A paraspinal foreign body reaction is a rare condition that can cause severe neurological complications or death. However, the condition is often neglected. The authors report a case of a paraspinal textiloma that was diagnosed and treated with a surgical excision.

Anterior interbody fusion has used for instability and anatomical reconstruction in various cervical diseases since 1958 by cloward. Bone grafts such as autograft, allograft, xenograft and synthetic materials were utilized in fusion as a graft material. But conventional fusion materials have problems including postoperative morbidity, transmission of diseases, foreign body reaction, collapse, prolongation of operation time. A new synthetic material, Biocompatible Osteoconductive Polymer(B.O.P) is developed and it was useful for cervical anterior interbody fusion as a substitute for other fusion materials.

Several agents are in use to promote new bone formation during bone graft procedures in maxillofacial region. Among them, we have used crude BMP, PRP, and P-15 for experimentally created defects with accompanying graft materials in the rabbit model. The aim of this study is to analyze the effect of above mentioned agents on bone formation using histologic and histomorphometrical methods, thus to provide experimental support for clinical application of these agents. Six rabbits were used as experimental animals. Four surgical defects were created on the distal femoral heads of each animal using trephine drill. The defects were filled with each agents with accompaning graft materials as experimental groups and particulate cortico- cancellous autogenous graft as control. For histomorphometric analysis, fluorescent dye was injected at 2week and 1week before sacrifice. Then, the animals were sacrificed at 2, 4 and 8weeks after surgery and histologic and histomorphometric examinations were achieved. At two weeks after bone graft, bone formation and active remodeling process were examined in all experimental groups and the control. But the intensity of such activities of the experiments were somewhat weaker than that of the control. In BMP group, the amount of newly formed osteoid was increased constantly and the amount was preserved constantly in PRP group. But in P-15 group, the amount of newly formed osteoid was decreased with time to 8week after surgery. Histologic findings showed superior bony quantity and quality in PRP group than that of P-15 group. MAR(Mineralization Apposition Rate) of all experimental groups were slower than that of control group. In P-15 group, constant foreign body reaction was observed at all periods and the graft material showed inwardly destroyed characteristics rather to mature. The data from this study provide the basis for future studies for evaluating the long-term remodeling process and foreign body reactions observed in P-15 group and clinical study for predictable use of these agents.

Several mechanisms about venous flap were proposed. Among them, plasmatic imbibition and early revascularization are supposed to be the most important factors for the survival of venous flap. Many reports about the role of plasmatic imbibition have used silastic sheet or other foreign material to block the plasmatic imbibition so that foreign body reaction might affect the survival of the flap. No experiment has been reported to examine the revascularization directly. We blocked the plasmatic imbibition by marginal resection around the venous island flap and delayed venous island flap and placing it onto the bare cartilage to exclude the effect of foreign body. We also examined the revasularization of the delay and non-delay venous island flap directly using microfil cast. As a result blocking of the plasmatic imbibition markedly decrease the survival of the flap but the survival of delay flap is about five times that of non delay flap. Revascularization was minimal at 1 week postoperative day. It is inferred that plasmatic imbibition is more important than revascularization.

We report a case of a 40-year-old man with a traumatic epidermal cyst on the lateral malleolus. It was unusual that the cyst contained glass pieces as a foreign body, which did not induce foreign body reaction in both clinical and histopathological aspects. To our best knowledge, this is the first case of an epidermal cyst to manifest as a foreign body cyst containing glass pieces in cystic contents.
