Periosteal resorption of finger phalanges: radial versus ulnar surfaces.

Measurement of periosteal resorption (PR) at the radial and ulnar surfaces of the second, third and fourth middle phalanges of one hand in 60 normals and 61 chronic renal failure (CRF) patients showed generally higher involvement at the radial than the ulnar surfaces; however, best diagnostic results were achieved when PR was measured at both radial and ulnar surfaces of the index finger only. With the quantitative method, 31 of 61 CRF patients showed changes, whereas only 22 were identified with the grading method.

Study of the periosteal and arachnoidal aspects of dura mater implanted surgically in the ventricular wall of the canine heart.

After surgical removal of a portion of the cardiac wall, homologous dura mater cardiac grafts were sutured to the margins of the incision in the sternocostal wall of the right ventricle of the canine heart and recovered after 1, 4, 6 and 8 weeks of implantation. Representative tissue specimens were processed for and studied by means of SEM and TEM. The primary objectives were to study morphological changes in the dura mater grafts used to repair the lesions or defects in the cardiac wall and to compare alterations in the periosteal and arachnoidal aspects of the dura mater grafts after being implanted for varying periods of time. After one week of implantation, an amorphous layer of fibrin was deposited on or near the luminal surface of the original dura mater grafts. At four weeks of grafts implantation, a 'remodeling' process was apparent below the luminal surface of the graft. Although a large accumulation of fibrin was still present at this time, there was also an increase in the number of cellular and fibrillar components within the implant. Large numbers of macrophages and active fibroblasts were visible at this time along with new collagen. At the sixth week of implantation, an abundance of active fibroblasts, the presence of normal collagen and a darkly staining material interpreted as recently synthesized connective tissue components, fibrin deposits and/or degenerating collagen were also observed. Phagocytosis of the remaining fibrin was noted during this period indicating a continuation of the remodeling process at the luminal surface. Finally, after eight weeks of implantation, it was revealed that the original densely woven and relatively acellular graft had become infiltrated with various blood cells and vascular channels.

Bone scintigraphy in evaluating the viability of composite bone grafts revascularized by microvascular anastomoses, conventional autogenous bone grafts, and free non-revascularized periosteal grafts.

We studied the value of bone scintigraphy in the assessment of anastomotic patency and bone-cell viability in free bone grafts revascularized by microvascular anastomoses in twenty-seven dogs. The dogs were divided into three different groups, and scintigraphy was carried out using technetium-labeled methylene diphosphonate in composite bone grafts revascularized by microvascular anastomoses, conventional autogenous bone grafts, and periosteal grafts placed in different recipient beds. The viability of the grafts was evaluated by histological examination and fluorescence microscopy after triple labeling with oxytetracycline on the first postoperative day, alizarin complexone on the fourth postoperative day, and DCAF on the eleventh postoperative day. A positive scintiscan within the first week following surgery indicated patent microvascular anastomoses, and histological study and fluorescence microscopy confirmed that bone throughout the graft was viable. A positive scintiscan one week after surgery or later does not necessarily indicate microvascular patency or bone-cell survival, because new bone formed by creeping substitution on the surface of a dead bone graft can result in this finding.

Osteolysis after rigid fixation. The possible role of periosteal neural mechanoreceptors in bone remodeling.

Rigid intramedullary fixation in the rat tibiofibular bone of a tibial fracture caused the development of nonunion in the associated fibular fracture, with marked osteolytic resorption of the fibular fragments. In contrast, with flexible fixation, the associated fibular fracture healed normally. The tibial fractures healed uneventfully in both cases. Histologic examinations showed that there exists a plexus of encapsulated nerve endings (Pacinian corpuscles) in the periosteum of the fibula, at the distal tibiofibular junction. The rat fibula forms a bony contact with the lower midshaft of the anteriorly curved tibia, acting as a supporting shaft. The periosteal neural mechanoreceptors probably sense the fibular loading when the tibia is bent during weight-bearing. Fibular resorption in rigid fixation could be attributed to the rigid intramedullary nail preventing tibial bending and loading of the receptor area. In other words the neural elements could detect the stress protection due to rigid fixation and coordinate the adverse remodeling process.

Radiologic and pathologic analysis of solitary bone lesions. Part II: periosteal reactions.

The activated periosteum has a deceptive anatomic constancy amidst change. The change involves the production of matrix and, in the process, proliferation and expenditure of cells. When the demand for a reaction is excessive, nearby extraperiosteal soft tissue serves as a ready source for additional modulating cells, just as it does for fracture callus. The configuration of a periosteal reaction is an index of the nature and intensity of the inciting process.

In vivo exposure to sodium fluoride does not modify the yield of viral tumour-induced periosteal bone nor of heterotopic bone induced by human tumour KB cells in mice.

In mice local or systemic administration of fluoride (5-25 mg NaF/kg body weight) during the proliferative phase of bone formation (up to 20 days) has no effect on the yield of bone formed either by local stimulation of periosteal membrane by Moloney sarcoma virus-induced tumour or on bone induced heterotopically by human KB cells. The lack of stimulatory activity of fluoride on rapidly induced osteogenesis in mice is in agreement with recent reports which show that fluoride is not a potent mitogen for human osteoblasts grown in vitro.

Racing performance after hemicircumferential periosteal transection for angular limb deformities in thoroughbreds: 199 cases (1987-1989).

Racing records of 199 Thoroughbred foals with angular limb deformities surgically treated by hemicircumferential periosteal transection and elevation (HCPT) from 1987 through 1989 (principals) were compared with records of their 1,017 siblings (controls) for starting status; 2-, 3-, and 4-year-old starts; earnings and earnings per start; and starts percentile ranking number (SPR). Principals had a slightly lower percentage of horses starting a race (45 vs 55%), fewer 2-year-old starts (1.06 vs 1.72), and lower SPR (33.49 vs 49.18), compared with those of controls (P < 0.05). Starting status was significantly (P < 0.05) affected by surgery and the horse's sex, but not by anatomic site treated. Fillies were 1.74 times less likely to start than were colts, regardless of surgery, whereas principal fillies were 2.63 times less likely to start than were control colts. Difference was not detected between principals and controls in 3- or 4-year-old starts; 2-, 3-, or 4-year-old earnings, or earnings per start. Horses treated with distal metacarpal/metatarsal HCPT had fewer 2-year-old starts (1.09 vs 2.19), but did not have a significantly different SPR or lower starting percentage, compared with values for controls. Horses treated with distal radial HCPT had lower starting percentage (48 vs 55%), fewer 2-year-old starts (1.22 vs 1.70), and lower SPR (32.53 vs 53.32), compared with those of controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Periosteal osteosarcoma. Review of 41 cases, 22 with long-term follow-up.

This study is based on 41 cases of parostesl (or juxta cortical) osteogenic sarcoma, which the authors prefer to define as periosteal osteosarcoma. The clinical features, radiological and histological characteristics are analysed. Treatment and prognosis are discussed. The treatment usually indicated is amputation, but in selected cases radical segmental resection is appropriate. The prognosis is comparatively favourable if the correct surgical treatment is carried out without delay.

Facial development in unilateral cleft lip and palate prior to the eruption of permanent incisors after primary bone grafting and periosteal flap surgery.

Roentgencephalometric studies were carried out at the age of five years in 27 boys with unilateral cleft lip and palate after primary bone grafting, as well as in 25 boys with the same type of cleft after primary periosteoplasty and in 27 normal boys who served as a group of controls. Both series with clefts differed from the group of controls by a reduced upper face height, maxillary dentoalveolar retroinclination, posterior position of the maxilla and by the shortening of mandibular body and ramus. There was a slight reduction of maxillary depth only in the series with bone grafts. The other skeletal deviations were secondary. The soft profile showed in both series with clefts a reduction of the upper lip height and of the nasal prominence. In patients with bone grafts was recorded in addition a reduced prominence of the upper lip. A comparison of both series with clefts disclosed that primary bone grafting reduced the vertical growth of the upper face and increased the dentoalveolar retroinclination of the maxilla resulting in a larger impairment of overjet and in a more marked retrocheilia. A better prominence of the nose in the series with periosteal flap surgery was produced by the primary reposition of the nasal septum, which was not performed during osteoplasty.

Vascularized iliac periosteal transfer for the treatment of avascular necrosis of the femoral head and a new evaluation grading system.

OBJECTIVE: To introduce the surgical technique and a new evaluation grading system and to report the results of the vascular iliac periosteal grafting for avascular necrosis of the femoral head. PATIENTS AND METHODS: From 1983 to 1994, a new technique was used to treat 75 hips of 60 patients with avascular necrosis (AVN) of the femoral head using the vascular iliac periosteum with deep iliac circumflex artery and vein pedicle. 52 patients (66 hips) were followed up for 3-11 years and all patients were evaluated clinically and roentgenographically according to the new evaluation grading system for AVN by the Chinese Society for Osteonecrosis. RESULTS: Preoperatively, the average AVN score was 57 pts., and all patients had significant pain and limp. Five hips were at Ficat/Arlet stage IV, 40 were at stage III, and 21 were at stage II. Postoperatively, the average AVN score was 83 pts., 47 hips were pain free, 13 had mild pain, and 6 had moderate pain. At the latest follow-up, according to the new evaluation grading system, 26 hips were graded as excellent, 32 hips as good, 5 hips as fair, and 3 hips as poor. CONCLUSION: It is one of the better alternatives that can prevent the necrotic femoral head from progressing to collapse and promote revascularization and new bone formation by a direct mechanism, and it is suitable for the treatment of AVN of the stage I to III.

Sepsis of the common digital extensor tendon sheath secondary to hemicircumferential periosteal transection in a foal.

A 4-month-old Quarter Horse was admitted for evaluation of infection that developed following bilateral hemicircumferential periosteal transection and elevation. Sepsis of the common digital extensor tendon sheath was diagnosed. Treatment included lavage of the tendon sheath, placement of an indwelling drain for lavage after surgery, establishment of drainage, and administration of antimicrobial and anti-inflammatory drugs. Three months after treatment, the foal was clinically normal.

[Repairing bone defect with autogenous periosteal pieces in coagulum: experimental study and clinical application].

A 1.5 cm-long bony defect was established in rabbits one each on both sides. The defected area was filled with coagulum of peripheral blood or bone marrow blood, then autogenous pieces of the periosteum was put in the coagulum on one side, while the other side was served as the control without periosteal autograft. The osteogenetic capacity of the periosteum and the influence of different blood coagulum were evaluated by means of X-ray film, histology, the contents of calcium and phosphate in new osteocytes in the defected area, bone tissue morphometry, and computer-assisted image analysis. The autograft of the periosteum had osteogenetic effect. Autologous bone marrow blood had potential osteogenetic capacity, which however, was weaker than that of the periosteum. Peripheral blood coagulum did not have any osteogenetic effect. We have successfully used the periosteum-bone marrow blood complex (bone marrow blood as a carrier) in 12 patients.

[Applied anatomy of osteo-periosteal flap pedicled with superior malleolar branch of anterior tibial artery].

In order to investigate the blood supply of osteo-periosteal flap of lateral inferior part of tibia, 40 lower limbs of adult cadavers were observed. The result showed that the superior malleolar branch was the biggest branch on the lateral inferior part of tibia and served as the main blood supply to the above area. It originated from the anterior tibial artery, 3.1 +/- 0.8 cm above the intermalleolar line. During its way to the anterior border of the tibia, it gave out the ascending and descending branches. The ascending branch was along the anterior border upward and anastomosed with the musculo-periosteol branch of the anterior tibial artery at the level of 6.3 +/- 1.3 cm above the intermalleolar line. The decending branch was anastomosed with the anterior medial malleolar artery. For the anastomosis between the superior malleolar branch with the peripheral vessels, the osteo-periosteol flap could be designed at the lateral side of the lower part of tibia in size of 8-10 cm x 4-6 cm. This was a new donor area of osteo-periosteol flap for repair of non-union of bone in lower end of tibia or arthrodesis of the ankle joint.
