Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate, whether the iliopsoas plane block affects the muscle strength of the quadriceps femoris muscle.;Secondary Objective: To estimate: - the effect of the iliopsoas plane block on the strength of the adductor muscles of the thigh. - the effect of the iliopsoas plane block on sensitivity in the dermatome of the lateral cutaneous femoral nerve. - the effect of the iliopsoas plane block on sensitivity in the dermatome of the femoral nerve. - if the injection from the iliopsoas plane block spreads in the whole iliopsoas plane. - if the injection from the iliopsoas plane block spreads to the space between the pectineus and the external obturator muscles. - if the injection from the iliopsoas plane block spreads superficial to the iliopsoas muscle. - if the injection from the iliopsoas plane block spreads intraarticularly in the hip joint. - if the injection from the iliopsoas plane block spreads to the posterior part of the hip joint capsule - if / how often the injection from the iliopsoas plane block is inside the iliopectineal bursa medial to the target area.;Primary end point(s): Change of maximal force of knee extension from baseline to after nerve blockade.;Timepoint(s) of evaluation of this end point: 1 hour after nerve blockade | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1: Change of maximal force of hip adduction from baseline to after nerve blockade. 2: Change of maximal force of knee extension from baseline to after nerve blockade in the leg, where local anaesthetics are injected compared to the control leg. 3: Change of maximal force of hip adduction from baseline to after nerve blockade in the leg, where local anaesthetics are injected compared to the control leg. 4: Change of sensibility in the dermatome of the lateral femoral cutaneous nerve. 5: Change of sensibility in the dermatome of the femoral nerve. 6: Spread of contrast in the iliopsoas plane 7: Spread of contrast to the space between the pectinous and the external obturator muscles. 8: Spread of contrast to the superficial side of the iliopsoas muscle. 9: Intraarticular spread of contrast to the hip joint 10: Spread og contrast to the posterior side of the hip joint capsule. 11: Contrast in the iliopectineal bursa;Timepoint(s) of evaluation of this end point: 1-5: 1 hour after nerve blockade. 6-10: Evaluated by MRI-scan 5-60 minutes after nerve blockade. | — |
