The diagnosis and treatment in patients with a bipolar fracture–dislocation of the forearm: a retrospective study

Backgrounds This study aims to investigate the treatment and clinical effect of bipolar fracture-dislocation of the forearm. Methods From March 2011 to September 2021, patients with bipolar fracture-dislocation of the forearm admitted to XXX and XXX Hospital were retrospectively analyzed. The timing of rehabilitation depended on the joint stability after the operation. The forearm function was evaluated according to the Anderson forearm function score. Results A total of 40 patients who underwent surgical treatment were screened, but only 24 received a minimum of 6 months of follow-ups and were included in the study. Nineteen males and five females were enrolled in the study, with an age range of 18-65 years and an average of 40.4 years. With an average follow-up of 23.6 months (7-62 months), no case was related to functional malformations and infections. The average range of motion of flexion and extension at the elbow was 125.9[degrees] (98[degrees]-138[degrees]), the average range of motion of flexion and extension at the wrist was 144.2[degrees] (120[degrees]-156[degrees]), and the average range of motion of rotation at the forearm was 139.6[degrees] (88[degrees]-170[degrees]). The Anderson's forearm function score of the last follow-up presented: excellent in 16 cases, satisfactory in 6 cases, dissatisfactory in 1 and failure in 1. Conclusions Bipolar fracture-dislocation of the forearm always represents high-energy injuries, of which the treatment principle includes complete reduction in distal and proximal dislocations and rehabilitation training as early as possible. Intraoperative fracture fixation follows after a stable reduction in the dislocation. Keywords: Forearm injuries, Elbow dislocations, Fractures, Diagnosis, High-energy injury
