The Effectiveness of a Noninvasive Shot Blocking Device in Reducing Pain of In-Office Injections in Hand Surgery

Abstract

MP joint blocking orthosis for sagittal band injury led to mostly satisfactory results, with 71% of patients achieving good to excellent outcomes. Manual labor, longer symptom duration, and grade III injury were associated with a higher likelihood of treatment failure. Table 87-1: Demographic and clinical characteristics of participants.
