Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

3.1K
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...

Fractures: Bone Repair

3.2K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.1K
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:

  • Orthopaedic Surgery
  • Trauma Surgery

Background:

  • Proximal humerus fractures are prone to varus collapse and screw cut-out.
  • Arthroplasty is often considered for severe fractures.

Purpose of the Study:

  • To assess fracture union rates using a novel intramedullary plate technique.
  • To evaluate post-operative neck-shaft angles, range of motion, and complication profiles.

Main Methods:

  • Retrospective case series of a novel surgical technique.
  • A 2.0mm mini-fragment plate used as an intramedullary strut for complex proximal humerus fractures.
  • Radiological and clinical assessments of fracture union, neck-shaft angle, range of motion, and complications.

Main Results:

  • All twelve patients achieved bony union with an average follow-up of 10 months.
  • Mean neck-shaft angle was 128°, with functional range of motion achieved.
  • Four patients required revision surgery; no cases of avascular necrosis or infection were reported.

Conclusions:

  • The novel intramedullary plate technique effectively addresses biomechanical challenges in proximal humerus fractures.
  • This technique provides a valuable alternative to arthroplasty for severe fracture patterns.
  • The method is easily implemented using standard orthopaedic instruments.
