“…Holmium:yttrium-aluminum-garnet (Ho: YAG) laser (VersaPulse; Lumenis, Yokneam, Israel) was used to ablate the posterior annulus and the PLL with minimal thermal necrosis. Ho: YAG laser is effective for (1) internal decompression within the posterior annulus at the initial stage, (2) shrinkage and resecting of the thickened posterior annulus around the annulus tear, (3) resecting of the PLL for exposing ventral epidural space for removal of transligamentous extrusion, and (4) resection of osteophyte or traction spur [ 2 , 11 , 17 , 18 ].…”

Thoracic disc herniation and stenosis are relatively rare, and various symptoms make them difficult to diagnose. Due to the complexity of neural and vascular structure, surgical treatment of thoracic pathology is challenging. Endoscopic spine surgery is an emerging minimally invasive surgical option. Based on wide experience on the cervical and lumbar spine, an endoscopic approach for the thoracic pathology can be performed beyond the learning curve. Transforaminal approach for thoracic disc herniation, endoscopic unilateral approach, and bilateral decompression for thoracic stenosis have been reported as favorable and safe surgical options. In the present study, the authors described the detailed surgical procedure as well as tips and tricks.

“…Lee et al 35 have reported that in a cadaveric study on temperature distributions of the lumbar intervertebral disc during laser annuloplasty, the temperature would rise upon irradiation and fall slowly with the cessation of irradiation, and the most distinctive elevation of the temperature was observed from probes located 3 mm away from the laser fiber tip, both in depth and lateral positions. Li et al 28 reported that 2 out of 220 patients experienced a burning sensation in the ipsilateral lower limb during the thermal procedure using Ho:YAG laser, which disappeared when the Ho:YAG laser ablation stopped. This sensation was possibly related to the high temperature generated by vaporization of the Ho:YAG laser.…”

“…The clinical application of lasers has been widely used in orthopedics, including spinal surgery. 24,25 To date, various types of lasers in spinal surgery have been reported in clinical or experimental studies, including the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser, 26,27 holmium:YAG (Ho:YAG) laser, [28][29][30] and CO2 laser. 31 Among them, Ho:YAG laser has a wavelength of 2.1 μm and reaches a depth of <0.5 mm in tissue.…”

Introduction:For the aging population, surgery for lumbar spinal canal stenosis (LSCS) requires minimally invasive procedures. Recently, trans-sacral epiduroscopic laser decompression for lumbar disc herniation has been reported with good results. In this study, we devised a new method to perform trans-sacral epiduroscopic laser ablation of the ligamentum flavum (LF), known to be the major cause of LSCS. Using a live pig, this study aims to evaluate the efficacy, safety, and drawbacks of this procedure.Methods: Using an epiduroscope, we observed intra-spinal canal structures and then examined the feasibility and problems of a decompression procedure to ablate the LF using holmium:YAG (Ho:YAG) laser. The pig was observed for behavioral changes and neurological deficits after the procedure.Histological analysis was performed to evaluate the amount of tissue ablation and damage to surrounding tissues. Results:Although it was possible to partially ablate the LF using the Ho:YAG laser under epiduroscopy, it was difficult to maintain a clear field of view, and freely decompressing the target lesion has been a challenge. After the first two experiments, the pig neither showed abnormal behavior nor any signs of pain or paresis. However, in the third experiment, the pig died during the operation. On autopsy, no thermal or mechanical injury was noted around the ablated site, including the dura mater and nerve root.
