Hip Clinical Assessment

Question 1

What was the sensitivity and specificity of the AB-HEER test for hip micro-instability?

Answer 1

Sensitivity 80%, Specificity 90%

The AB-HEER test is noted for being the most accurate among the tests assessed.

Question 2

What is the negative likelihood ratio of the AB-HEER test?

Answer 2

0.22

This indicates it is the best performer among the tests for hip micro-instability.

Question 3

What are the limitations of the study on hip micro-instability tests?

Answer 3

Selection bias and increased prevalence of instability

Patients were already assessed for arthroscopy, which may skew results.

Question 4

What is the sensitivity and specificity of the Prone instability test?

Answer 4

Sensitivity 34%, Specificity 98%

This test demonstrates high specificity but low sensitivity.

Question 5

What does the FADDIR test indicate regarding sensitivity and specificity for femoroacetabular impingement syndrome?

Answer 5

Sensitivity 94-99%, Specificity 5-9%

The FADDIR test is more useful as a screening test rather than a definitive diagnostic tool.

Question 6

What is the positive likelihood ratio of the Flex/IR test?

Answer 6

1.28

This indicates that a positive finding does not offer a meaningful increase in post-test probability.

Question 7

What were the sensitivity and specificity of the Prone internal rotation test?

Answer 7

Sensitivity 29%, Specificity 94%

This test shows high specificity but low sensitivity, similar to the Prone instability test.

Question 8

Which test for hip micro-instability had the highest specificity?

Answer 8

Prone instability test

While it has high specificity, its sensitivity is relatively low.

Question 9

Fill in the blank: The AB-HEER test is noted for its high __________ and specificity.

Answer 9

sensitivity

This high sensitivity makes it a reliable test for assessing hip micro-instability.

Question 10

True or False: The Flex/IR test has a higher specificity than the FADDIR test.

Answer 10

True

The Flex/IR test has a specificity of 25%, while the FADDIR test has a specificity of 5-9%.

Question 11

A patient presents with a suspected distal syndesmosis injury. What test could you use to rule in or out

Answer 11

Standing on single foot test - binded (SOSF-B)

sensitivity 84%, Specificity 87%
