Background:
Fracture neck of femur in the young presents significant challenges with high rates of complications. Osteosynthesis of femoral neck fractures in young adults is treated by anatomical reduction, along with stable internal fixation with multiple cannulated cancellous screws, dynamic hip screws, or a femoral neck system to preserve the natural femoral head. The biplane double-supported screw fixation (BDSF) method has emerged as a novel technique proposing enhanced stability, supported by promising biomechanical and cadaveric studies. However, clinical evidence evaluating the effectiveness of the BDSF method remains limited. This study was aimed at assessing the functional and radiological outcomes of the BDSF method in treating fracture of the neck of femur in the young.
Methods:
This study is a prospective study involving 30 patients with a fractured neck of femur with a mean age of 45.43 years (range 18-55 years). All patients underwent the BDSF method for fixation and were followed up for 1 year. Radiological outcomes were assessed at 6 weeks, 3 months, 6 months, and 1 year to look for fracture union, non-union, avascular necrosis (AVN) in the femoral head, and arthritic changes. Functional outcomes were assessed using the modified Harris hip score.
Results:
The rate of fracture union with the BDSF method of fixation was 96.7%. Complications observed were avascular necrosis (AVN) in 6.7%, non-union in 3.3%, and varus collapse in 13.3% of cases. Functional outcomes, evaluated using the Harris hip score, showed 50.0% excellent, 30.0% good, and 20.0% poor results. The mean Harris hip score was 83.3 at 1-year follow-up.
Conclusion:
The BDSF method for fixation of fracture of the neck of femur provides a reliable, biplanar stability with an acceptable union rate. The BDSF method ensures early rehabilitation and good functional outcome in fracture of the neck of the femur in young patients by preserving the natural femoral head, indicating its potential as a viable treatment option, although further large-scale, long-term research is warranted.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
