[Biomechanical study of polymethyl methacrylate bone cement and allogeneic bone for strengthening sheep vertebrae].

Objective: To investigate the feasibility and mechanical properties of polymethyl methacrylate (PMMA) bone cement and allogeneic bone mixture to strengthen sheep vertebrae with osteoporotic compression fracture.

Methods: A total of 75 lumbar vertebrae (L -L ) of adult goats was harvested to prepare the osteoporotic vertebral body model by decalcification. The volume of vertebral body and the weight and bone density before and after decalcification were measured.

A bone substitute composed of polymethyl-methacrylate bone cement and Bio-Gene allogeneic bone promotes osteoblast viability, adhesion and differentiation.

Background: Increasing reports on new cement formulations that address the shortcomings of PMMA bone cements and various active components have been introduced to improve the biological activity of PMMA cement.

Objective: Evaluating the biological properties of PMMA cements reinforced with Bio-Gene allogeneic bone.

Methods: The MC3T3-E1 mouse osteoblast-like cells were utilized to determine the effects of Bio-Gene + PMMA on osteoblast viability, adhesion and differentiation.

Comparison of posterior lumbar interbody fusion (PLIF) with autogenous bone chips and PLIF with cage for treatment of double-level isthmic spondylolisthesis.

Introduction: Spondylolytic defects involving multiple vertebral levels are rare. It is reported that only 1.48% of patients with back pain were diagnosed with multi-level spondylolysis.

Lumbar intraosseous schwannoma: case report and review of the literature.

Intraosseous schwannomas of the mobile spine are extremely rare. To our knowledge, only 21 cases have been reported in the literature. In this report, we present a case of schwannoma involving the lumbar spine, with a review of the literature and discussion of this rare tumor.
