The periosteum is a thin membrane that surrounds the outer surface of bones and participates in fracture healing. However, the molecular signals that trigger/initiate the periosteal reaction are not well established. We fractured the rat femoral bone at the diaphysis and fixed it with an intramedullary inserted wire, and the expression of regenerating gene (Reg) I, which encodes a tissue regene...

background and aims. connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. the aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. materials and methods. in this single-blind randomized spli...

The foundations of Orthopaedics are a great deal better supported with evidence today than previously. Nonetheless, superstitions and myths have not completely disappeared. One of them is the role of the periosteum in fracture healing. The anatomy and physiology of the periosteum under normal circumstances have been studied for many a decades, and its role in the growth and development of tubul...

The periosteum and Sharpey's fibre extensions occupy the musculoskeletal interface and may be strategic in age-related deterioration. Because of its exceptionally powerful insertions the porcine mandible is an ideal model and its periosteal system was compared in 4 separate regions of adult young (1 year) and older (3 year) animals. These were examined by undecalcified histology, collagen immun...

There are many techniques for the treatment of hip dysplasia, and novel research is currently being undertaken in the hope of obtaining more efficient and less traumatic techniques. The denervation of the hip joint capsule is a simple and effective technique that allows recovery of the functional activity of the affected limbs in significantly less time than other techniques. This surgical proc...

The sympathetic nervous system controls bone remodeling by regulating bone formation and resorption. How nerves and bone cells influence each other remains elusive. Here we modulated the content or activity of the neuropeptide Vasoactive Intestinal Peptide to investigate nerve-bone cell interplays in the mandible periosteum by assessing factors involved in nerve and bone behaviors. Young adult ...

BACKGROUND: Aggressive carcinomas of the scalp usually occur in elderly patients with multiple comorbidities. Complete excision of this type of tumor often involves the removal of periosteum, and the resulting defects can be difficult to reconstruct. OBJECTIVE: To evaluate the usefulness of porcine type I collagen dressings as adjunct or definitive treatment in the surgical closure of scalp def...

BACKGROUND The distal saphenous nerve is commonly known to provide cutaneous innervation of the medial side of the ankle and distally to the base of the great toe. We hypothesize that the saphenous nerve innervates the periosteum of the medial malleolus and joint capsule. METHODS Five fresh limbs were dissected and the saphenous nerve was traced distally with magnification. The medial malleol...

In an experimental study using the Göttingen minipig, Gore-Tex, Gore Resolut, and Vicryl barrier membranes were tested for their efficacy in guided bone regeneration. The results were compared to those of autologous periosteum. The strongest reossification was seen in the bone defects covered with Gore-Tex; however, time-dependent disintegration phenomena, which had already been observed in pre...
