Conducted from April to September 2022, eligible participants over 18 years with ASA grades I or II were recruited.

Participants were randomly assigned to receive either memantine (20 mg daily preoperatively for three days and 10 mg daily postoperatively for two weeks) or a placebo.

While the hematoma block is widely used, circumferential block has been proposed as an alternative due to its broader analgesic coverage. However, direct comparative evidence remains limited.</p><p><strong>Methods: </strong>This double-blind randomized controlled trial (RCT) included 51 patients with distal radius fractures treated from June 2023 to May 2024. Patients were randomized into hematoma block or circumferential block groups. Pain levels were measured using the Visual Analog Scale (VAS) at four time points: before injection, 5 min post-injection, during reduction, and 10 min post-reduction. Radiographic alignment and complications were also assessed.</p><p><strong>Results: </strong>Baseline characteristics were comparable between groups (p = 0.42). Pain scores were significantly lower in the circumferential block group across all post-injection time points (p < 0.01). VAS scores: Circumferential block provided better pain relief at 5 min post-injection (1.19 vs. 3.08), during reduction (1.61 vs. 4.96), and 10 min post-reduction (1.50 vs. 4.12).

Its broader periosteal innervation coverage and ease of administration suggest it may be a valuable alternative for pain management in distal radius fracture reduction.
