Article
Objective Aim of this study was to evaluate the efficacy in reducing post-operative pain and opioid analgesia of a novel inter-disciplinary strategy combining pre-operative Thoraco-Lumbar Interfascial Plane (TLIP) block and percutaneous/endoscopic TLIF surgery. Secondary aims were to determine the time to first postoperative ambulation and hospital...
Article
Background: Open spine surgery usually requires post-operative analgesia with narcotics. The Thoraco-Lumbar Interfascial Plain (TLIP) block is a novel, ultrasound-guided local anesthesia technique that targets the sensory component of the dorsal rami of the thoracolumbar nerves. Study Design: Prospective, non-randomized sequential case series stud...
Article
BACKGROUND CONTEXT Open lumbar spine fusion surgery usually requires opioid analgesia for several weeks during the postoperative recovery period. Recently, a facet-sparing, full percutaneous transforaminal lumbar interbody fusion (TLIF) has been introduced that uses an endoscopic cannula for placement of an interbody cage in combination with percut...
Article
Study design: This was a prospective, multicenter, consecutive case series' study. Objective: The objective of this study was to evaluate a novel facet-sparing, percutaneous transforaminal lumbar interbody fusion (pTLIF) technique consisting of percutaneous insertion of an expandable interbody cage through an endoscopic cannula with the trans-Ka...

Introduction: We evaluated the feasibility of a full percutaneous approach with an expandable interbody cage and an interspinous spacer for a segmental stabilization of the anterior and posterior columns of the lumbar spine, respectively, with local anesthesia. Methods: Patients were prospectively included between 2012 and 2018 in this single-cent...
Article
BACKGROUND CONTEXT Interbody fusion by open discectomy is the usual treatment for degenerative disc disease but requires a relatively long recovery period. The transforaminal posterolateral approach is a well-known standard in endoscopic spine surgery that allows direct access to the disk with progressive tissue dilation, avoiding tissue and bone d...
Chapter
The standard treatment for degenerative disk disease is interbody fusion by open discectomy. However, this technique requires open tissue dissection with the disadvantages of higher risk of infection, blood loss and a relatively long recovery period.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be i...

The invention proposes a device for minimally invasive intervention in the skeletal region, in particular on the spinal column, having at least a cannula with a distal end generally bevelled in shape relative to a symmetrical axis of the cutting tool and an optical probe (endoscope) for insertion through the cavity of the cannula. The device is fur...
Chapter
Study Design. Prospective study. Objective. The purpose of this study was to assess the clinical outcome of three endoscopic lumbar disc techniques: selective endoscopic discectomy (SED), intracanal transforaminal endoscopy (ITE), and an interlaminar endoscopy (ILE). Summary of Background Data. A number of percutaneous endoscopic procedures for lum...
Chapter
This chapter discusses endoscopically assisted transforaminal percutaneous lumbar interbody fusion. Degenerative disc disease (DDD) is associated with diminished disc height and painful symptomatology. The usual treatment is highly invasive lumbar interbody fusion (transforaminal lumbar interbody fusion [TLIF], posterior lumbar interbody fusion [PL...

Hydrogels are water-insoluble hydrophilic polymers used in a wide range of medical products such as, drug delivery, tissue replacement, heart surgery, gynaecology, ophthalmology, plastic surgery and orthopaedic surgery. These polymers exhibit low toxicity, reduced tissue adherence, and are highly biocompatible. A class of hydrogels, hydrolysed poly...
Article
Clinical series of patients with degenerative disk disease undergoing an endoscopic posterolateral transforaminal procedure that used a reaming foraminoplasty technique to enlarge the foramen coupled with insertion of the B-Twin expandable spacer. This retrospective analysis of 107 consecutive patients sought to assess the outcome of this surgical...

A case of a 79-year-old male patient complaining of low back pain for 1 year is reported. His symptoms were aggravated in the last 3 months. The magnetic resonance imaging showed a grade I spondylolisthesis at L4-5 level with severe central stenosis. In order to achieve maximal posterior opening of the L4-5 level we chose to fuse the L4-5 level wit...

This article presents a new endoscopic procedure: transforaminal endoscopic stenosis surgery (TESS). This technique is performed through a posterolateral transforaminal approach and allows the foramen in a collapsed lumbar disc to be widened by undercutting the superior facet under direct endoscopic control. A new endoscopic small reamer is used fo...

We sought to construct a general methodology for objectively quantifying the learning curve associated with any surgical technique and to determine the number of cases needed to achieve a success rate of 90% for the technique of transforaminal endoscopic lumbar discectomy. To our knowledge, no other studies have observed the learning curve of endos...
Article
Owing to recent advances in the diagnosis and treatment of lumbar disc pathology, the functional results obtained have improved, although there are still certain factors which affect this. The results in the work place are particularly problematic. With the aim of finding an answer to the problem of relapse of the sciatica syndrome in patients oper...

Se estudia la repercusión funcional motora de la patología discal lumbar sobre la marcha. Se analiza, por medio de plantillas con sensores que permiten registrar las presiones bajo el pie de forma dinámica, la marcha de pacientes afectos de patología de la columna vertebral lumbar susceptible de ser intervenida quirúrgicamente, para establecer la p...
