“…However, in the aspect of the biomechanics of fracture healing, Pauwels’ classification is of great value. [9,10] In Pauwels grade-1 femoral neck fracture, compression is predominant. However, in Pauwels grade 3, the shearing force dominates the microenvironment and is associated with a significant varus force, which usually results in fracture displacement and varus collapse.…”

“…Despite superior biomechanical properties and greater fracture stability with sliding hip screws in internal fixation of femoral neck fractures, use of 3 cannulated screw has been the most popular technique, as superior torsion stability, minimally-invasive insertion, and limited disruption of femoral head blood supply may be lead to better postoperative function [1, 2, 1416]. Greater screw spread, screw placement close to the cortex for cortical support, and parallel screw placement reflect screw placement accuracy, and are thought to achieve greater stability and decreased risk of nonunion of the fracture [1720].…”

“…Bhandari et al [1] queried 442 surgeons and found that 82.8% preferred cannulated screws for nondisplaced fractures, with a 17% preference for displaced fractures. Luttrell et al [2] surveyed 272 Orthopaedic Trauma Association members regarding treatment of high-angle “vertical” femoral neck fractures, and found that 43.1% preferred cannulated screws, with or without off-axis screw placement. Some thought that optimal biomechanical stability and minimally-invasive technique could be achieved if accuracy of optimal screw placement could be maintained.…”

“…13 The inverted triangle, with screws abutting the anterior, inferior and posterior cortices, is the most commonly utilized configuration for Pauwels I and II fractures and thus far has been the most biomechanically stable screw arrangement analyzed for these fractures. 14,15,16 It is also often used for fixation of Pauwels III fractures despite a paucity of biomechanical data.…”

“…14,15,16 It is also often used for fixation of Pauwels III fractures despite a paucity of biomechanical data. 13 While a configuration consisting of a horizontal screw orthogonal to the vertical fracture line has been proposed, little biomechanical data exists. 17 Nowotarski et al showed this construct, with an inferior off axis screw, had greater axial stiffness than CHS constructs and inverted triangle constructs.…”
