Posterior wall fractures of the acetabulum are the most common acetabular fracture pattern. Stable, congruous hips are amenable to nonoperative management, whereas any instability in the hip is an indication for operative management of the posterior wall fracture. Stability cannot adequately be predicted by static imaging alone. Therefore, the dynamic stress examination under anesthesia remains the gold standard in determining hip stability to guide treatment. This case-based video demonstrates a systematic technique for performing an examination under anesthesia and explains how to interpret the fluoroscopic imaging to differentiate stable and unstable hips.
髋臼后壁骨折是最常见的髋臼骨折类型。稳定、一致的髋关节适合非手术治疗,而髋关节的任何不稳定都是手术治疗后壁骨折的指征。单纯的静态影像学不能充分预测稳定性。因此,麻醉下动态应力检查仍然是确定髋关节稳定性以指导治疗的金标准。本病例视频演示了一种在麻醉下进行检查的系统技术,并解释了如何解释荧光透视成像以区分稳定和不稳定的髋关节。
