Is intramedullary nailing of femoral diaphyseal fractures in the lateral decubitus position as safe and effective as on a traction table?

Abstract

Objectives: The aim of this study was to compare the radiological and clinical results of femoral diaphyseal fractures operated in the lateral decubitus position with those operated in the supine position on a traction table and to detail the perioperative surgical technique.

Patients and methods: Between October 2018 and January 2022, in this prospective, randomized, and single-blind comparative study, 75 patients diagnosed with adult femoral diaphyseal fractures to whom intramedullary nails were applied were operated in the lateral decubitus position without a traction table (Group 1, 37 patients) and in the supine position with a traction table (Group 2, 38 patients). Preoperative age, gender, fracture mechanism, fracture type, and surgical waiting times were determined. Perioperative anesthesia type, surgery preparation time, surgical time, number of fluoroscopy doses, amount of bleeding, and type of reduction were evaluated, and detailed observational descriptions of the surgical techniques were made. In the postoperative period, radiological evaluations were made with x-ray radiography and orthoroentgenogram, while in the clinical evaluation, hip-knee joint range of motion and rotational evaluation were made with the Craigs test. Follow-up periods were determined and complications noted.

Results: The average age was 32 in Group 1 and 28 in Group 2, the female/male ratio was 1:36 in Group 1 and 5:33 in Group 2, and the follow-up period was 18.2 months Group 1 and 21.7 months in Group 2. No significant difference was detected between the groups in terms of age, gender, fracture mechanism, fracture type, anesthesia type, surgical waiting time, and follow-up period (p > 0.05). Compared to Group 2, the shorter preparation time, surgical time, and number of fluoroscopy doses in Group 1 were found to be statistically significant (p < 0.05). The differences in the amount of bleeding and need for open reduction were not statistically significant between the groups (p > 0.05), and no statistical difference was found in joint range of motion and rotational evaluation in clinical evaluation in both groups (p > 0.05). There was no significant difference in terms of complications between groups.

Conclusions: We found the lateral decubitus method without a traction table to be a safe and effective alternative to the supine method with a traction table in terms of the radiological and clinical results and that it also has the advantages of shortening the surgical time, reducing radiation exposure.

Level of evidence: Level 1 prospective, randomized, single-blind controlled study.
