Comparative Study
Transplantation of human marrow stromal cells and mono-nuclear bone marrow cells into the injured spinal cord: a comparative study.
Two groups of 6 rats received dorsolateral funiculotomies followed by direct injection of bone marrow stromal cells (MSC) or mono-nuclear fraction of bone marrow (mnBM). Animals were killed at 4 or 21 days. ⋯ The use of mnBM is a viable alternative to MSC for transplantation into SCI and may dramatically ease clinical translation.

A retrospective review. ⋯ Dural ossification is a common finding in OLF. There are 2 radiologic signs of dural ossification, namely, the "tram track sign" and the "comma sign." Preoperative identification of dural ossification might help the surgeon to anticipate and appropriately deal with dural laceration during surgery. This will also help to counsel patients regarding the risks of surgery for OLF. The surgical and prognostic implications of dural ossification are being discussed.

Retrospective case series. ⋯ Intralesional resection should be avoided as it is associated with a higher LR rate and worse survival. Rectus abdominus flaps ought to be considered as they lower the wound complication rate. Sacral resection is associated with significant morbidity.

In vitro biomechanical study on 6 fresh frozen human thoracolumbar spine specimens. ⋯ High viscosity vertebroplasty effectively reduced and stabilized thoracolumbar wedge compression fractures and may represent a one-step solution for restoring vertebral body dimensions following thoracolumbar compression fractures, while minimizing the risk of cement leakage and associated complications in vivo.
