Optimal prehospital and clinical management of patients with severe pelvic trauma is controversial. Prospective evaluations of different treatment strategies have not been performed and treatment is currently not evidence-based. The purpose of the present study was to develop a porcine model of reproducible severe pelvic trauma for subsequent laboratory trials. ⋯ The present model was able to create reproducible unstable pelvic fractures and can be used for controlled laboratory trials to study the management of patients with pelvic fractures.

The possibility of occult hip fracture in older patients after a fall is a common problem in emergency and orthopaedic departments. Magnetic resonance imaging (MRI) scanning is the best investigation, but is expensive and may be difficult to obtain. The value of various clinical signs to determine which patients are at risk of occult hip fracture has not been reported. ⋯ Predictive values remained the same when both factors were considered together. Patients who were independently mobile before the fall and who do not have pain on axial compression of the limb are less likely to have a fracture, but these signs alone or in combination do not exclude a fracture. The clinical signs investigated cannot distinguish between patients with and without a hip fracture, and MRI scanning is necessary to establish whether some patients have an occult fracture.
