Correct Answer � A Explanation |

Ans: A) Thomas test.
Thomas Test:
- The aim of the test is to remove the compensatory lumbar lordosis so that the flexion deformity becomes obvious and can be measured.
- The patient is asked to lie supine on a hard surface, with legs straight.
- He may be able to do so despite the flexion deformity by producing excessive lumbar lordosis.
- The same can be appreciated by the examiner passing his hand behind the patient’s lumbar spine.
- Now, the sound hip of the patient is flexed gradually. After the hip flexion is complete, the pelvis begins to tilt.
- This obliterates the lumbar lordosis, as can be felt by the hand under the lumbar spine. As this happens, the affected hip will automatically come to be in the deformed position (flexion position).
- The angle between the affected thigh and the bed is the degree of flexion deformity.
