Abstract:
Osteochondral flap fracture in a child is rare. A 7 year-old boy with an osteochondral flap fracture is reported. Intraoperatively, the osteochondral fragment in the olecranon fossa was connected to a part of the medial collateral ligament. The authors suppose that this type of fracture occur not only as a result of a shearing force of the trochlea but also by a traction force through the medial collateral ligament when a complete tear of the medial collateral ligament was avoided for any reason. Furthermore, the immaturity of bone of the child may result in avulsion fracture, not in injury of the distal part of the ligament. Osteosynthesis with poly-L-lactic acid pins was useful to reacquire good elbow function.

Fractures: Bone Repair
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...
Flail Chest-I
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 Age
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...
