Morphometric, anatomic and radiographic study of bone of the pelvic limb of endangered Patagonian huemul deer (Hippocamelus bisulcus) / Estudio morfométrico, anatómico y radiográfico de los huesos del miembro pélvico del huemul patagónico en peligro de extinción (Hippocamelus bisulcus)

Currently, the Patagonian huemul (Hippocamelus bisulcus) is endangered. Anatomical studies focused on understanding the anatomy of the deer most threatened by extinction in South America is a challenge for anatomists, veterinarians and biologists. Research carried out for its conservation has focused mainly on its ecology and pathology, leaving gaps in anatomical knowledge, which is basic and important for a comprehensive understanding of this species. Gross anatomy and radiography of the skeleton of the pelvic limb was performed in three adult Patagonian huemul. Bone specimens of three skeletally mature Patagonian huemul deer were used for gross osteological and radiographic studies. This study was conducted to reveal the morphometric and morphological features of the ossa membri pelvini of the Patagonian huemul. The main findings suggest the presence of powerful extensor muscles in the coxofemoral, femorotibial and tarsal joints, useful during walking, jogging and propulsion in deer. In general, the MNF of Patagonian huemul differ in position with respect to domestic ungulates. In addition, the presence of a notch or obturator canal was observed, with variability in morphology and development among the specimens.

Actualmente, el Huemul Patagónico (Hippocamelus bisulcus) está en peligro de extinción. Los estudios morfológicos centrados en comprender su anatomía han sido un desafío para morfólogos, veterinarios y biólogos. Investigaciones enfocadas en su conservación, se han centrado principalmente en su ecología, patología y en la descripción de sus principales agentes infecciosos, dejando vacíos en el conocimiento anatómico básico, y por ende, su comprensión morfofisiológica. El objetivo de este estudio fue describir la anatomía, morfometría y radiología macroscópica normal y detallada del ossa membri pelvini en tres especímenes de Huemul Patagónico, incluida una interpretación funcional como referencia para uso clínico y conservacionista, investigación biomédica y fines de enseñanza. Los principales hallazgos sugieren la presencia de potentes músculos extensores en las articulaciones coxofemoral, femorotibial y tarsal, útiles durante la marcha, el trote y la propulsión en los ciervos. En general, los forámenes nutricios principales del Huemul patagónico difieren en posición con respecto a los ungulados domésticos. Además, se observó la presencia de una muesca o canal obturador, con variabilidad morfológica y de desarrollo entre los especímenes.

Age determination from pelvis A radiological study in Mumbai region.

The bones of human skeletons develop from separate ossification centers. From these centers ossification progresses till the bone is completely formed. These changes can be studied by means of X-rays and these changes are age related. It is therefore possible to determine the approximate age of an individual by radiological examination of bones till ossification is complete. This radiological study was carried out with the objective to assess the general skeletal maturity around crest of ilium and ischial tuberosity, of subjects in Mumbai region. 99 males between age group of 9-25 years and 76 females between age group of 3-23 years attending the outpatient department of this hospital were selected. Age confirmed from history and noting the birth dates from driving license, passport, rations card or voter’s card. The cases were selected after ruling out the nutritional, developmental, and endocrinal abnormality which affects the skeletal growth. Data analysis was done in P4 computer using HPSS software. At the end conclusions were drawn which are compared with available results of various previous studies

Analysis of variation of Han male adolescent bone development in Hainan, Henan and Zhejiang provinces / 法医学杂志

OBJECTIVE@#To study the difference of bone development of the Han male adolescents in Hainan, Henan and Zhejiang provinces.@*METHODS@#All radiographs including sternal end of clavicle, pelvis and six main bone joints taken from 877 Han male adolescents aged between 12.00 and 20.00 in Hainan, Henan and Zhejiang provinces were reviewed. Twenty-four indices of skeletal development were analyzed based on "The Grading Standards" of skeletal growth of teenagers and then the bone age were calculated using mathematical model functions. The ratios of the bone age and the chronological age were then analyzed by statistical software.@*RESULTS@#The development of Hainan male adolescents' skeleton were about 1.09 years and 1.26 years earlier than that in Henan and Zhejiang at the age group of 12.00-12.99 years. The development of Hainan male adolescents' skeleton were about 0.70 years and 1.38 years earlier than that in Henan and Zhejiang at the age group of 13.00-13.99 years, while the development of Henan male adolescents' skeleton were about 0.68 years earlier than that in Zhejiang in this age group. The development of Hainan male adolescents' skeleton were about 0.79 years later than that in Henan at the age group of 18.00-18.99 years. The development of Hainan male adolescents' skeleton were about 0.70 years and 0.95 years later than that in Henan and Zhejiang at the age group of 19.00-20.00 years.@*CONCLUSION@#There are significant differences in the skeleton development of Han male adolescents between the provinces of Hainan, Henan and Zhejiang. These results provide potential value for the practice of forensic medicine, anthropology and clinical medicine.

Original research paper radiological study of disappearance of tri-radiate cartilage in pelvic-bone in Gujarati population.

For medico-legal purposes evidence of age is very essential in various types of cases such as Identification, Consent, Rape, Attainment of Majority, and Eligibility for Employment, etc. Various work done on the study of age determination by the study of appearance of ossification centers and epiphyseal union of different bones in India as well as abroad indicate a reasonable variation. Majority of them conclude that, the ossification and epiphyseal union of a bone vary in different part of the world. To the best of our knowledge very little work has been done on the study of disappearance of tri-radiate cartilage out of various bony parts useful for age estimation. The present study comprising of 50 subjects ( male=35; female=15),was carried out during the period January 2000 to July 2001 at the Forensic Medicine department and Department of radiology, B.J. Medical College, Ahmedabad.

Management of injuries to the true pelvis. Are we up-to-date?

The pelvic fracture is common in the orthopedic practice. It could be associated with morbidity and mortality due to urologic and vascular complications, respectively. Here is a report of the incidence of the above mentioned complications of this fracture, showing our auxiliary diagnostic methods and the frequencies of the therapeutic approaches. The current literature developments were reviewed in order to know where we stand. To achieve our goals, the necessary data were collected retrospectively from files of 74 cases that were consecutively and randomly admitted to our hospital between Jan-2000 and May-2003. The diagnosis of, pelvic fracture and associated significant hemorrhage into the pelvic retroperitoneal space is totally clinical in our practice and its management is known to be a difficult task surgically. The current literature developments in the diagnosis and management of this problem has been discussed and, in this regard, we found that our approaches are not up-to-date. But, regarding the diagnosis and management of bladder and urethral injuries, we can say that we are up-to-date. A study of the outcome of these injuries has been recommended
