Muscles of the Forearm that Move the Hand and Fingers01:17

Muscles of the Forearm that Move the Hand and Fingers

1.1K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

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: Radius

2.3K
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...

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Musculoskeletal Research

Background:

  • Scapholunate instability is a common cause of wrist pain and dysfunction.
  • Ligamentous reconstruction techniques aim to restore carpal stability.
  • Bone tunnels are frequently created for graft fixation in these reconstructions.

Purpose of the Study:

  • To document carpal bone tunnel collapse as a complication.
  • To highlight bone necrosis following bone tunneling for ligamentous reconstruction.

Main Methods:

  • Retrospective case series of six patients.
  • Analysis of complications after bone tunneling for scapholunate reconstruction.
  • Involved both scaphoid and lunate bones.

Main Results:

  • Six cases of carpal collapse or bone necrosis were identified.
  • All cases occurred after ligament reconstruction for chronic scapholunate dissociations.
  • No preoperative deformities of the scaphoid or lunate were present.

Conclusions:

  • Carpal bone tunnel collapse is a potential complication of scapholunate reconstruction.
  • The incidence is unknown, but consequences can be significant.
  • Informed consent should include this risk for patients undergoing surgery for chronic scapholunate instability.
