Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.2K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.2K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Ankle Joint01:10

Ankle Joint

1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

3.2K
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...

Bone Disorders01:29

Bone Disorders

3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

3.4K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Foot and Ankle Surgery

Background:

  • Accessory navicular bones (os naviculare) are developmental anomalies.
  • They can cause symptomatic pain and foot deformity.
  • Literature on managing symptomatic cases is limited.

Observation:

  • A nine-year-old female presented with medial foot pain.
  • Initial imaging revealed a single accessory navicular bone.
  • Conservative treatment (casting) failed to resolve symptoms.

Findings:

  • Surgical excision revealed two separate accessory navicular bones, a novel finding.
  • This configuration is not currently classified.
  • Post-operative recovery was successful.

Implications:

  • This case demonstrates successful treatment of two accessory navicular bones using standard protocols for a single bone.
  • It suggests current management strategies may be effective for rare anatomical variations.
  • Further research into classification and management of multiple accessory navicular bones is warranted.
