Limping and groin pain can issue diagnostic problems during late pregnancy. Differential diagnosis of two idiopathic syndromes, transient osteoporosis and osteonecrosis of the femoral head, is made possible by MRI in the early stages. This case is reported to demonstrate the need to distinguish between those syndromes early so as to prevent further joint damage.

Unstable fractures of the posterior pelvic ring are frequently combined with severe hemorrhage. In 80% of cases the bleeding originates in the ruptured presacral venous plexus or the fracture itself. Arterial bleeding is less common. The pelvic clamp introduced by Ganz can make it possible to stabilise the pelvis, with subsequent compression of the fracture planes and reduction of the intrapelvic volume in such cases, so improving the prognosis. Use of the pelvic clamp can be integrated into the management in the emergency room with no problem. ⋯ In the hands of an experienced and practised user application of the pelvic clamp is a safe method for emergency stabilisation of the posterior pelvic ring in polytraumatised patients, even without blood volume control. Problems can be solved and do not generally mean the pelvic clamp cannot be used. The immediate radiological check (e.g. during the emergency CT -scan performed for primary diagnosis) is a must, however.
