摘要Introduction: The spinal column is the most common site for skeletal metastasis. Surgical stabilisation with instrumentation is an established method for the treatment of spinal metastasis. The aim of this study is to investigate the incidence of symptomatic and asymptomatic implant failure in spinal metastasis surgery and identify potential risk factors.
Methods: This retrospective cohort study includes 88 patients who received surgical stabilisation with instrumentation for the treatment of spinal metastasis from 2007-2017 at a single institution. Their medical records and postoperative X-rays were reviewed for evidence of implant failure. Statistical analyses with logistic regression of nine potential risk factors for the development of implant failures was performed to identify potential contributing risk factor.
Results: Implant failure was identified in nine of 88 cases (10.2%) with two cases required implant removal: one case for a non-healing sore secondary to progressive kyphosis and the other case for a deep-seated wound infection involving the implants. One case required wound debridement due to superficial wound infection. The remaining 6 cases were asymptomatic. No case required implant revision. Logistic regression analyses showed patients who received radiotherapy either before or after surgery were less likely to develop implant failure.
Conclusion: Radiological implant failure after instrumented surgery for the treatment of spinal metastasis is common. However, symptomatic implant failure leading to revision surgery is uncommon. Our result suggests radiotherapy either before or after spinal surgery is not associated with development of implant failure.
