Brief Summary

Gluteus maximus transfer following THA does not improve abductor strength - a case-control gait analysis study of 15 patients with gluteus medius disruption The investigators have compared 15 gluteus maximus transferred patients with the use of a gait analysis system based on reflective markers and force plates to objectively evaluate the gait performance pre- and postoperatively.

Conditions

Hip Arthropathy

Outcome Measures

Primary Outcomes (2)

• Abductor strength measurement with use of an optical tracking system after Gluteus maximus transfer - a case-control gait analysis study of 15 patients pre- and postoperative with gluteus medius disruption

  Gait analysis examination/measure will be performed preoperative with an optical tracking system in a gait laboratory using reflective markers and integrated force plates in order to record kinetics (Nm/kg) of abductor muscles moment in the frontal plane.

  Preop

• Abductor strength measurement with use of an optical tracking system after Gluteus maximus transfer- a case-control gait analysis study of 15 patients pre- and postoperative with gluteus medius disruption

  Gait analysis examination/measure will be performed 2 year postoperative with an optical tracking system in a gait laboratory using reflective markers and integrated force plates in order to record kinetics (Nm/kg) of abductor muscles moment in the frontal plane.

  Postop 2 year
