Proximal femoral nail (PFN) and dynamic hip screw (DHS) are widely used for the management of intertrochanteric femur fractures (ITFs). Proximal femoral nailing offers biomechanical advantages but may cause iatrogenic displacement during the insertion.</p> <p><bold>The aim of the study</bold><bold> </bold>— to compare the degree of fracture displacement, specifically femoral shaft lateralization and neck-shaft angle changes, following dynamic hip screw and proximal femoral nail fixation in minimally displaced or non-displaced intertrochanteric femur fractures.</p> <p><bold>Methods</bold><bold>.</bold> A prospective cohort study was conducted on 40 patients with AO 31A1 ITFs from January to June 2024. Patients were divided into two groups: DHS (n = 20); PFN (n = 20). Radiological outcomes including postoperative neck-shaft angle and femoral shaft lateralization were measured on both injured and non-injured sides.</p> <p><bold>Results</bold><bold>.</bold> In the PFN group, the mean postoperative neck-shaft angle (131.30±4.54°) showed a varus change compared to the intact side (134.70±3.77°), but the difference was not statistically significant (p = 0.109). In the DHS group, there was no significant difference (p = 0.827). Femoral shaft lateralization on the injured side was significantly higher in the PFN group (56.60±7.07 mm) than in the DHS group (49.50 ± 6.59 mm; p = 0.002). No significant difference was found on the non-injured side (p = 0.261).</p> <p><bold>Conclusion</bold><bold>.</bold> Both PFN and DHS yield comparable neck-shaft angle outcomes in minimally displaced ITFs. However, PFN is associated with greater lateralization of the femoral shaft, which may reflect iatrogenic displacement during fixation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Проксимальный бедренный стержень (PFN, proximal femoral nail) и динамический бедренный винт (DHS, dynamic hip screw) широко используются в лечении чрезвертельных переломов бедренной кости. PFN обладает биомеханическими преимуществами, но может вызвать ятрогенное смещение во время установки.</p> <p><bold>Цель исследования</bold> — сравнить степень смещения отломков, в частности латерализацию бедренного отломка и величину шеечно-диафизарного угла, при фиксации динамическим бедренным винтом и проксимальным бедренным стержнем у пациентов с чрезвертельными переломами бедренной кости без смещения или с минимальным смещением.</p> <p><bold>Материал и методы.</bold> В период с января по июнь 2024 г. было проведено проспективное когортное исследование с участием 40 пациентов с чрезвертельным переломом типа 31A1 по AO/OTA. Пациенты были разделены на две группы (PFN, n = 20; DHS, n = 20). Рентгенологические результаты, включая послеоперационный шеечно-диафизарный угол (ШДУ) и латерализацию бедренного отломка, оценивались как с поврежденной, так и с неповрежденной стороны.</p> <p><bold>Результаты. </bold>В группе PFN средний послеоперационный ШДУ (131,30±4,54°) показал варусное изменение по сравнению с интактной стороной (134,70±3,77°), но разница не была статистически значимой (р = 0,109). В группе DHS значимой разницы выявлено не было (р = 0,827). Латерализация бедренного отломка на поврежденной стороне была статистически значимо выше в группе PFN (56,60±7,07 мм), чем в группе DHS (49,50±6,59 мм; р = 0,002). На неповрежденной стороне статистически значимой разницы обнаружено не было (р = 0,261).</p> <p><bold>Заключение.</bold> Как проксимальный бедренный стержень, так и динамический бедренный винт дают сопоставимую величину шеечно-диафизарного угла у пациентов с чрезвертельными переломами бедренной кости без смещения или с минимальным смещением. Однако проксимальный бедренный стержень ассоциируется с большей латерализацией бедренного отломка, что может вызывать ятрогенное смещение во время фиксации.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>proximal femoral nail</kwd><kwd>dynamic hip screw</kwd><kwd>intertrochanteric femur fractures</kwd><kwd>neck-shaft angle</kwd><kwd>non-displaced fracture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>проксимальный бедренный стержень</kwd><kwd>динамический бедренный винт</kwd><kwd>чрезвертельный перелом бедренной кости</kwd><kwd>шеечно-диафизарный угол</kwd><kwd>перелом без смещения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jonnes C., Sm S., Najimudeen S.
