| It has been given preference to external fixation as means of fracture immobilization, and transcortical pins and fiberglass cast have been used. |
| Prolonged immobilization, such as may occur with hospitalization, trauma, or general debility, is one risk factor. |
| Nondisplaced fractures of the base of the metacarpals are treated with immobilization in a short arm cast. |
| Cultivation generally increases net nitrification through liming, aeration, enhanced ammonium levels, and lower immobilization. |
| Postoperatively, the arm should be maintained in relative immobilization for at least 3 weeks. |
| However, if the discomfort localizes over the navicular bone, further immobilization or surgical intervention may be indicated. |
