目的:股骨粗隆间骨折(IFF)是最常见的创伤性疾病之一,但是由于植入失败和再次手术率,这种情况没有确定的治疗方法。股骨近端仿生钉(PFBN),这是一种新设计的头髓内钉,是我们团队开发的。这项研究的目的是评估PFBN在不稳定IFF患者中的临床和影像学结果。
方法:2020年10月至2021年8月,在河北医科大学第三医院接受PFBN治疗的12例不稳定型IFF(31-A2,3)患者。我们通过测量围手术期指标和术后并发症来评估该治疗的临床治疗效果。临床结果,特定的射线照相参数,收集并分析术后1年内的并发症.
结果:患者的平均年龄为72.4±16.1岁(男5例,女7例)。平均手术时间90.4±16.0min,31-A2骨折的手术时间(83.1±12.2min)短于31-A3骨折的手术时间(105.0±12.9min)(p<0.05)。失血量为175毫升(范围:50至500毫升),住院时间为10.0±1.9天。在3岁时评估预后评估,手术后6个月和12个月;对于这些时间点,Harris髋关节评分分别为69.6±4.1,77.8±3.8和82.6±4.6,Parker-Palmer评分为5.3(5.0,7.0),6.3(5.3,7.0),和7.8(7.0,8.0),分别。
结论:PFBN在治疗不稳定IFF(尤其是老年患者)方面显示出优势,并且具有稳定性和安全性。这种创新的方法可以为处理不稳定的IFF提供新的选择。
Intertrochanteric femoral fractures (IFF) are one of the most common traumatic conditions, but there are no established treatment methods for this condition due to implant failure and re-operation rates. The proximal femoral bionic nail (PFBN), which is a new design of the cephalomedullary nail, was developed by our team. The objective of this study was to assess the clinical and radiographic outcomes of PFBN in patients with unstable IFF.
From October 2020 to August 2021, 12 patients diagnosed with unstable IFF (31-A2, 3) were treated with PFBN at the Third Hospital of Hebei Medical University. We evaluated the clinical therapeutic effects of this treatment by measuring peri-operative indicators and post-operative complications. Clinical outcomes, specific radiographic parameters, and post-operative complications were collected and analyzed within the first post-operative year.
The average age of the patients was 72.4 ± 16.1 years (five males and seven females). The mean operation time was 90.4 ± 16.0 min, whereas the operation time of 31-A2 fractures (83.1 ± 12.2 min) was shorter than that of 31-A3 fractures (105.0 ± 12.9 min) (p < 0.05). The blood loss was 175 ml (range: 50 to 500 ml), and the length of hospitalization was 10.0 ± 1.9 days. The prognosis evaluation was assessed at three, six and 12 months after the operation; for these time points, the Harris hip scores were 69.6 ± 4.1, 77.8 ± 3.8, and 82.6 ± 4.6, respectively, and the Parker-Palmer scores were 5.3 (5.0, 7.0), 6.3 (5.3, 7.0), and 7.8 (7.0, 8.0), respectively.
PFBN has shown advantages in the treatment of unstable IFF (particularly in geriatric patients) and possesses both stability and safety. This innovative method may provide a new option for treating unstable IFFs.
