Proximal phalanx injection for trigger finger: randomized controlled trial

40 patients, greater than 18 years of age, with primary trigger finger were randomized into one of two treatment groups to receive different steroid injection techniques to see the overall effectiveness of each. Patients in one group received injection through the conventional technique (over the metacarpal head), while those in the second group received an injection using the midproximal phalanx technique. Results showed that those who received an injection through the phalanx technique experienced significantly less pain immediately after injection, but had similar recurrence rates when compared to the conventional technique.
