Case Reports Comparative Study[MR imaging for the evaluation of accompanying injuries in cases of distal forearm fractures in children and adolescents].
The study was made to evaluate the role of MR imaging in pediatric distal forearm fractures by comparison with the findings of plain radiographs and MRI. ⋯ MRI plays an important role in the evaluation of acute pediatric wrist injuries. It allows a better evaluation of osseous lesions than plain radiographs. In our study, a tear of the triangular fibrocartilage complex accompanied distal radius fractures in 32 % of patients. Simultaneous rupture of the TFCC insertion in the fovea ulnaris and ulnar styloid fracture lead to destabilisation of the distal radioulnar joint (DRUJ).

Comparative Study[Multidirectional palmar fixed-angle plate fixation for unstable distal radius fracture].
Open reduction and internal fixation with plates is a valid treatment of displaced extra- and intra-articular distal radius fractures. This report presents our experience treating unstable distal radius fractures by using a multidirectional palmar fixed-angle plate system (Aptus(R) Radius 2.5 by Medartis). The subchondral support of the articular surface by fixed angle screws prevents secondary dislocation allowing early mobilisation. ⋯ The treatment of unstable distal radius fractures with this plate fixation provided stable internal fixation and allowed early function. Due to multidirectional angle fixation and two lines of cortical screws it is possible to achieve an optimal restoration. The fixation of the central articular surface is guaranteed by the distal line, the dorsal subchondral support by the proximal line.

Comparative Study[Acceptance of patient-related evaluation of wrist function following distal radius fracture (DRF)].
Outcome evaluation after distal radius fractures is mainly based on wrist function and radiological parameters, while measuring patient satisfaction seems to be more difficult. The purpose of this study was to assess different subjective features with regard to patient satisfaction for wrist healing, activity and participation. ⋯ All questions were of a high validity and significance to determine subjective outcome after distal radius fractures. Patient acceptance was significantly different for questions, and subjective wrist comfort depended on age. For ages 50 to 69, additional questions in terms of employment situation and recreational function could be incorporated. Only about half of the questions correlated with radiological parameters of distal radius malunion. Eight questions showed both high acceptance and high correlation with radiology. Standardised measurements of range of motion and power, as well as radiology features and subjective questions of high acceptance and radiology relevance are essential for a wrist-specific questionnaire.

Comparative Study[Limits of palmar locking-plate osteosynthesis of unstable distal radius fractures].
The use of locking plate systems in the treatment of distal radius fractures has increased during the last years. In the presented study our experience and results after palmar plating of dorsal dislocated distal radius fractures are analysed and presented. Besides the functional and radiological results, the potential surgical risks and the observed complications are discussed. ⋯ Favourable indications for palmar locking plate osteosynthesis are A2, A3, C1 and C2 fractures with big distal fracture fragments. In these cases, additional bone grafting is not needed. In very distal fractures, multidirectional plate-systems are advantageous. Multifragmental C3 fractures show a high complication rate. Additional bone grafting for the metaphyseal defect should be considered.

[Sagittal wrist motion following dorsal radiocarpal fracture dislocations].
Radiocarpal fracture dislocation is a rare, complex injury characterised by dislocation of the radiocarpal joint with avulsion of the dorsal or palmar cortical margin of the distal radius. To evaluate the sagittal motion at the radiocarpal and midcarpal levels following dorsal radiocarpal fracture dislocation (Moneim type I) nine cases were investigated clinically and radiologically. ⋯ Operative treatment of dorsal radiocarpal fracture dislocation using a bilateral approach led to satisfying results in eight of nine cases with decreased but radiologically evaluated sagittal motion of the proximal row.
