Myocardial bridges.

Recently, many cases of sudden death on strenuous exercise attributed to muscular bridges on the coronary arteries have been reported in the literature. The incidence of such bridges, pooling all reports, is 5.4-85.7% of autopsies. In the present study, 30 hearts from postmortems and 76 hearts from departmental collections from embalmed cadavers (making a total of 106 hearts) were studied. Fifteen hearts (14.2%) showed muscular bridges. The length of the bridges varied from 4mm to 40mm, the majority being 10-19mm in length. Only two arteries viz, the left anterior descending artery and the left diagonal artery showed muscular bridges.

Position of the axillary nerve in the deltoid muscle.

The relationship of the anterior branch of the axillary nerve to the deltoid muscle was studied on both sides in 66 adult cadavers. The nerve runs a course on the deep surface of the deltoid muscle about 2.2 cm above the midpoint on the vertical plane of the muscle.

The scalene tubercle.

One hundred and thirty right and 114 left first ribs from a random collection have been studied for the characters of the scalene tubercle and the related structures. The tubercle is not always present but the muscular impression for the insertion of the scalenus anterior muscle on the superior surface of the first rib is almost constant and it generally extends upto the medial third of this surface. The arterial groove, generally shallow, lies behind the tubercle or the muscular impression and generally extends only upto the medial 2/3 of the superior surface. Likewise, the venous groove, mostly shallow, lies in front of the tubercle or the muscular impression and extends, generally, only upto the medial 2/3 of the surface. Normally, there is no separate groove for the lower trunk of the brachial plexus.

The groove in the lateral wall of the human orbit.

The orbital groove, the groove for the orbital branch of the middle meningeal artery, the meningo-orbital foramen and the foramen spinosum have been studied in 100 human skulls. The orbital groove is present in about 30% of skulls.

Surface area of the atlanto-occipital articulations.

The surface areas of the occipital condyles of 101 skulls and of the superior articular facets of 103 atlases have been measured to ascertain bilateral asymmetry and dominance. The atlases show a tendency to have larger facets and the occipital bones tend to have larger condyles on the right side.

The soleal line.

The soleal line in 167 left and 163 right tibiae has been studied. The line often does not follow the textbook description. It commences well below the fibular facet and ends well down nearer the middle of the bone on the medial border. It generally shows mixed characters of a line, a wide line, a ridge, or a groove. The line is frequently absent in the upper third. In the middle third, it is seen as a wide or as a ridge varying from 1 to 2 mm in height. In the lower third the line presents itself as a ridge. In the middle and lower thirds, the line is often seen as a depression varying from 1 to 2 mm in depth. The line shows a left-sided dominance.

Diplopodia with double fibula and agenesis of tibia. A case report.

A 14-year-old girl with a congenitally deformed and shortened right leg and foot is described. The patient could not bear weight on the deformed limb and had to hop on the left leg. The deformed foot faced backwards and had nine toes. The right leg was shorter than the left by 26 centimetres. Radiologically, the lower end of the right femur was ill-developed and there was no knee joint. There were two fibulae and the tibia and the patella were absent. A through-knee disarticulation was done and a prosthesis fitted later. The amputated leg and foot were dissected. Many of the muscles in the leg and foot were duplicated. There were two calcanei, one talus, one navicular, two cuboids and four cuneiforms. Ther were nine metatarsals, and all the toes had three phalanges except for one which had two.

Diaphysial nutrient foramina in human phalanges.

1770 phalanges of the hand and 660 phalanges of the foot, of unknown sex, were studied to determine the number, position and direction of the nutrient foramina. It was found that, in general, these bones had one nutrient foramen in the middle third of the shaft. The proximal phalanges of the fingers often showed double foramina. Most of the foramina were situated on the border between the palmar/plantar and dorsal surfaces. The distal phalanges of the toes, and particularly of the great toe, may have a nutrient foramen on the dorsal surface. In the intermediate phalanges of the toes it is not possible to identify the nutrient foramen with certainty. All the foramina were directed away from the growing end.

Diaphysial nutrient foramina in human metacarpals and metatarsals.

728 metacarpals and 691 metatarsals of unknown sex, and 120 metacarpals and metatarsals, each of known sex, were studied for the number, position, direction and symmetry of the diaphysial nutrient foramina. It was found that, in general, these bones had one nutrient foramen which was situated in the middle third of the shaft (over 90%). Few bones had no foramina and some had two. In the first and second metacarpals the foramina were mostly situated on the medial surface, and in the other metacarpals mostly on the lateral surface; whereas in the first three metatarsals the foramina were mostly situated on the lateral surface and in the remaining metatarsals mostly on the medial surface. There was a good deal of bilateral symmetry in the foramina. Without any exception, the foramina were directed away from the growing end. The various theories put forward to account for the direction of the nutrient foramina have been considered. The findings favour the 'growing-end' theory.
