An Evaluation of the Reliability of Manual Landmark Identification on 3D Segmented Wrists.

Background: Three-dimensional (3D) preoperative planning is increasingly used in orthopaedic surgery. Two-dimensional (2D) characterization of distal radial deformities remains inaccurate, and 3D planning requires a reliable reference frame at the wrist. We aim to evaluate the reliability of the determination of anatomical points placed manually on 3D models of the radius to determine which of those points allow reliable morphometric measurements.

An artificial intelligence based on a convolutional neural network allows a precise analysis of the alignment of the lower limb.

Purpose: The objective of this study was to develop a numeric tool to automate the analysis of deformity from lower limb telemetry and assess its accuracy. Our hypothesis was that artificial intelligence (AI) algorithm would be able to determine mechanical and anatomical angles to within 1°.

Methods: After institutional review board approval, 1175 anonymized patient telemetries were extracted from a database of more than ten thousand telemetries.

Sporadic Schwannomatosis: A Systematic Review Following the 2005 Consensus Statement.

Aims:  To identify the frequency of reports of sporadic schwannomatosis, the types of patients affected, and the nerves affected.

Patients And Methods:  We identified all case reports and case series that reported on patients with sporadic schwannomatosis according to established criteria.

Results:  The initial search yielded 1,597 studies, of which 15 were included.

[Sprain of the thumb metacarpal-phalangeal with lesion of the ulnar collateral ligament].

The sprain of the thumb metacarpal-phalangeal joint must be treated in an adapted way in order to avoid chronic laxity. The comparative and bilateral clinical exam is the main element that will allow to detect laxity. In the case of non laxity, a conservative treatment with a splint makes sense.
