Schloemann D, Hammert WC, Liu S, et al. - This study was carried out to ascertain the patient- and/or disease-related factors associated with patients undergoing surgical treatment of thumb carpometacarpal (CMC) arthritis. Researchers conducted a retrospective cohort study examining a total of 1,994 patients with thumb CMC arthritis treated at 2 institutions between February 2015 and November 2018. They obtained patient demographic and clinical information from medical records to characterize treatment modalities before hand surgeon evaluation, mental and physical comorbidities, and Patient-Reported Outcomes Measurement Information System assessments. The results of this study demonstrated that pain and functional limitations associated with thumb CMC arthritis are influenced by mental health comorbidities, but these factors do not prognosticate surgical treatment. Instead, patients’ prior surgical experience and surgeon attitudes toward thumb CMC arthritis seem to have a strong influence on the odds of patients undergoing surgery for thumb CMC arthritis.
