Muscles of the Shoulder01:23

Muscles of the Shoulder

8.5K
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...

Muscles that Move the Arm01:31

Muscles that Move the Arm

4.4K
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...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

6.6K
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...

Flail Chest-I01:24

Flail Chest-I

496
Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

3.3K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Functional Classification of Joints01:09

Functional Classification of Joints

6.3K
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.
Synarthrosis

Summary

Clavicle fractures, the most common bone breaks, often affect the midshaft and are typically treated non-surgically with immobilization. Other clavicle conditions like distal clavicle osteolysis and acromioclavicular joint injuries have varied management based on severity.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Radiology

Background:

  • The clavicle (collarbone) is the most frequently fractured bone, with the midshaft being the most common site.
  • Clavicle injuries encompass fractures, distal clavicle osteolysis, and acromioclavicular (AC) joint injuries, each with distinct etiologies and presentations.

Purpose of the Study:

  • To provide an overview of common clavicle injuries, including fractures, distal clavicle osteolysis, and AC joint injuries.
  • To outline the diagnostic modalities and management strategies for these conditions.

Main Methods:

  • Review of common clavicle pathologies including midshaft clavicle fractures, distal clavicle osteolysis, and acute AC joint injuries.
  • Discussion of diagnostic imaging, primarily X-ray for clavicle fractures.
  • Outline of conservative and surgical treatment options based on injury classification and severity.

Main Results:

  • Midshaft clavicle fractures are typically managed conservatively with 4 weeks of immobilization followed by rehabilitation.
  • Distal clavicle osteolysis and AC joint osteoarthritis often present with similar symptoms and are managed with conservative measures, with surgery as an option.
  • Acute AC joint injuries are classified using the Rockwood system, with low-grade injuries treated non-surgically and high-grade injuries requiring surgical intervention.

Conclusions:

  • Conservative management is the mainstay for uncomplicated clavicle fractures and low-grade AC joint injuries.
  • Treatment for distal clavicle osteolysis, AC joint osteoarthritis, and high-grade AC joint injuries is tailored to the specific condition and severity, often involving a combination of conservative and surgical approaches.
