Percutaneous Cement Discoplasty for Degenerative Low Back Pain with Vacuum Phenomenon: A Multicentric Study with a Minimum of 2 Years of Follow-Up.

Background: To report clinical results after percutaneous cement discoplasty (PCD) in a multicentric case series with a minimum of 2 years of follow-up.

Methods: Between December 2014 and January 2019, 180 patients with low back pain and advanced degeneration were treated with percutaneous discoplasty in 2 centers. The inclusion criteria were as follows: patients 65 years or older, with mechanical low back pain with or without spinal stenosis, who did not respond to conservative management.

Clinical and radiological outcomes after stand-alone ALIF for single L5-S1 degenerative discopathy using a PEEK cage filled with hydroxyapatite nanoparticles without bone graft.

Objective: Recent improvements in cage designs with integral fixation and screw attachments have made stand-alone ALIF a viable option with several possible advantages. The aim of this study was to confirm the efficacy and safety of a PEEK cage filled with hydroxyapatite nanoparticles without adding a bone graft for stand-alone ALIF in the treatment of L5-S1 isolated degenerative disc discopathy (DDD).

Patients And Methods: Sixty-five patients who required surgery for DDD were evaluated.

[Segmental sternal dislocation in children. Apropos of a surgically treated case].

The authors report one operated case of traumatic sternal segmental dislocation in a child, and propose a mechanism for this uncommon lesion. A fourteen year old boy was admitted in emergency for anterior chest pain, occurring during an exercise in parallel bars without any fall. X ray showed traumatic dislocation of the upper sternal segment.

[Transperitoneal laparoscopic approach to the L5-S1 disk. Value of computed x-ray tomography].

Purpose Of The Study: The aim of this study was to determine the laparoscopic approach of L5-S1 disk, by preoperative C.T. evaluation.

[Lumbar-iliac fixation using the Cotrel-Dubousset instrumentation in pelvic fractures. Apropos of 3 cases].

Purpose Of The Study: The authors propose the use of Cotrel-Dubousset instrumentation in pelvic ring fractures with posterior trans-sacral disruption. They report 3 cases, describe the operative procedure and analyse the advantages and inconveniences of this method.

Material: 3 patients, injured after hand-gliding fall, presented at their admission, a fracture of the pelvis with associated lesions: the first one had a pelvic ring fracture type C2 (according to TILE classification), several associated fractures (femur, ankle, wrist), and brain trauma.
