Abstract
STUDY DESIGN
A retrospective single-center study.
OBJECTIVE
We aimed to compare the clinical outcomes of cervical spine fracture accompanied with ankylosing spondylitis (ASCSF) treated by single posterior approach (PA) and combined anterior-posterior approach (CA) for patients who were followed up for >1 year.
SUMMARY OF BACKGROUND DATA
For ASCSF patients, surgical treatment has been widely accepted as a recommendable therapeutic option. But the optimal surgical approach is still under controversy, and few studies have focused on the comparison between PA and CA.
MATERIALS AND METHODS
From February 2007 to March 2019, 53 patients were enrolled and divided into the PA group (34 cases) and CA group (19 cases). Their general characteristics and clinical materials were recorded. From the aspects of reduction distance, bone fusion, neurological functional restoration, and postoperative complications, patients' surgical outcomes were evaluated qualitatively and quantitatively.
RESULTS
The reduction degree of dislocation (mean PA=2.05 mm, mean CA=2.36 mm, P=0.94) was close between the 2 groups. Besides, with a similar follow-up period (P=0.10), the rate of bone fusion (both 100%) and neurological functional restoration (PA=31.03%, CA=35.29%, P=0.77) were also without significant difference. The occurrence rate of postoperative complications tended to be higher in the CA group (31.58% vs. 23.53%) but with no significant difference (P=0.52). Nevertheless, the surgical duration time (mean=209.15 min) and blood loss (average=388.91 mL) of PA group were significantly less than CA group (mean duration time=285.34 min, mean blood loss=579.27 mL) (P<0.01).
CONCLUSIONS
Compared with to the CA approach and with the equally significant outcome, surgery by single PA was feasible and should be positively recommended for ASCSF patients, especially for those accompanying with a severe chin-on-chest deformity or poor physical conditions which restrain patients from tolerating a long surgery or major surgical trauma.
