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

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.

A Prospective Clinical Trial Comparing Denervation With Suspension Arthroplasty for Treatment of Carpometacarpal Arthritis of the Thumb

PURPOSE

Trapeziectomy with suspensionplasty is the most popular treatment for thumb carpometacarpal arthritis. However, carpometacarpal denervation has recently shown promise as an alternative treatment option. This study was designed to compare functional outcomes, pain reduction, and quality of life between denervation and suspension arthroplasty in patients treated for thumb carpometacarpal osteoarthritis.

METHODS

We conducted a prospective clinical trial between June 2020 and December 2021. Preoperative and postoperative evaluations were conducted on patients, including the evaluation of functional outcomes via the Michigan Hand Outcomes Questionnaire, pain with the visual analog score, quality of life with the EuroQol-5D, and the evaluation of time to return to function. Outcomes and complications were compared between patients undergoing denervation versus arthroplasty.

RESULTS

Forty-eight patients were included in the study, 34 of whom underwent denervation and 14 underwent suspension arthroplasty of the thumb carpometacarpal joint. Patients in the denervation group were younger, with an average age of 59 years compared with 67 years in the arthroplasty group. All other patient characteristics were similar. Pain reduction, functional outcomes, and quality of life scores showed equal improvement in both groups. Denervation patients had a reduced time to return to function (3.3 weeks vs 4.5 months in the arthroplasty group).

CONCLUSIONS

Carpometacarpal denervation appears to provide similar short-term outcomes as suspension arthroplasty for the treatment of thumb carpometacarpal arthritis. Treatment with denervation may offer a quicker return to function. The long-term outcomes of denervation remain unknown.

Arthroscopy-assisted partial trapeziectomy combined with ligament reconstruction for thumb carpometacarpal joint osteoarthritis: A different technique

BACKGROUND

There is no consensus on the best surgery option for thumb carpometacarpal osteoarthritis (CMC OA). The traditional method has the risk of large trauma, obvious metacarpal subsidence, and decreased stability. The aim of this study is to introduce a different technique to restore the function and stability of the first carpal metacarpal joint with minimal trauma, rapid pain relief, reduced complications, and the clinical outcomes in the long-term follow-up was evaluated and statistically analyzed.

METHODS

This was a retrospective study of 10 patients with a mean age of 51.8 years. The surgery consisted of removing partial trapezium through arthroscopy, reconstructing the stability with flexor carpi radialis suspension and tendon interposition. The subjective assessment included visual analog scale (VAS) of pain, quick disabilities of the arm, shoulder, and hand (Quick-DASH) score, and patient satisfaction. The range of motion, grip strength, pinch strength, and radiographic assessment, which can reflect stability of the thumb, were objectively evaluated and statistically analyzed.

RESULTS

Ten patients were monitored at a mean follow-up of 6.8 years. The mean grip strength improved significantly from 16.64 to 22.57 kg after surgery. Pinch strength improved significantly from 3.72 to 5.71 kg on average. The Kapandji score improved significantly from 5.7 to 8.6 on average. 80% (8/10) of the patients were satisfied with this surgery. On objective indicators, the VAS score decreased significantly from 6.4 to 1.3 on average. The mean Quick-DASH score improved significantly from 6.1 to 28.9. Postoperative x-ray showed slight subsidence and dislocation of the first metacarpal in two patients and did not affect the function by measurement.

CONCLUSION

Arthroscopy-assisted partial trapezium resection combined with ligament reconstruction could be a workable and promising surgical technique in patients with thumb CMC OA. It can offer the advantages of minimizing surgical injury by preserving the first carpal metacarpal joint capsule to protect its stability, with a rapid pain relief, function improvement, and satisfactory results in patients' clinical measurements.

Revision Thumb Carpometacarpal Arthroplasty

Revision thumb carpometacarpal (CMC) arthroplasty alleviates persistent pain and instability after nonimplant or implant CMC arthroplasty. Metacarpal subsidence onto the scaphoid causing impingement, missed diagnosis such as scaphotrapezoid arthritis, and metacarpophalangeal hyperextension are common causes of failed CMC arthroplasty. Literature shows that revision CMC arthroplasty has satisfactory outcomes. Currently, the mantra of revision is to restore the metacarpal height and treat concomitant pathology, but no single operation is a universal solution. Revision CMC arthroplasty has a relatively high complication rate, lower patient satisfaction than primary CMC arthroplasty, and may result in the need for further operative intervention.

Trapeziectomy for basal thumb osteoarthritis does not increase the risk of developing wrist osteoarthritis in the long term

BACKGROUND

Symptomatic osteoarthritis of the basal joint of the thumb (trapeziometacarpal joint) is a common disabling condition mainly affecting women. It is frequently treated with complete removal of the trapezium with or without soft-tissue interposition. There is limited evidence about whether removal of the trapezium affects stability of the wrist joint and increases the risk of developing wrist osteoarthritis. The aim of this study was to evaluate the long-term prevalence of OA in wrists with previous trapeziectomy compared to wrists with intact trapezium.

METHODS

Patients treated with surgery for trapeziometacarpal osteoarthritis at one orthopedic department were invited 10-29 (mean 17) years postoperatively for bilateral radiographic examination. We included radiographs from 114 hands with trapeziectomy and 46 hands with intact trapezium; 38 patients had unilateral trapeziectomy and intact contralateral trapezium. The radiographs were blinded so that the intact trapezium or the trapezial space after trapeziectomy was not visible. The radiographs were then evaluated for radiocarpal/midcarpal osteoarthritis independently by two assessors using three different osteoarthritis grading systems, including the Kellgren-Lawrence classification. The patients rated their satisfaction with the function of each of their hands on a visual analog scale (VAS) from 0 to 100 (higher score better).

RESULTS

The prevalence of osteoarthritis ranged from 20 to 26%, mostly mild (Kellgren-Lawrence grade 1). The prevalence of osteoarthritis did not differ between wrists with previous trapeziectomy and those with intact trapezium, both in the whole cohort and in the subgroup of patients with unilateral trapeziectomy and intact contralateral trapezium. There was no significant difference in hand function VAS scores between hands with previous trapeziectomy and hands with intact trapezium in the whole cohort or in the subgroup.

CONCLUSIONS

Removal of the trapezium as treatment for basal thumb osteoarthritis does not increase the risk of developing wrist osteoarthritis in the long term.
