[Indentification of lumbar foramina with percutaneous pins. A cadaveric study].
Patients diagnosed with a lumbar disc hernia and nerve root compression, in which conservative treatment failed are candidates for lumbar discectomy. This technique often results in failed spine surgery syndrome which includes different complications such as arachnoiditis, discitis, and sac tears resulting in pain and neurological deficit. This has led to research of minimally invasive surgery in which the medullary canal is not involved and is performed under local anesthesia. In order to perform this technique, the anatomical and radiological identification of the intervertebral foramina is necessary. Kambin's triangle is an anatomical safe place for percutaneous procedures. ⋯ (1) Foramina need to be perfectly identified with image techniques so that the surgical instruments can be placed safely. (2) Skin lines are a safe and reliable guide. (3) The technique is safe if performed through Kambin's triangle.
