“…In regard to the disadvantages of FFG, it has been reported that the FFG sometimes migrate into the epidural space and that neurological symptoms are aggravated by compression of the spinal cord [5,12]. However, only dorsal laminectomy was performed in these previous studies.…”

“…Therefore, it was considered that compression of the spinal cord by FFG would never happen. The primary cause of compression of the spinal cord is migration of the FFG into the peridural space through the defect [5]. Consequently, there is a possibility that FFG migration would be controlled physically if the size of the defect could be reduced.…”

“…Placement of an autogenous free fat graft (FFG) over the defect to act as a cover that separates the exposed dura mater and surrounding tissue has been reported as an effective solution to this problem. On the other hand, it has also been reported that migration of the FFG into the epidural space aggravates the neurological symptoms [5,12]. However, in these reports concerning the complications of laminectomy and the usage of FFG, only dorsal laminectomy was performed, and there have been no reports concerning hemilaminectomy to date.…”

ABSTRACT. The purpose of this study was to evaluate the effect of an autogenous free fat graft (FFG) on hemilaminectomy defects. Hemilaminectomy was performed at three levels in three beagles, and each defect was designated as a control site or a site treated with one of two different sizes of FFG. Subsequently, longitudinal computed tomography scanning and histopathological examination were performed. As a result, no postoperative dural adhesion was recognized at the sites where FFGs were placed regardless of the size of the FFG. Moreover, there was no compression of the spinal cord by the FFG. Therefore, it appears that postoperative dural adhesion was controlled by the FFG and that the possibility of FFG migration into the spinal canal is low in hemilaminectomy. In conclusion, placement of an FFG over the defect was considered useful for preventing complications in hemilaminectomy.

“…Algumas complicações podem ser encontradas em pacientes humanos (Lee et al 1990) e animais (Jones et al 2000, Da Costa et al 2006) submetidos à laminectomia como a formação de fibrose epidural (FE) (Toombs & Waters 2003, Almeida et al 2008.

“…Entre as principais sequelas pode-se citar a dor (Jones et al 2000) e as deficiências neurológicas (Trotter et al 1988, Da Costa et al 2006. A FE ocorre devido às aderências mecânicas do tecido cicatricial fibroso com a dura-máter, raízes nervosas (Kemaloglu et al 2003, Cabukoglu et al 2004) e mús-culos epaxiais (Lee et al 1990).…”

The purpose of this study was to isolate the adjacent epaxial musculature from exposed spinal cord by modified dorsal laminectomy in dogs with aluminum implant and to verify whether the muscles contribute to form epidural fibrosis, spinal cord compression, and development of neurological signs. Ten dogs were submitted to modified dorsal laminectomy between T13 and L1 and then distributed along two groups. Dogs in the group 1 remained with the spinal cord exposed without the implant; dogs in the group 2 had an aluminum implant inserted between the epaxial muscles and the exposed spinal cord. Neurological examination was daily performed until 180 days post surgery. Additionally, myelography at 15, 30, and 60 days post surgery and macroscopic evaluation of the implant at six months post surgery were done. There was no difference between groups in the neurological examination. A statistical difference in the degree of spinal compression was observed at day 15 post surgery in the group 2. In this group, the epaxial musculature adjacent to the spinal cord was not in contact with the epidural fibrosis, differently to what was observed in the control group. The implant was removed easily with some degree of deformity. The results showed that the adjacent musculature of the spinal cord submitted to a modified dorsal laminectomy in dogs can be isolated by aluminum implant, without any contact with epidural fibrosis or influence in the development of neurological signs.
