposition (LRTI), followed by trapeziectomy + suspensionplasty (28.2%), suture button suspension (5.9 %), trapeziectomy alone (4.6%), prosthetic arthroplasty (3.2%), arthrodesis (1.1%), and other (6.6%). Proponents of trapeziectomy + LRTI cited familiarity (73.2%), exposure during fellowship (48.8%) and less proximal migration (60%) to be the main reasons affecting their decision. Surgeons who preferred trapeziectomy + suspensionplasty most reported simplicity (74.9%), fewer complications (45.3%), less proximal migration (43.8%), and avoidance of autogenous tissue harvest (42.7%). Advocates of suture button suspension cited avoidance of autogenous tissue harvest (80.4%), shorter immobilization (76.8%), and quicker recovery (73.2%) with their technique. Advocates of trapeziectomy alone cited simplicity (97.7%), fewer complications (86.4%), and avoidance of autogenous tissue harvest (59.1%). In their comments, 45% of surgeons choosing trapeziectomy alone cited evidence as an additional rationale. Advocates of prosthetic arthroplasty cited improved pinch strength (83.3%) and improved range of motion (63.3%), while those preferring arthrodesis cited better pinch strength (90%) and frequently in their comments, durability. Of the surgeons who preferred a technique other than LRTI, 41.8% reported they had tried LRTI in the past, citing complexity of the procedure, flexor carpi radialis harvest, and longer operative time as reasons for moving on. CONCLUSION: Our study provides an update on current treatment trends and offers new insight into the reasons behind surgeons' decision making in the management of thumb carpometacarpal osteoarthritis. Despite strong Level 1 evidence supporting the use of trapeziectomy alone, our findings demonstrate that most surgeons continue to supplement trapeziectomy with other techniques such as LRTI or suspensionplasty. Several factors including familiarity, personal experience (Level 4 evidence), and comfort may be more influential than Level 1 evidence in determining the techniques in a surgeon's armamentarium. Further prospective studies are needed to determine the optimal technique for surgical management of Eaton stages II-IV CMC arthritis and how these studies will affect surgeons' choice.
RESUMEN
OBJECTIVES: De 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. METHODS: We reviewed a series of 331 trapeziometacarpal prostheses. RESULTS: There 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. CONCLUSIONS: We 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.
RESUMEN
PURPOSE: We performed a randomized controlled trial assessing patient-reported outcome measures following trapeziectomy with ligament reconstruction and tendon interposition (LRTI) or suture tape suspensionplasty (STS) for treatment of thumb carpometacarpal joint osteoarthritis. METHODS: Patients undergoing surgery for thumb carpometacarpal joint osteoarthritis were prospectively randomized to LRTI or STS. Outcome measures were collected at 2 weeks, 4 weeks, 3 months, and 1 year and included visual analog scale pain, Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity, return to work/activity, range of motion, grip/pinch strength, and complications. RESULTS: Thirty-one patients (32 thumbs) were randomized from 51 patients offered participation over two years. One-year follow-up was 97%. Both groups had a decrease in visual analog scale pain scores at all postoperative time points. The trajectory of postoperative Patient-Reported Outcomes Measurement Information System Upper Extremity scores was similar, and both groups achieved the meaningful clinically important difference for improvement in PROMIS Upper Extremity by three months. Grip strength was substantially increased in both groups at one year. Return to work/activity and surgical complications favored the LRTI group. CONCLUSIONS: Our study did not suggest any clinically relevant differences in the postoperative patient-reported outcome measures or objective clinical measurements between LRTI and STS, although LRTI patients had a faster return to work/activity and lower complication rates. TYPE OF STUDY/LEVEL OF EVIDENCE: Prospective randomized clinical trial, level IIB clinical.
RESUMEN
Purpose: Combined trapeziectomy and suture-button suspensionplasty (SBS) is a common and well-established surgical treatment for thumb carpometacarpal (CMC) osteoarthritis. Although short and mid-term follow-up studies have shown promising outcomes with patients retaining excellent range of motion and strength, long-term data are lacking. The aim of our study was to assess the long-term outcomes of patients who underwent SBS surgery for thumb CMC arthritis, with a minimum follow-up period of 10 years. Methods: We evaluated 17 patients, at least 10 years after undergoing SBS surgery for thumb CMC arthritis. We measured grip and pinch strength, range of motion, and trapezial space height and compared it with the respective values measured on the routine postoperative 3-month follow-up visit. All patients have additionally completed the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire. Results: The study included 11 women and 6 men with an average age of 60.3 ± 6.4 years and a mean follow-up of 137.4 ± 11.4 months after surgery. The mean Quick Disabilities of the Arm, Shoulder, and Hand score was 9 (range: 0-40.9) at the long-term follow-up, compared with 26.2 (range: 4.5-75) recorded 3 months after the surgery. Grip and pinch strengths were 116% and 111% of the 3-month postoperative value, respectively. Radial abduction and palmar abduction were 98% and 94% of the 3-month postoperative value, respectively. Kapandji scores were either equal or higher than the previously documented scores. Average height of the trapezial space was 69% of the previous postoperative measurement. Conclusions: Our findings demonstrate that patients who underwent SBS surgery for thumb CMC osteoarthritis achieve excellent long-term outcomes by maintaining favorable subjective and objective results, despite some radiographic subsidence over time. These results indicate SBS to be an effective and durable technique for the long-term management of thumb CMC osteoarthritis. Type of study/level of evidence: Therapeutic IV.
RESUMEN
BACKGROUND: Trapeziometacarpal (TMC) osteoarthritis (OA) is a common cause of pain and weakness during thumb pinch leading to disability. There is no consensus about the best surgical treatment in unresponsive cases. The treatment is associated with costs and the recovery may take up to 1 year after surgery depending on the procedure. No randomized controlled trials have been conducted comparing ball and socket TMC prosthesis to trapeziectomy with ligament reconstruction. METHODS: A randomized, blinded, parallel-group superiority clinical trial comparing trapeziectomy with abductor pollicis longus (APL) arthroplasty and prosthetic replacement with Maïa® prosthesis. Patients, 18 years old and older, with a clinical diagnosis of unilateral or bilateral TMC OA who fulfill the trial's eligibility criteria will be invited to participate. The diagnosis will be made by experienced hand surgeons based on symptoms, clinical history, physical examination, and complementary imaging tests. A total of 106 patients who provide informed consent will be randomly assigned to treatment with APL arthroplasty and prosthetic replacement with Maïa® prosthesis. The participants will complete different questionnaires including EuroQuol 5D-5L (EQ-5D-5L), the Quick DASH, and the Patient Rated Wrist Evaluation (PRWE) at baseline, at 6 weeks, and 3, 6, 12, 24, 36, 48, and 60 months after surgical treatment. The participants will undergo physical examination, range of motion assessment, and strength measure every appointment. The trial's primary outcome variable is the change in the visual analog scale (VAS) from baseline to 12 months. A long-term follow-up analysis will be performed every year for 5 years to assess chronic changes and prosthesis survival rate. The costs will be calculated from the provider's and society perspective using direct and indirect medical costs. DISCUSSION: This is the first randomized study that investigates the effectiveness and cost-utility of trapeziectomy and ligament reconstruction arthroplasty and Maïa prosthesis. We expect the findings from this trial to lead to new insights into the surgical approach to TMC OA. TRIAL REGISTRATION: ClinicalTrials.gov NCT04562753. Registered on June 15, 2020.

Trapeziometacarpal joint osteoarthritis (TMJO) affects up to 33% of postmenopausal women, leading to pain, reduced mobility, and grip strength, with initial treatments focusing on non-surgical options like injections, orthoses, and exercises before considering surgery. A major challenge in managing TMJO involves selecting the optimal surgical strategy that is customized to individual clinical conditions. This study aimed to compare the effectiveness of three common surgical interventions for TMJO in relieving pain, including arthroscopic debridement (AD), trapeziectomy (TRAP), and joint replacement (JR). PubMed, Cochrane, Embase, and MEDLINE databases were queried according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for studies that presented pain outcomes following intervention for TMJO. Pain scores were reported preoperatively and postoperatively using the visual analog scale (VAS). Inclusion criteria included studies published in Q1 and Q2 journals and those with a follow-up of > six months. The final selection comprised 18 studies with 763 patients treated with AD (n = 102, 13%), TRAP (n = 428, 56%), and JR (n = 233, 31%) between 2010 and 2023, with a mean follow-up period of 38 ± 28 months. The studies included a total of 24 groups, five of which received AD, 13 of which received TRAP, and six of which received JR. The mean preoperative VAS was 6.7 ± 1.7, and the mean postoperative VAS was 1.7 ± 1.3 for all groups (P < 0.001). The meta-analysis demonstrated a mean preoperative pain score of 5.8 (95% CI, 4.1-7.5) for AD, 6.6 (95% CI, 5.7-7.5) for TRAP, and 7.8 (95% CI, 7.0-8.7) for JR. Postoperatively, there was a mean pain score of 2.2 (95% CI, 0.1-4.2) for AD, 1.4 (95% CI, 1.1-1.7) for TRAP, and 0.9 (95% CI, 0.6-1.2) for JR. This study showed that, if appropriately indicated, joint preservation with AD may be as effective as TRAP and JR for reducing pain associated with TMJO in the short term. However, the rate of conversion or revision should be assessed in future studies.
RESUMEN
Pain after trapeziectomy is a vexing problem, most commonly due to scaphometacarpal impingement. A number of treatment strategies have been described and are examined in this systematic review. In total, 27 studies describing revision surgery for unsatisfactory results after trapeziectomy were included. Results after soft tissue or synthetic suspensionplasties, arthrodesis procedures, implant arthroplasty and costochondral autografting were included. Most studies were heterogeneous in terms of patient selection and procedure performed, and the level of evidence and methodological quality were uniformly low. Autologous suspensionplasty procedures are the best studied and most rigorously reported techniques, with modest improvements in pain widely reported. Newer techniques using synthetic suture button suspension are encouraging with the benefit of earlier mobilization but require further study. Due to high incidences of complication and revision, the literature does not support the use of implant arthroplasty after trapeziectomy. Arthrodesis appears to be a reasonable last resort when attempts at suspension have failed.
RESUMEN
OBJECTIVE: Thumb osteoarthritis is a frequent pathology, mainly affecting the elderly. The surgical treatment initially described and having proved its worth is total trapeziectomy. Since the advent of trapeziometacarpal prostheses, several studies showed the non-inferiority of this technique on clinical criteria, with superiority in bone sparing, although neither technique demonstrated overall superiority. We therefore examined the specific complications of each surgical technique by analyzing their nature and prevalence through a review of the literature to compare them on these new parameters. METHODS: Seventy-four of the 320 articles reviewed were included, 38 of which concerned trapeziectomy, and 36 concerned prostheses, for a total of 4,865 patients. They were original studies, involving adults undergoing trapeziometacarpal arthroplasty or trapeziectomy, published after 2015, reporting at least one well-described complication. RESULTS: 6.13% of trapeziectomies presented severe complications (in particular thumb collapse and metacarpophalangeal hyperextension), 3.31% moderate complications and 1.90% minor complications, leading to a 2.0% revision rate. 23.88% of prostheses had severe complications (loosening, dislocation and wear), 5.06% moderate complications and 1.36% minor complications, leading to a 12.8% revision rate. In addition, we analyzed more recent prosthesis designs separately, and found lower prevalence of severe complications (16.56%) and revision surgery (4.3%). CONCLUSION: Revision surgery for trapeziometacarpal prostheses is usually only a standard trapeziectomy with the same follow-up as first-line trapeziectomy, whereas revision surgery for trapeziectomies is much more complex and the results are uncertain. For this reason, we would reserve total trapeziectomy for revision surgeries and patients with low functional demand for whom a second surgery is not desirable. Further studies could confirm this attitude, especially focusing on the latest generation of dual mobility implants.

The management of complications after surgery for basal thumb arthritis is sometimes challenging, and there are no clear recommendations on how to evaluate and manage patients with residual symptoms. The aim of the present article was to review the most common complications after surgery for basal thumb arthritis, with an emphasis on resection arthroplasty, joint replacement and joint fusion. In addition, possible management strategies for the different types of complications will be highlighted.

We compared the effects of capsule resection versus capsule suturing in patients treated with a dual-mobility trapeziometacarpal joint prosthesis. We included 131 patients with capsular resection and 57 patients with repair. The mean scores for pain and the brief Michigan Hand Outcomes Questionnaire were similar between the groups preoperatively and at 6 weeks and 1 year postoperatively. Mean key pinch strength was also similar in both groups before surgery and at 1 year, but higher in the capsular resection than in the suture group at 6 weeks. The incidence of complications reported throughout the 1-year postoperative period was not significantly different between the groups. One implant in the capsular resection group was revised for reasons most likely unrelated to capsule management. We conclude that the capsule can be safely resected during trapeziometacarpal joint implant arthroplasty.Level of evidence: III.
RESUMEN
Introduction: The aim of this prospective and randomized study is to analyze and compare the outcomes of two surgical techniques for trapeziometacarpal joint osteoarthritis (Eaton-Littler grade III and IV). Materials and methods: 52 consecutive patients underwent surgical intervention by two different surgical techniques and checked for subjective outcomes (DASH, NPRS), objective outcomes (ROM, opposition test, grinding test, pulp pinch, hand grip) and radiographic outcomes. Surgical time was calculated. Results: 26 patients underwent suspension arthroplasty using abductor pollicis longus tendon interposition (Ceruso procedure) and 26 patients underwent arthroplasty using suspension tenoplasty of the flexor radialis carpi (Altissimi procedure). Both techniques were performed by a single surgeon and showed good and satisfactory results, with best outcome reported in Altissimi procedure regarding DASH and ROM (p = 0.011 and p = 0.012, respectively), with reduced surgical time (about 6 min less, p = 0.03). The proximal shift between scaphoid and the base of first metacarpal did not influence the final results of the cases treated. Conclusion: This study provides evidence that trapeziectomy in combination with both tendon suspension arthroplasty and tendon interposition are two surgical procedures useful to solve advanced basal joint arthritis. Patients who underwent suspension tenoplasty without tendon interposition seemed to be generally more satisfied with significantly better symptomatic and functional outcomes.
RESUMEN
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. LEVEL OF EVIDENCE: III.

INTRODUCTION: Non-dissociative carpal instability (CIND) may lead to severe functional impairment. Destabilisation of the scapho-trapezial-trapezoidal (STT) ligament complex seems to result in a CIND. MATERIALS AND METHODS: In one group with eight cadaver arms, distal scaphoid pole was resected with the adjacent ligaments. In the other eight cadavers, hemitrapeziectomy was performed followed by total trapeziectomy. CT scans were performed in different wrist positions, and the changed positions of the scaphoid, lunate and capitate were measured in comparison to non-operated wrists. RESULTS: Mainly in clenched fist position, dissociation between proximal and distal row can be determined after total trapeziectomy and resection of distal scaphoid pole. Capitate rotates dorsally up to 24°, the scaphoid up to 17° and the lunate up to 7° compared to the non-operated wrists. Resection of the distal scaphoid pole results in dorsal rotation of capitate and scaphoid of about 14° and the lunate 8°. Relative scapholunate and capitolunate angle increased significantly after total trapeziectomy, especially in clenched fist position. After scaphoid pole resection, significant SL and CL angles changes could be seen in almost every wrist position. CONCLUSION: Destabilisation of the STT ligament complex by total trapeziectomy or distal scaphoid pole resection results in dissociation of the proximal and distal carpal row without instability within the proximal or distal row, corresponding to a CIND. LEVEL OF EVIDENCE: III.

Purpose: Trapeziectomy with tendon reconstruction/suspensionplasty (TRS) is the most commonly performed surgical procedure in the United States for treatment of thumb carpometacarpal (CMC) osteoarthritis (OA). Trapeziectomy with suture tape suspensionplasty (STS) has been used recently at the study institution as an alternative surgical treatment option with perceived benefits of earlier return to function and reduced operative time. The purpose of this study was to compare patient outcomes following TRS versus STS for treatment of thumb CMC OA. Methods: All patients who underwent primary, isolated TRS or STS for treatment of thumb CMC OA between 1/1/2014 and 9/1/2020 were analyzed. We assessed demographics and preoperative and postoperative patient-rated outcome scores including Patient-reported outcomes measurement information system scores as well as pain outcomes, satisfaction, and appearance at a mean of 2.6 years after surgery (minimum 6 months). Time to return to work and activities was compared between groups. Bivariate statistics compared outcomes between groups. Results: Ninety-four patients were included in the final study cohort, of which 53 underwent TRS and 41 underwent STS. There were no differences in preoperative, postoperative, or final patient-rated outcome scores between groups. Patients reported high global and appearance satisfaction scores at final follow-up in both groups. Mean tourniquet time was 15 minutes (26%) shorter and return to work was on average 3 weeks faster for the STS group. Conclusions: There were no differences in postoperative patient-rated outcome scores between the STS and TRS groups. The STS group had a shorter surgical time and faster return-to-work after surgery. Type of study/level of evidence: Therapeutic III.
RESUMEN
PURPOSE: Wrist and thumb pathology can coexist leading to potential indications for proximal row carpectomy (PRC) and trapeziectomy. In this setting, the axial stability of the first ray is not known. We sought to evaluate axial subsidence of the first metacarpal in cadavers following trapeziectomy and trapeziectomy with PRC to determine the mechanical effects of the procedures performed concurrently. METHODS: Eleven fresh-frozen cadaveric distal forearm specimens were used in this study. The specimens were fixed in cement and mounted to a material test system frame. A predetermined force (20 N) was applied to the thumb metacarpal to simulate forces observed with lateral pinch. Axial displacement of the thumb metacarpal was measured. The application of force was repeated following trapeziectomy on each hand and then again following PRC. Analysis was performed to compare thumb metacarpal subsidence of the 3 groups: native, trapeziectomy, and trapeziectomy with PRC. RESULTS: Before trapeziectomy, native cadaver specimens had an average of 5.1 ± 1.9 mm of thumb metacarpal subsidence under the material test system load (20 N), compared to 16.2 ± 3.4 mm following trapeziectomy, and 25.0 ± 5.5 mm for trapeziectomy with PRC. CONCLUSION: We observed a significant increase in thumb metacarpal subsidence following concurrent trapeziectomy with PRC when compared to trapeziectomy alone. Our results suggest that performing both operations together would lead to a substantial risk of first ray subsidence. CLINICAL RELEVANCE: When treating concurrent basilar thumb and wrist arthritis, it may be more effective to stage the procedures or use a form of thumb metacarpal suspension or arthrodesis.
RESUMEN
We compared the short-term recovery of patients treated with trapeziometacarpal joint (TMJ) implant arthroplasty versus resection-suspension-interposition (RSI) arthroplasty. Implant patients (n = 147) had a better 3-month postoperative brief Michigan Hand Outcomes Questionnaire (MHQ) score (mean 82) compared to RSI patients (n = 127), who had a mean score of 69. Key pinch strength at 3 months was also higher in the implant group compared to the RSI group (6.8 kg vs. 3.1 kg). At 1 year, both groups had similar brief MHQ scores, but key pinch remained higher in the implant group (7.0 kg vs. 3.9 kg [RSI]). After implant arthroplasty, employed patients returned to work after a mean of 44 days, which was significantly faster than the 84 days for RSI patients. Patients after TMJ implant arthroplasty recover significantly faster in the first 3 postoperative months compared to RSI patients. However, 1-year postoperative outcomes are similar for both cohorts, with key pinch strength remaining higher for patients with TMJ implant arthroplasty.Level of evidence: II.

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.

The aim of the present cadaveric study was to assess resistance to first metacarpal subsidence of three techniques of suspensionplasty after trapeziectomy. In total, 18 forearms (mean age 60 years [range 20-89]) were used with six specimens per surgical technique: palmar oblique ligament reconstruction with tendon interposition (LRTI), abductor pollicis longus (APL) suspensionplasty, or suture suspensionplasty. There was no significant difference in mean trapezial space height after trapeziectomy and suspensionplasty compared to the preoperative trapezial height. However, after simulation of physiological lateral pinch, there was a significant (p < 0.05) difference in mean trapezial space height between the APL suspensionplasty and the suture suspensionplasty compared to the LRTI group. After axial loading, there was significantly greater metacarpal subsidence in the LRTI group compared to the APL and suture suspensionplasty groups but no statistically significant difference between the suture suspensionplasty and the APL suspensionplasty groups.Level of evidence: V.
