Introduction: Osteosynthesis of femoral neck fractures is related up to 46% rate of complications. The novel method of biplane double-supported screw fixation (BDSF; Filipov’s method) offers better stability using three medially diverging cannulated screws with two of them buttressed on the calcar. Biomechanically, the most effective component is the distal screw placed at steeper angle and supported on a large area along the distal and posterior cortex of the femoral neck following its spiral anterior curve. Thereby, BDSF achieves the strongest possible distal-posterior cortical support for the fixation construct, which allows for immediate full weight-bearing.Aim:The aim of this study was to evaluate the role of biplane double supported screw fixation method (BDSF) in intra capsular femoral neck fractures in the terms of functional and radiological outcome.Materials and Method :Subject of this study were 27 patients with displaced Garden III–IV femoral neck fractures treated with BDSF. Three 6.5-mm cannulated screws were laid in two medially diverging oblique planes. The distal and the middle screws were supported on the calcar. The distal screw had additional support on the posterior neck cortex.Results: The outcomes in 27 patients were analysed for minimum 6 months, maximum upto 18 months follow-up. Bone union occurred in 90% of the cases (24 patients). Rate of nonunion was 10%. Modified Harris hip score was 90.13 (range 10–100) conclusion: by providing additional cortical support the novel BDSF method enhance femoral neck fracture fixation strength. keywords BDSF, Biplane, Femoral neck fracture, Fixation, Osteosynthesis, Hip fractures.

Tibial eminence ( ACL ) avulsions fractures are very common in adults . There are different techniques to approach these fractures , open arthrotomy ) vs minimally invassive arthroscopic ). Open technique is associated with high post op morbidity due to extensive soft tissue dissection , thats why most surgeons now a days prefer arthroscopic technique to fix these fractures . Similarly there are multiple options to fix these fracture e.g Sutures , K-wires , Screws . All these devices have limitations in term of strong stable fixation . These limitations can be dealt with UHMW sutures like Fibre wires . In this study we will discuss most advanced Arthroscopic technique of fixing these fractures using Fibre wire ( diff.configurations e.g figure of 8 , rectangles etc.)
