The Transverse Sigmoid Notch Morphology Unravelled.

Several studies have described pathology in relation to transverse sigmoid notch morphology, using the Tolat transverse sigmoid notch classification. It is believed that the entire shape of a sigmoid notch can be described using Tolat sigmoid types. We hypothesised that the determination of the sigmoid notch shape (SNS) depends on the level of the transverse CT plane on the axial axis of the distal radius.

Anterior locking plate fixation versus cast immobilization for acceptably reduced extra- articular distal radial fractures: long-term follow-up of a randomized controlled trial.

This study reports the long-term results of a randomized controlled trial comparing anterior locking plate fixation with cast immobilization for extra-articular distal radial fractures. After 5.3 years of follow-up, no clinically relevant functional differences were found.

Concomitant ligament injuries can be left untreated during surgery of distal radial fractures.

Instability of the distal radioulnar joint and scapholunate dissociation may cause pain, functional impairment and subsequent arthrosis. There is no consensus about whether these injuries should be treated acutely in patients undergoing surgery for distal radial fractures. We conducted a prospective cohort study to determine whether concomitant distal radioulnar joint instability or scapholunate dissociation negatively influence patient-related outcomes in these patients.

Quantitative Analysis of the Volar Ulnar Corner of the Distal Radius: A Reference for Intraoperative Distal Radius Fracture Reduction.

Purpose: The reduction of distal radius fractures using volar locking plate fixation can be performed by securing the plate to the distal fragments and then levering the plate to the radial shaft. Oblique placement of the plate on the radial shaft may lead to malreduction. The aim of this study was to evaluate parameters that can be used for the assessment of intraoperative distal radius fracture reduction using "distal-first" volar plate fixation, especially the geometry of the ulnar corner.

Comparison of extra-articular radiographic parameters of distal radius fractures on plain radiographs and CT scans.

The aim of this study was to compare extra-articular radiographic parameters of distal radial fractures measured on plain radiographs and CT scans. Two researchers independently measured four extra-articular radiographic parameters (dorsal tilt, carpal alignment, radial inclination and ulnar variance) on both radiographs and CT scans in 85 patients. Inter-observer reliability for both techniques was assessed, along with the agreement between CT scans and radiographs using the intraclass correlation coefficient and Bland-Altman plots.

[A man with a red umbilicus].

A 76-year-old man was sent to the dermatology department because of a red, sore belly button since 3 weeks. Based on histology, a CT-scan and increased Cancer Antigen 19-9 levels, this was interpreted as a pancreas carcinoma metastasis. This type of metastasis is also called a 'Sister Mary Joseph's nodule'.
