Preliminary clinical research on epiphyseal distraction in osteosarcoma in children
BACKGROUND The feasibility of distal femur epiphysis preservation through epiphyseal distraction by external fixator in childhood osteosarcoma was explored. METHODS Between July 2007 and May 2011, 10 children who were suffering from distal femur osteosarcoma received epiphyseal distraction by external fixator, combined with tumor resection and repair with massive allograft bone to preserve th...
متن کاملChondrodiatasis-controlled symmetrical distraction of the epiphyseal plate. Limb lengthening in children.
We describe a technique for slow, progressive, symmetrical distraction of the growth plate using a lightweight dynamic axial fixation system. Results are given for the elongation of 40 bony segments in children with limb-length discrepancies and 60 segments in children with achondroplasia or hypochondroplasia. Increases in limb length of up to 36% were obtained in non-achondroplastic and up to ...
متن کاملLimb lengthening by distraction of the epiphyseal plate. A comparison of two techniques in the rabbit.
We have compared, in rabbits, two techniques of limb lengthening by distraction of the epiphyseal plate using a unilateral external fixation frame. In all cases, 14 mm of symmetrical lengthening without deviation was achieved. With rapid distraction at rates of 1 mm per day (distractional epiphyseolysis) separation of the epiphysis from the metaphysis occurred by day 7, and by day 70 almost com...
متن کاملNonlinearity and Hysteresis of Resonant Strain Gauges
Nonlinearity and hysteresis effects of electrostatically activated, voltage driven resonant microbridges have been studied theoretically and experimentally. It is shown, that, in order to avoid vibration instability and hysteresis to occur, the choices of the ax . and d.c. driving voltages and of the quality factor of a resonator, with a given geometry and choice of materials, are limited by a ...
متن کاملAnalgesic Effect of Distraction during Venipuncture in Children with Thalassemia
Background: Pain is described as the fifth vital sign, and inadequate pain management is linked to numerous immediate and long-term negative outcomes. Venipuncture is one of the most painful medical procedures in children. Distraction is one of the most effective ways to relieve pain. Reducing patients’ pain is important for all nurses for many reasons. Unnecessary pain can damage the nurse-...
