Thumb Carpometacarpal Hemi-trapeziectomy: Creating a Balanced Arthroplasty

Background: Thumb carpometacarpal (CMC) joint arthritis is commonly encountered in Hand Surgery practice and can be quite disabling. Surgery is the best option for patients who have failed conservative management for thumb CMC arthritis. There are numerous surgical options to address thumb CMC arthritis with no clear advantage of one technique over the other. Methods: In this paper, we present our patient selection criteria and technique of hemi-trapeziectomy with interpositional arthroplasty for patients with thumb CMC arthritis. Conclusions: Hemi-trapeziectomy is ideal for patients with Eaton stage II/III thumb CMC arthritis in whom the STT joint is spared.

Suture suspension sling arthroplasty in thumb carpometacarpal joint arthritis: A case series.

Thumb carpometacarpal (CMC) joint arthritis is the most common condition in older adults and an upper-extremity surgical reconstruction site. Multiple treatments for CMC arthritis have been developed. Among them, suspension sling arthroplasty provides great results without requiring a tendon graft or advanced implants. However, it is rarely used in Indonesia. The modified suture suspension sling arthroplasty technique developed by Arnold Peter C Weiss was performed on three patients with CMC joint arthritis. In this procedure, after trapeziectomy, a nonabsorbable suture is performed to create a hammock between the abductor pollicis longus and flexor carpi radialis tendon to rest the thumb base metacarpal. The rehabilitation protocol was then continued, and the postoperative clinical condition was observed. Three weeks postoperatively, none of the three patients complained of pain. At 3months postoperatively, there were no signs of infection, and all patients continued the rehabilitation protocol. At 6months postoperatively, thumb range of motion was excellent, with no sign of infection and an increased DASH score of <5. Multiple treatments for CMC joint arthritis have been described in the literature but the indications and which treatment provides the best results were unclear. Among the various suspension sling methods, trapeziectomy is important for treating CMC joint arthritis. Suture suspension arthroplasty for treating thumb CMC joint arthritis achieved excellent clinical results and has several advantages, including shorter surgical time, no additional incision, reduced cost, no tendon harvesting, and implant fixation.

Selective Denervation for the Thumb Carpometacarpal Joint: Clinical Outcome and Comparison Based on Eaton Stage.

Various operative treatment options for advanced thumb carpometacarpal (CMC) joint arthritis have been presented without a definite surgical guideline. Selective denervation is a less invasive method for thumb CMC arthritis. However, it is unclear whether the clinical outcome varies with the stage of thumb CMC arthritis. This study aimed to evaluate the effectiveness of selective denervation on CMC arthritis for pain relief and functional outcome and to determine whether selective denervation depends on the stage of thumb CMC arthritis. We evaluated 29 thumbs of 28 patients with thumb CMC arthritis treated with selective denervation. The disease stage was determined with the classification system described by Eaton. The denervation was performed in the articular branches of the palmar cutaneous branch of the median nerve, lateral antebrachial cutaneous nerve, and superficial branch of radial nerve. The clinical outcomes were evaluated using the visual analog scale (VAS) and Disabilities of the Arm, Shoulder, and Hand (DASH) scores, along with evaluation of the improvement in both postoperative range of motion and strength recovery. The mean duration of follow-up was 24 months (range, 18-48 months). The average VAS and DASH scores decreased from 6.1 to 1.3 and from 54.3 to 24.1, respectively. The range of motion during palmar abduction and opposition of the metacarpophalangeal joint improved with an increase in mean value from 44.1 to 53.7 degrees, and the Kapandji score increased from 7.2 to 9.2, respectively. The grip and key pinch strengths increased from mean preoperative values of 14.3 and 3.1 kg to 27.1 and 6.2 kg, respectively, as measured at the 12-month follow-up. The rate of change in the VAS and DASH scores was significantly higher in stages I to III than in stage IV ( P = 0.01, P < 0.01, respectively). The selective denervation for thumb CMC arthritis was effective in pain relief and functional recovery with several advantages, including less invasive procedure, quick recovery time, and regaining of strength. The clinical outcomes were more effective in the early-stage group (Eaton stages I and II) compared with the advance-stage group (Eaton stages III and IV).

Cost-effectiveness of surgical treatment of thumb carpometacarpal joint arthritis: a value of information study

BackgroundThumb carpometacarpal (CMC) joint arthritis is one of the most prevalent arthritic conditions commonly treated with trapeziectomy alone or trapeziectomy with ligament reconstruction and tendon interposition (LRTI). We evaluate the cost-effectiveness and value of perfect and sample information of trapeziectomy alone, LRTI, and non-operative treatment.MethodsA societal perspective decision tree was modeled. To understand the value of future research in comparing quality-of-life after trapeziectomy, LRTI, and non-operative management we characterized uncertainty by fitting distributions to EQ-5D utility data published from the United Kingdom hand surgery registry. We used Monte Carlo simulation for the probabilistic sensitivity analysis and to evaluate the value of perfect and sample information.ResultsBoth trapeziectomy alone and LRTI were cost-effective compared to non-operative management ($2,540 and $3,511/QALY respectively). Trapeziectomy alone (base case total cost $8,251, QALY 14.08) was dominant compared to LRTI (base case total cost $8,798, QALY 13.34). However, probabilistic sensitivity analysis suggested there is a 12.5% chance LRTI may be preferred at a willingness-to-pay of $50,000/QALY. Sensitivity analysis revealed postoperative utilities are the most influential factors in determining cost-effectiveness. The value of perfect information was approximately $1,503/person. A study evaluating the quality-of-life of 1,000 patients in each arm undergoing trapeziectomy alone or LRTI could provide an expected $1,117 of information value. With approximately 40,000 CMC arthroplasties performed each year in the U.S., the annual value is close to $45 million.ConclusionsTrapeziectomy without LRTI appears to be the most cost-effective procedure in treating late-stage CMC arthritis and should be considered as first-line surgical treatment. There is substantial societal value in conducting additional research to better understand the relative quality-of-life improvements gained from these two common hand surgeries.

SIMPLE TRAPEZIECTOMY VERSUS TRAPEZIECTOMY WITH FLEXOR CARPI RADIALIS SUSPENSION: A 17-YEAR FOLLOW-UP OF A RANDOMIZED BLIND TRIAL

Thumb carpometacarpal joint (CMCJ) arthritis is a common and debilitating condition. The mainstay of surgical management is Trapeziectomy. Concerns about possible functional implications of collapse of the metacarpal into the arthroplasty space as well as the potential for scaphometacarpal led to the development of techniques to try and prevent this. 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 participated in our original trial, the 1 year findings of which were published in 2007. These 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. Patients were asked to complete a visual analogue scale (VAS) for satisfaction with the outcome of their procedure, rated on a scale from 0 (most dissatisfied) to 100 (most satisfied). They also completed the short version of the Disabilities of the Arm, Shoulder and Hand Score (QuickDASH) at their appointment. They underwent a functional assessment with a hand therapist and had a radiograph of the thumb.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 on radiograph. 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.

Physiotherapeutic Approaches in Thumb Carpometacarpal Joint Arthritis for Pain, Function, and Grip Strength

Abstract Thumb carpometacarpal joint osteoarthritis (CMC OA) is a common condition characterized by chronic progressive degeneration of the joint cartilage. Patients present with complaints of pain at the base of the thumb, morning stiffness, and muscle weakness, all of which impair hand function and thus interfere with activities and social participation. Grip and lateral pinch movements are most affected and have a direct impact on independence, self-care, and leisure activities. This review’s objective is to find physical therapy techniques for patients with thumb CMC OA’ and their effect on pain, function, grip strength, and quality of life. Databases searched were Google Scholar, PubMed, and ScienceDirect with keywords CMC arthritis, OA, function, and physiotherapy. Articles published in the last 5 years, in the English language, randomized controlled trials, controlled trials, prospective studies, or systemic reviews were included. Duplicate and nonrelevant articles, case reports, and noncontrolled trials were excluded. Thirteen articles were found of which five articles were included. Prefabricated CMC-metacarpophalangeal immobilization splint, proprioceptive exercises, and ischemic compression over myofascial trigger points in the first dorsal interossei, first dorsal interossei strengthening, and a self-management program called OA thumb-based therapy trial has shown an effect on pain, pinch strength, grip strength, and quality of life. Additional treatments can be used along with conservative treatment for better results in reducing pain, improving grip strength, function, and quality of life in patients with CMC joint arthritis. Utilizing these methods can enhance clinical practice interventions in the management of thumb CMC joint arthritis.

The effectiveness of Wharton’s jelly versus steroid injection for the treatment of thumb carpometacarpal joint arthritis for pain relief and the increase of function

We compared the effectiveness of Wharton’s jelly versus steroid injection into the carpometacarpophalangeal joint by comparing 60 patients in two cohorts with a follow up evaluation at three months and then at one year. We evaluated preoperative and postoperative grip strength, pinch strength, thumb range of motion, Disabilities of Arm, Shoulder, and Hand (DASH) score and a Visual Analog (VAS) pain score before the injection and then at 3 months and 12 months after injection. The patients in the steroid injection group had substantial improvement in their DASH and VAS pain scores as well as their pinch strength at 3 months p &lt; .05. However, by the 12-month evaluation the benefits of the steroid injection had completely dissipated. The patients in the Wharton’s jelly cohort had improvements at 3 months in terms DASH and VAS score and pinch strength and this improvement persisted at the one-year evaluation. However, grip strength and thumb range of motion did not substantially improve in either group

Flexor Carpi Radialis Tendon Insertion Onto the Trapezial Ridge: An Anatomic Description

The flexor carpi radialis (FCR) tendon is often involved in surgical procedures of the hand and wrist. The FCR tendon may be mobilized from the trapezium during distal radius fracture fixation, for tendon transfer, and during carpometacarpal joint procedures. There is a paucity of literature describing the anatomy of the FCR insertion onto the trapezial ridge. We analyzed the insertional characteristics of the FCR onto the trapezium. Forty-two fresh-frozen cadaveric wrists were dissected using the extended FCR approach through the FCR tendon sheath. The length of the fibrous portion of the FCR insertion onto the trapezial ridge was measured from proximal to distal using a digital caliper. FCR insertion onto the trapezium was present in all specimens. The mean length of the FCR insertion was 11.8 ± 4.14 mm. The character of the tissue quality varied across specimens. These results demonstrate the commonality of the FCR fibers that insert onto the trapezium. The length and tissue quality of this insertion varied across specimens. Understanding the complex anatomy of the hand and wrist facilitates surgical planning and intraoperative techniques. The FCR tendon insertion onto the trapezium is an important component of exposure for the volar approach to the distal radius and surgical management of thumb carpometacarpal joint arthritis.

Incorporation of occupational based intervention into joint protection education for individuals with thumb carpometacarpal osteoarthritis: A case series

BackgroundTo our knowledge, the use of occupational performance in education on joint protection techniques has not been studied for individuals with thumb carpometacarpal (CMC) osteoarthritis. PurposeThis case series was designed to investigate if occupation-based instruction inside the clinic was useful and found satisfactory as an educational tool for individuals with thumb CMC joint arthritis. MethodsThree participants with thumb CMC joint osteoarthritis performed washing, rinsing, and drying a dish, moving a pot and pan, maneuvering a laundry basket, and pouring from a pitcher during joint protection education in the therapy clinic with a skilled hand therapist in addition to routine treatment. Satisfaction with this intervention was assessed via a 3-question satisfaction survey. Pain with activity and function via the Thumb Disability Examination were assessed at baseline and a 4week follow up. ResultsPatients in this study expressed satisfaction with the inclusion of the performance of occupations in their joint protection education in the clinic. Pain with activity improved by an average of 1.7/10 on a 10-point Numeric Pain Rating Scale and function improved by an average of 10.04 on the Thumb Disability Examination. ConclusionsAlthough no causal relationships can be assumed in this study, hand therapists should consider adding occupation-based intervention as a component of patient education on joint protection for individuals with thumb CMC joint osteoarthritis.

Characterizing response to a dynamic stability modeled approach for thumb carpometacarpal joint pain: A retrospective study

Study DesignRetrospective case series. IntroductionLiterature trends indicate that thumb dynamic stabilization may benefit clients with thumb carpometacarpal (CMC) joint pain and arthritis. There is minimal research investigating whether client characteristics predict responsiveness to hand therapy for thumb dynamic stabilization. Purpose of the Study1) To investigate how adults with thumb CMC joint pain responded to a hand therapy dynamic stabilization modeled intervention. 2) To determine if various client factors influenced responsiveness and to what extent. MethodsAn electronic medical record search identified adults treated from August 2009 through December 2015 for thumb CMC joint pain. Radiographs were retrospectively staged. Outcome measures were 1) Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) total disability score and 2) Numerical Pain Rating Scale (NPRS). Paired t-tests were performed to compare pre and post treatment measures. Multivariate analyses were used to investigate predictive factors. ResultsA total of 249 charts were analyzed. Large overall significant effects were noted for disability score (QuickDASH P <.001, X = 12.1, Cohen's d = 0.9). The average improvement of 2.1 (SD = 2.6) points exceeded the minimal clinically important difference (MCID) of 1.7 points on the NPRS pain scale. Significant predictors of QuickDASH Scores were radiographic staging, bilateral hand involvement and initial pain ratings. Significant predictors for change in pain scores (meeting or exceeding the minimal clinically important difference for the NPRS) were bilateral thumb involvement and initial “pain at worst” rating. ConclusionAfter completing hand therapy with a dynamic stabilization approach, clients had less pain and disability. Those who had unilateral thumb pain, or those who started with higher pain levels were most likely to have clinically meaningful improvements in pain. Clients in early CMC osteoarthritis (OA) stages responded better than those in later stages, indicating that early referral to therapy is important.

Optimal Center of Rotation for Ball-And-Socket Thumb Carpometacarpal Arthroplasty Identified Using Three-Dimensional Kinematic Analysis: A Pilot Study.

Total joint arthroplasty is one of the surgical option for thumb carpometacarpal (CMC) joint arthritis, however the optimal position the center of rotation (COR) has not been quantified. The purpose of this study is to identify ideal ball-and-socket thumb carpometacarpal joint implants and the optimal position of the COR. We obtained eight right thumb computed tomography images each from ten healthy men, comprising four images each of thumbs at various angles of flexion-extension and abduction-adduction. We reconstructed 3D bone models on 3D CAD, created virtual ball-and-socket implants with three variables (neck offset, implant height, neck rotation), and found the optimal COR where the position change in the COR was smallest across various thumb positions. When the offset was 4.5 mm, neck rotation angle was 130.6° from the radial side to the palmar side of the first metacarpal, and implant height from the distal end of the metacarpal was 43.6 mm, we could restore almost normal kinematics. This study could serve as a reference for implant development and surgical technique guidelines.

Arthroscopic Management of Thumb Carpometacarpal Joint Arthritis and Pathology.

Basilar thumb arthritis is a debilitating condition characterized by pain, reduced joint stability, and reduced capacity for daily activities. Various arthroscopic approaches have been described based on patient factors, as well as radiographic and arthroscopic staging criteria. Here we provide an overview of arthroscopic management of basilar thumb arthritis, including patient evaluation, surgical techniques, outcomes, and new developments. We describe our preferred approach for Eaton stage I-III disease, consisting of arthroscopic hemitrapeziectomy with suture button suspensionplasty. This technique is safe, reliable, and allows for early range of motion and quicker recovery while minimizing scarring and reducing the risk of nerve injury.

Prognostic factors and clinical features in metacarpophalangeal joint hyperextension after ligament reconstruction with trapeziectomy: A retrospective cohort study

BackgroundManagement of metacarpophalangeal (MCP) hyperextension deformity in thumb carpometacarpal (CMC) joint arthritis is challenging. It remains unclear how the preoperative MCP joint angle affects the outcomes. The present study aimed to clarify the associations between postoperative MCP hyperextension deformity and outcomes, and to determine the preoperative MCP joint angle that can predict poor outcomes. MethodsWe investigated the functional outcomes of patients who underwent surgery for CMC arthritis at two institutions from 2016 to 2020. All patients received a modified Thompson technique, ligament reconstruction suspension arthroplasty, and had no additional treatment for MCP hyperextension. The patients were divided into three groups according to their postoperative MCP joint angles: Group A, <10°; Group B, 10°–20°; Group C, >20°. Evaluations included preoperative and postoperative VAS, Quick DASH, range of motion (ROM), grip power, pinch strength, first web space angle, and postoperative trapezial space ratio (TSR). ResultsOverall, 66 eligible patients (72 thumbs) were identified and received follow-up for a mean of 25.2 months. The 72 thumbs were assigned to Group A (n = 38), Group B (n = 16), and Group C (n = 18). Group C had significantly lower preoperative MCP joint angle and postoperative grip power, pinch strength, and TSR compared with the Group A (P < 0.05). However, there were no significant differences in VAS, Quick DASH, ROM, and first web space angle (P > 0.05). The preoperative risk factor for highly residual MCP hyperextension was preoperative MCP joint angle (OR = 1.078; P = 0.001), with a cut-off value of 21.5° (AUC = 0.79; sensitivity = 0.813; specificity = 0.821). ConclusionsPostoperative MCP hyperextension of >20° after ligament reconstruction with trapeziectomy has adverse effects on functional outcomes. In cases with preoperative MCP joint angle of >21.5°, additional treatment for MCP hyperextension should be considered.

A Meta-analysis of Surgical Interventions for Base of Thumb Arthritis.

Background There is a myriad of available surgical options for thumb carpometacarpal joint (CMCJ) arthritis and no robust evidence exists to guide the decisions of treating surgeons. Our aim was to assess the comparative effectiveness of different surgical interventions available for the treatment of thumb CMCJ arthritis. Methods We performed a systematic review, pairwise, and network meta-analysis of all randomized studies comparing surgical interventions for thumb CMCJ arthritis. Our primary outcomes were pain, function, and key pinch strength at long-term follow-up (> 6 months). Risk of bias and certainty of evidence were assessed for each outcome measure of compared interventions separately. Clinical recommendations were based on evidence of strong or moderate certainty. Results A total of 17 randomized studies were included in the systematic review. Where possible, pairwise and network meta-analyses were performed. Based on evidence of moderate certainty, trapeziectomy with a concomitant ligament reconstruction and tendon interposition (LRTI) does not appear to be associated with any long-term clinical benefits compared with simple trapeziectomy (function: mean difference [MD] -3.72 [-9.15, 1.71], p = 0.64 favoring simple trapeziectomy; key pinch strength: MD 0.07 kg [-0.28, 0.43], p = 0.68 favoring trapeziectomy with LRTI). Treatment rankings from the network meta-analysis favored trapeziectomy with and without LRTI, joint replacement, and arthrodesis. Trapeziectomy with LRTI appears to be associated with fewer major complications compared with joint replacement and arthrodesis, and more minor complications compared with simple trapeziectomy. Conclusion Until further high-quality research indicates otherwise, simple trapeziectomy should be the preferred surgical modality for base of the thumb arthritis. Level of Evidence This is a Level 1 study.

Effects of Magnetic Resonance Imaging With Axial Traction of the Thumb Carpometacarpal Joint on Articular Cartilage Visibility: A Feasibility Study.

ObjectivesThe objective of this study was to verify the usefulness of magnetic resonance imaging (MRI) with axial traction of the thumb for observing articular cartilage.Materials and methodsEleven healthy adult volunteers (39.7 ± 7.4 years) without thumb carpometacarpal joint arthritis or trauma were included in this study. A 3-tesla (3T) MRI (Magnetom Skyra, Siemens Healthineers AG, Munich, Germany) of the right thumb with axial traction applied by a finger trap with three traction weights (0, 2, and 5 kg) was performed. A 3D T2* multiecho data imaging combination (MEDIC) was selected to visualize the articular cartilage. After multiplanar reconstruction, sagittal and coronal images of the thumb carpometacarpal joint were used to evaluate the articular cartilage visibility and joint space widths at five locations. Articular cartilage visibility was evaluated using our original classification method that used the percentage of the cartilage detectable area. The Friedman test was used to compare the differences between each traction weight and location.ResultsArticular cartilage visibility significantly improved with axial traction. The average joint space widths with the 5-kg application were 1.9 ± 0.8, 3.9 ± 0.6, 2.0 ± 0.9, 3.9 ± 1.1, and 2.5 ± 1.4 mm at the center, volar edge, dorsal edge, radial edge, and ulnar edge, respectively. The joint space widths significantly increased proportionally with the traction weight at all locations. The joint space widths at the volar and radial edges were significantly greater than those at other locations.ConclusionApplying axial traction to the thumb increased the joint space widths and improved the visibility of the articular cartilage in the carpometacarpal joint on MRI.

The Efficacy of Intra-Articular Versus Extra-Articular Corticosteroid Injections in the Thumb Carpometacarpal Joint

PurposeThis study evaluated whether the location of steroid deposition (intra-articular vs extra-articular) for thumb carpometacarpal (CMC) joint arthritis affects clinical outcomes.MethodsWe prospectively enrolled 102 hands (82 patients) with thumb CMC joint arthritis. Patients received a CMC joint injection with Triamcinolone and radiopaque contrast. Wrist radiographs were used to visualize the injection location. Patients completed Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) questionnaires and visual analog scale (VAS; scale, 1–100) pain scores before injection and then at 1 week and 1, 3, and 6 months after injection. Generalized linear regression models were constructed to identify variables associated with clinical outcomes.ResultsThe rate of intra-articular injection was 80%. No differences were found between the 2 groups in preinjection DASH or VAS scores. After 1 week, both the intra-articular and extra-articular groups showed improvements of DASH (14.2 and 11.2, respectively) and VAS (15.5 and 15.0, respectively) scores. Although both groups were worse at 3 months, the intra-articular group had significantly lower DASH (26.7 vs 37.5, respectively) and VAS (26.5 vs 39.0, respectively) scores than the extra-articular group. There were no differences between the intra-articular and extra-articular groups for DASH (33.8 vs 42.5, respectively) or VAS scores at 6 months. The intra-articular group maintained significant improvements in outcomes for up to 6 months, while the extra-articular group only maintained them for up to 1 month. The Eaton-Littler classification was found to be a predictor of DASH and VAS scores at 3 and 6 months.ConclusionsIntra-articular injection in the thumb CMC joint provides significantly greater pain relief and functional improvement compared to extra-articular injection at 3 months. Inadvertent extra-articular injection is common and appears to provide short-term pain relief and functional improvement. Some patients receiving intra-articular injections continue experiencing relief for up to 6 months.Type of study/level of evidenceTherapeutic II.

Arthroscopic Partial Trapeziectomy for Thumb Carpometacarpal Joint Osteoarthritis: 5-Year Follow-up.

Osteoarthritis of the thumb carpometacarpal (CMC) joint is the most common type of arthritis of the hand. The goal of the study was to evaluate clinical results and radiographic changes after arthroscopic partial trapeziectomy combined with ligament shrinkage and K-wire fixation to treat thumb CMC joint arthritis. From February 2013 to March 2014, 24 patients with thumb CMC joint arthritis received this arthroscopic procedure. We investigated the preoperative and postoperative Modified Mayo Wrist Score (MMWS); Disabilities of the Arm, Shoulder and Hand (DASH) score; radiographic changes; and associated complications. Sixteen patients completed 5 years of functional score and radiographic follow-up. Comparison of preoperative and postoperative MMWS and DASH scores showed significant improvement after the arthroscopic procedure. Pre-operative and postoperative evaluation of radiographic changes showed significant differences in the CMC joint distance, scaphoid-metacarpal distance, trapezium-metacarpal distance, and metacarpal prominence distance. This arthroscopic procedure is an effective and less invasive method for the treatment of CMC joint arthritis. This procedure can improve clinical function, preserve the mechanical height of the trapezium, and increase CMC joint space. We report our surgical technique and some pitfalls that required attention during the arthroscopic procedure. [Orthopedics. 2022;45(3):e140-e147.].
