Comparison of the ablation ability of nucleus pulposus after 1,064 nm Nd:YAG laser and 980 nm diode laser radiation.

Objective: To compare the ablation ability of nucleus pulposus after 1,064 nm Nd:YAG laser and 980 nm diode laser radiation.

Methods: Goat spine specimen (GSS) was radiated using Nd:YAG laser and 980 nm diode laser and then divided into five groups based on the final energy--200, 400, 600, 800 and 1,000 J groups. The ablation quality of nucleus pulposus after radiation was recorded.

Efficacy of percutaneous laser disc decompression on lumbar spinal stenosis.

The objective of this study is to observe the effect of percutaneous laser disc decompression (PLDD) on lumbar spinal stenosis (LSS). Thirty-two LSS patients were treated using pulsed Nd: YAG laser, of which 21 cases (11 males and 10 females with an average age of 64 years old) were followed up for 2 years. All of the 21 patients had intermittent claudication with negative straight leg raising test results.

Mid-term efficacy of percutaneous laser disc decompression for treatment of cervical vertigo.

Objective: To observe and analyze the mid-term efficacy of percutaneous laser disc decompression (PLDD) for the treatment of cervical vertigo.

Methods: Thirty-five patients with cervical vertigo were admitted from September 2002 to December 2006, including 14 males and 21 females, aged between 35 and 79 years with an average of 59.1 years.

Efficacy evaluation of percutaneous laser disc decompression in the treatment of lumbar disc herniation.

Objective: The purpose of this study was to evaluate the efficacy of percutaneous laser disc decompression (PLDD) in the treatment of lumbar disc herniation (LDH) and identify the relationship between PLDD efficacy and age.

Background Data: Many articles have shown that the short-term clinical outcome of PLDD was fairly good. However, the continuous follow-up results over 3 years of PLDD for LDH treatment are rarely reported, and little is known about the relationship between PLDD efficacy and age.
