Summary: This study analyzed the mechanical stability of different fixation constructs for basicervical fractures using finite element analysis. The results showed that the DHS + screw construct had the optimal load distribution, and the FNS implant was suitable for anatomically reduced fractures without comminution.

Summary: Vertical transcervical hip fractures in young patients, also known as Pauwels type III fractures, are typically high-energy fractures. Artificial femoral head replacement surgery is not commonly used for treating femoral neck fractures in these patients. The commonly used devices for fixation are multiple screws or a sliding hip screw. The size, location, and length of the screws are important parameters for the structural performance of internal fixation implants, and the optimal screw configuration needs to be investigated for clinical practice. This study compared the biomechanical stability of the standard inverted triangle configuration with various newly proposed x-crossed screw configurations. FEA simulations showed that using an x-crossed-right assembly provided biomechanical stability in terms of maximum von Mises stresses and maximum femoral head displacement, but did not entirely suffice the desired stability in terms of maximum relative neck fracture displacement. Therefore, using an x-crossed screw assembly can provide the needed biomechanical stability for treating femoral neck fractures.

Summary: This study evaluated the biomechanical performances of the self-lock compression anti-rotation blade (SCAB) combined with a cannulated screw for fixation of Pauwels type III femoral neck fractures (FNF) using finite element analysis. The results showed that SCAB-based internal fixation exhibited superior biomechanical performances compared to other fixation methods, with lower displacement of the femur, Von Mises stress of internal fixations, stress on fracture surfaces, and displacement of fracture fragments in the X and Z axis.

Summary: The study found that the pre-sliding technique using the FNS can improve the fixation stability of Pauwels type III femoral neck fractures, while the use of longer anti-rotation screws does not significantly affect fixation stability.

Summary: This study presents the definition and incidence of coronal shear fracture of the femoral neck (CSFF) and compares its clinical characteristics and outcomes with those of the basicervical fractures. The results show that patients with CSFF have similar reoperation rate and postoperative radiographic outcomes as those with basicervical fractures, while the 1-year mortality rate is higher for CSFF.

Summary: While postoperative malrotation in the subtrochanteric region is well-known, malrotation after osteosynthesis in proximal femoral fractures has not been extensively studied. This study validated a novel CT-based measurement technique to accurately assess displacement in basicervical femoral neck fractures.

Summary: This study compared the biomechanical characteristics of FNS and CSS+MP in the treatment of Pauwels III femoral neck fractures through simulation experiments. The results showed that CSS+MP and FNS had better initial stability compared to CSS, but MP experienced higher shear stress, increasing the risk of internal fixation failure.

Summary: Extracapsular hip fractures in the elderly are commonly treated with surgically inserting an intramedullary nail. There are two options available: single head screw systems and double screw systems. The use of double screw systems increases the risk of reoperation by 3.6 times compared to single screw systems. Further research in a wider multicenter study is encouraged.

Summary: This study compares the biomechanical stability of the newly invented femoral neck system and three inverted-triangle cannulated compression screws in treating non-anatomical reduction Pauwels type-III femoral neck fractures. The results show that the femoral neck system has weaker stability compared to the three inverted-triangle cannulated compression screws. Therefore, anatomical reduction or positive buttress should be recommended during fracture reduction in femoral neck fractures.

Summary: The survivability of the FNS was evaluated, and risk factors for implant failure were assessed. Results showed a 12% implant failure rate, with 12 failure events occurring during the follow-up period. Pauwels type III fractures and an increasing AP Parker ratio were identified as significant risk factors for implant failure. Age was the only risk factor for increased 1-year mortality rate.

Summary: This study conducted a systematic literature review and meta-analysis to compare the risk of post-operative complications associated with different intramedullary (IM) devices in the treatment of unstable AO OTA 31-A trochanteric fractures. The findings indicate that the use of INTERTAN IM nail can reduce the risk of revision/reoperation, implant failures, and hip and thigh pain in unstable fractures without compromising clinical and functional outcomes.

Summary: This study compared the surgical outcomes of dynamic hip screws (DHS) and cephalomedullary nailing (CMN) for basicervical femoral neck fracture (BFNF). The results showed no significant differences in fracture union time, cut-out rate, and reoperation rate between the two fixation methods. The choice of implant can be based on the surgeon's preference.
