Abstract

Objective: The study aimed to evaluate the treatment results of 40 patients with isolated closed tibial shaft fractures (or associated fibula fractures) undergoing tibial fusion surgery using SIGN nails without opening the fracture (assisted by C-Arm) at Thanh Hoa Provincial General Hospital. Research design: Cross-sectional descriptive study. Selection criteria: Patients over 18 years old, with a simple closed tibial shaft fracture (or with a fibula fracture) due to trauma, without severe deformity in the knee or ankle joints (knee flexion over 90⁰), with enough information according to the form Researched medical records, postoperative follow-up period > 6 months. Research results: Through a study of 40 cases of tibial shaft fractures undergoing closed fusion surgery with SIGN nails at Thanh Hoa Provincial Hospital between January 2020 and April 2024, it was found that men accounted for the majority (62 ,50%); Most common age: 18 - 40 (65%) and traffic accident is the main cause (62.50%); The most common fracture location is the middle third (55%); Lesions according to AO classification: type A is the highest (80%), of which A3 accounts for 47.50%; type B accounts for 20%; There are no type C lesions. Results: +/ Soon results: all cases had immediate healing, no post-operative complications; Results of fracture reduction according to the standards of Larson and Bostman: very good accounts for 90%, good accounts for 10%, there are no average or poor cases. +/ Late results: Bone healing results according to the standards of JL Haas and JY De La Cafinière: very good 92.5%, good bone healing 7.5%. Normal knee movement accounts for 97.5%, flexion restriction < 20⁰ accounts for 2.5%. Scoliosis of limbs 5 – 10⁰ accounts for 5%. The functional recovery results were very good in 92.5% and good in 7.5%, with no average or poor cases. Conclusion: Bone fusion surgery method using SIGN nail without opening the fracture, assisted by C-Arm is an effective and safe treatment method for tibial shaft fractures in adults. Can be applied at provincial hospital facilities.
