Posterolateral musculo-fascial approach to the lumbar spine intervertebral discs: anatomical study

Objective: assess an anatomical and topographic parameter of the wound channel formed when using the posterolateral muscular-fascial approach to determine the possibility of its clinical use for performing decompressive-stabilizing surgical interventions. Material and methods: on the material of 20 cadavers of both sexes with different body mass index (mean 25.1 ±2.9) aged 54 to 76 years (median 67.5 years), who died from diseases not associated with the pathology of the spine, was modeled the posterolateral muscular-fascial approach to the lumbar spine. During the research were studied wound length, wound depth, wound depth index, access zone and the angle of intersection of the wound edges and the surface of surgical instruments.
