Abstract

We evaluated the success of treatment of unstable hip joints with the Fettweis plaster followed by MRI to detect potential treatment failures. A total of 132 ultrasound-detected unstable hips of type D, III, or IV according to Graf were treated with closed reduction and Fettweis plaster, followed by MRI. We examined 19 type D, 55 type III, and 58 type IV. Mean age at diagnosis was 84.5 days (SD: ± 55.4). Treatment period was 63.2 days (SD: ± 22.2). In 13 cases, the MRI showed a poor reduction. After repetition of this treatment, all 13 showed a concentric reduction. The use of MRI detects 9.8% of treatment failures. We recommend an MRI examination after each closed reduction to ensure the success of the therapy.

摘要

我们评估了使用费特魏斯石膏治疗不稳定髋关节的成功率，并通过磁共振成像（MRI）检测潜在的治疗失败情况。根据格拉夫分类法，共有132例经超声检测为D型、III型或IV型的不稳定髋关节接受了闭合复位和费特魏斯石膏治疗，随后进行了MRI检查。我们检查了19例D型、55例III型和58例IV型。诊断时的平均年龄为84.5天（标准差：±55.4）。治疗期为63.2天（标准差：±22.2）。13例患者的MRI显示复位不佳。重复该治疗后，所有13例均显示同心复位。MRI的使用可检测出9.8%的治疗失败情况。我们建议在每次闭合复位后进行MRI检查，以确保治疗成功。
