National, randomized, open, parallel, multicenter clinical trial of two comparison groups that will evaluate the feasibility of a strategy based on a diagnostic test to shorten the surgery time in antiaggregated patients with proximal femur fracture.
The experimental group will undergo surgery as soon as platelet aggregability, according to the PLATELETWORKS® method is correct within 24-48 hours.
The control group will undergo surgery according to the usual practice of the center taking into account the safety time of the antiplatelet agent.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental group | Experimental | In this group the platelet aggregability will be evaluated and if it is normal, the surgery will be performed within 24-48 hours. If it is not normal, the evaluation of platelet aggregability will be repeated daily until the third day or until it is normalized if it is earlier. If at the third day is not normalized, it will proceed as with the control group, which will take into account the safety time of the drug. |
|
| Control group | No Intervention | The control group will wait for the safety time of the drug according to the usual practice of the center. |

| Platelet function assay | Diagnostic Test | Plateletworks is an in vitro diagnostic screening assay for the determination of % platelet aggregation or % platelet inhibition. It will be used to measure platelet function after withdrawal of the antiplatelet agent. If there are more than 80,000 functional platelets, the patient will be operated on within the next 24 hours. |
| Measure | Description | Time Frame |
|---|---|---|
| Time from emergency admission to surgery | Time from emergency admission to surgery will be measured in hours | Up to 120 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Bleeding | Total blood loss calculated by Nadler's formula from date of surgery until date of discharge | Through hospitalization, an average of 5 days |
| Need for blood transfusion | Need for blood transfusion during hospitalization and transfused units |
