We report 74 congenitally dislocated hips treated with premanipulation skin traction, closed reduction under anesthesia, adductor tenotomy and immobilization in the hip… (More)
An optimization procedure is presented for the minimum weight and strain energy optimization for arch structures subjected to constraints on stress, displacement and weight responses. Both thickness and shape variables defining the natural line of the arch are considered. The computer program which is developed in this study can be used to optimize thick,… (More)
Prostaglandin E2-like activity in bone samples from patients with senile osteoporosis was determined and found higher than in samples obtained from normal patients. The results suggest that endogenous prostaglandins may have a role in the pathogenesis of senile osteoporosis.
