Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Bones of the Upper Limb: Humerus01:19

Bones 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...

Summary
This summary is machine-generated.

A rare case of a supernumerary clavicle in a 3-year-old boy was documented. This extra bone, shaped like an italic S, connected the jaw to the sternum and clavicle, impacting neck movement.

Area of Science:

  • Anatomy
  • Pediatric Surgery
  • Medical Imaging

Background:

  • Supernumerary clavicles are rare congenital anomalies.
  • This case presents a unique anatomical variation impacting a child's neck mobility.

Observation:

  • A 3-year-old male presented with congenital neck lateralization and limited neck flexion/extension.
  • 3D CT scan revealed an S-shaped bony structure articulating with the jaw, left sternum, and clavicle.

Findings:

  • Surgical removal of the anomalous bone was performed.
  • Pathology confirmed the excised tissue as osseous with joint surfaces and bone marrow, consistent with a supernumerary clavicle.

Implications:

  • This case highlights the importance of advanced imaging in diagnosing rare congenital anomalies.
  • Understanding such variations is crucial for surgical planning and improving patient outcomes in pediatric orthopedic cases.
