What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests two common surgeries for treating thumb arthritis, which causes pain and limits thumb joint movement. It compares trapezial excision (removal of a small wrist bone), with or without extra soft tissue work, to a newer method called suture button suspension (using a small button and thread to stabilize the thumb). The goal is to determine which surgery provides better long-term relief. Patients with thumb arthritis for at least six months, who haven't found relief from other treatments, might be suitable candidates. As an unphased trial, this study offers patients the chance to explore innovative surgical options that could enhance their quality of life.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that both surgical treatments for thumb arthritis in this trial are generally safe. Studies have found trapezial excision to be a dependable option. Patients usually experience little to no pain and have minimal difficulty using their thumb after surgery. Nearly 94% of these surgeries last about 10 years without needing another procedure.

Similarly, the suture button suspension arthroplasty (SBS) demonstrates good safety results. Patients who undergo this surgery often report excellent long-term benefits, with significant improvements in thumb movement and reduced pain over time.

Both treatments have strong safety records, with most patients handling them well and experiencing few major problems.¹ ² ³ ⁴ ⁵

Why are researchers excited about this trial?

Researchers are excited about these treatments for thumb arthritis because they offer innovative methods compared to traditional options like fusion or trapeziectomy. The trapezial excision with soft tissue interposition and/or ligament reconstruction allows surgeons to use tendons like the FCR or APL to customize the procedure based on the patient's needs, potentially improving joint stability and function. Meanwhile, the suture button suspension arthroplasty (SBS) uses a suture button system to stabilize the joint, which could offer a less invasive alternative with quicker recovery times. These techniques may provide more flexibility and better outcomes for patients than the standard procedures currently in use.

What evidence suggests that this trial's treatments could be effective for thumb arthritis?

This trial will compare two treatments for thumb arthritis. Research has shown that trapezial excision, with or without additional procedures like soft tissue interposition or ligament reconstruction, leads to better outcomes. This method is known for its good long-term results and manageable side effects.

The trial also includes suture button suspension arthroplasty (SBS) as a treatment option. Research on SBS shows promising results, with patients often experiencing excellent long-term benefits. This method effectively improves thumb function and reduces pain. Both treatments in this trial have proven effective for managing thumb arthritis, offering patients reliable surgical choices.¹ ² ³ ⁶ ⁷

Are You a Good Fit for This Trial?

This trial is for individuals over 50 with isolated thumb arthritis who haven't improved with non-surgical treatments. Participants must be able to consent, follow the study plan, and attend clinical visits. Those with advanced arthritis stages, previous CMC surgeries, other hand conditions, inflammatory diseases or unable to maintain follow-up are excluded.

What Are the Treatments Tested in This Trial?

Interventions

CMC Arthroplasty

Trial Overview The study compares two surgical methods for treating thumb arthritis: ligament reconstruction and tendon interposition (LRTI) versus suture button suspension arthroplasty (SBS). Patient outcomes will be evaluated at multiple time points up to one year post-surgery.

How Is the Trial Designed?

2Treatment groups

Experimental Treatment

Group I: Trapezial excision with or without soft tissue interposition and /or ligament reconstructionExperimental Treatment1 Intervention

The participating surgeon will perform their usual version of a trapeziectomy and thumb metacarpal using either FCR tendon or abductor hallucis longs (APL) tendon. Tendon interposition will be left to the surgeon's discretion.

Group II: Suture button suspension arthroplasty (SBS)Experimental Treatment1 Intervention

Dorso-radial incision, capsulotomy between extensor pollicis brevis (EPB) and APL protecting the radial artery. A second incision is made on dorsum of hand between the 2nd and 3rd MCs. A cannulated drill with suture passer is passed from base of 1st MC to mid 2nd MC. The TightropeTM is passed from 1st to second MC with one button on the base of the 1st MC. Trapeziectomy is then performed using a cruciate osteotomy and rongeurs. The thumb is adducted against index MC to avoid excessive tightening and the suture is tied over a second button on the 2nd MC. Closure of capsule with Vicryl. Closure of skin with running Prolene suture.

Published Research Related to This Trial

A 71-year-old woman with arthritis in her left thumb CMC joint was successfully treated with a vascularized pedicled third CMC joint transfer, which is a new surgical option.

The patient experienced no pain and maintained active use of her hand in daily life following the procedure, indicating the treatment's efficacy and potential benefits for similar cases.

New option for surgical treatment of the trapeziometacarpal osteoarthritis: a case report.Kodama, N., Takemura, Y., Imai, S., et al.[2020]

In a study of 6,432 patients who underwent carpometacarpal (CMC) arthroplasty, only 0.5% were readmitted and 0.4% required reoperation within 30 days, indicating that the procedure is generally safe with low short-term complication rates.

Key risk factors for 30-day readmission and reoperation included being 75 years or older, having a BMI of 40 kg/m2 or more, and having conditions like insulin-dependent diabetes and chronic obstructive pulmonary disease (COPD), which can help surgeons identify patients at higher risk for complications.

Readmission and Reoperation Following Carpometacarpal Arthroplasty.Ling, K., Fassler, R., Burgan, J., et al.[2023]

In a study of 11 patients who underwent thumb CMC hemiarthroplasty with the BioPro prosthesis, there was a significant reduction in pain from a median score of 8/10 preoperatively to 1/10 postoperatively, indicating high efficacy of the procedure.

The BioPro prosthesis allows for minimal bone resection and has a low risk of complications, with most patients reporting satisfaction and willingness to recommend the surgery, although one case required revision due to improper implant placement.
