Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.8K
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

3.6K
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

13.5K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.5K
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...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

9.6K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

14.6K
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...

Summary
This summary is machine-generated.

Osseous scaphotrapezial coalition, a rare hand condition, is often found incidentally without reported pain. This isolated fusion challenges existing theories on carpal coalition development.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Anatomy

Background:

  • Carpal coalition, the fusion of two or more carpal bones, is typically associated with congenital anomalies or acquired insults.
  • Proximal and distal carpal row fusions are commonly observed, often linked to genetic syndromes or trauma.

Purpose of the Study:

  • To investigate the characteristics of isolated osseous scaphotrapezial coalition.
  • To evaluate the clinical presentation and implications of this rare carpal anomaly.

Main Methods:

  • Literature review of reported cases of scaphotrapezial coalition.
  • Analysis of diagnostic findings and clinical outcomes.

Main Results:

  • Osseous scaphotrapezial coalition is an exceptionally rare form of carpal fusion.
  • Cases are frequently discovered incidentally, with no documented instances of pain or functional limitation.

Conclusions:

  • Isolated scaphotrapezial coalition questions the established understanding that carpal fusions are solely acquired or part of congenital syndromes.
  • This finding suggests alternative etiologies for carpal coalition may exist.
