“…In this study using freshly obtained cartilage tissue from the base of ear showed to have enough tough texture to be rolled and fill the gap without having any tendency to slip out. As per expected no local reaction was seen during first two weeks in both groups but sonographically sprouting small blood vessels network in Group II at end of two weeks in Group II with radiographic findings of intercortical callus formation within 30 days were good indication for local reaction of cartilage graft to act as stimulator to provide suitable bed for blood vessels penetration as compared to Group I (Graf et al, 1988;Hamanishi et al, 1994;Mende et al, 1986;Moss and Mowatt, 1983;Williamson et al, 1991) The ossification radiographically and pathologically being reported (Haktanir et al, 2005) in diced cartilage grafts used in cranial defects in rabbits. Findings of this study confirmed biological activity of cartilage despite of having self-blood vessels limitation.…”

Abstract:We would like to thank to the Faculty of Specialized Veterinary Sciences research council. Science and Research Branch of Islamic Azad University, Punak Tehran for approval and financial support to finish this project. Problems statement: The purpose of this research was to determine the biological effect of cartilage graft as a bone defect filler and osteogenetic stimulation to speed up bone healing too. Approach: Sixteen adult male New Zealand white rabbits having body weight ranged from 3.0-3.5 Kg. Under general anesthesia, a segmental full thickness bone defect of 10 mm in length was created in the middle of the right radial shaft in all rabbits. They were divided into two groups of 6 rabbits each. Group I was considered as control and the fractured site was fixed using finger bone plate with 4 screws, whereas the ear cartilage of 1×1 cm graft was used to fill the gap after fracture fixation in Group II. Rabbits in two groups were subdivided into 2 subgroups of 1 and 2 months duration with 4 rabbits in each. Radiography and two dimensional and color Doppler sonography were done before and after creating defects and on 15, 30 and 60 days to evaluate local reaction as far as new blood vessels network and callus formation are concerned. Results: On the radiographs during the whole process, bone repair in Group I was not as perfect as those in Group II samples and trace of internal callus filled the gap incompletely in 60 days in Group I, whereas in Group II internal callus almost was formed on 30 days and in addition intercortical callus was seen supporting to cover and filled the gap completely in this group. Sonographic findings confirmed the protrusion of newly formed blood vascular network in 30 days in Group I and from 15 days in Group II and remarkably increased till end of observation period. Conclusion: Cartilage graft is suitable alternative bone filler and radiography and sonography are reliable techniques to trace local reaction at proper time.

“…Due to the ultrasound frequencies used clinically, only bone surfaces and not the whole cortex or spongiosa can be visualized in intact bone ( Fig. 1) [2,7,10]. A few publications have reported on the application and limitation of ultrasound in diagnosing mandibular fractures [1,10].…”

The aim of this study was to analyse the applications and limitations of B-scan ultrasonography for diagnosing fractures of the mandibular condyle and ramus. Thirty-two patients with 39 radiologically proven fractures of the mandibular condyle and ramus were included in the study. The patients were examined with a 7.5 MHz small-part applicator. Five patients without fractures of the facial skeleton acted as controls. Normal sonoanatomical findings had been obtained for patients without mandibular fractures. B-scan ultrasonography enabled the experienced examiner to identify dislocated fractures of the mandibular ramus and the articular process in 67% of the fractures. The main disadvantage of ultrasonography was the inability of this technique to identify non-dislocated fractures. Because of its low sensitivity and specificity, B-scan ultrasonography does not provide an alternative to X-ray diagnosis of mandibular condyle and ramus fractures.

“…7 Although sonography is not the method of choice for the detection of bone fractures, sonographic examination of the bone contour for fracture may be worthwhile when painful swelling adjacent to the bone is present. 8 Bone is a natural obstacle to the transmission of sound at high frequency. The large difference in acoustic impedance between soft tissue and bone results in the formation of a very strong acoustic interface at their junction.…”

Purpose The purpose of this retrospective study was to determine whether high‐resolution sonography can aid in the diagnosis of radiographically occult fractures in the foot and ankle. Methods High‐resolution sonography with a 10‐MHz linear‐array transducer was performed in 268 patients with foot and ankle injuries whose initial plain x‐ray films were negative for fracture. Results Twenty‐four patients had occult fractures demonstrated by sonography. On sonography, the occult fractures appeared as a discontinuity of cortex echogenicity. The fractures were found at the calcaneus (n = 8), metatarsus (n = 6), talus (n = 3), navicular bone (n = 3), cuboid bone (n = 2), cuneiform bone (n = 1), and lateral malleolus (n = 1). Review of the patients' radiographs revealed tiny fractures at the sonographically identified locations in 2 patients. The first 5 patients underwent bone scans, which confirmed the presence of the fractures. The first 11 patients received follow‐up sonographic examination 6 weeks after diagnosis; in all 11, an echogenic line over the previous fracture site, presumably representing callus formation, was noted. Conclusions Sonography—a readily available, noninvasive imaging technique—can provide important information about soft tissue injuries and cortical discontinuities in the foot and ankle area. Using this procedure, occult fractures can be identified and delineated, and costly procedures such as MRI can be avoided. © 1999 John Wiley & Sons, Inc. J Clin Ultrasound 27:421–425, 1999.
