Brief summary
Pelvic ring fractures in the elderly are associated with high morbidity during standard conservative treatment due to immobility. Furthermore the risk of long term dependence even after the fracture has united is high. In analogy to the treatment of hip fractures in a similar patient population, patients might benefit from surgical treatment due to a reduction in pain and early mobilization.
Detailed description
Comparison of surgical vs conservative treatment with respect to mobility, pain, morbidity and mortality.
Interventions
PROCEDUREexperimental intervention surgery
Patients are placed supine on the carbon table. Screw paths are planned on a spiral CT scan from the sacrum on transversal slices, two Kirschner-wires 2.5 mm in diameter are introduced into the iliac bone through a stab incision and advanced into the ilio-sacral joint, through the lateral part of sacrum into the first and second sacral body, through the contralateral lateral part of the sacrum and exiting the contralateral iliac bone through the sacra-iliac joint with aid of CT-guidance. Over the Kirschner-wires 7.0 mm cannulated screws are introduced and the Kirschner-wires withdrawn. Several low-dose computer tomography scans are performed to secure the correct position. Total radiation dose is 300 mille gray square centimetres (mGycm).
PROCEDUREcontrol intervention
Mobilization guided by our physiotherapists. Full weight bearing is allowed. Analgetic treatment with metamizol, ibuprofen or paracetamol to the attending physicians discretion under regular surveillance laboratory values and/ or morphine or methadone. Patients will be treated with an individually based approach, if necessary involving our anesthesiologic pain service. Thrombo-embolic prophylaxis with a low molecular weight heparin or rivaroxaban for 6 weeks unless there is an indication for oral anticoagulation. All patients will be followed up by the Geriatric Fracture Center considering osteoporosis, fall prophylaxis, malnutrition and delirium. For the duration of the study the patients will not receive Parathyroid Hormone Substitution or Phosphonates.

Exclusion criteria
* Refusal of consent by the patient or legal representatives to participate in the study * Other fractures or * Unstable pelvic fracture (type B or C according to classification of 'Arbeitsgemeinschaft für Osteosynthesefragen' (AO)/OTA) requiring surgical stabilisation after high- or low-energy trauma * Suspicion of a pathological fracture in the context of known or unknown malignancy * Previous surgery of the pelvis with metal obstructing the planned paths of the ilio-sacral screws * Symptomatic low back pain with morphological changes, i.e. intervertebral disc displacement, neoplasm metastasis in the axial skeleton, spinal stenosis, vertebral fracture, spondylarthropathy etc. * Comorbidity that precludes undergoing general or spinal anaesthesia * Pre-trauma mobility status that precludes achieving a post-trauma mobility status enabling the patient to perform the timed up and go test (e.g. patient being in a wheel chair)

Primary
| Measure | Time frame | Description |
|---|---|---|
| Mobility at 3 weeks post-diagnosis | 3 weeks post-diagnosis | Quality of mobilization will be compared using the TUG test. The primary endpoint is TUG at 3 weeks following diagnosis (+/- 3 days) all TUG measurements are assessed by the study nurse. |

|---|---|---|
| Activities of Daily Living (ADL) at 4-7 days after diagnosis | 4-7 days after diagnosis | Functional recovery will be measured using the ADL score. |
| Activities of Daily Living (ADL) at 3 weeks | 3 weeks | Functional recovery will be measured using the ADL score. |
| Activities of Daily Living (ADL) at 3 months | 3 months | Functional recovery will be measured using the ADL score. |
| Activities of Daily Living (ADL) at 12 months | 12 months | Functional recovery will be measured using the ADL score. |
