Abstract
Background
The aim of this study is to evaluate comparative biomechanical fixation provided with the BDSF method with the conventional CC screw fixation for treatment of femoral neck fractures with three parallel cannulated screws.
Methods
This is a prospective cohort study. There were two teams of surgeons out of which one team operated the patients with BDSF technique and second with conventional CC screw fixation technique; thus, the patients were randomly distributed into two groups. Patients were included in the study as per the following inclusion and exclusion criteria.
Results
Union was achieved in 15 (83.33%) patients managed by conventional CC screw technique, while union was achieved in 11 (91.67%) patients managed by BDSF technique in the present study. The average Harris hip score in present study was 90 score in patients managed by BDSF technique, while the average Harris hip score in present study was 80 score in patients managed by BDSF technique.
Conclusion
Both BDSF and conventional CC screw fixation are good fixation methods for fracture neck of femur. But functional outcome and fracture union rates are better with BDSF Technique. Although, there are some minor problems noted in BDSF technique such as outer cortical fracture at the entry point of beam screw and opening up of anterior cortex of oblique fracture patterns. Thus, BDSF method provides reliable fixation in which early mobilization and partial weight bearing of the patient may be allowed.
