Bilateral spondylolysis of inferior articular processes of the fourth Lumbar Vertebra: a case report
Upsala journal of medical sciences, 2011Co-Authors: Tomoaki Koakutsu, Naoki Morozumi, Takeshi Hoshikawa, Shinji Ogawa, Yushin Ishii, Eiji ItoiAbstract:Lumbar spondylolysis, a well known cause of low back pain, usually affects the pars interarticularis of a lower Lumbar Vertebra and rarely involves the articular processes. We report a rare case of bilateral spondylolysis of inferior articular processes of L4 Vertebra that caused spinal canal stenosis with a significant segmental instability at L4/5 and scoliosis. A 31-year-old male who had suffered from low back pain since he was a teenager presented with numbness of the right lower leg and scoliosis. Plain X-rays revealed bilateral spondylolysis of inferior articular processes of L4, anterolisthesis of the L4 Vertebral body, and right lateral wedging of the L4/5 disc with compensatory scoliosis in the cephalad portion of the spine. MR images revealed spinal canal stenosis at the L4/5 disc level. Posterior Lumbar interbody fusion of the L4/5 was performed, and his symptoms were relieved.

Giant cell tumor of fifth Lumbar Vertebrae: two case reports and review of the literature.
The Spine Journal, 2006Co-Authors: Yoichi Shimada, Shigeru Ando, Yuji Kasukawa, Michio Hongo, Naohisa Miyakoshi, Eiji ItoiAbstract:Abstract Background context complete or total en bloc spondylectomy has been recommended for giant cell tumors of the spine. Wide local resection of the fifth Lumbar Vertebra carries potential risks of major complications because of its anatomical features. Only nine cases of the giant cell tumors involving the fifth Lumbar Vertebra have been reported in the literature. Purpose to present two cases of giant cell tumor of the fifth Lumbar Vertebra treated by single-stage combined anterior and posterior tumor resection over 7 years of follow-up. Study design Case report and a review of literature. Methods A 33-year-old female and a 20-year-old female, each diagnosed with giant cell tumor of fifth Lumbar Vertebra, underwent single-stage tumor resection through a combined posterior and retroperitoneal anterior approach. Results The resection of the fifth Lumbar Vertebra was completed in the first case without major perioperative complications. In the second case, massive bleeding during the anterior procedure for resection of the Vertebral body interrupted the total resection of the tumor, resulting in possible residual tumor which required adjuvant radiotherapy. The patients recovered both clinically and neurologically after the operation. Spinal reconstruction was maintained, and no recurrence of the tumor was evident at the 7-year and 8-year follow-up, respectively. Conclusion There was no recurrence of the tumor after the combined single-stage anterior and posterior tumor resection and adjuvant radiotherapy for the second case for over 7 years follow-up. However, complete resection of the Vertebra and tumor at the fifth Lumbar Vertebra is still challenging to accomplish.

congenital malformation of fifth Lumbar Vertebra a case report
International Journal of Research in Medical Sciences, 2013Co-Authors: Jugesh Khanna, Renu ChauhanAbstract:Fifth Lumbar Vertebra is an atypical Vertebra as it has widely separated inferior articular processes and thick transverse processes projecting out from the body and pedicles of the Vertebra. On routine examination of osteology specimens we found a fifth Lumbar Vertebra in two separate parts. One part consisted of body, pedicles, transverse and superior articular processes. The other part consisted of lamina, spinous and inferior articular processes. Knowledge of this variation may be of importance to the clinicians for diagnosis of certain neurological deficits in the lower limb and to orthopaedic surgeons and neurosurgeons during the surgical intervention of that area.

burst fracture of the fifth Lumbar Vertebra results of posterior internal fixation and transpedicular bone grafting
European Spine Journal, 2002Co-Authors: Artur Kaminski, E. J. Müller, Gert MuhrAbstract:Burst fractures of the fifth Lumbar Vertebra are rare, and there are only a few reports on this subject, which is characterised by its unique anatomical and biomechanical features. This retrospective analysis reports on ten patients whose fractures of L5 were stabilised with a short internal fixator in combination with a posterior fusion as well as transpedicular bone grafting. The average follow-up period was 22 months. Radiometric data were surveyed and compared to the functional results. The height of the fractured Vertebra remained nearly unchanged throughout the course. Loss of lordosis of 4° in the upper disc space and 4° in the lower disc space were observed postoperatively. At the time of follow-up, the values of segmental Lumbar lordosis were significantly below the preoperative level. The narrowing of the neural canal was reduced from 57% to 28% with the surgical intervention. However, there was no correlation between the functional and the radiological outcome. Neurological deficits were documented in two patients, which declined during the course. There were no severe postoperative complications. The results of the present study demonstrate that the described surgical procedure in fractures of the fifth Lumbar Vertebra does not promote an anatomic restoration of the fractured Vertebra, nor of the segmental lordosis. However, the clinical results do not correlate with the radiological outcome. Nonoperative treatment with early mobilisation without external support seems to be the treatment of choice.
