Acetabular index evolution on 4 months to 10 years age children
Universidad Privada Antenor Orrego
Orthopaedics and Rehabilitation
Orthopedic and Traumatology unit. Surgical Specialty Center. Surgery department. Hospital Regional Docente de Trujillo.
Dr. Augusto Salazar
Dr. Félix Eduardo Díaz Vera
Type of Research Project
- Basic science
What is the background of the project?
The value of the acetabular index varies by sex, age and affected side, also by geographic area. The objective of this study is collect all data in our environment to be compare in others, this also work as base to discard hip displays diagnosis. Teach about the basic knowledge about hip dysplasia and the different methods to evaluate it, so we can then proceed to evaluate the normal grown and development of the acetabulum in children by acetabular angle measurement by the correct review of the x-ray films taken during the patient’s follow-up in children from 4 moths to 10 years old. Then classified them by age, sex, social condition, race and side. So we can order and classify the data taken.
What is the aim of the project?
Evaluate the normal grown and development of the acetabulum in this group of children with the objective of have the normal acetabular index values, to be used in the radiological evaluation of the children’s hips, and discard hip dysplasia.
What techniques and methods are used?
They will study and measure the acetabular angles by using anteroposterior simple pelvic radiographies in this group of children by using a conventional goniometer. It will be 7 groups by ages, from 4 moths to 8 moths; from 8 months to 1 year; from 1 to 2 years; 2 to 4 years; from 4 to 6 years; from 6 to 8 years; and from 8 to 10 years. All data will be put in a data sheet specially design for this study, later will be analyzed in SPAD y SSPS, with a high significance level of P<0,01 and P>0,05 as no significant; T student will be also applied.
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- The tasks of the student will be performed on his/her own
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
Review of patients clinical stories, select the patients for the studies and classified them by age, sex and side, help with the measurement of the acetabular angle in the patients, help with their respective follow-up, help with the radiological procedures and review of X-ray films taken during the evaluation of the children’s hips. Also helping with the diagnosis, discard hip dysplasia.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Read about Hips Dysplasia and Acetabular angle measurement.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Bibliographic search, knowledge about radiographies lecture.
Are there any legal limitations in the student’s involvement
