Abstract:

BACKGROUND: The three-dimensional stability of middle-upper thoracic pedicle screw fixation is the best. But because of narrow and thin thoracic pedicle and spinal cord within the thoracic spinal canal, it is of high difficulty and risk for this internal fixation.
OBJECTIVE: To explore the clinical effects of middle-upper thoracic semi-pedicular fixation via a posterior approach.
METHODS: Fifty-eight patients with upper thoracic diseases were treated with middle-upper thoracic semi-pedicular fixation via a posterior approach. Screws of 4.5 mm in diameter and 30 mm in length were used at T1-2, and screws of 5.0-6.0 mm in diameter and 35-40 mm in length used at T3-8.
RESULTS AND CONCLUSION: Postoperative thoracic X-ray films and CT showed no screws entered the spinal canal, and spinal sequence recovered well, without internal fixation loosening and breakage and other complications. There was no spinal cord injury, infection and other complications. All the patients recovered normal life, and pain disappeared in 16 cases. Forty-six patients with incomplete and complete paraplegia could take care of themselves, chest and back pain disappeared, and no kyphosis occurred. The middle-upper thoracic semi-pedicular fixation via a posterior approach is reliable, safe and easy, which can be used as a good choice for middle-upper thoracic posterior fixation.
