Comparison of Two Different Percutaneous Screw Fixations for Treating Herbert B2‐Type Acute Scaphoid Fractures

Abstract

Objective Scaphoid fracture was the most common carpal fracture and the most challenging. The purpose of this study was to investigate and compare the clinical effects of closed reduction and percutaneous cannulated screw internal fixation under fluoroscopy and arthroscopy‐assisted percutaneous cannulated screw internal fixation in the treatment of Herbert B2‐type of acute scaphoid fractures. Methods A retrospective controlled study was conducted on 29 patients with Herbert B2‐type acute scaphoid fracture with a displacement of >1 mm admitted to our hospital from January 2017 to June 2021. Patients were divided into two groups, 11 patients were treated with closed reduction percutaneous cannulated screw internal fixation under fluoroscopy and 18 patients were treated with percutaneous cannulated screw internal fixation assisted by arthroscopy. The operative time, intraoperative fluoroscopy times, fracture healing time, complications, and postoperative wrist function score of the two groups were compared. Results All patients were followed up for 6–18 months (mean follow‐up duration: 10.38 ± 2.69 months). The respective operation times in the arthroscopy group and fluoroscopy group was 51.50 ± 6.69 min and 56.73 ± 11.48 min, respectively (p > 0.05). The number of fluoroscopies performed in the arthroscopy group was (6.83 ± 1.30), which was less than that in the fluoroscopy group (10.91 ± 2.62) (p 80 (80, 90) in the fluoroscopy group (z = 2.74, p 1 mm, the arthroscopy‐assisted percutaneous cannulated screw internal fixation has less fluoroscopy times, short fracture healing time, and good recovery effect of wrist function compared to the fluoroscopy.
