Summary
Motocross riders often sustain wrist injuries, particularly scaphoid fractures, due to extreme wrist hyperextension during jumps. Early surgical intervention and rehabilitation allow a return to sport within ten weeks.
Area of Science:
- Orthopedics
- Sports Medicine
- Traumatology
Background:
- Motocross racing imposes significant physiological and psychological demands, leading to frequent upper extremity injuries.
- While upper extremity strength differences exist in motocross riders, wrist injuries, specifically scaphoid fractures, lack detailed injury mechanism analysis.
Observation:
- Three motocross riders presented with scaphoid fractures resulting from extreme wrist hyperextension during landing after jumps.
- Two Herbert type C fractures were treated late (3 months post-trauma), while one Herbert type B2 fracture received prompt surgical intervention (within a week).
Findings:
- Scaphoid fractures in motocross are predominantly caused by hyperextension, contrasting with flexion-related wrist injuries.
- Herbert type B2 fractures were treated with open reduction and Herbert-screw fixation.
- Herbert type C fractures required Herbert-screw fixation combined with a cortico-cancellous bone graft.
Implications:
- Prompt surgical treatment for scaphoid fractures in motocross athletes facilitates a return to sport within approximately ten weeks.
- Preventive measures should focus on eccentric training for muscular wrist stabilization and external support via rigid gloves to limit hyperextension.

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.

01:27Fractures: Bone Repair
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 procedure...

01:26Flail Chest-II
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.

01:31Muscles 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...

01:09Bones of the Upper Limb: Radius
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 short...

01:19Bones 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...
