Purpose:
The study was undertaken to make a qualitative and quantitative assessment of unnamed foramen and tunnels in adult human scapulae with aid of plain and contrast radiographs.
Materials And Methods:
A total of 120 dry bones, 60 each of the right and the left side were included in the study. Distribution of these foramina and tunnels was noted for their number, side, location, course and communication. Their morphometry was done using Vernier's caliper.
Results:
Incidence of scapular foramina was 7.5% (R > L), whereas scapular tunnels were seen in 15.8% cases. Incidence of the sinuous, curved, and straight tunnels was found to be 50, 39, and 10.7% respectively. Left-sided tunnels were longer than the right ones. Plain and contrast radiographs were taken to confirm the findings.
Conclusion:
Anatomy literature describes only two scapular foramina, namely, nutrient foramen and suprascapular foramen/notch in a great zeal; occurrence of such anonymous foramina is hardly discussed. Through this study, there is an endeavor towards unfolding the mystery of scapular foramina in terms of their morphometry and distribution, the knowledge of which will aid clinicians, forensic experts, and surgeons in better diagnosis and management of clinical cases.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Cranial Bones: Lateral View
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...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
