Peripheral Nerve Procedures

Endoscopic Carpal Tunnel Release (ECTR)

The primary goal in this surgery is to release the transverse carpal ligament (TCL) that overlies and compresses the median nerve within the carpal tunnel. It is this compression on the median nerve that leads to the characteristic ‘pins and needles’ paresthesia in the thumb, index, long and ring fingers. The primary benefit of endoscopic releases versus traditional open carpal tunnel release is often perceived to be the smaller incision size. ECTR incisions are commonly less than 1 cm (0.39 in) compared to a 2–4 in (51–100 mm) longitudinal incision with a traditional carpal tunnel release. However, the incision size is not the only factor that differentiates the two methods. The principle behind the endoscopic release is that the Palmar aponeurosis, a thick tough layer of tissue that lines the palm, is not divided with endoscopic methods. In addition, the endoscopic methods offer less dissection and interruption of tissue planes than the open methods because the endoscopic methods do not divide the subcutaneous tissues or the palmar fascia to the same degree as the open method does. Thus, a more rapid recovery is generally touted with ECTR as the normal skin above the TCL is not incised. Surgery, either open or endoscopic is a way to treat Carpal Tunnel Syndrome. A meta-analysis supports the conclusion that endoscopic carpal tunnel release is favored over the open carpal tunnel release in terms of a reduction in scar tenderness and increase in grip and pinch strength at a 12-week follow-up (Wikipedia referenced)

Spinal Cord Simulation

A device used to exert pulsed electrical signals to the spinal cord to control chronic pain, or motor disorders. Spinal cord stimulation (SCS), in the simplest form, consists of stimulating electrodes, implanted in the epidural space, an electrical pulse generator, implanted in the lower abdominal area or gluteal region, conducting wires connecting the electrodes to the generator, and the generator remote control. SCS has notable analgesic properties and, at the present, is used mostly in the treatment of failed back surgery syndrome, complex regional pain syndrome and refractory pain due to ischemia.
