[Treatment of old scaphoid fracture with transposition of vascularized periosteal flap and internal fixation].

OBJECTIVE: To introduce an effective method of treating old scaphoid fracture. METHODS: From April 1995 to April 2002, 11 patients with old scaphoid fracture were treated with transposition of vascularized periosteal flap and internal fixation; if necessary, the radial styloid was removed. Out of 11 patients( 8 males and 3 females, aged from 17 to 46 years), the fracture sites were medial scaphoid in 7, the proximal one in 2 and the distal one in 2. The X-ray films showed separated fracture lines. The fracture lines were less than 1 mm in 4 patients and more than 1 mm in 3 patients. Sclerosis of skeleton ends and cystoid degeneration occurred in 2 patients, respectively. RESULTS: After a follow-up of 3 to 24 months, the fracture healing was obtained within 4 months in 9 cases and within 6 to 7 months in 2 cases. Internal fixation was taken out 3 months after bone healing. The carpal joint pain and weakness vanished in all cases. CONCLUSION: Transposition of vascularized periosteal flap and internal fixation have many advantages, such as easy dissection, rich blood supply, quick new bone formation, short time of fracture healing and satisfactory function recovery of carpal joint.

[Tissue engineered bone regeneration of periosteal cells using recombinant human bone morphogenetic protein 2 induce].

OBJECTIVE: To investigate bone regeneration of the cell-biomaterial complex using strategies of tissue engineering based on cells. METHODS: Hydroxyapatite/collagen (HAC) sandwich composite was produced to mimic the natural extracellular matrix of bone, with type I collagen serving as a template for apatite formation. A three-dimensional poly-porous scaffold was developed by mixing HAC with poly(L-lactic acid) (PLA) using a thermally induced phase separation technique (TIPS). The rabbit periosteal cells were treated with 500 ng/ml of recombinant human bone morphogenetic protein 2 (rhBMP-2), followed by seeded into pre-wet HAC-PLA scaffolds. Eighteen 3-month nude mice were implanted subcutaneously cell suspension (group A, n = 6), simple HAC-PLA scaffold (group B, n = 6) and cell-biomaterial complex (group C, n = 6) respectively. RESULTS: Using type I collagen to template mineralization of calcium and phosphate in solution, we get HAC sandwich composite, mimicking the natural bone both in composition and microstructure. The three dimensional HAC-PLA scaffold synthesized by TIPS had high porosity up to 90%, with pore size ranging from 50 microm to 300 microm. SEM examination proved that the scaffold supported the adhesion and proliferation of the periosteal cells. Histology results showed new bone formation 8 weeks after implantation in group C. The surface of group A was smooth without neoplasma. Fibrous tissue invasion occurred in group B and no bone and cartilage formations were observed. CONCLUSION: The constructed tissue engineering bone has emerged as another promising alternative for bone repair.

Case report: Periosteal Ewing's sarcoma: case report and literature review.

Ewing's sarcoma is a round-cell tumor that arises most often in a medullary cavity. This neoplasm is uncommon in a subperiosteal location. We report a new case of a 12-year-old boy with a periosteal Ewing's sarcoma, located in the femur, who was treated by cortical segmental resection associated with chemotherapy. Two years after surgery the patient was free of disease. In reviewing the literature of 29 cases, it seems the prognosis is better in periosteal compared with intramedullary Ewing's sarcoma.

[A preliminary approach of covering corrugator with rectangle periosteous flap in rhytidectomy].

OBJECTIVE: To evaluate the aesthetic outcome after application of rectangle periosteous flap to cover corrugator. METHODS: On the basis of regular rhytidectomy, a inter-eyebrow periosteous flap is applied to cover the fascia flap of corrugator by means of turnover. This manipulation helps to separate the skin from the muscle and prevent the re-adherence between the skin and muscle. RESULTS: The approach was applied on 15 cases. The follow-up ranged from 6 months to 1 year. The results were satisfactory. CONCLUSIONS: The method is effective in elimination of inter-eyebrow crease.

Static indentation test for neocartilage surface hardness in repair of periosteal articular cartilage defects.

The objective of this study was to determine whether hardness of the superficial layer is a useful parameter to characterise cartilage produced by periosteal neochondrogenesis, using rabbit knee lesions as a model. A cartilage defect was created in the right hind knee of anesthetised young adult rabbits, and the defect was then covered with an autologous periosteal graft. At one and eight months postsurgery, rabbits were euthanised, and the articular cartilage lesion sites were evaluated for the histological parameters in a modified O'Driscoll scale, which is the current 'gold standard' for new cartilage properties. In addition, a static indentation test was performed, using a Shore-A sclerometer to measure surface hardness of the new cartilage. The hardness values had a statistically significant, positive correlation with the O'Driscoll parameters. This combination of a biomechanical measure and the O'Driscoll scale provided a more definitive indicator of graft quality. The results suggest that a hardness test with some type of sclerometer should be included in the functional characterisation of all engineered or grafted neocartilage.

Histogenesis and Morphology of periosteal sarcomas induced by FBJ virus in NIH Swiss mice.

FBJ virus was injected i.p. into 145 neonatal NIH Swiss [N:NIH(s)] mice. Eighty mice developed a total of 110 neoplasms by 5 months of age. The mean latent period of the tumors was 71 days (26 to 145) postinjection. The frequency of occurrence of neoplasms at different sites was: diaphragm, 45%; ribs, 14%; vertebrae, 14%; femora, 9%; pelvic bones, 5%; tibiae, 4%; sternebrae, 3%; and inguinal area, 7%. The neoplasms were characterized histologically by elongated or rounded cells associated with an abundant connective tissue stroma. Occasional areas of bone formation and apparent osteoid metaplasia were seen. Bone tumors appeared to arise from periosteal cells, to grow by expansion, and to invade locally, but they failed to metastasize. Neoplasms of the diaphragm originated in the central aponeurosis and appeared histologically similar to bone neoplasms. Histochemical studies demonstrated abundant alkaline phosphatase in tumor cells, and ultrastructural observations revealed subcellular characteristics of osteoblasts and chondroblasts. Tumors were readily transplantable and had histopathological characteristics similar to those of the primary viral-induced tumors. The results of this study indicate that the FBJ virus induces in NIH Swiss mice a unique type of chondroosseous neoplasm derived from periosteal cells which has a resemblance to human juxtacortical (parosteal) osteosarcoma.

[Osteosis due to primary hyperparathyroidism. The SEM ultrastructural features of the periosteal and endosteal surfaces].

The study of four cases of osteosis caused by primary hyperparathyroidism, tree female and one male, which have undergone surgery for pathological fractures in met-epiphysis bone, allows to analyze with the help of scanning electron microscope modifications occurring in periosteal and endosteal bone matrix. The periosteal surface appears abundantly furrowed by large and deep canals, irregularly joined together. Areas of resorption, these at rest and these of osteodeposition are distributed in changeable but regular way. The bone turnover of endosteal side is particularly accentuated. This surface contains the bone trabeculae residuals and is widely marked by deep Howship's lacunae, which show intense osteoclastic activity. It seem that osteocytes cells participate actively in the process of osteolysis, widening the lacunae and small canals which appear to be surrounded by calcospherites arranged in irregular way. Osteogenetic activity, with large areas of deposition, is very intense, as a defence attempt against osteolytic resorption process.

Periosteal Ewing's sarcoma.

Periosteal Ewing's sarcoma is an uncommon, but well documented origin of this malignant condition with radiographic signs, different from intramedullary growing tumours. Imaging modalities like CT or MRI supply proof of macroscopically intact endosteal cortical surface and free medullary cavity in long bones affected by this periosteal type of malignancy. Definite confirmation is valid after a careful microscopic investigation of the resected specimen. The prognosis of this type of Ewing's sarcoma may be more favourable than that of the central type. Early diagnosis and therapy are thus essential. A clinical survey of six observations is given.

[Use of a periosteal flap in the surgical management of rupture of the acromioclavicular joint capsule and ligament. Preliminary report].

Authors use in the treatment of acromioclavicular joint dislocations to increase the safety of the ligament sutures a periosteal flap, gained from the clavicle. The use of the periosteal flap to increase the strength of the acromioclavicular ligament sutures is described. In case of fixing the joint with a tension band the suspension of the cerclage on a screw for an easier removal is suggested.

[Periosteal reaction in periarteritis nodosa in children].

Bone involvement has exceptionally been reported in children with periarteritis nodosa. A 5-year old girl was admitted to hospital for fever and arthralgias. Three months later, myalgias and painful subcutaneous nodules developed on the legs and ankles. Skin biopsy yielded a diagnosis of periarteritis nodosa. X-ray films revealed a bilateral periosteal reaction with images of laminae in the tibia and fibula. After a 4-year remission under corticosteroid therapy, the periosteal reaction persisted.

Neochondrogenesis in free intraarticular periosteal autografts in an immobilized and paralyzed limb. An experimental investigation in the rabbit.

The purpose of this investigation was to determine whether neochondrogenesis can be induced in free intraarticular autografts of periosteum in the complete absence of motion. In 17 adolescent rabbits, a rectangular graft of periosteum was elevated from the medial aspect of each proximal tibia and folded back on itself so that its deep (cambium) layer was facing outward on both sides. The grafts were transplanted into both ipsilateral knee joints that had been paralyzed by section of the femoral and sciatic nerves, and a cast was applied to one hind limb to provide immobilization. The opposite knee joint of each animal was then placed in the continuous passive motion (CPM) apparatus. At the time of death (21 days postoperatively), some degree of neochondrogenesis was evident in 69% of the grafts in the group with casts and in 100% of the grafts in the CPM group. Hyaline cartilage was the predominant tissue in 13% of the grafts in the group with casts compared to 63% of the grafts in the CPM group. Although this investigation has confirmed the chondrogenic potential of free periosteal grafts in a synovial fluid environment (and the significantly stimulating effect of CPM), the results have also demonstrated that at least some hyaline cartilage can be formed by periosteal grafts even with paralysis of the limb plus immobilization of the joint (presumably complete immobilization). Thus, other factors capable of stimulating neochondrogenesis warrant investigation.

Electrically stimulated periosteal grafting in the rat.

Osteogenesis of the periosteum was examined in rats. The periosteum electrically stimulated for 6 days was grafted into the axillar muscle, and new bone tissue was found in 40 out of 44 animals (90.9%). Periosteum without stimulation and that with only 2 days of electrical stimulation did not generate new bone tissue. The periosteum electrically stimulated for 4 days did not show substantial new bone formation in the muscle. The periosteal tissue which was initially electrically stimulated for 6 days was definitely transformed into new bone tissue in the muscle. This shows that boneless bone grafting can be accomplished successfully in rats by electrically stimulating the periosteum before grafting. Periosteal grafting is considered to be potentially valuable as a boneless bone grafting technique.

[Idiopathic periostal hyperostosis with dysproteinemia (author's transl)].

The idiopathic periostal hyperostosis with dysproteinemia shows typical symptoms: acute onset with high fever and severe pain in the forearms and the praetibial area, periostal reaction along the ulnae and tibiae accompanied by hypalbuminemia and alpha2-globulin increase. The clinical entity has yet been described in only 2 cases. Our own case illustrates the longterm follow-up. The differential diagnosis especially of Caffey-Syndrom is discussed.

The influence of vascular and periosteal interferences on the histological structure of the growth plates of long bones.

Investigations have been carried out on the histological structure of the growth plates of the rabbit femur following interferences of the vascular blood supply in the metaphysial/diaphysial area and following 3 different types of periosteal division. Trepanation of the cortex had no observable effect on the growth plate. Following the other vascular interferences the reaction of the growth plates was characterised by a total or a partial thickening due to an accumulation of hypertrophic cells followed by a period of regeneration until 40 d p.o. Following periosteal intervention only small differences between operated and non-operated femur were observed. It was concluded that the fibrous periosteum, in contrast to the vascular supply of the metaphysial/diaphysial area plays a role in the local growth regulation of the epiphysial plate, probably by affecting the rate of mitosis of the germinal cells.

Periosteal osteosarcoma.

Periosteal osteosarcoma is a surface lesion without evidence of medullary involvement. This report extends the Mayo Clinic series of periosteal osteosarcoma cases from 11 to 22 cases. In a review of demographic information from our 22 cases and from 30 additional cases, referred only for pathologic diagnosis, the average age at the time of diagnosis in our series was 20.5 years. The proximal tibia was the most frequent site of tumor. Men and women were affected in approximately equal numbers. Limb pain and swelling were common complaints, as were findings of limb mass and tenderness. Excision of a tumor demands at least wide margins. When surgical margins were less than wide, there were higher rates of local tumor recurrence and tumor metastasis. A relatively high rate of tumor recurrence and metastasis occurred with femoral lesions despite wide excisional margins, suggesting that femoral lesions may need more aggressive surgical treatment.
