Single-stage treatment of lumbar fracture–dislocation using a combined anterior and posterior approach

Progression of Diagnostic Imaging Findings of a Patient With Traumatic Spondylolisthesis Secondary to Unilateral Facet Fractures: A Case Report

“…15 In the case of a high-risk mechanism of injury to the lumbar spine (eg, falls N3 m, ejection from a motor vehicle, and motor vehicle crashes N50 mph [80 kph]), timely referral to the specialist and advanced imaging is recommended under the guideline when there is absence of clinical improvement after 4 to 6 weeks of therapy, function does not improve or deteriorates, or persistent signs or symptoms are present. 16 In our case, the neurosurgical consultation was delayed to 10 months after trauma, and the standard patient management was relegated from the lack of communication between providers.…”

Traumatic Spondylolisthesis of the Fourth Lumbar Vertebra Without Neurologic Deficit or Fracture of the Posterior Elements

“…Successful pedicle screw fixation was applied in all the patients, except in two cases with L4spondylolisthesis [8,13]. The insertion of an intravertebral cage in 12 out of 18 cases [2,3,5,6,9,[12][13][14]16,17] resulted in solid fusion and reportedly restoration of sagittal balance.…”

“…The combination of hyperextension, hyperflexion, and rotation has been described [1] as a pathogenic mechanism. Moreover, L4/L5 traumatic dislocation is extremely rare, since only 16 studies in the literature have reported anterolisthesis, retrolisthesis, or even spondyloptosis of L4, with or without neurologic impairment [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Among the 18 patients reported, only five cases have been reported with L4-anterolisthesis Meyerding III with "locked" but not fractured facets [5,[15][16][17].…”

“…Patients' age averaged 31.9±14.52 years in the published papers, but there were four patients with ages lower than 20 years [3,8,11] ( Table 1). Eleven out of the 18 patients were admitted with neurologic impairment [3,4,[9][10][11][12][13][15][16][17]. Neurologic injury was more common in patients with L4 retrolisthesis.…”

“…Especially, spondylolisthesis of the fourth lumbar vertebra (L4) is very rarely reported, while several cases with dislocation of the fifth lumbar vertebra (L5) over the first sacral vertebra (S1) have been described [1]. To our knowledge, there are only 16 studies with 18 patients reporting on L4 traumatic anterolisthesis, retrolisthesis, and spondyloptosis with or without concomitant fracture of the posterior vertebral elements [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Most of the patients in these reports were treated operatively with open reduction, intervertebral cages, pedicle screws, and rods fixation via the posterior approach.…”
