We analyzed 34 cases of large bone defect caused by trauma, infection and tumor resection from July, 1979 to June, 1985. The bony defect were restored by vascularized fibular graft or vascularized fibular transposition. 22 cases were the traumatic segmental loss and 7 cases were infected ones and 5 cases were the loss following tumor resection. Vascularized fibular graft was performed in 19 cases and vascularized fibular transposition was performed in 15 cases. The 33 cases(97%) of 34 cases had obtained sound bony union and average union time had been 18.6 weeks. Even local infection in the bone, vascularized fibular graft or transposition can be performed. Grafted or transposed fibula had been hypertrophied about 1.2 times in anteroposterior and lateral film which had been measured in the center of the fibula. The most common complication was the clawing of first or second toe. If the ipsilateral fibula is intact, the vascularized fibular transposition is better and if not, vascularized fibular graft is preferred. Operation using the vascularized fibula is a excellent method for the restoration of large bone defect in long bone.

PURPOSE: Unstable distal clavicle fractures should be treated surgically but may be difficult in firm fixation because of small distal fragment. Although a variety of fixation methods have been currently used, none of the methods seem to be firm fixation and little pain. We present a new technique using a spring plate which was modified from one third tubular plate and report the early results. MATERIALS AND METHODS: Modified spring plate was made from one third tubular plate and the distal hole of the plate was cutting and sharpened by rasp. The sharp edge was bent just like an animal claw (C shape). Between May 2007 and June 2009, a total of six patients with distal clavicle fracture were treated using modified spring plate. A sling was applied in the immediate post operative period for six weeks and exercises were started immediately. RESULTS: Union was achieved in all cases with excellent results without complication (mean Constant score, 96). All patients had returned to ordinary daily activities but mild limitation of abduction (150 degrees ) by seven weeks after surgery. After six months, the plate was removed. CONCLUSION: The modified spring plate has provided stable fixation for unstable distal clavicle fixation without disturbance to the acromioclavicular joint, subacromial space, or rotator cuff.

This study aimed to compare thickness of the capsule, corium, and soft tissues measured ultrasonographically and macroscopically in selected regions of bovine claws. A hundred and twenty claws (n = 120) of 15 healthy Holstein bovines were obtained. After cleaning the claws, ultrasonographic measurement of the capsule, corium, and soft tissues was performed while submerging the claws in a water bath. Macroscopic measurements were taken after cutting of the claws axially. These values were compared statistically. According to the macroscopic measurements, the mean thickness +/- standard deviation (SD) of the capsule for dorsal wall and sole was 6.2 +/- 0.1 and 9.5 +/- 0.4 mm, respectively. The thickness of the corium and soft tissues for dorsal wall and sole was 4.5 +/- 0.1 and 5.3 +/- 0.1 mm, respectively. Ultrasonographically, the mean thickness +/- SD of the capsule for dorsal wall and sole was 4.7 +/- 0.1 and 7.8 +/- 0.3 mm, respectively. The thickness of the corium and soft tissues for dorsal wall and sole was 4.3 +/- 0.1 and 5.9 +/- 0.2 mm, respectively. Findings demonstrated that ultrasonography can be reliably to measure of the thickness of the hoof capsule, corium, and soft tissue in bovine claw.

The pancreas is a mixed exocrine and endocrine gland involved in the control of many homeostatic functions.During embryogenesis,the pancreas arises from dorsal and ventral evaginations of the foregut,which subse- quently fuse into a single organ.The characterization of early genes expressed in the developing pancreas is critical to understand its specification and differentiation.Pdx1 is one of the earliest markers of pancreatic development and a key molecule in its development.Sox proteins form a large class of transcriptional regulators implicated in the control of a variety of developmental processes.One member of this family,Sox9,is expressed in the developing pancreas, but little is known about the function of Sox9 in the developing pancreas.We further investigated Sox9 function during pancreatic development in Xenopus .Using a hormone-inducible inhibitory mutant of Sox9 ,we found that Pdx1 expres- sion was reduced in the ventral pancreatic buds in Sox9-depleted embryos.We suggest that Sox9 gene expression may be involved in pancreatic development in Xenopus.

This investigation was designed to analyze the degree of dental compensation according to horizontal components of craniofacial skeleton and to investigate correlation between dental compensation and craniofacial pattern in skeletal class III malocclusion. The material selected for this study consisted of standard lateral cephalogram of 59 subjects in normal occlusion group, 91 subjects in mild skeletal class III malocclusion group and 58 subjects in severe skeletal class III malocclusion group. The mild skeletal class III malocclusion group was divided into two groups, one was class III malocclusion without anterior crossbite group and the other was class III malocclusion with anterior crossbite group. The data were analyzed by Quick-ceph image program. The results were as follows. 1. Mild skeletal class III malocclusion without anterior crossbite group showed the most labial inclination of upper incisors, followed by severe skeletal class III malocclusion group and mild skeletal class III malocclusion with anterior crossbite group, the Latter showing the least. The amount of lingual inclination of lower incisors was the largest in severe skeletal class III malocclusion group, and there was no statistically significant difference between mild skeletal claw III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior crossbite group. 2. There were little differences in vertical skeletal structure between mild skeletal class III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior cwssbite group, they showed statistically significant differences in the upper incisors measurements. 3. The measurements of lower incisors in mild skeletal class III malocclusion without anterior crossbite group and upper incisors in mild skeletal class III malocclusion with anterior crossbite group represented a high correlation with skeletal structure. Especially, deltaIMPA and deltaFMIA of lower incisor measurements, and deltaU1-FR deltaUi-SN of upper incisor measurements showed high correlation with skeletal structure in each group. 4. deltaIMPA and deltaFMIA of lower incisor measurements showed high correlation with skeletal structure in all groups. deltaUI-FH, deltaU1-SN and Ui-facial plane(mm) of upper incisor measurements represented higher correlation with skeletal structure than any other upper incisor measurements.

Based on a study of 140 caaes of spondyloses with chronic backache, the sites and types of spurs and underlying congenital anomalies were analized. The following results were obtained. The most common sites of spurs were expected to be between L5 & S1 but contrary to the expectation, these were found most commonly between L4 & L5 and between L3 & L4. The reason for the preponderance of the spurs between L4 & L5 and L3 & L4 were not immediately available. All spurs represent claw type except in 4 cases which resemble traction spurs of McNab but without segamental instability. There were 39 cases of congenital anomalies. 28 of them were of tropism. Thus we conclude that the most common congenital anomaly associated with spondylosis is tropism.

Lichen nitidus, characterized by its typical clinical and histopathologic findings, is an uncomrnon chronic dermatosis of unknowned etiology. The distribution of this disease is most often localized, but in some cases it may becorne generalized. Some authors suggested that lichen nitidus is a variant of lichen planus in terms of its coincidence, ultrastructural and immunophenot,ypic studies. We report herein a case of lichen nitidus which presents dark brown linear, grouped, or confluent papules on the face, cheat, and upper extremities, accompanying with the histopathologic findings of pigmentary incontirence in the portion of claw clutching a ball appearance. This report suggests that lichen nitidus shows hyperpigmentation clinically and could be one of the dermatoses which exhibit pigmentavy incontinence in a histopathologic study.

Appropriate hoof preparation and symmetry are linked to the well-being of the horse. Previous studies have shown the efficacy of pressure plates (PPs) in delivering objective biomechanical analysis. We aimed to assess the effect of hoof trimming on hoof biomechanics using a PP. Nine clinically sound Arabian horses were walked across a PP while foot strike was recorded by a digital camera. Kinetic and kinematic parameters were recorded before and after trimming. Changes were considered significant when p < 0.05. Vertical force (p = 0.026) and contact pressure (p = 0.006) increased after trimming. Stance-phase duration (p = 0.006), swing-phase duration (p = 0.023), and gait-cycle duration (p = 0.007) decreased significantly post-trimming. The observed changes in kinetic and kinematic parameters were related to hoof trimming. The reported results underline the importance of farriery practice and its effect on hoof biomechanics, which should be considered by both farriers and veterinarians.

Syringomyelia was described by Etienne et al in 1954 and was named by Ollivier in 1827 by reason of the pathologic cavitation of cord. Also it is considered a very chronic and irregulary progressive disease of the spinal cord of unknown cause which has predilection for the cervical and lumbar enlargements. The patient of 19 years old male had been suffered from the painless, severe swelling and instability of right elbow after trauma on right elbow, aud had complained of the sensory and temperature dissociation, muscle weakness with clawing hand in right upper extremity and scoliosis of mild degree. These symptoms and findings were same as those of the classic syringomyelia. Therefore the syningomyelia which is relatively rare in incidence will be reviewed by this report with the references.

We report a case of epidermal nevus syndrome. The patient was a 26-year-old female who had numerous linear verrucous plaques on her neck, upper back and anterior chest. Biopsy of these lesions revealed epidermal hyperkeratosis, acanthosis and papillomatosis. Variable sized cafe-au-lait spots were scattered around the verrucous nevi. The other associated findings were claw hand deformity and epilepsy. Electroencephalogram showed very irregular, random and slow waves confined to the right temporooccipital area.
