Changes in spino-pelvic alignment after surgical treatment of isthmic spondylolisthesis.

Background And Purpose: To analyze the changes in spino-pelvic parameters after surgical treatment of lumbar isthmic spondylolisthesis.

Materials And Methods: Sixty patients recruited from a group of consecutive series of 128 cases with isthmic spondylolisthesis operated on between 2002 and 2012 in the Department of Neurosurgery, Tarnow, Poland. All patients were operated on by the same surgeon (the first author).

Posterior keyhole corpectomy with percutaneous pedicle screw stabilization in the surgical management of lumbar burst fractures.

Objective: The authors present a new method of minimally invasive surgical management of lumbar burst fractures through the posterior approach. The method includes minimally invasive corpectomy and interbody fusion, both of which are performed through a keyhole approach, and percutaneous pedicle screw fixation of the fracture. The technique of the posterior keyhole corpectomy presented in this report is a novel and original concept of the first author (AM).

[Minimally invasive posterior corpectomy of the lumbar spine with transpedicular fixation].

The authors present their experience in the minimally invasive posterior keyhole lumbar corpectomy with transpedicular stabilization. This technique involves the removal of the posterior part of the affected vertebral body with the pedicle screw fixation through four 2-3 cm long skin incisions on the back. Two cephalad skin incisions provide an approach for corpectomy and instrumentation of the upper pedicles of the construct.
