    1 year

  • Canal fill ratio

    Immediately after surgery

Other Outcomes (3)

    Immediately after surgery

Study Arms (2)

Anterolateral approach

ACTIVE COMPARATOR

Standard x-ray on all operated patients was taken pre- and postoperative and at 3 and 12 moths. Including an AP pelvis and lateral view of the hip.

Procedure: Hemiarthroplasty

Lateral approach

ACTIVE COMPARATOR

Standard x-ray on all operated patients was taken pre- and postoperative and at 3 and 12 moths. Including an AP pelvis and lateral view of the hip.

Procedure: Hemiarthroplasty

Interventions

Radiological features comparing the femoral stem position is measured on the postoperative x-ray. Presence of heterotopic ossification is assessed on the 12 months follow up.
