title: Basilar invagination secondary to hypoplasia of the clivus - Is there indication for craniocervical fixation?

description: The posterior fossa decompression is a form of treatment suggested for patients with basilar invagination (BI) secondary to hypoplasia symptomatic of the clivus and atlantoaxial alignment preserved. Based on the fact that the worsening of cranial-cervical kyphosis (decrease of clivus-canal angle to less than 150o) can result in anterior brainstem compression, we propose that some patients may benefit from the cranio-cervical fixation. We present a case report of a patient with BI secondary to clivus hypoplasia who underwent cranio-cervical fixation in extension, with a reduction in clivus-canal angle and improvement of symptoms without posterior fossa decompression.

title: Effectiveness of the surgical intervention in the quality of life and survival of patients with metastatic lesions in the spine

description: OBJECTIVE: To evaluate the impact of surgical treatment of metastatic epidural spinal lesions on the quality of life of patients, pain relief and survival. METHODS: Patients with single or double spinal lesions, in good clinical conditions to undergo surgery, were included. Staging and prognostic evaluation were performed, based on imaging studies, according to the criteria of Enneking and Tokuhashi, and neurological status (Frankel), pain (visual analogue scale, VAS) and quality of life index (Oswestry) were also assessed. Survival was calculated. RESULTS: The study included 67 patients, 34 men and 33 women, aged 13-88 years (mean: 53). Most had the breast (23 cases) as the primary site of the tumor and metastasis in the lumbar region, especially in L2 and L3. Pathologic fractures were diagnosed in 45 patients. The mean VAS score was initially 9 (5-10) reducing in the second day after surgery to 2 (1-7) and to 1 (0-6) in the first and sixth months. Following 6 months, 18 deaths were observed (one intraoperatively, five in the first month and 12 at 6 months). The neurological status was correlated with survival: patients who were Frankel E before surgery showed increased survival. CONCLUSION: The surgery does not influence patient survival, except for patients with neurological deficits, who have a worse prognosis. Treatment of metastatic lesions is often palliative, but patients present improved neurological and pain relief and few complications after surgery, justifying surgical intervention.

title: Traumatic lumbar espondylolisthesis: a case report

description: We present a case of traumatic espondylolisthesis L5 S1 A0 53 B3.3 ASIA B in a young patient after a high energy car accident. This entity is a rare injury that requires immediate attention. Treatment should be prompt in order to provide the best prognosis since this is an unstable and severe lesion that presents with neurological deficit in half of the patients. Computed tomography and magnetic resonance imaging have shown to be extremely valuable for the diagnosis and are mandatory for this kind of injuries. In this case it is noteworthy that the intervertebral disk was intact. It is reported that if surgery is performed 24 to 48 hours after the accident, the improvement of neurological deficit is very feasible. In this case posterolateral fusion with autologous bone graft and multiplanar transpedicular posterior instrumentation and decompression were performed 52 hours after the accident. The patient presents one year after surgery with improvement in movement and sphincter control and with radiographic evidence of a complete fusion.

title: Two-level total disc replacement with Mobi-C(r) over 3-years

description: Objective: To evaluate the safety and effectiveness of two-level total disc replacement (TDR) using a Mobi-C(r) Cervical Artificial Disc at the 36 month follow-up. Methods: a Prospective, randomized, controlled, multicenter clinical trial of an artificial cervical disc (Mobi-C(r) Cervical Artificial Disc) was conducted under the Investigational Device Exemptions (IDE) and the U.S. Food & Drug Administration (FDA) regulations. A total of 339 patients with degenerative disc disease were enrolled to receive either two-level treatment with TDR, or a two-level anterior cervical discectomy and fusion (ACDF) as control. The 234 TDR patients and 105 ACDF patients were followed up at regular time points for three years after surgery. Results: At 36 months, both groups demonstrated an improvement in clinical outcome measures and a comparable safety profile. NDI scores, SF-12 PCS scores, patient satisfaction, and overall success indicated greater statistically significant improvement from baseline for the TDR group, in comparison to the ACDF group. The TDR patients experienced lower subsequent surgery rates and a lower rate of adjacent segment degeneration. On average, the TDR patients maintained segmental range of motion through 36 months with no device failure. Conclusion: Results at three-years support TDR as a safe, effective and statistically superior alternative to ACDF for the treatment of degenerative disc disease at two contiguous cervical levels.

title: Total cervical disk replacement with a prestige LP® prosthesis: clinical and functional outcomes

description: Objective: To determine the clinical and functional results of short- and medium-term cervical arthroplasty with the Prestige LP® prosthesis for the treatment of compressive myelopathy, radiculopathy and axial pain with radiculopathty. Methods: This retrospective study, conducted from 2009 to 2012, included 18 patients. Only 16 were found for the second stage of research, conducted in 2011 and 2012. Pre- and postoperative assessments were carried out using the CSOQ (Cervical Spine Outcomes Questionnaire). Odom criteria were used only in the postoperative evaluation. Both were translated and adapted to the local culture. Results: There was no postoperative radiculopathy or other complications requiring prolonged hospitalization. In most patients, there was a significant improvement in axial pain and radiculopathy, and there was only one indication of conversion to fusion. Conclusions: In selected cases of cervical degenerative disc disease, herniated cervical disc and compressive myeolopathy, cervical arthroplasty proved to be an effective and safe treatment in the short and medium terms.

title: Thickness of the ligamentum flavum of the spine and its relationship with disc degeneration

description: Objective: This study investigates whether the thickening of the ligamentum flavum (LF) is correlated with disc degeneration. Methods: This retrospective study was conducted with 98 patients with chronic low back pain treated in a spinal surgery service between January 2012 and January 2013. All patients underwent magnetic resonance imaging (MRI) and the images were evaluated by a spinal surgeon to measure the thickness of the LF and evaluate the degree of disc degeneration by the Pfirrmann grading system, according to the spinal levels (L3 -L4, L4-L5, L5-S1). An association was sought between LF hypertrophy and disc degeneration, age, sex and disc height. Results: The mean age of the patients was 53.6 years, and the majority were women (59.2%). The thickness of the LF and disc height varied according to the spinal level, the greatest LF thickness being found between L4-L5, and the greatest disc height at L5-S1. Women had statistically thicker ligaments in L3/L4 than men. The degree of disc degeneration was inversely correlated with the height at all the levels evaluated, i.e., the greater the degree of degeneration, the lower the disc height. Conclusions: The thickening of LF is not related to disc height or degree of disc degeneration. Therefore, there is no deformation of the LF within the spinal canal secondary to disc degeneration.

title: Knowledge and attitudes of low back pain in physicians based in clinical practice guidelines

description: Objective: To determine the level of knowledge and attitudes of physicians in Tijuana based on Clinical Practice Guidelines (CPG) for the prevention, diagnosis and treatment of Nonspecific Low Back Pain (NLBP). Methods: Prospective, cross-sectional, descriptive study. Data were obtained from doctors who practice in clinics, private surgeries, and/or government institutions. Results: Of a total of 56 doctors surveyed, 37 were men and 19 women. None of the doctors said they had not seen a patient with Back Pain. 49% knew the GPC, and 51% did not know of its existence. Conclusions: Although some physicians reported knowledge of the GPC, according to the results, there was a lack of full knowledge of, and adherence to these guidelines. Not knowing the GPC did not make it impossible to complete the questionnaire. The doctors felt more connected to the health system, but with less confidence in the management of cases of NLBP.

title: Frequency of spondylolysis and chronic low back pain in young soccer players

description: Objective: To demonstrate the safety of soccer for adolescents in terms of chronic lesions of the lumbar spine, particularly spondylolysis. Methods: 54 young players underwent a pre-season assessment. The athletes were submitted to radiography of the lumbosacral spine. Players complaining of chronic low back pain were later submitted to more specific tests. Results: only 1 athlete (1.85 % of our sample) had complaints of chronic low back pain. In this case, the radiograph showed olisthesis grade I spondylolysis at the L5 level. Conclusion: Soccer proved to be a very safe sport in terms of the risk of developing chronic lesions of the lumbosacral spine. However, the actual incidence of spondylolysis in these athletes was not determined because only plain radiographs were used in this study.

title: Comparison of the results of MIS-TLIF and open TLIF techniques in laborers

description: Objective: To compare clinical outcomes in laborers who have undergone open transforaminal interbody fusion (TLIF) and minimally invasive transforaminal interbody fusion (MIS TLIF). Methods: 78 patients were submitted to lumbar arthrodesis by the same two spine surgeons partners from January 2008 to December 2012. Forty-one were submitted to traditional open arthrodesis and 37 to the minimally invasive procedure. Three patients were not included because they had already retired from work. The analyzed variables were length of hospitalization, length of follow-up, type of access (TILF or MIS TLIF), need for blood transfusion, percentage of improvement or worsening after surgery, pre- and postoperative VAS scale, time off work, pre-and postoperative Oswestry disability index, and general aspects of the laborers such as age, education, profession, working time, amount of daily weight carried at work, and use or not of personal protective equipment. Results: Time off work was longer in the TLIF group (average of 9.84 months) compared with the MIS TLIF group (average of 3.20 months). Significant improvement in postoperative VAS and Oswestry was achieved in both groups. Average length of hospitalization was 5.73 days for the TLIF group and 2.76 days for the MIS TLIF group. Conclusions: Minimally invasive transforaminal lumbar interbody fusion presents similar results when compared to open TLIF, but has the benefits of less postoperative morbidity, shorter hospitalization times, and faster rehabilitation in laborer patients.
