[Chondrogenic potential of a free autogenous periosteal graft for biological resurfacing over a half-thickness defect in a joint surface: an experimental study].

We report the results of chondrogenesis from a free autograft of periosteum taken from the medial tibial condyle transplanted over a partial-thickness defect created on the medial femoral articular surface in immature white rabbit. A total of 69 rabbits were randomly divided into four groups as follows, Group I received the free autograft and were allowed intermittent activity in a cage. Group II also received a free autograft but were allowed only continuous passive motion in a CPM apparatus for 8 hours a day for the first two weeks after the operation. Group III received a freeze-dried periosteal graft and were allowed intermittent activity in a cage. And Group IV as controls received no graft over the created defect and were allowed intermittent activity in a cage. In specimens from Group I and from Group II at 3 weeks postoperatively, hypertrophic cells were recognized. In both groups at 4 weeks postoperatively, the autograft had sealed the defect with interposition of fiber bundles. At 8 weeks postoperatively, the union of both matrices was clearly demonstrated. The chondrocyte arrangement and matrix bonding was observed to be better in Group II than in Group I. In specimens from Group III at 8 weeks postoperatively, the freeze-dried periosteum had deteriorated without sealing the defect. In Group IV at 8 weeks postoperatively, the surface of the shaved cartilage was irregular and similar to that in arthrosis. These findings indicated that a periosteal free autograft produced bonding between the matrix of the graft and the matrix of the host cartilage, and was therefore effective for chondrogenesis to seal over a joint defect.

[Expression of growth dynamic in the structure of periosteal bone in Anas platyrhynchos].

An experimental study of the periosteal bone growth in the mallard from 42 to 154 post hatching days shows: (1) a noticeable time difference in the local biological age of the diaphyseal cortices between various long bones; (2) great differences in their histological structures, at a given individual age, expressing commensurate differences in local growth rates. Those results emphasize the importance of local factors to interpret the typology of the primary (periosteal) bone tissues. Experimental results allow to quantify the relationships between bone tissue typology and the velocity of its radial deposition.

[Osteogenic capacity of a vascularized periosteal flap tubulized around a coral implant. Experimental study on sheep].

The objective of this study was to evaluate the osteogenic capacities of a vascularized periosteal flap reinforced by a bone substitute, coral, to validate the possibility of creating prefabricated bone flaps with shapes adapted to a recipient zone, while limiting the donor site sequelae. 24 periosteal flaps, with preserved vascular pedicles, were raised from the medial femoral epiphyses of 12 ewes. In the same animal, these flaps were reinforced with a cylinder of coral and a cylinder of autologous graft. After implantation for 2 or 8 weeks depending on the animal, the flaps were submitted to histopathological and histomorphometric examination. The results of this examination demonstrated a similar course of the flaps regardless of the type of reinforcement, both in terms of implant resorption and the quantity of newly formed bone.

Periostitis and osteomyelitis in chronic drug addicts.

Periostitis and osteomyelitis can occur in drug addicts not only by hematogenous dissemination of the infecting organisms, but as a result of introduction of bacteria by direct injection into periosteum or injection through infected skin and subcutaneous tissues. A spectrum of examples of osteomyelitis of the bones of the forearm in drug addicts is presented to illustrate this phenomenon. Neglect of these infections and the trauma of continued injections can lead to extensive tissue and bone loss.

Massive florid reactive periostitis.

Florid reactive periostitis is a rare, benign process usually occurring in the small, tubular bones of the hands and feet. Typically the lesion occurs in an adolescent or young adult and presents as a small area of pain and erythema over the affected bone. Although the histologic features may suggest malignancy, there is usually little radiographic evidence to support such a diagnosis. In the following report an unusual example of this entity is described whose large size and relentless local progression led to initial diagnostic uncertainty and eventual aggressive management. This case suggests that a wide spectrum of radiologic and morphologic changes may be seen in this entity and that a seemingly unrelated genetic disease may alter the typical clinical course.

Laminar periostitis and multiple osteonecrosis in systemic lupus erythematosus.

Bone affectation in systemic lupus erythematosus (SLE) is caused both by the disease itself and by the treatment used. We report the case of a woman diagnosed of SLE, who, in the course of her illness, develops multiple aseptic osteonecrosis (AON) and laminar periostitis, radiologically compatible with the diagnosis of hypertrophic osteoarthropathy (HOA), with no evidence of acropaquia. In this case, the patient shows all the risk factors involved in the pathogenesis of the development of ischemia in bone microcirculation.

Severe toxic osteoblastoma of the humerus associated with diffuse periostitis of multiple bones.

Toxic osteoblastoma is a rare variant of an uncommon primary bone tumour that has been described only once before in the world medical literature. It is characterised by systemic features including fever, weight loss and a striking diffuse periostitis in association with an osteoblastoma, resulting in delayed diagnosis. Early recognition of this condition could prevent inappropriate therapies and reduce morbidity.

The nature of the hyaline rings in chronic periostitis and other conditions: an ultrastructural study.

The hyaline rings found in chronic periostitis and a radicular cyst were investigated ultrastructurally. These rings were composed of fine fibrillar material which was probably derived from degraded collagen fibrils, all of which eventually became degraded and unrecognizable. Foreign-body material in the form of circular bodies of probable plant origin were also found and should not be confused with the hyaline rings.

Periostitis ossificans versus Garrè's osteomyelitis. Part I. What did Garrè really say?

In 1893, C. Garrè published an article dealing with the manifestations of acute osteomyelitis. Since then, his name has been associated with diseases such as Garrè's osteomyelitis, chronic sclerosing osteomyelitis, and periostitis ossificans, among others. Scrutiny of a translated version of the original article reveals that Garrè was not responsible for the description of the disease that now bears his name.

Sclerosing osteomyelitis of Garrè (periostitis ossificans).

The diagnosis of sclerosing osteomyelitis of Garrè, or periostitis ossificans, is suggested by a history of hard swelling of the mandible accompanied by a carious dentition. Computed tomography, nuclear medicine scanning, and pantomography are used to illustrate the appearance of this condition arising in a 25-year-old woman. The differential diagnosis of mandibular thickening and associated bony sclerosis is discussed.

Cranial fasciitis of childhood with reactive periostitis.

We report a rare case of cranial fasciitis in an 11-year-old girl. The patient was found to have an ossifying soft tissue mass over the occiput that was arising from the cranial periosteum and the deep fascial layer. An associated florid periosteal reaction was found in the occipital bone adjacent to the scalp mass. The computed tomography and histologic pattern of this unusual lesion are discussed. A brief review of the literature is included emphasizing the need to investigate further this completely benign lesion that frequently is confused with a malignant neoplasm.

Periostitis and osteitis associated with hyaline bodies.

Twenty four cases of periostitis and osteitis associated with hyaline bodies are reviewed. The condition primarily affects the premolar and molar region of the mandible in patients who wear dentures. It is suggested that exogenous foreign material, especially from leguminous food impacted into the tissues following tooth extraction, is involved in the pathogenesis of the lesions. In dentate patients there are several other routes by which such material could gain access to the deeper tissues.

Takayasu's arteritis presenting with focal periostitis affecting two limbs.

Takayasu's arteritis (TA) is a vasculitis of large and medium sized arteries. Involvement of bone in TA is very rare. We report a case of young woman who presented with multiple painful bone lesions which were identified as periostitis with new bone formation associated with TA. Our case is unique in that bony involvement in TA could occur independent of vascular stenosis.

Epidemiology of odontogenic periostitis.

The frequency of odontogenic periostitis (o.p.) observed during 13 consecutive years was assessed according to sex, age, and the affected pairs of teeth, in subjects admitted to an outpatient department in an area with an unsatisfactory dentist/population ratio. O.p. was less frequent in the older age groups, even after adjustment for the decreasing number of subjects with advancing age. The observed frequencies of o. p. were related in groups with a range of 10 years, both in men and women to the number of teeth present, i. e. "at risk". The last-mentioned figures were calculated for the individual pairs of teeth relying on a population model. the maximum risk of the individual tooth pairs was not found for all teeth in the same age classes but varied, partly in accordance with the caries susceptibilities, though this item was not the determining factor. O. p. is an avoidable sequel of penetrating caries, and as such is one of the consequences of the inadequate health education of the public.

Florid reactive periostitis.

A case of florid reactive periostitis of the thumb is reported. This rare, benign, bone-producing lesion is easily confused with osteosarcoma. It is also known as parosteal or nodular fascitis. Careful histologic and radiographic evaluations are needed to establish the diagnosis and avoid unnecessary amputation. Marginal excision seems to be adequate treatment.
