Muscles of the Shoulder01:23

Muscles of the Shoulder

9.7K
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...

Flail Chest-II

848
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

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...

Muscles that Move the Arm01:31

Muscles that Move the Arm

5.3K
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...

Rheumatic Heart Disease I: Introduction

785
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Fractures: Bone Repair01:27

Fractures: Bone Repair

6.4K
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...

Area of Science:

  • Sports Medicine
  • Epidemiology
  • Orthopedics

Background:

  • Shoulder injuries are common in contact sports like rugby union.
  • Understanding injury incidence and severity is crucial for player safety and program development.

Purpose of the Study:

  • To determine the incidence, severity, and types of shoulder injuries in adult community rugby union.
  • To compare injury rates between semi-professional and recreational players.
  • To identify player positions and game events most associated with shoulder injuries.

Main Methods:

  • Prospective study analyzing shoulder injuries over a four-year period (2009-2013).
  • Data collected on injury incidence (per 1000 hours), severity (weeks missed), injury type, player position, and causative event.
  • Statistical analysis to compare injury rates between different player levels and positions.

Main Results:

  • A total of 254 time-loss shoulder injuries were reported, with an overall incidence of 2.2 per 1000 hours.
  • Semi-professional players had a higher incidence (2.8/1000h) than recreational players (1.8/1000h).
  • Acromioclavicular joint injuries were more frequent in semi-professional players. Back row players had the highest incidence of shoulder injuries (2.9/1000h). The tackle was the most common injury-associated event.

Conclusions:

  • Rugby union match play presents a considerable risk of shoulder injuries.
  • Targeted injury prevention strategies focusing on tackle technique and shoulder conditioning are essential, particularly for semi-professional players and those in back row positions.
