“…Additionally, there were no reported cases of implant breakage. In other studies, the overall mortality rate was 6.3%, with non-union and cut-out rates at 2.7%, while the need for revision surgery occurred in 2.5% of cases [49]. In this study, the cut-out occurrence rate was 7% in the GS group and 10.9% in the Affixus group.…”

Background: Intertrochanteric fractures are a global health concern, especially in aging populations like the Republic of Korea. Surgical treatments like intramedullary nailing are preferred for their benefit. Various hip nails are used worldwide, each with unique features and challenges. This study aims to compare the GS hip nail with the Affixus hip fracture nail for the treatment of intertrochanteric fractures. Material and Methods: This retrospective study, conducted at a single center, included 179 patients who underwent intramedullary nailing for intertrochanteric fractures using the GS hip nail or the Affixus hip fracture nail. Excluding specific cases, 43 patients in the GS group and 46 in the Affixus group met the minimum 6-month follow-up criteria. Result: The GS group exhibited a significantly shorter mean operation time (43.26 min) compared to the Affixus group (51.11 min). Radiographically, both groups showed no significant differences in their reduction quality, tip, and apex distance (TAD), or Cleveland index in the immediate postoperative window. However, the GS group achieved a greater valgus reduction based on the contralateral femoral neck shaft angle (NSA). At 6 months post-operation, there were no significant differences in TAD or advancement and sliding distances. Complication rates were similar between the two groups, with no implant breakages. Clinical outcomes, as measured via mHHS and EQ-5D-5L, showed no significant differences. Despite a slightly higher implant cost, the GS group had a lower total hospital cost than the Affixus group, but this was not statistically significant. Conclusions: This study highlights the efficiency of the GS hip nail in reducing the operation time compared to the Affixus hip fracture nail with comparable radiologic and clinical outcomes. Further research with long-term follow-up and larger patient studies are needed to fully assess its effectiveness in improving patient outcomes in hip fracture treatment.

“…The treatment of choice is intramedullary nailing [4] , even though in the literature there is no consensus on which is the best intramedullary device for lateral femoral fractures [5-6-7] . The purpose of this study is to assess the medium-term clinical and radiographic results obtained through the use of three different cephalo-medullary nails: straight nail with a cephalic screw (Gamma © Stryker Mahwah USA [8][9] ), straight nail with cephalic screw and anti-rotational screw (Affixus © Depuy Orthopaedic Inc. Warsaw USA [10] ) and anatomical nail with a cephalic screw (ZNN © Zimmer Natural Nail Warsaw USA [11][12] ).…”

The purpose of this study is to compare the results obtained using three different systems of osteosynthesis, developed for the surgical treatment of fractures of the trochanteric region of the femur, based on the principle intramedullary nailing: the Gamma nail, the Affixus nail and the ZNN nail. This is a retrospective study: 72 trochanteric fractures treated with the Gamma nail, 68 treated with the Affixus nail and 69 treated with the ZNN nail, between the years 2012 and 2014, with the prerequisite of a minimum follow-up of 18 months. The fractures were classified according to the AO system; the most commonly reported subtype was the A2 fracture. Clinical and radiographic examinations were performed, both at hospital admission and post-operatively, at 1, 3, 6, 12 and 18 months. Of the 209 patients, 171 were women and 38 were men. The average age was 83.12 years old. All three systems guaranteed an early mobilization and ambulation in most of the patients. There were no significant differences in the use of the three nails in terms of recovery of previous functional capacity, or in terms of the time required for the fracture to heal. There were no advantages encountered with the use of one intramedullary nail over another and, in particular, when observing the complications and patient outcome, there were no statistically significant differences detected.

“…[18,19] However, internal xation failure still exists when using PFNA method, especially in unstable fracture types with lateral wall fracture. [20,21] For unstable femoral intertrochanteric fractures with rupture lateral wall, especially type A3.3, scholars advocate reconstruction of the lateral wall in Stage I, and the use of nails, Kirschner wires, tension band, and plate to reconstruct the lateral wall according to different types of lateral wall fracture. It has a de nite effect on clinical treatments, but lacks data supporting of basic theoretical research.…”

Purpose: The biomechanical characteristics of Proximal Femoral Nail Antirotation (PFNA) and PFNA combined with Proximal Humerus Locking Plate (PHLP) in treatment of femoral intertrochanteric fracture with lateral wall fracture were compared by finite element analysis, and the biomechanical strength, stress and displacement distribution of the two internal fixation methods were compared. Methods: A healthy middle-aged female patient was selected. According to the femur CT scan data, the three-dimensional finite element models of the femur, PFNA, and PHLP were established .The simulated AO classification was 31-A3.3 femoral intertrochanteric fracture, and the two internal fixation assembly models of PFNA and PNFA+PHLP were established. The von mises stress distribution and displacement distribution nephograms of the two internal fixation models were observed when the same load was applied on the two models under the dynamic and static status. Result: Compared with PFNA fixation, PFNA+PHLP fixation reduced the maximum von mises stress by about 40%, while the maximum displacement changed little. The stress at the fracture end and the main nail position decreased, with a noticeablereduction of about 40% at the main nail. The Von Mises stress of the femoral head, femoral neck, medial, wall and spiral blade changed little. The total displacement of the femoral head, femoral neck, lateral wall, and spiral blade of PFNA+PHLP fixation decreased insignificant. Conclusion: PFNA + PHLP internal fixation in the treatment of femoral intertrochanteric fracture with lateral wall fracture has higher fixation strength and more reasonable stress distribution than PFNA internal fixation.
