Summary
Elite cricketers
Area of Science:
- Sports Medicine
- Orthopedics
- Biomechanics
Background:
- Cricketers' shoulders exhibit unique musculoskeletal adaptations, differing from baseball "thrower's shoulder."
- Understanding these adaptations is crucial for injury prevention in elite cricketers.
Purpose of the Study:
- To characterize the specific musculoskeletal profile of cricketers' shoulders.
- To identify predictors of dominant shoulder injury in elite South African cricketers.
Main Methods:
- A prospective longitudinal cohort study involving 105 elite cricketers.
- Pre-season screening included questionnaires, ultrasound, and 14 musculoskeletal tests.
- Shoulder injuries were tracked throughout the 2016/2017 cricket season.
Main Results:
- 17% of cricketers sustained a shoulder injury during the season.
- A thickened dominant supraspinatus tendon (≥5.85 mm) predicted injury (Sensitivity: 72%, Specificity: 63%).
- A shortened non-dominant pectoralis minor muscle (≤12.85 cm) also predicted injury (Sensitivity: 83%, Specificity: 55%).
Conclusions:
- Cricketers' shoulder adaptations differ significantly from baseball players.
- Thickened dominant supraspinatus tendon and shortened non-dominant pectoralis minor are risk factors for shoulder injury.
- Preventative strategies and workload management are needed for cricketers prone to shoulder injury.

01:23Muscles of the Shoulder
9.0K
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.

01:31Muscles that Move the Arm
4.7K
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...

01:19Bones of the Upper Limb: Humerus
7.0K
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...

01:09Bones of the Upper Limb: Radius
4.5K
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...

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.

01:15Bones of the Upper Limb: Ulna
4.2K
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...
