OBJECTIVE The aim of our study was to investigate the effects of haemostatic agents used at the autograft donor sites in spinal fusion. METHODS The study included 66 patients (26 men, 40 women; mean age: 42.9 years) who underwent spinal fusion surgery between March 1999 and October 2002. Patients were randomly assigned to 4 different groups according to(More)
Sliding lengthening and Z-lengthening techniques are widely used in heel cord lengthening. Even though most surgeons performing these procedures apply a short leg cast after surgery, their postoperative immobilization intervals vary from 3 to 7 weeks. Nather et al. showed that there was no need for immobilization after the musculotendinous lengthening of(More)
In this paper, we introduce an inertially actuated robot that moves in the horizontal plane. The robot is actuated by using two spinning masses. The mathematical model of the system is developed and the equations of motion are derived. The role of surface friction in the robot's motion is also investigated. We presented a theorem that proves the(More)
