Results
In the study, preoperative and postoperative data were analyzed. There were 28 women (56%)
and 22 men (44%). The mean age was between 30-52 years (± 4,873 STD). Preoperative JOA
score was mean 10,84 (±1,983) and spread between 8-15. The mean postoperative JOA score
is 25.24 (±1,349) and is spread between 22-28. Patient monitoring mean follow-up period is
36,14 (±7,513) and spread between 24-49. Statistical analysis showed that there was no
significant difference between the groups regarding age, gender, disk level, and preoperative
JOA. The average preoperative JOA score of all patients in the group without making a
distinction between 10,84 (±1,983) and the average postoperative JOA score was 25,24
(±1,349) and was found to be statistically significant. The mean recovery rate was 79.19
(±7.700) among all patients. Three groups regarding postoperative clinical results were
compared. There was no significant difference between the groups concerning mean
postoperative JOA score and recovery rate. While there was no significant difference between
the three groups regarding preoperative pain (group OD 1,00±0,85, group DSTFO 0,94±0,79
and group DDS 1,04±0,96), postoperative pain score in group DSTFO (2,75±0,42) and DDS
group (2,9±0.28) is significantly higher than the other group (OD 2,2±0,94). Group DDS was
higher regarding postoperative lower back pain scores than group DSTFO. But it was
concluded that there was no statistical difference.
A patient in group OD had a recurrence disk development 18 months after the operation. In
the examinations, the same level of instability was detected. This patient underwent
discectomy, transpedicular screw insertion, and posterolateral fusion again. In the follow-up,
three patients in Group OD and two patients in Group DSTFO developed back pain. MRI was
scanned, and no recurrence disc was detected. These patients recovered completely with
conservative treatment. In three cases in the group OD, dural injury, infection in one case and
deep vein thrombosis in one case developed. DSTFO also developed Dural injury in one case
and infection in one case. In the group DDS, dural injury developed in one case and
neurological deficits developed in one case. The infection developed in groups is superficial,
and the infection has been completely healed with appropriate treatment. Dural injuries were
repaired with primer and dural vein thrombosis was treated with conservative and
anticoagulant therapy.
There was a statistically significant difference between groups regarding intraoperative blood
loss compared to group DSTFO (451,76±45,171) and DDS (447,65±47,635), to group OD
(178,75±40,804). However, there was no statistically significant difference between Group
DSTFO and group DDS. There was a statistically significant difference between groups
DSTFO (3,82±0,809) and DDS (3,00±0,707) regarding the duration of hospitalization
compared to group OD (1,75±0,856). However, there was no statistically significant
difference between Group DSTFO and group DDS.
