Abstract:

BACKGROUND: Anterior cervical discectomy and subtotal vertebrectomy/titanium cage fixation are the main therapies for patients with poor outcomes of conservative treatment for cervical spondylosis or those with neurological symptoms of the nerve root following cervical injuries or vertebral fractures.
OBJECTIVE: To conclude the reasons and preventive measures for screw loosening following anterior cervical plate fixation.
METHODS: Among 41 cases of cervical spondylosis and cervical injuries undergoing anterior cervical fixation plate, there were 3 cases of screw loosening. The causes and control methods were analyzed and proposed to reduce the anterior plate incidence of screw loosening.
RESULTS AND CONCLUSION: Three cases of screw loosening presented with varying degree of dysphasia. After diagnosed, second operation was performed within 2 weeks to adjust the position of re-fixed titanium screw, and the long-term observation showed patients with good symptom relief. The surgical indications and the choice of the rational application of internal fixation devices as well as the correct postoperative management is the key to prevent screw loosening.
