ABSTRACT
Immobilization osteoporosis (IOP)is a common complication in clinic and cosmonauts. It severely impaired the patients ant the cosmonauts. The causes of IOP are weightless,immoblization and bed rest.Excercise therapy is very important for IOP. The etiology andpathogenesis of IOP are introduced in this article. the effects, mechanism and methods of the exercise therapy for preventing and treating IOP arealso discussed.
ABSTRACT
Objective To evaluate the results of the treatment and prevention measures for pathological dislocation of the hip following septic arthritis in the newborns. Methods Twenty cases undergone open reduction were studied restropectively. In addition, greater trochanterplasty was penformed in 15 cases, acetabularplasty in 14 cases, greater and lesser trochanterplasty in 2 cases. Rusults A successful rate of reduction achieved in 90％ of the patients; however, central reduction was achieved in only 38.8％ . 20 patients were followed-up for 6 months to 12 years. The stability and motility of the hip gradually improved in majority of the patients. The cases with severe destruction followed by absence of femoral head and neck had unsatisfactory results. Shortening deformity were found in six cases, and subluxation, dislocation, rigidity of the hip in one case each. Conclusion The greater trochanterplasty had a good result for reduction and maintaining the position. Early diagnosis and early open drainage were key measures for prevention of pathological dislocation of the hip resulting from the acute septic arthritis in the newborn.
