Enneking et al. examined the process of local spread of primary bone and soft tissue tumors of the extremities and proposed a “surgical staging system” and “the concept of compartment and anatomic barriers.”17 Applying this concept to the spine, we studied the histology of 19 vertebral tumor specimens resected by TES. We found that the following tissues served as barriers to spinal tumor progre...

DESCRIPTION A 31-year-old man with known history of paraplegia presents to clinic with a long-standing wound as shown earlier. The wound is located in the presacral region with intact periosteum, healthy overlying fascia, and no purulence.

BACKGROUND The histological characteristics of periosteum make it a specific tissue with a unique capacity to be engineered. Higher flexibility of the greater omentum is useful for reconstructive surgery as it facilitates not only filling of the site of infections such as myelitis, but also is effective in filling complicated defects of the soft and hard tissues, and these criteria make it suit...

P hyseal or growth plate injuries comprise 18% of all pediatric fractures, with Salter Harris type II as the most common type of fracture injury pattern observed in 61% of patients. The incidence of growth arrest is just over 1%, and the incidence of serious complications is less than 1%. Irreducible physeal fractures, caused by entrapment of the periosteum, tendons or ligaments, are of particu...

Sinus lift augmentation is a procedure required for the placement of a dental implant, whose success can be limited by the quantity or quality of available bone. To this purpose, the first aim of the current study was to evaluate the ability of autologous periosteum-derived micrografts and Poly(lactic-co-glycolic acid) (PLGA) supplemented with hydroxyl apatite (HA) to induce bone augmentation i...

Fig. 1. Schematic of one-stage bone-transport procedure (yellow – bone, red – periosteum). A portion of diaphyseal bone is denuded of periosteum, osteotomized, and transported over an intramedullary nail to the site of the 2.54-cm critical-sized defect, where it is docked to the distal femur. The periosteal sheath is left in situ to surround the new defect site, leading to full infilling of the...
