Diagnostic Accuracy of Clinical Tests and Imaging Exams for Femoroacetabular Impingement: An Umbrella Review of Systematic Reviews.

Objective: To synthesize available evidence about diagnostic accuracy of clinical tests and imaging examinations for femoroacetabular impingement (FAI) syndrome.

Design: Umbrella review.

Setting: N/A.

Evaluation of the thickness of the proximal femoral canal in patients living at altitude.

Objective: Our goal is to confirm the hypothesis that people who were born and raised on cities at altitude have a smaller proximal femoral canal.

Methods: Prospective study with 169 participants, divided into two groups. Group A: 99 patients who were born and raised at altitude and group B: 70 patients who were born and raised at low altitude.

COMPLICATIONS IN HIP ARTHROSCOPY.

Objectives: To determine the prevalence of complications in a series of consecutive cases of hip arthroscopy; to assess the progression of the sample through a learning curve; and to recognize the causes of complications in arthroscopic hip operations.

Method: 150 consecutive cases that underwent hip arthroscopy between May 2004 and December 2008 were evaluated. The complications encountered were classified in three ways: organic system affected, severity and groups of 50 consecutive cases.
