Background:
The purpose of this study was to identify predictive factors of poor response to intra-flexoral sheath corticosteroid injection, as well as to identify factors associated with patients' decisions to undergo surgical treatment.
Methods:
Data from 112 patients who received steroid injection treatment for trigger finger were reviewed retrospectively. Logistic regression was used to assess the prognostic value of factors assumed to affect prognosis (age, sex, underlying disease, history of illness, presence of carpal tunnel syndrome, multiple digit involvement, and pre- and post-operative disability scores).
Results:
Multiple digits were affected in 42 patients. Associated and underlying conditions were carpal tunnel syndrome (n = 36), hypertension (n = 23), hyperlipidemia (n = 14), and history of malignant tumor (n = 10). Logistic regression analysis showed that multiple digit involvement and Froimson clinical severity score were factors significantly associated with surgical treatment after intra-flexoral sheath corticosteroid injection treatment. These two factors were also found to be associated with the patients' decisions to undergo surgical treatment.
Conclusions:
Although local corticosteroid injection is useful in most cases, providers need to counsel patients with multiple digit involvement and/or severe cases about the possibility of requiring additional surgical treatment.
