[The role of imaging in the assessment of vascularity at hand and wrist].

The viability of the bone is compromised in two main situations at the wrist: Kienböck's disease and scaphoid nonunion with avascular necrosis. Plain radiography and CT allow an accurate anatomical approach of morphological changes associated with avascular necrosis of the lunate and the scaphoid fracture with complications. CT is readily available to detect nondisplaced fractures.

[MRI study before and after extracorporal shock wave therapy in calcifying tendinitis of the shoulder].

Purpose: Extracorporal shock wave therapy has recently been proposed with good results (70%) for treatment of persistent painful calcifying tendinitis of the shoulder. The aim of this study was to evaluate the early impact of shock wave therapy on the anatomic structures of the shoulder.

Materials And Methods: Eight patients (7 women and 1 man, with mean age of 48 years) were prospectively followed up after undergoing shock wave therapy (1500 pulses with 0.

[Imaging of complications following hip arthroplasty].

Acute complications include fractures and prosthesis dislocations. Most chronic complications involve mechanical or septic loosening and aggressive granulomatosis. Greater trochanteric pseudarthrosis, periprosthetic soft tissue ossifications or prosthesis conflict with the psoas muscle can also be responsible for groin pain.

[Neurotrichinosis: a case report with MRI evaluation].

Neurological complications are rare in trichinosis. A case of trichinosis involving the central nervous system documented by MRI is presented. To our knowledge, only three cases of neurotrichinosis with MRI abnormalities have been already reported.
