Sacral Prosthesis Substitution as a System of Spinopelvic Reconstruction After Total Sacrectomy: Assessment Using the Finite Element Method.

Background: Following total sacrectomy, the continuity between the spine and pelvis is necessary for ambulation and to enable patients to resume daily living activities sooner during rehabilitation. Reconstructing spinopelvic stability after a total sacrectomy is a challenge that has not yet been overcome. Thus, the objectives of the present study are as follows:Establish a new system of reconstructing the spinopelvic region after a total sacrectomy using a rapid prototyping technique to design the sacral replacement pieces.

How good are the outcomes of instrumented debulking operations for symptomatic spinal metastases and how long do they stand? A subgroup analysis in the global spine tumor study group database.

Background: The benefits of surgery for symptomatic spinal metastases have been demonstrated, largely based on series of patients undergoing debulking and instrumentation operations. However, as cancer treatments improve and overall survival lengths increase, the incidence of recurrent spinal cord compression after debulking may increase. The aim of the current paper is to document the postoperative evolution of neurological function, pain, and quality of life following debulking and instrumentation in the Global Spine Tumor Study Group (GSTSG) database.

Spinal osteoid osteoma recurring as an aggressive osteoblastoma.

We report an uncommon case of osteoid osteoma recurring as an aggressive osteoblastoma of the spine. A 15-years-old male consulted in our department with long-term painful scoliosis. The CT-scans and MRI revealed a sclerotic bone forming tumor of 7mm diameter consistent with a osteoid osteoma.

A novel risk calculator to predict outcome after surgery for symptomatic spinal metastases; use of a large prospective patient database to personalise surgical management.

Aim: Surgery for spinal metastases can improve symptoms, but sometimes complications can negate the benefits. Operations may have different indications, complexities and risks, and the choice for an individual is a tailor-made personalised decision. Previous prognostic scoring systems are becoming out of date and inaccurate.

Loss of Local Tumor Control After Index Surgery for Spinal Metastases: A Prospective Cohort Study.

Background: As survival after treatment for symptomatic spinal metastases increases, the incidence of local tumor recurrence also may increase. However, data regarding incidence and timing of recurrence or duration of survival after second surgeries are not readily available and may help to inform clinicians when to perform second surgeries.

Objective: To identify features associated with loss of local control (LLC) at a previously treated or new spinal level.

Expansive laminoplasty as a method for managing cervical multilevel spondylotic myelopathy.

Study Design: This study evaluated 12 patients with multilevel cervical spondylotic myelopathy who underwent Kurokawa's procedure using hydroxyapatite spacers and performed with T-saw thread wire.

Objectives: To assess the efficacy and safety of Kurokawa's laminoplasty for patients with multilevel cervical spondylotic myelopathy using the T-saw, and to determine the radiographic and clinical factors that correlate with the prognosis.

Summary Of Background Data: Spinous process-splitting laminoplasty as an alternative or a combined method with an anterior approach was evaluated for the management of multilevel stenosis of the cervical spine.
