the number of hip fractures is estimated to increase from 1.66 million in 1990 to 6.26 million by 2050. Internal fixation is the most common surgical treatment for intertrochanteric fractures.
the objective of the present research is to describe a minimally invasive technique with a modified instrument for the treatment of stable proximal femoral trochanteric fractures using the standard DHS, classified as Tronzo types 1 and 2 (AO 31A1.2), and presenting a case series.
a case was selected to present the technique. Patients operated by this technique undergo a clinical evaluation and preoperative preparation as routine. The criteria for inclusion in the study were the presence of stable fracture of the proximal femur verified by two hip specialist orthopedists, and operated by the minimally invasive technique with a modified instrument using a standard DHS. Exclusion criteria were cases of patients operated for unstable fractures, and the use of other surgical techniques. A case series of 98 patients was performed and discussed.
minimally invasive technique with a modified instrument using the standard DHS device can reduce bleeding, it decreases soft tissue injuries, surgical time, and hospital stay, as any other MIPO procedures. Ninety-eight patients underwent the operation (Tronzo types I and II), 59 female and 39 male, ages from 50 to 85 years old. Immediate post-operative complications were shortening of the lower limb, loss of fracture reduction, and death by clinical complications.
the present study describes a minimally invasive surgical technique using a modified instrument to perform proximal femoral osteosynthesis for stable trochanteric fractures, using the standard DHS.
预计髋部骨折的数量将从 1990 年的 166 万增加到 2050 年的 626 万。内固定是治疗股骨转子间骨折最常见的手术治疗方法。
本研究的目的是描述一种微创技术，使用改良的器械治疗使用标准 DHS 的稳定股骨转子间骨折，分类为 Tronzo 1 型和 2 型（AO 31A1.2），并呈现一系列病例。
选择了一个病例来介绍该技术。接受该技术治疗的患者接受临床评估和术前准备作为常规。纳入研究的标准为存在经两位髋关节专家骨科医生证实的稳定股骨近端骨折，以及采用改良器械使用标准 DHS 的微创技术进行手术。排除标准为不稳定骨折患者和使用其他手术技术的病例。进行了 98 例病例的病例系列研究并进行了讨论。
使用改良器械和标准 DHS 装置的微创技术可以减少出血，减少软组织损伤、手术时间和住院时间，与任何其他 MIPO 手术一样。98 例患者（Tronzo 1 型和 2 型）接受了手术，女性 59 例，男性 39 例，年龄 50 至 85 岁。术后即刻并发症包括下肢缩短、骨折复位丢失和因临床并发症死亡。
本研究描述了一种使用改良器械进行股骨近端骨折稳定型转子间骨折的微创手术技术，使用标准 DHS。
