Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

8.9K
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...

Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Surgery
  • Arthritis Treatment

Background:

  • Debilitating painful arthritis is a common indication for radiocarpal fusion.
  • The primary goal is to fuse diseased wrist joints while preserving motion in healthy articulations.
  • Radiocarpal fusions can be radiolunate, radioscapholunate, or total wrist fusions depending on disease extent.

Purpose of the Study:

  • To review current surgical techniques and fixation methods for radiocarpal fusions.
  • To discuss advancements in implants and concepts related to wrist fusion surgery.
  • To outline a preferred surgical technique for radioscapholunate fusion with carpal bone excision.

Main Methods:

  • Review of existing literature on radiocarpal fusion techniques and outcomes.
  • Discussion of partial carpal fusion improvements, including distal scaphoid and triquetrum excision.
  • Detailed description of the authors' preferred radioscapholunate fusion technique.

Main Results:

  • Surgical techniques and instrumentation have advanced, leading to improved functional outcomes and reduced complications.
  • Partial carpal fusion techniques, such as distal scaphoid and triquetrum excision, enhance range of motion and fusion rates.
  • The literature supports improved outcomes with modern surgical approaches to wrist fusion.

Conclusions:

  • Radiocarpal fusion remains a vital procedure for managing severe wrist arthritis.
  • Advancements in surgical techniques, including partial carpal fusions with bone excision, offer better functional results.
  • Ongoing innovation in implants and surgical concepts continues to enhance wrist fusion treatment.
