Annotated Bibliography
Complete two annotated bibliographies for each week’s assignment.AB’s should be ½ to ¾ pages long.
It should be double-spaced, and you are to use Times new Roman 12 font. For your AB, you must have:
• Your name, date, course, and AB number at the top (see example)
• APA Reference before the information (see example) Annotated bibliographies must be written in manner, in which, they are understandable. You must describe all-important data such as:
• The participants • The reason the study was conducted
• What research design was used (surveys, interviews, case study, etc.)
• Which research analysis was used (MANOVA, ANOVA, Kruskal Wallace, etc.)
• The results of the study along with any conclusions of the author(s) Your study must include all of these (if applicable). Your AB MAY NOT be copied and pasted directly from the source. There MUST NOT be any form of plagiarism in your annotated bibliography (or any other assignment). You are required to write this assignment in your own words. You should pick the topic for your AB from the objectives listed at the beginning of each week’s module or from the syllabus.
1)Development of a Patient-specific Guide for High Cervical Spine Fixation
description:
Abstract Objective High cervical spine fixation represents a challenge for spine surgeons due to the complex anatomy and the risks of vascular and medullar injury. The recent advances in 3-D printing have unfolded a whole new range of options for these surgeons. Methods In the present study, a guide for the placement of the lateral mass screw in the C1 vertebra was developed using 3-D printing. Eight real-size models of the high cervical spine and their respective screw guides were built using computed tomography (CT) scan images. The guidewires were inserted with the help of the printed guides and then the models were analyzed with the help of CT scan images. Results All of the guidewires in the present study obtained a safe placement in the models, avoiding the superior and inferior articular surfaces, the vertebral foramen, and the vertebral artery. Conclusion The present study demonstrated the efficiency of the guide, a reliable tool for aiding the insertion of guidewires for screws in lateral masses of the C1.

2)Comparative Study of Function and Quality of Life in Patients with Fracture of the Tibial Plateau Operated with Locked or Conventional Plates
Description:
Abstract Objective To compare clinical, functional, and quality of life outcomes between patients with tibial plateau fractures operated with locked or conventional plates, and to compare the costs of these implants. Methods This was a comparative cross-sectional study of a consecutive series of patients with tibial plateau fractures treated surgically from August 2015 to June 2016. Patients < 18 years old, those unable to answer the questionnaires or to attend the outpatient reassessment, polytrauma patients, those with associated injuries on the ipsilateral limb, and patients who had not undergone treatment with bone plates were excluded. The present study compared the costs of the implants for the hospital, quality of life (with the 12-Item Short Form Health Survey [SF-12]), Lysholm score, pain scale, and clinical and radiological parameters. Results A total of 45 patients with tibial plateau fractures were admitted, and 11 cases were excluded. Two cases were lost to follow-up; therefore, 32 remained for the analysis (94%). The mean follow-up time was of 15.1 months (standard deviation [SD] = 4.8 months). In group A (locked plates), there were 22 patients (69%), at an average hospital cost of BRL 4,125.39/patient (SD = 1,634.79/patient) for the implants. In group B (conventional plates) there were 10 patients (31%), at an average cost of BRL 438.53 (SD = 161.8/patient) (p < 0.00001). For the other parameters, no differences were observed, except for a greater articular depression in group A (2.7 mm ± 3.3 mm versus 0.5 mm ± 1.6 mm; p = 0.02; TE = 0.90). Conclusion The costs of locked implants for the treatment of tibial plateau fractures are significantly higher than those of conventional implants, without any clinical, quality of life, radiological, or functional advantages of the locked implants demonstrated in the present series.
