Treatment Tactics for Patients with Isolated Injuries of the Fifth Lumbar Vertebra.

UNLABELLED

The major management technique for lumbar burst fractures is transpedicular fixation (TPF). However, in relation to fractures of the L vertebra, this tactic often has no advantages over conservative treatment, and, therefore, it is expected to be supplemented with anterior decompression and reconstruction of the anterior column of the L vertebra. was to determine the most optimal treatment tactics for patients with isolated burst fractures of the fifth lumbar vertebra.

MATERIALS AND METHODS

We performed a retrospective study of 58 patients treated for isolated burst L fractures. 12 patients refused to undergo surgery and received conservative outpatient treatment. TPF was performed in 27 patients; circular spondylosynthesis (TPF + anterior column support with a Mesh implant) - in 19 patients. The effectiveness of the treatment was assessed by clinical and introscopic research methods.

RESULTS

The radiological and functional outcomes of surgery with conventional TPF for isolated L burst fractures are generally comparable with the outcomes of conservative treatment. In 26% of the patients, the instability of the metal construction developed within 12 months after surgical intervention. Supplementing the transpedicular system with wedging anterior column support with a Mesh implant ensures preservation in 21%, and improves the parameters of the sagittal profile of the lumbosacral transition in 79% of cases.
