Anatomical And Functional Study Of The Medial Collateral Ligament Complex Of The Elbow

Objective: To carry out an anatomical study of the medial collateral ligament, an important elbow stabilizer in different degrees of elbow flexion-extension. Methods: Forty elbows were dissected in order to analyze the functional behavior of the anterior, posterior and transverse ligament bands during valgus stress maneuvers of the elbow in different degrees of flexion and extension. Two groups were determined; in the group GPA the posterior band of the ligament was sectioned initially, then the articular capsule and finally the anterior band; in group GAP this order was reversed. Results: Instability was observed in GPA only in the third stage, when there was a greater mean elbow's opening during the flexion (between 50° and 70°); in GAP, the instability was present since the first stage; the degrees of flexion with greater instability were the same as in group GPA. Conclusion: The anterior band of the medial collateral ligament of the elbow is the most important stabilizer of the elbow valgus instability, and its principal action occurs between 50° and 70° of elbow flexion.

Translation And Cross-cultural Adaptation Of The Rowe Score For Portuguese

Objective: To translate and culturally adapt the Rowe score for use in Brazil. Methods: The translation and cross-cultural adaptation process initially involved the steps of translation, synthesis, back- -translation and revision by the Translation Group. The pre-final version of the questionnaire was then created. The Stability and Function fields were applied to 20 patients with anterior shoulder luxation, and the Mobility field was applied to 20 health professionals. Results: It was found that some of the patients had difficulty understanding some of the expressions of the questionnaire, so these were replaced with terms that were easier to understand. All health professionals understood the translation of the Mobility field. The altered questionnaire was then reapplied to another 20 patients, and this time it was understood by all the assessed subjects. Conclusion: After a careful process of translation and cultural adaptation, a definitive version of the Rowe questionnaire was obtained in Brazilian Portuguese.
