Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

11.3K
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

5.9K
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

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...

Functional Classification of Joints01:09

Functional Classification of Joints

8.2K
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 Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

8.3K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Area of Science:

  • Orthopedic surgery
  • Traumatology
  • Skeletal biomechanics

Background:

  • Multifocal humeral fractures, involving multiple sites like the neck, shaft, or distal humerus, are exceptionally rare.
  • Existing literature lacks a standardized classification system for these complex fractures.
  • Current AO classification addresses bifocal diaphyseal fractures but not proximal-metaphyseal-diaphyseal patterns.

Purpose of the Study:

  • To introduce a novel classification system for multifocal humeral fractures.
  • To provide a framework for surgical decision-making in treating these rare injuries.
  • To improve the understanding and management of complex humeral fractures.

Main Methods:

  • A retrospective review of 717 surgically treated humeral fractures from 2004 to 2010.
  • Identification of 35 patients with associated proximal and diaphyseal humerus fractures.
  • Surgical treatment involved plate and screw fixation in 34 patients and external fixation in one.

Main Results:

  • A proposed classification system categorizes fractures into Type A (proximal and shaft), Type B (diaphysis only), and Type C (diaphysis and distal humerus).
  • Type A fractures are further subclassified (A-I, A-II, A-III) based on displacement and comminution.
  • Mean follow-up was 3 years and 3 months, with surgical synthesis as the primary treatment modality.

Conclusions:

  • Multifocal humeral fractures are under-described, necessitating a clear classification for effective treatment.
  • The proposed classification primarily addresses fractures involving the proximal humerus and shaft.
  • This system aims to guide surgeons in choosing the optimal surgical synthesis for multifocal humeral fractures.
