Bai J, Zhang W, Zhang X, Sun Y, Ding W, Shen Y - Med. Sci. Monit. (2015)

Bottom Line: The differences in contralateral foramen area and disc-height index(DHI) before and after surgery were compared between Group S and a random sample of 40 cases of non-symptomatic group patients (group N).The time of symptom appearance, duration, and symptomatic severity (JOA VAS score) were compared between Group T and O.Compared with Group T, the symptoms of Group O patients appeared earlier, persisted longer, and were more serious (p<0.05).

ABSTRACT

Background: The aim of this study was to analyze treatment outcomes and morbidity of contralateral neurological symptom in patients after TLIF surgery and to explore its possible causes.

Material and methods: A retrospective study was conducted involving a total of 476 patients who underwent TILF from 2009 to 2012 in our hospital. These cases were divided into a symptomatic group (Group S) and a non-symptomatic group. The differences in contralateral foramen area and disc-height index(DHI) before and after surgery were compared between Group S and a random sample of 40 cases of non-symptomatic group patients (group N). In addition, according to whether the patient underwent second surgery, Group S patients were further divided into a transient neurologic symptoms group (Group T) and an operations exploration group (Group O). The time of symptom appearance, duration, and symptomatic severity (JOA VAS score) were compared between Group T and O.

Results: Among the 476 patients, 18 had postoperative contralateral neurological symptoms; thus, the morbidity was 3.7815%. The indicators in Group S were lower than in Group N in the differences in contralateral foramen area and disc-height index(DHI) before and after surgery (p<0.05). Five patients (Group O) in Group S had second surgery because of invalid conservative treatment. The surgical exploration rate was 1.0504%. Compared with Group T, the symptoms of Group O patients appeared earlier, persisted longer, and were more serious (p<0.05).

Conclusions: Contralateral neurological symptom is a potential complication after TLIF, and its causes are diverse. Surgical explorations should be conducted early for those patients with the complication who present with obvious nerve damage.

f4-medscimonit-21-1831: Group S patients (n=16) – foramen area change before and after the operation (postoperative – preoperative) composition.

Mentions: This study analyzed and compared the difference in contralateral foramen area and DHI before and after surgery between the symptomatic group and non-symptomatic group. The results show that patients in the symptomatic group had smaller contralateral foramen area and DHI (Table 1). The comparison of the intervertebral foramen area change before and after surgery in the symptomatic group showed that the postoperative contralateral foramen area was not generally increased, as previously thought, but instead, most of them were reduced (Figure 4).
