Ceramic heads are widely used in modern total hip arthroplasty (THA). Although a rare complication, fractures of ceramic heads are described in the literature, evoking uncertainties regarding the in vivo stability of this material, especially when impaction of a fractured ceramic head can lead to disastrous results.
In this case report, we present a fracture of a ceramic head after trauma. A misinterpretation of the initial radiographs led to severe fragmentation of the ceramic head two weeks after the incident, later resulting in complete destruction of the arthroplasty.
Remarkably, radiographs obtained more than one year after the trauma led to this delayed diagnosis. A single radiographic evaluation, especially in patients with persistent pain after major trauma, with a ceramic head in a THA, seems to be insufficient.
陶瓷股骨头在现代全髋关节置换术(THA)中被广泛应用。尽管陶瓷股骨头骨折是一种罕见的并发症,但文献中对此有相关描述,这引发了人们对该材料体内稳定性的疑虑,尤其是当骨折的陶瓷股骨头受到撞击时可能会导致灾难性后果。
在本病例报告中,我们呈现了一例创伤后陶瓷股骨头骨折的情况。对初始X线片的误判导致伤后两周陶瓷股骨头严重碎裂,随后导致关节置换完全损坏。
值得注意的是,创伤一年多后所拍摄的X线片才得出这一延迟诊断。仅进行一次影像学评估,尤其是对于接受THA且陶瓷股骨头置换的患者在遭受重大创伤后仍持续疼痛的情况而言,似乎是不够的。
