Thomas handle

The Thomas handle (after Hugh Owen Thomas , British orthopedic surgeon, 1834-1891) is an examination method from orthopedics . It is used to detect a flexion contracture in the hip joint .

application

By hyperlordosis (hyperextension with a hollow back) in the lumbar spine, a shortening of the hip flexor muscles can be compensated for, i.e. concealed, in the lying patient. Therefore, with the Thomas handle, one leg is brought into maximum hip flexion (with the knee bent) so that the hollow back is lifted. A hip flexion contracture of the other leg is then evident when the thigh is lifted from the surface, as its shortened thigh muscles ( M. iliopsoas , M. tensor fasciae latae and M. quadriceps femoris ) come under tension from tilting the pelvis. To check that the lumbar lordosis has actually been lifted, the examiner can place a hand between the lumbar spine and the examination table.

This extension deficit (or flexion contracture) can be identified, for example, in the beginning or pronounced osteoarthritis of the hip joint ( coxarthrosis ).
