“…[12][13][14] Transforaminal access, whether open or minimally invasive, promotes complete exposure of the posterolateral aspect of the intervertebral disc, requiring minimal retraction of nerve roots and dural sac in order to perform the intersomatic arthrodesis, and the insertion of an intersomatic spacer. [15][16][17] The retractors are used merely as protectors during the proper preparation of the intersomatic space and insertion of the bone graft and spacer. The separation of tissues is therefore unilateral and minimal, significantly reducing the risk of neural injury caused by traction and manipulation.…”

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.Keywords: Arthrodesis; Lumbar vertebrae; Spinal fusion; Minimally invasive surgical procedures; Occupational health. rEsUMO Objetivo: Comparar resultados clínicos emtrabalhadores braçais submetidos à artrodese transforaminal aberta (TLIF) e minimamente invasiva (MIS-TLIF

“…The surgical technique in all cases was Transforaminal Lumbar Interbody Fusion (TLIF) associated with bilateral pedicle screw fixation, through a minimally invasive transmuscular approach, as described in a previous paper. 3,4 Treatment was indicated and conducted by the two main authors. Inclusion criteria were degenerative disease in a single lumbosacral segment, associated with low back pain, with or without associated radicular symptoms, not responsive to at least tree months of conservative treatment, and availability of the patient to attend the follow-up visits.…”

Objective: To evaluate the impact of a minimally invasive lumbar one-level fixation on trunk mobility and quality of life compared with the preoperative condition in 26 consecutive patients. Methods: The following data were collected preoperatively and postoperatively for the statistical analysis: maximal trunk extension and flexion angles, Visual Analog Scale of pain and Oswestry Disability Index scores. Results: There was improvement in all variables. Statistical significance was observed in trunk extension, pain, and Oswestry Disability Index. Although mobility in trunk flexion was higher in average values after surgery, this difference was not statistically demonstrated. Conclusion: Minimally invasive one-level lumbar fixation does not cause reduction of trunk flexibility in comparison to the mobility before surgery.

Dores na coluna lombar são as reclamações mais comuns em ortopedia, apresentando prevalência anual de 38% em todo o mundo. Dentre suas causas, destacam-se doenças ou traumas sobre os discos intervertebrais, como síndrome facetaria, hérnias de discos, espondilose e síndrome do disco degenerativo. Um dos possíveis tratamentos para esta enfermidade é a alocação cirúrgica de um disco artificial, composto por duas placas de metais biocompatíveis e um núcleo esponjoso. O uso de metal biocompatível diminui os riscos de rejeição pelo corpo humano, sendo a liga de Titânio Ti-6Al-4V um dos biomateriais mais utilizados neste tipo de aplicação. Ligas de titânio, contudo, possuem características de transformação mecânica peculiares, como alta resistência ao escoamento, à abrasão, e dureza elevada, tornando seus processos de fabricação mais complexos, desgastando ferramentas de usinagem rapidamente, tornando a remoção de material mais dispendiosa. Estudos sobre forjabilidade destas ligas configuram-se em área de interesse da engenharia. Assim, visando à diminuição nos custos de ferramental e aumento da produtividade, o presente estudo se propôs a avaliar a viabilidade do forjamento a quente da liga de titânio Ti-6Al-4V para produção de próteses de disco intervertebral. Escolheu-se uma das placas do disco intervertebral, sendo modelada em software de CAD, projetando-se e usinando-se matrizes para forjamento a quente voltadas a este processo, sendo beneficiadas com tratamento térmico de têmpera e revenimento. Resistências elétricas foram dimensionadas teoricamente e alocadas nas ferramentas para o aquecimento das matrizes. As próximas etapas serão os forjamentos planejados e as caracterizações mecânicas e metalúrgicas das peças obtidas.
