(no author information available yet)
Dural tears (DT) and the consequent cerebral spinal fluid (CSF) leak are not rare in spine surgeries. CSF leak can be troublesome, leading to pseudomeningocele, cutaneous CSF fistula, and meningitis. Revision surgery is unavoidable in some cases. The reported incidences of DT and CSF leak are different according to the various pathologies. Ossification of the posterior longitudinal ligament, revision spine surgery and multi-segment laminectomy have higher risks for DT. Various techniques have been described to manage this complication, such as bed rest, repair with dural substitutes, fibrin glue, gelatin sponge, lumbar drain, muscle flap, etc...

BACKGROUND: Minimally invasive spine surgery (MISS) has been increasingly advocated during the last decade with new studies being reported every year. Minimally invasive spine procedures, such as minimally invasive transforaminal interbody fusion (MI-TLIF), have been introduced to reduce approach-related muscle trauma, to minimise blood loss, and to achieve faster wound healing, quicker ambulation and earlier patient discharge. METHODS: The aim of this article was to give a comprehensive review of the available English literature comparing open TLIF with MI-TLIF techniques published or available online between 1990 and 2014 as identified by an electronic database search on http://www...

BACKGROUND: Patients who experience percutaneous endoscopic lumbar discectomy (PELD) recurrence need to undergo revision surgery when they fail to respond to conservative therapy. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), microendoscopic discectomy (MED) and PELD are three common minimally invasive surgical approaches for PELD recurrence. However, there have been no studies that have focused on the selection of the minimally invasive surgical method for PELD recurrence...

Luigi La Barbera, Tomaso Villa
Mechanical reliability tests on posterior spine stabilization devices are based on standard F1717 by the American Society for Testing and Materials, which describes how to assemble the implant with vertebrae-like test blocks in a corpectomy model. A recent study proposed to revise the standard to describe the anatomical worst-case scenario, instead of the average one currently implemented, and introduce the unsupported screw length as a mechanical parameter. This article investigates the implications of such revisions on the endurance properties of an implant already on the market...
