Study Design: Ex vivo study of the mechanical performance of cylindrical and dual-core pedicle screws after insertion, removal, and reinsertion in the same hole. Objective: To evaluate the effect of repeated use of same screw hole on the insertion torque and the retentive strength of the cylindrical and dual-core screws. Summary of Background Data: Insertion and removal of pedicle screws is sometimes necessary during surgical procedure to assess the integrity of the pilot-hole wall. However, this maneuver may compromise the implant-holding capacity. Methods: Sixty thoracolombar vertebrae (T13–L5), harvested from 10 healthy calves, were used to insert 2 different designs of pedicle screws: cylindrical (5.0-mm outer diameter) and dual-core screws (5.2-mm outer diameter). Three experimental groups were created on the basis of the number of insertions of the screws and 2 subgroups were established according to the core pedicle screw design (dual-core and cylindrical). The insertion torque was measured during initial insertion, second insertion, and third insertion. Pullout screw tests were performed using a universal testing machine to evaluate the pullout strength after initial insertion, second insertion, and third insertion. Results: Significant reductions of 38% in mean insertion torque and 30% in mean pullout strength of dual-core screw were observed between the initial insertion and the third insertion. The cylindrical screw observed significant reductions of 52.5% in mean insertion torque and 42.3% in mean pullout strength between the initial insertion and the third insertion. A reduction of mean insertion torque and pullout strength between the first insertion and the second insertion but without significance was also observed for both types of screws. Conclusion: Insertions and reinsertion of either cylindrical or dual-core pedicle screws have compromised insertion torque and pullout strength of the implants as measured by mechanical tests.

The role of an occupational therapist in the Mental Health team, particularly in the Rehabilitation and Assisted Discharge Program (PREA), is to provide a focus on the person and on a meaningful occupation for him. The interdisciplinary team of each device, involving an occupational therapist, performs planning goals and implementing the means to achieve through strategies of psychosocial rehabilitation. Meanwhile, intervention strategies are developed and individual support for each person is given to carry out a project of life in the community, building a social, occupational and significant work in order to enhance users’ recovery.

Background: This study was designed to identify factors associated with return to work and quality of life in patients undergoing primary coronary artery bypass at age <50 years. Methods: 172 patients %%T::49%%As part of a larger randomized controlled trial, 74 participants were randomized on day five following admission to intensive care (ICU) to a protocolized rehabilitation program that commenced in ICU, continued on the acute care ward and for a further eight weeks following hospital discharge as an outpatient program. Exercise training was prescribed based on objective outcome measures to achieve a physiological training response. RESULTS: /b>During acute hospitalization 60% of exercise sessions were able to be delivered. The most frequent barrier to exercise was patient safety and patient refusal due to fatigue. Point prevalence data showed patients were mobilized more often and for longer periods compared to standard care. Outpatient classes were poorly attended with only 41% of patients completing more than 70% of outpatient classes. No adverse events occurred.LimitationsLimitations include patient heterogeneity and delay to commencement in exercise in ICU due to issues of consent and recruitment. CONCLUSIONS:/b>Exercise training that commences in the ICU and continues through to an outpatient program is safe and feasible for survivors of critical illness. Models of care that maximize patient participation across the continuum of care require further investigation.
