Background: Unstable sacral fractures are high-energy injuries and comprise polytrauma. Internal fixation to enable withstanding vertical loads is required to get up early from the bed after an unstable sacral fracture. We developed a new minimally invasive surgical (MIS) procedure for unstable pelvic ring fractures and reported it in Japanese in 2010.

Study Design: A retrospective study.

Objective: The aim of this study was to determine the incidence of increased segmental range of motion (ROM) after laminoplasty and to clarify whether increased ROM is associated with spondylolisthesis. Finally, we explored the effect of increased segmental ROM on clinical results.

Article Synopsis
  • Reconstruction of large bone defects after removing cancerous tumors poses challenges, with a common treatment involving autogenous irradiated bone grafting facing issues like nonunion due to loss of healing capacity from irradiation.
  • The study tested a method using osteogenic matrix cell sheets from bone marrow cells, co-transplanting them with irradiated bone in a rat model, showing promising results in bone healing.
  • X-ray and imaging results revealed significant bone repair and strength at the irradiated site, suggesting that this technique could be an effective option for treating bone defects in patients after tumor resections.

Background Context: Revision surgery after laminoplasty is rarely performed, and there are few reports of this procedure in the English literature.

Purpose: To evaluate the reasons why patients underwent revision surgery after laminoplasty and to discuss methods of preventing the need for revision surgery. A literature review with a comparative analysis between previous reports and present cases was also performed.

Article Synopsis
  • - The study aimed to assess if osteogenic matrix cell sheets (OMCS) could promote bone formation around grafted tendons in rabbits, which might aid in early tendon-to-bone healing after surgery.
  • - Researchers found that OMCS had strong osteogenic properties, demonstrated by high alkaline phosphatase activity and positive bone formation indicators when tested with grafted tendons.
  • - Results showed that OMCS significantly increased bone volume and pullout strength at the tendon-bone interface compared to controls, suggesting that OMCS can effectively enhance tendon-to-bone healing post-surgery.

An 80-year-old woman presented with neck pain and paraparesis of Frankel C in her upper and lower extremities after falling. Imaging revealed an ankylosing cervical spine and a fracture line running obliquely from the anterior C3-4 to the posterior C4-5 level. Posterior fixation from the occi pit to T3 was performed using the RRS Loop Spine System and concomitant polyethylene tape fixation.
