Laser research and development has focused on medical uses since the 1960's. Historically, low level lasers (LLL) have been the predominant type of light therapy used, but more recently light emitting diode (LED) has been studied. Results have shown the LED to be effective as a coadjutant treatment for wound healing, inflammation, neurodegenerative disease and pain, including potential for neurosurgical patients. Light emitting diode is a semiconductor light source that uses p n junction which is made of thin heavy layered semiconductor materials. Near infrared (NIR-LED) therapy emits radiation from the near-infrared region of the electromagnetic spectrum, with wavelengths ranging from around 630 nm to 940 nm. William Herschel is credited with the discovery of near-infrared during the early 1800s, while development of industrial uses was not done until the 1950s. Today, NIR radiation is used in night vision goggles, digital cameras, and remote controls for daily activities.

Although 100 years have passed since neurosurgical specialties appeared, there is still no protection from the vacuum power on the neurosurgical cannula tip. Material and MethodThe neurological suction control; valve were analyzed, physics, engineering and surgical were examined. books, journal and PubMed, social media and anecdotal were evaluated.

Kienbock's disease is a relatively rare disorder where the blood supply to one of the small bones in the wrist is interrupted. The affected bone, the lunate, is one of eight small carpal bones that is in the middle at the base of the wrist and is responsible for wrist movement. This case study examines an otherwise healthy white 71 year old female with extreme wrist pain, initially diagnosed by the provider as tiny ganglion cysts in the ulnar tissue but later appropriately diagnose Kienbock's left wrist with ulnar minus. This case study will study the care of the wrist using a 940nm near-infrared light emitting diode.Background: There is no cure for Kienbock's disease, but prompt treatment can help preserve wrist function and relieve pain. Kienbock's disease progresses through four stages; loss of blood flow, sclerosis of bone, breakdown of lunate bone, and finally the breakdown of the remaining bones of the hand (Allan et al., 2001). The rate of progression is varied from case to case. Objective:To evaluate the effects of the near infrared light emitting diode on inflammation and bone healing. Materials and method:This article investigates the role of near infrared light emitting diode on the sclerosis of the lunate carpal bone, stage one of Kienbock's disease.A review of books, journals, PubMed, and physician notes Discussion: Using the near infrared light emitting diode (NIR LED), healing rate has increased, a decrease in inflammation, bone regeneration, and pain has minimized. The NIR LED gallium arsenide can be used as an adjunctive therapy for reduction for this progressive disease.
