Growth is commonly defined as an increase in size, but more specificity is needed. An increase in size of the whole body or of an organ such as a bone may be caused by one or a combination of three processes: (1) Hyperplasia, or an increase in cell numbe
Bone lengthUlnaHumerusMechanical stimulation plays a critical role in bone development and growth. In view of recently recognized anabolic responses promoted by a joint-loading modality, we examined the effects of elbow loading on longitudinal growth of the ulna and the humerus. Using a custom-made...
One National Collegiate Athletic Association (NCAA) center for a Final Four basketball team sustained a nondisplaced navicular fracture. The athlete used both a high-intensity ultrasound machine and a bone stimulator for a month before gradually resuming play with an arch support. Two months after t...
Evidence suggests that bone cells produce substantial quantities of growth factors for extracellular storage in bone matrix. Apart from being produced for extracellular storage, it is possible that growth factors secreted by bone cells have acute effects on their neighboring osteoblastic cells, i.e., ...
Long bone diameters on the other hand, are among the last areas of the skeleton to reach maturity and this is in part due to the delayed spurt in muscle growth especially in the adolescent male. Fusion in most postcranial bones takes place at a growth plate between a primary centre and ...

Bone growth stimulators are worn to help people with fractures or surgery heal bone. Two types of stimulators are used and have shown some promise. Learn more.

Prior analysis of bone age is essential, using the Greulich–Pyle atlas for the wrist, and the Sauvegrain–Nahum method for the elbow. There are, however, many other possibilities and, as Bronfen recommends[2], it is wise and useful to use two in a given patient, to minimize risk of ...
