The trimalleolar fracture involves the lateral, medial, and posterior malleoli of the ankle, often destabilizing the joint and impairing mobility. These fractures usually occur due to high-energy trauma, such as falls or sports injuries, and commonly require open reduction and View Diagram Trimalleolar Fracture of the Ankle Joint
The sacrum is a triangular bone formed from fused vertebrae, articulating with the pelvis and supporting weight transfer to the lower limbs. Knowledge of sacral anatomy is essential for orthopedic surgeons, obstetricians, and medical students in spinal surgery, pelvic procedures, View Diagram Overview of the Sacrum
Radiographs of scoliosis reveal abnormal lateral curvature of the spine with vertebral rotation, commonly in thoracic or thoracolumbar regions. Severity is measured using the Cobb angle, guiding treatment decisions. Knowledge of scoliosis radiographic features is essential for orthopedic surgeons, radiologists, View Diagram Radiograph of Scoliosis of the Spine
Calcaneal fractures are visible on radiographs as disruption of the heel bone, often associated with axial loading injuries. Knowledge of fracture patterns is essential for orthopedic surgeons, radiologists, and medical students in managing conservative or surgical treatment.

The facial skeleton is composed of multiple bones including the maxilla, mandible, zygomatic, nasal, and lacrimal bones, providing structure and support for the face. These bones contribute to chewing, breathing, vision, and expression. Knowledge of facial bone anatomy is crucial View Diagram Bones of the Facial Skeleton
The median nerve in the hand gives off branches including the recurrent branch to the thenar muscles and digital cutaneous branches to the fingers. These branches provide motor and sensory innervation essential for hand function, grip, and dexterity. Knowledge of View Diagram Branches of the Median Nerve in the Hand
The superficial temporal artery is a terminal branch of the external carotid artery, giving off frontal and parietal branches that supply the scalp, temple, and lateral face. Knowledge of its course and branches is essential for surgeons, dermatologists, and medical View Diagram Branches of the Superficial Temporal Artery
Major fontanelles in the infant skull include the anterior and posterior fontanelles. The anterior fontanelle, located at the junction of the coronal and sagittal sutures, is diamond-shaped and closes around 18 months. The posterior fontanelle lies at the junction of View Diagram Major Fontanelles and Sutures of the Skull
The membranous labyrinth is a fluid-filled structure within the bony labyrinth of the inner ear. It contains endolymph and includes the cochlear duct, utricle, saccule, and semicircular ducts. These structures are responsible for hearing and balance. Damage may result in View Diagram The Membranous Labyrinth
Blowout fractures of the orbital floor involve disruption of the inferior orbital wall, often due to blunt trauma to the eye. CT imaging identifies the fracture, orbital content herniation, and potential muscle entrapment, which can cause diplopia or restricted eye View Diagram CT Scan of a Blowout Fracture of the Inferior Wall
The lateral compartment of the leg contains the fibularis longus and brevis muscles, responsible for eversion and plantarflexion of the foot. These muscles are innervated by the superficial fibular nerve and receive blood supply from branches of the fibular artery. View Diagram Lateral Compartment of the Leg
The anterior view of the frontal bone forms the forehead and part of the superior orbital region. This anatomy diagram of the anatomy of the frontal bone anterior illustrates features such as the frontal squama, supraorbital margins, and glabella. It View Diagram Anatomy of the Frontal Bone Anterior
The retromandibular vein courses through the parotid gland and drains into the external jugular vein or common facial vein. Its tributaries include the superficial temporal and maxillary veins. Knowledge of the retromandibular vein anatomy is essential for surgeons, radiologists, and View Diagram Retromandibular Vein Course and Tributaries
A typical rib consists of a head, neck, tubercle, and body. The head articulates with the thoracic vertebrae at costovertebral joints, while the tubercle connects with the transverse process. The shaft curves anteriorly and inferiorly, forming the costal angle before View Diagram Structure of a Typical Rib
Coronal sections of the ear show mastoid air cells within the temporal bone, which communicate with the middle ear and help in sound resonance and pressure regulation. Knowledge of mastoid anatomy is essential for ENT surgeons, radiologists, and medical students View Diagram Coronal Section of the Ear Showing the Mastoid Air Cells
The wrist joint involves articulation between the distal radius, articular disc, and proximal carpal bones. This anatomy diagram of the articulating surfaces of the wrist joint illustrates the scaphoid, lunate, and triquetrum articulating with the radius. It highlights the role View Diagram Articulating Surfaces of the Wrist Joint Radius Articular Disk and Carpal Bones
The mastoid fossa is a depression within the temporal bone that houses the mastoid air cells and provides attachment for the sternocleidomastoid and other muscles. Its air cells communicate with the middle ear, playing a role in pressure regulation. Knowledge View Diagram Mastoid Fossa Overview
