Oral extrusion of a screw after anterior cervical spine plating
Study Design:
A case report of a 76-year-old woman who retched up a screw from a cervical spine locking plate 5 years after anterior cervical spine fusion. The literature relevant to this topic is reviewed.
Objectives:
To report the rare but potentially life-threatening complication of oral screw extrusion after anterior cervical spine plating, to review the relevant literature on the topic, and to discuss the clinical management of instrumentation failure in anterior cervical spine plating.
Summary Of Background Data:
Anterior cervical spine fusion and stabilization is a well-established procedure. Complications include instrumentation failure, which can progress to extrusion through the gastrointestinal tract. Management is dependent on the severity and progression of clinical and radiologic signs and symptoms. Reoperation should be considered in certain cases.
Methods:
A rare complication of anterior cervical spine plating in a 76-year-old woman 5 years after the initial operation is reported. The patient was assessed with serial physical examination and radiograph and one further follow-up 3 months after the first presentation.
Results:
The patient was asymptomatic shortly after she retched up the screw, and at the 3-month follow-up was without evidence of progression of plate dislodgement.
Conclusion:
As reported, oral extrusion of cervical spine grafts or instrumentation is rare but potentially serious. Each case of instrumentation failure should be assessed individually to decide if conservative management is appropriate or if reoperation should be considered.
