Protection Effect of Elbow Joint Airbag on Patients with Upper Limb Fractures: A Quasi-Randomized Controlled Trial.

Objective: Wound healing is delayed because of swelling after upper limb fracture, and the traditional rehabilitation device used in physical therapy cannot flexibly adjust the fixation. This study aims to evaluate the effect of the designed elbow joint airbag protection device used in patients with upper arm fractures.

Methods: This is a quasi-randomized controlled trial. From November 2022 to March 2023, 70 hospitalized patients with unilateral upper arm fractures were recruited from a general tertiary hospital in eastern China. The patients were divided into an experimental group and a control group according to the random number table at 1:1. Among them, 35 patients who received elbow joint airbag protection for post-traumatic limb swelling were assigned to the experimental group, and the other 35 patients were assigned to the control group. The degree of swelling regression, a score of resting pain, and patient comfort level was compared between the two groups.

Results: The waiting time from swelling to allowing for surgery and pain score at rest were significantly lower in the experimental group than in the control group (P < .05 and P < .001 respectively). The comfort score of the experimental group was higher than that of the control group (P < .05), and these differences were statistically significant.

Conclusions: The elbow joint airbag protection can significantly reduce the waiting time for surgery, lessen the degree of swelling regression, reduce the pain in patients' hands caused by swelling, and significantly improve the comfort level. Hence, it is worth promoting in the clinical practice of orthopedic nursing.
