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...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

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 short...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Summary

This case report details a rare bilateral capitellum humerus fracture. Early mobilization and fixation with a mini-screw led to optimal outcomes, despite later degenerative changes in one elbow.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Bilateral capitellum humerus fractures are exceedingly rare injuries.
  • This report presents a unique case of a 33-year-old female sustaining this injury after a fall.

Observation:

  • The patient underwent emergency surgical treatment: open reduction and internal fixation with Kirschner wires and a mini-fragment screw.
  • Early physical rehabilitation commenced within the first week post-surgery.

Findings:

  • Radiographs at 9 weeks demonstrated acceptable bone union in both elbows.
  • Despite successful initial union, the patient developed persistent pain and a 35-degree flexion deficit in the right elbow by the 2-year follow-up, attributed to degenerative changes.

Implications:

  • This case highlights the rarity of bilateral capitellum humerus fractures.
  • Optimal outcomes may be achieved with early mobilization and anatomical reduction, stabilized by fixation methods like mini-screws, though long-term degenerative changes remain a consideration.
