Investigation of the bone mineral density of the hip on the lightly hemipiegia patients

Objective Many hemiplegia patients suffer from the hip fracture, and most of them happened on the paralysis side, In order to understand the causes of the higher incidence of the hip fracture on the paralysis side, we measure the bone mineral density of the hip, and trying to find out the correlation between the fracture and the bone content of the hip. Methods 60 cases of the stroke patients were selected, 35 are male, from 48-78 years old, with an average of 67 years old, 25 cases are female , from 48-70 years old, with an average of 61 years old, with medical history from half a year to 17 years, with an average of 6 years. Mobility function is graded according to their walking ability. 60 people with the comparable age were selected as the control. Bone mineral density was measured on both side of the hip individually with DEXA. Results For the lightly hemiplegia patients , no matter whether they have claudication , there is no significant difference of the bone mineral density on the hip between the paralysis side and the normal one( P 0.05), and there is also no significant difference compare with the normal control ( P 0.05 ) . Conclusion The higher incidence of the hip fracture on the paralysis side in the hemiplegia patient is not related with the bone content of the hip. Probably it is related with mobility dysfunction on the paralysis side, and the weight tilt on that side, and falling easily comes on the side too.
