Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

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...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

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 of the...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Reconstructive Surgery

Background:

  • Total elbow arthroplasty (TEA) is a relatively new procedure compared to hip or knee replacements.
  • Long-term outcome data for TEA is limited despite ongoing design evolution.
  • Elbow prostheses are categorized into unlinked, linked, and convertible designs.

Purpose of the Study:

  • To review the current state of unlinked and convertible total elbow prostheses.
  • To discuss the evolution and design principles of these specific TEA categories.
  • To identify gaps in long-term outcome data for unlinked and convertible TEA.

Main Methods:

  • Literature review of existing studies on total elbow arthroplasty.
  • Focus on unlinked and convertible prosthesis designs.
  • Analysis of available outcome data and design trends.

Main Results:

  • Unlinked and convertible prostheses represent key categories in TEA development.
  • Design advancements continue, but comprehensive long-term data is still scarce.
  • Understanding these designs is crucial for future improvements in elbow joint replacement.

Conclusions:

  • Further research is needed to establish long-term efficacy of unlinked and convertible TEA.
  • Continued innovation in TEA design is essential for improving patient outcomes.
  • This review provides a foundation for understanding current unlinked and convertible elbow replacement technologies.
