BACKGROUND: There is still a lack of global consensus on the optimum fixation construct for vertically-oriented displaced femoral neck fractures in young adults. The aim of this study was to assess the clinical outcomes of the combined cannulated screws and medial buttress plate as a fixation tool for Pauwels type III femoral neck fractures in adults.
METHODS: Twenty patients with the age of below 60 years had Pauwels type III femoral neck fractures and managed by open reduction and internal fixation using three cannulated screws and medial buttress plates. During the follow-up period, fracture union, femoral head avascular necrosis, fixation failure rate, infection and Modified Harris Hip Score (MHHS) were clinically and radiologically evaluated.
RESULTS: The average age of the patients was 47 years (range: 22-56 years). The minimum follow-up period was 12 months. Avascular necrosis and infection rates were 5%. Fixation failure was noticed in 2 cases (10%). Twelve months postoperatively, the average MHHS of 18 patients was 88.9 (standard deviation: 5.58).
CONCLUSIONS: In comparison to other traditional fixation methods, combined cannulated screws and medial buttress plate can be used safely for the Pauwels type III femoral neck fracture fixation in young adults with a satisfactory outcome.
