Rationale: Vertebral augmentation has become the main treatment for osteoporotic vertebral fractures (VFs). In this article, we report a very rare case of vertebral collapse and polymethylmethacrylate (PMMA) breakage after vertebroplasty. We describe the clinical characteristics and revision surgery performed to remove the broken PMMA cement, maintain stability, and corrects the kyphotic deformity, and we analyze the possible causes. Patient concerns: A 72-year-old man who suffered back pain underwent first lumbar vertebra (L1) percutaneous vertebroplasty (PVP) due to osteoporosis and a vertebral fracture in May 2013. Postoperatively, the patient's back pain was markedly alleviated. Unfortunately, his lumbar back pain recurred in November 2015. Diagnoses: Plain radiographs showed collapse of the L1 vertebral body, breakage of the PMMA cement, and severe kyphosis at the thoracolumbar junction. Interventions: The posterior pedicle was internally fixed and an anterior artificial vertebral body implant was placed to maintain stability and correct the kyphotic deformity in a 2-step surgical procedure. Outcomes: The back pain was alleviated and the patient returned to daily life for more than two years. Lessons: This case demonstrates that PVP is not a simple minimally invasive surgery, and significant postsurgical care is necessary. The true cause of this rare phenomenon remains unclear, but the long-term use of steroids, new injuries, and poorly corrected kyphosis after PVP may play a role. Surgeons must be aware of the kinds of complications that may occur, including rare complications such as vertebral lysis.
BACKGROUND The most commonly ingested foreign body in Asians is fish bone. The vast majority of patients have obvious symptoms and can be timely diagnosed and treated. Cases of pyogenic cervical spondylitis and diskitis with retropharyngeal and epidural abscess resulting in incomplete quadriplegia due to foreign body ingestion have been rarely reported. The absence of pharyngeal or esophageal discomfort and negative computed tomography (CT) findings of fish bone have not been reported. We report the case of an elderly female patient with delayed cervical infection and incomplete quadriplegia who had a history of fish bone ingestion. CASE SUMMARY A 73-year-old woman presented with right neck pain and weakness of four limbs for a week, and had a history of fish bone ingestion and negative findings on laryngoscopic examination one month previously. She did not complain of any pharyngeal or esophageal discomfort. Cervical magnetic resonance imaging showed C4/C5 spondylitis and diskitis along with retropharyngeal and ventral epidural abscesses. No sign of fish bone was detected on lateral cervical radiography and CT scans . The muscle strength of the patient’s right lower limb receded to grade 1 and other limbs to grade 2 suddenly on the 10th day of hospitalization. Emergency surgery was performed to drain the abscess and decompress the spinal cord by removing the anterior inflammatory necrotic tissue. Simultaneously, flexible esophagogastroduodenoscopy was carried out and a hole in the posterior pharyngeal wall was found. The motor weakness of the right lower limb improved to grade 3 and the other limbs to grade 4 within 2 d postoperatively. CONCLUSION This rare case highlights the awareness of the posterior pharyngeal or esophageal wall perforation in patients with cervical pyogenic spondylitis along with a history of fish bone ingestion, even though local discomfort symptoms are absent and the radiological examinations are negative.
