Summary
The supratrochlear foramen, an opening in the humerus bone, was present in 28% of South Indian adult humeri studied. Researchers also analyzed its dimensions and variations, noting translucent septa in most cases.
Area of Science:
- Anatomy
- Anthropology
- Orthopedics
Background:
- The supratrochlear foramen is a common anatomical variation in the distal humerus.
- Understanding its prevalence and morphology is crucial for anthropological and clinical studies.
Purpose of the Study:
- To investigate the prevalence and dimensions of the supratrochlear foramen in South Indian adult humeri.
- To analyze associated septal variations (translucent or opaque).
- To compare findings with other racial groups and discuss evolutionary and clinical significance.
Main Methods:
- Examination of 150 dry adult humeri from South Indian individuals.
- Measurement of supratrochlear foramen dimensions (transverse and vertical diameters).
- Observation and categorization of septal opacity or translucency.
Main Results:
- A supratrochlear foramen was identified in 28% of the humeri, with near-equal prevalence on the right (27.9%) and left (27.8%) sides.
- The average dimensions of the foramina were 6.92 mm (transverse) and 4.64 mm (vertical), predominantly oval in shape.
- Translucent septa were observed in 66% of the bones, while opaque septa were found in 6%.
Conclusions:
- The study provides valuable data on the supratrochlear foramen in a South Indian population.
- Findings highlight the importance of considering this anatomical variation in orthopedic procedures and evolutionary studies.
- Prevalence and morphological characteristics show potential for population-specific analysis.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:16Muscles that Move the Forearm
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
