Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.6K
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: Humerus01:19

Bones of the Upper Limb: Humerus

13.5K
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...

Muscles that Move the Arm01:31

Muscles that Move the Arm

5.4K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Muscles that Move the Forearm01:16

Muscles that Move the Forearm

4.5K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.9K
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...

Muscles of the Shoulder01:23

Muscles of the Shoulder

9.8K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Area of Science:

  • Orthopedics
  • Infectious Diseases
  • Dermatology

Background:

  • Olecranon bursitis is a frequent musculoskeletal condition.
  • It can present as acute or chronic, and septic or aseptic.
  • Distinguishing between septic and aseptic forms is clinically challenging.

Purpose of the Study:

  • To review current literature on olecranon bursitis.
  • To clarify optimal antibiotic treatment for septic olecranon bursitis.
  • To provide a guide for clinical treatment decisions.

Main Methods:

  • Systematic literature review of reported olecranon bursitis cases.
  • Compilation of physical examination findings and laboratory data.
  • Summary of current treatment practices.

Main Results:

  • Key physical findings differ between septic and aseptic olecranon bursitis: tenderness (88% vs 36%), erythema/cellulitis (83% vs 27%), warmth (84% vs 56%), trauma/lesion (50% vs 25%), and fever (38% vs 0%).
  • Significant overlap exists in physical and laboratory data.
  • Antibiotic treatment evidence varies.

Conclusions:

  • Clinical differentiation between septic and aseptic olecranon bursitis is difficult due to overlapping signs and symptoms.
  • Current evidence on optimal antibiotic therapy duration and route for septic olecranon bursitis is inconsistent.
  • This review synthesizes data on causative bacteria, physical findings, laboratory results, and treatments to assist clinicians.
