Muscles of the Shoulder01:23

Muscles of the Shoulder

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.

Flail Chest-I01:24

Flail Chest-I

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

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...
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...
Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
Muscles that Move the Arm01:31

Muscles that Move the Arm

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...

Summary

Bipolar clavicle dislocation, a rare shoulder injury, often fails with conservative treatment. Surgical repair using an oblique T-plate and Kirschner wire offers satisfactory recovery and full shoulder function.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Shoulder Joint Injuries

Background:

  • Bipolar dislocation of the clavicle involves both the acromioclavicular and sternoclavicular joints, representing an uncommon yet significant traumatic injury.
  • Previous conservative treatment approaches for this condition have been linked to issues such as redislocation, functional impairment, and cosmetic deformity.

Purpose of the Study:

  • To present a case report on the surgical management of bipolar clavicle dislocation.
  • To highlight the effectiveness of a specific surgical technique in achieving satisfactory patient outcomes.

Main Methods:

  • A 41-year-old female patient with bipolar dislocation of the right clavicle underwent surgical intervention.
  • The surgical procedure involved open reduction and internal fixation, utilizing an oblique T-plate for the sternoclavicular joint and Kirschner wire stabilization for the acromioclavicular joint.

Main Results:

  • The patient experienced a satisfactory recovery following the surgical treatment.
  • Full range of motion and normal muscular strength were restored in the affected right shoulder.
  • The reported outcomes were sustained at a 2-year follow-up.

Conclusions:

  • Surgical management, specifically open reduction and internal fixation with an oblique T-plate and Kirschner wires, is an effective treatment for bipolar clavicle dislocation.
  • This approach can lead to excellent functional recovery and stability, addressing the limitations of conservative methods.
  • The rarity of the condition and the successful long-term outcome warrant reporting this case.
