Posterior segmental fixation for thoraco-lumbar and lumbar fractures: a comparative outcome study between open and percutaneous techniques


Showing results of open and percutaneous surgical management of traumatic AO type A3, A4 and B2 thoracic and lumbar fractures.


Retrospective comparative analysis of traditional open fusion versus percutaneous navigated fixation of thoracic and lumbar spinal fractures. Minimum 24 months follow-up to collect ODI and VAS outcome scores for comparative analysis was required.


Fifty-seven patients with a mean age of 39 years met the inclusion criteria. Twenty-six patients were in the open group (Group O) and 31 in the percutaneous group (Group P). The majority of fractures were either type A3 or A4; there were three type B chance fractures in Group O and one in Group P. VAS and ODI scores followed comparable trends in the two groups until the final follow-up. The main statistically significant result between the two groups was blood loss, which was lower in Group P (110 versus 270 ml in Group O on average), although this did not reflect into different clinical outcomes. Similar peri-operative measures of operating time and length of stay were found between the two groups. A significantly higher degree of loss of reduction was noted at follow-up in Group P (8° versus 5° in Group O on average).


Open and percutaneous posterior fixation techniques of thoracic and lumbar fractures in this cohort were associated with different perioperative blood losses as well as radiological measurements, but not with clinically meaningful differences in patient reported outcome measures at 24 months’ follow-up.
