OBJECTIVE: The tendons of the extensor carpi radialis longus and brevis muscles are quite useful in tendon transfer, such as in correction of finger clawing and restoration of thumb opposition. Knowledge of additional radial wrist extensor muscle bellies with independent tendons is useful in the above-mentioned surgical procedures. METHODS: The skin, subcutaneous tissue, and antebrachial fascia of 48 (24 on the right side and 24 on left side) male upper limb forearms were dissected. The following aspects were then analyzed: (a) the presence of additional muscle bellies of radial wrist extensors, (b) the origin and insertion of the additional muscle, and (c) measurements of the muscle bellies and their tendons. RESULTS: Five out of 48 upper limbs (10.41%) had additional radial wrist extensors; this occurred in 3 out of 24 left upper limbs (12.5%) and 2 out of 24 right upper limbs (8.3%). In one of the right upper limbs, two additional muscles were found. The length and width of each additional muscle belly and its tendon ranged between 2 - 15cm by 0.35 - 6.4cm and 2.8 - 20.8cm by 0.2 0.5cm, respectively. The additional radial wrist extensor tendons in our study basically originated either from the extensor carpi radialis longus or brevis muscles and were inserted at the base of the 2nd or 3rd metacarpal bone. CONCLUSION: The present study will inform surgeons about the different varieties of additional radial wrist extensors and the frequency of their occurrence.

To evaluate the mandibular angle and to analyze the relationship of the angle and height & breadth of the ramus of the mandible to the gender, so as to study its role in the anthropological diagnosis. The angle, height and breadth of the ramus of adult dry human mandibles of both sexes were measured using a goniometer. The values obtained were analyzed statistically. The present study showed a statistically significant difference in the mandibular angle as well as height of the ramus between both the sexes. The mean mandibular angle of Indian population when compared to that of European population was found to be lower by 9 degrees. The findings of this study might be useful in providing anthropological data that can also be used in dental and medical practice. However, the Indian mandible can be used for sexual dimorphism as is usual in anthropological work; it appears to possess important unfavourable anatomic factors that may predispose the individuals to difficult laryngoscopy or intubation

Para estudiar su rol en el diagnóstico antropológico, evaluamos el ángulo de la mandíbula y analizamos las relaciones de este ángulo con la altura y ancho de la rama de la mandíbula, en ambos sexos. Con un goniómetro, en huesos secos, fue obtenido el ángulo, alto y ancho de las mandíbulas humanas. Los valores obtenidos fueron analizados estadísticamente. El estudio mostró diferencias estadísticamente significativas en el ángulo mandibular como también en la altura de la rama de la mandíbula, en ambos sexos. La media del ángulo mandibular de la población hindú fue 9 grados menor, comparada con la población europea. Los resultados de este estudio pueden ser útiles al aportar datos antropológicos utilizados en las prácticas médica y dental. Por otra parte, la mandíbula de los hindúes puede ser usada como dimorfismo sexual como es usual en trabajos antropológicos. Parece haber factores anatómicos desfavorabes importantes que pueden predisponer a los individuos a laringoscopías difíciles o intubación

Tibial collateral ligament by virtue of its length, composite attachments, and biomechanical exertions is more prone to lesions. A systematic analysis of the dimensions and variations of this ligament has been presented in this article. With the decrease emphasis on anatomy as a preclinical subject and recent successful moves to curtail total teaching hours for dissection, coupled with the increasing shortage of cadavers, data of this nature will in our opinion becomes scarce progressively. With these factors in context, and attempt is made to record the gross morphological features of the ligament from a series of dissections

El ligamento colateral tibial, por virtud de su longitud, inserciones y esfuerzos biomecánicos, está más propenso a lesiones. Un análisis sistemático de las dimensiones y variaciones de este ligamento se presentan en este artículo. El decrecimiento del énfasis de la Anatomía como un ramo preclínico y la falta de cadáveres nos movieron a disminuir las horas de disección. Así, en nuestra opinión, los datos anatómicos son progresivamente más escasos. Con el propósito de registrar las características morfológicas macroscópicas del ligamento colateral tibial, realizamos una serie de disecciones
