ReviewBalloon kyphoplasty in patients with osteoporotic vertebral compression fractures.
Balloon kyphoplasty (BKP) is a minimally invasive surgical procedure indicated for treatment of painful vertebral compression fractures. During BKP, cannulae are placed percutaneously into the vertebral body, allowing insertion of inflatable balloons. Inflating the balloons partially restores vertebral body height, compacts the bone and creates a cavity for placement of bone cement after balloon removal. ⋯ Clinically significant adverse events have been rarely reported. These findings were confirmed in randomized and nonrandomized prospective controlled studies. The objective of this review is to describe the surgical procedures involved in BKP and to review the evidence supporting its use.

ReviewTransforaminal percutaneous endoscopic lumbar discectomy: technical tips to prevent complications.
Transforaminal percutaneous endoscopic lumbar discectomy is regarded as an effective alternative to open discectomy. Remarkable technical evolution now enables selective endoscopic removal of an epidurally extruded disc fragment. As a result, the surgical indications for this technique are becoming broader. ⋯ Initial landing should be as close to the target as possible. Complete herniotomy after thorough release of annular anchorage is a key to success. The definitive end point of the procedure is free mobilization of neural tissues, not direct exposure of neural tissues.
