Abstract

Objective: Describe the clinical and radiographic characteristics of the study group of patients, the results of treatment of distal femoral fractures with locking screws at Hanoi Medical University Hospital. Method: Cross-sectional description combined with retrospective and prospective study, 32 patients with distal femoral fractures were treated with locking screws at Hanoi Medical University Hospital from January 2022 to April 2025. Patients were classified according to AO fractures, the results of fracture reduction were evaluated according to the Larson and Bostman scale, the results of bone healing were evaluated according to the mRUST scale and functional recovery according to R. Sander. Results: There were 32 patients participating in the study with an average age of 57.4 ± 19.1 (from 18-93 years old), the age group over 60 was dominant with a rate of 62.5%, with a male/female ratio of 12/20. The most common cause of fractures was traffic accidents (59.4%), and the most common fracture classification was group A1 with 53.1%. Most patients underwent surgery within the first week (96.9%), of which surgery within 48 hours accounted for 28.1%. Patients had good recovery on both X-ray indicators and based on the Larson and Bostman scale. The wound healed at the beginning of 93.8% (30/32 patients). According to the mRUST scale, all 32 patients had bone healing at the time of follow-up examination after at least 6 months, there were no cases of non-union or pseudo-joint, 93.8% of patients had good and very good functional recovery results according to R. Sander. Conclusion: Distal femoral fractures are common in people over 60 years old and often after traffic accidents with high energy levels. Bone fusion surgery with locking screws and plates gave positive results, good restoration of anatomical morphology on X-ray according to Larson and Bostman scores and good bone healing results according to mRUST and functional recovery according to R. Sander.
