Abstract

Abstract: BACKGROUND: Manual reduction with external fixation using small splint for stable distal radius fracture can achieve satisfactory results, but there is some blindness. Development of musculoskeletal ultrasound provides the possibility for ultrasound-assisted reduction of fractures, which improves the quality and successful rate of reduction.
OBJECTIVE: To evaluate the feasibility of high-frequency ultrasound-guided manual reduction combined with small splint fixation in the treatment of stable fractures of the distal radius.
METHODS: One hundred patients who were diagnosed with unilateral stable distal radius fracture at Zigong Fourth People’s Hospital from January 2020 to July 2020 were randomly divided into two groups (n=50 per group): an experimental group and a control group. Patients in the experimental group received high-frequency ultrasound-guided manual reduction and small splint fixation, and patients in the control group received the closed reduction and small splint fixation. Wrist function was evaluated by modified Green and O'Brien scoring systems, and radiological findings were evaluated by modified Sanniento scoring method. The initial reduction success rate, wrist function scores, and imaging scores were compared between the two groups during 12-month follow-up.
RESULTS AND CONCLUSION: The success rate of initial reduction in the experimental group was significantly better than that in the control group (P < 0.05). The excellent rate of imaging evaluation was 90.0% and 62.0% in the experimental group and the control group, respectively, immediately after reduction, and there was a significant difference between the two groups (P < 0.05). At 2 months after reduction, the excellent rate of imaging evaluation was 80.0% and 56.0% in the experimental group and the control group, respectively, and there was a significant difference between the two groups (P < 0.05). At 2 months after reduction, the excellent rate of wrist function evaluation was 10.0% and 8.0% in the experimental group and the control group, respectively, and there was no significant difference between the two groups. At 12 months after reduction, the excellent rate of wrist function evaluation was 90.0% and 66.0% in the experimental group and the control group, respectively, and there was a significant difference between the two groups (P < 0.05). All these findings indicate that the high-frequency ultrasound-guided manual reduction with small splint fixation can improve the reduction success rate and quality, and improve the wrist function in patients with stable fracture of the distal radius.
