An Updated Survey of Trends in the Surgical Management of Thumb Carpometacarpal Arthritis – The Increasing Popularity of the Suture Suspension Arthroplasty
Bibliographic record
Abstract
Background: The purpose of this study was to conduct an updated survey of American Society for Surgery of the Hand (ASSH) membership to evaluate current preferences for surgical management of thumb CMC arthritis. Past surveys have demonstrated LRTI to be the most preferred surgical technique. We hypothesised that current surgical preferences for thumb CMC arthritis have changed over the last several years due to rising popularity of high-strength suture implants. Methods: A 22-question survey inquired about the preferences for the surgical management of basal joint arthritis and was sent to the ASSH membership. Descriptive statistics were calculated on all survey questions. Chi-squared analysis was used to compare differences in thumb CMC arthroplasty preferences across respondents. Results: A total of 1,499 responses were available for analysis, yielding a response rate of 29.9%. For surgical management of basal joint arthritis in the primary setting, the largest percentage of respondents preferred open trapeziectomy with suture suspension arthroplasty (39.2%); amongst them, over half (56%) used a high-strength suture implant. This was followed by open trapeziectomy with LRTI (38.3%). In the revision setting, most respondents preferred open trapeziectomy with suture suspension arthroplasty (53.5%), followed by LRTI (24.6%). In determining the choice of procedure, respondents felt some form of metacarpal suspension and implant cost to be more important factors than ligament reconstruction and interposition. A higher proportion of international members (16.2%) utilised implant arthroplasty than US/Canadian members (1.1%; p < 0.01). Conclusions: Past surveys have demonstrated LRTI to be the most preferred surgical technique. The current survey demonstrates open trapeziectomy and suture suspension arthroplasty, especially using high-strength suture implants, gaining popularity amongst surgeons, while open trapeziectomy and LRTI decreasing in preference. Suture suspension arthroplasty is now the preferred surgical technique in both the primary and revision setting. Level of Evidence: Level IV (Therapeutic)

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
