Abstract

Abstract:

Background

At present, the adjustable brace can meet the needs of the elbow joint auxiliary stabilization and early functional exercise after the intercondylar fracture of the humerus. However, the adjustable brace still has certain disadvantages, so our hospital has improved the adjustable elbow brace, developed a relatively small tension, more flexible adjustment of the tension braces, and applied it to the postoperative rehabilitation exercises of clinical intercondylar fracture patients. Objective To investigate the clinical effect of modified tension braces on postoperative functional rehabilitation in patients with intercondylar humerus fractures.

Methods

The data of 40 patients with intercondylar fractures of the humerus treated by incision reduction and internal fixation were retrospectively analyzed. The control group (21 cases) used ordinary fixed braces for functional exercises alone, and the observation group (19 cases) used modified tension braces for practical exercises. The elbow flexion, dorsal elbow elongation, forearm rotation, forearm rotation, and Mayo elbow function score at postoperative brace removal and final follow-up were compared between the two groups to assess the efficacy of improving tension braces.

Results

All patients were followed up after surgery, with an average follow-up of 13.79 months. Compared with the control group, the ranges of motion of the elbow joint were [ (104.47±12.37) ° vs. (88.85±8.10) °, P <0.001] when removing the brace after surgery was observed. The ranges of motion of the elbow joint were [ (140.31±16.87) ° vs. (135.66±12.86) °, P=0.331] , and the difference was not statistically significant. The mayo scores of the elbow joint [ (78.84±5.04) points vs. (73.80 ± 4.46) points, P=0.002] , and the difference was statistically significant. The ranges of flexion and extension of the elbow at the last follow-up were [ (107.52±12.30) °vs. (93.00±8.47) °, P<0.001] , and the difference was statistically significant. The elbow rotational ranges of motion were [ (141.42±17.02) °vs. (137.19±12.80) °, P=0.37] , and the difference was not statistically significant. The elbow Mayo scores were [ (80.15± 5.24) points vs. (74.95±4.18) points, P=0.001] , and the difference was statistically significant.

Conclusions

The use of modified tension braces after surgery can improve the flexion range of motion and elbow joint function in patients with intercondylar humerus fractures.
