En bloc resection in patients younger than 16 years affected by primary spine tumors: indications, results and complications in a series of 22 patients.

Purpose: Review a series of 22 patients below the age of 16 affected by primary bone tumors of the spine who underwent en bloc resection, and describe the clinical presentation, tumor characteristics, results and complications associated with the surgical treatment, underlining the specific issues related to a younger age.

Methods: We performed a review of all patients < 16 years old affected by primary bone tumors of the spine, surgically treated with en bloc resection from 1996 to 2016. Clinical and radiological characteristics, therapy, complications and survival are reported.

The Gore-Tex biomaterial mesh as temporary divisor in two times surgery for spinal and pelvic tumors.

In muscular skeletal spine and pelvic tumor, surgery can be performed by a double anterior and posterior approach to decrease the risk of bleeding and opening the tumor; in first one, neurovascular bundles are divided by the mass; in second one, the tumor is resected by posterior or postero-lateral approach. A Gore-Tex mesh could be used as divisor between neurovascular bundles and the tumor to decrease the adhesion formation risk and facilitate tumor removal during second operation if performed after more days. The cohort was composed by a consecutive series of 11 patients underwent to surgery for spine and pelvic tumor where Gore-Tex mesh spacer was placed.

The role of FDG-PET in distinguishing between septic and aseptic loosening in hip prosthesis: a review of literature.

Infection in prosthesis surgery is very dangerous because it changes the patient's prognosis. Differential diagnosis between septic and aseptic loosening is fundamental in order to apply the correct treatment. The correct diagnostic approach is still debated in literature.
