Case Reports[Coincidence of Lipoma and Liposarcoma of the Right Hand in an 84-Year-Old Patient: A Case Report].
Summary. We report the case of an 84-year-old patient presenting with a painless tumor between the thumb and the index finger. MRI showed a clearly defined tumor of the thenar eminence with a centrally localized more solid structure. ⋯ Histologically, we found a lipoma with a centrally localized liposarcoma. We discuss the rare case of malignant transformation of a lipoma. In long-standing large lipomas we suggest regular controls by MR imaging.

[Treatment of Galeazzi's fracture - is the surgical revision of the distal radioulnar joint necessary?].
Fractures of the radial shaft associated with disruption of the distal radioulnar joint (DRUJ) are termed as Galeazzi-fractures. In Galeazzi's fracture, the aim of treatment is restoring the congruency of the joint and the stability of the DRUJ, thus preventing a loss of pronation or supination. ⋯ A stable and optimal reduction and a rigid internal osteosynthesis are requisites for healing of the radius fracture. Open reduction of the DRUJ is only indicated when soft tissue interposition prevents exact reposition. Surgical revision of the distal radioulnar joint was not necessary in our patients. Patients after Kirschner-wire fixation showed a diminished pro- or supination. To prevent Kirschner-wire failure, postoperative cast immobilization is indicated. Due to the retrospective nature of the study it is not definitely clear if Kirschner wire fixation is superior to immobilization.

Review[Carpal injuries associated with distal radius fractures. Diagnosis and therapy].
The frequency of carpal injuries associated with distal radius fractures is often underestimated. Diagnosis of such lesions can be difficult. ⋯ An early diagnosis of ligament injuries and instabilities can be obtained through cinematographic examination, whereas injuries to the TFCC are mainly diagnosed by MRI. Arthroscopy provides exact diagnosis as well as therapy, including arthroscopically controlled reposition of centrally depressed fragments of the articular surface of the radius and even treatment of TFCC lesions.

Comparative Study[MRI or arthroscopy in the diagnosis of scapholunate ligament tears in fractures of the distal radius?].
In a prospective study, 45 patients with fractures of the distal radius and radiologically suspected tears of the scapholunate interosseous ligament were examined. Magnetic resonance imaging was performed prior to wrist arthroscopy. The latter examination gave the definite diagnosis. ⋯ The use of intravenously applied contrast medium did not improve MRI accuracy. In conclusion, MRI is not recommended for the diagnosis of scapholunate ligament tears. Presumably, the results of MRI could be improved by a more sophisticated technique.

[Arthroscopic diagnosis of concomitant scapholunate ligament injuries in fractures of the distal radius].
To investigate the occurrence of carpal ligamentous injuries in patients with fractures of the distal radius, the results of 122 wrist arthroscopies were analysed within a retrospective study. Indications for arthroscopy included suspected carpal instability according to radiographic findings and/or the necessity for internal fixation of the radius fracture. Arthroscopy revealed acute scapholunate ligament tears in 84 patients. ⋯ There was no association between ligamentous lesions and carpal angles or fracture dislocation. Scapholunate ligament tears were most frequent in sagittal articular fractures. In these cases, wrist arthroscopy should be performed during operative treatment of the radius fracture to allow direct visualization and subsequent repair of ligamentous tears.
