This classification helps compare the accuracy of screw insertion in range of conditions by considering the complexity of screw insertion. Considering the clinical scenario of complex pedicle anatomy in spinal deformity AIRO navigation showed an excellent accuracy rate of 96.2%.
The study showed no greater advantage of higher energy, and DA VMAT plan with 6 MV photon energy was a good choice of treatment for carcinoma cervix as it delivered a highly homogeneous and conformal plan with superior target coverage and better OAR sparing.
There were significant differences in Sc values measured for 6MV-FB and unflattened 7MV-UFB photon beams over the range of field sizes from 10 cm × 10 cm to 40 cm × 04 cm. Different results were obtained for measurements performed with low-Z and high-Z mini phantoms.
Study design: Prospective study. Objectives: In a prospective study, 45 consecutive cases of cervical spinal cord injury without radiographic evidence of trauma (SCIWORET) who were treated non-operatively were analyzed to correlate the magnetic resonance image findings with the initial neurological deficit and the extent of neurological recovery at 2 years. Setting: University tertiary-care teaching hospital in South India. Methods: The neurological status of patients who did not have any radiographic or computerized tomographic abnormality at the time of admission was assessed by ASIA Impairment Scale (AIS) modification of Frankel's grading. The spinal cord abnormality seen in the magnetic resonance imaging was noted. The neurological status at the end of 2 years was recorded. Results: Twenty-seven of the 45 patients (60%) had cord oedema, 8 (17.77%) had cord contusion, 8 (17.77%) patients had a normal cord and 2 (4.44%) patients had cord swelling on the magnetic resonance image. Out of 27 patients who presented with cord oedema, 14 (31.11%) patients recovered from AIS D to AIS E and 6 (13.33%) patients did not recover and remained at AIS D. Seven (15.55%) patients who had a normal cord recovered completely to AIS E. Five (11.11%) patients who had contusion of the cord recovered up to AIS D. Conclusion: The initial neurological status correlates with magnetic resonance imaging findings. Subsequent neurological recovery is dependent on the type of cord damage and initial neurological status. The rate of recovery and the final motor outcome are inversely related to the length of cord involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
