Essex-Lopresti injuries are often unrecognized acutely with resulting debilitating adverse effects. Persistent axial forearm instability may affect load transmission at both the elbow and wrist, resulting in significant pain. In the setting of both acute and chronic injuries metallic
Radial head fractures are among the most common fractures around the elbow.

Background. Comminuted radial head fractures are challenging to treat with open reduction and internal fixation. Complicating matters further, radial head fractures are often associated with other elbow fractures and soft tissue injuries.

Aims: The purpose of our study was to determine the radiographic anatomy of the proximal radius in three different views in order to identify that position, which has the smallest value for the angle between the axis of forearm rotation (AFR) and the radial neck axis (RNA). It is our hypothesis that such a position should offer the optimal situation for the radial neck cut in

The significance of matching radius of curvature of the radial head implant and the capitellum in implant selection is evaluated. A mismatch of radius of curvature could lead to point loading, reducing contact area, creating large contact stresses, resulting in arthritis, pain, and other complications. Radial head (RH) implant size is chosen by reconstruction outside of the radiocapitellar joint capsule measuring the RH diameter and length, which is replicated for implant selection. RH radius of curvature (RC) is rarely part of the decision although important in determining contact area.Summary
Introduction
Consistent load distributions with over-sizing of radial head implants show minimal variance in interosseus ligament (IOL) and triangular-fibrocartilage complex (TFCC) tension, both of which are essential in distribution of load at the elbow. Introduction:Changes in loading distribution at the elbow have not been studied with radial head (RH) arthroplasty. Difficulty arises concerning distribution variability between loading methods and magnitudes, and with implant oversizing. RC joint capsule were exposed using the Kocher approach in seven fresh-frozen cadaver Humeri. Specimens were loaded axially in an MTS machine with humeri at 90° and wrist neutral. The arms were cycled in load control between 13N–130N until steady-state was reached for each trial. After loading in neutral, the arms were rotated to 60° supination (60S) and 60° pronation (60P), the test repeated. The radial head was excised and Co-Cr implant inserted. Sizings 0mm, +2mm, +4mm were simulated using 2mm plastic spacers on the stem. A Tekscan pressure map transducer at RC recorded loading. The recorded Tekscan loads were organised according to sizing (native, 0mm, +2mm, +4mm) for each specimen. The max/min load values were recorded and the difference, ΔL was calculated. The Max and ΔL values from each sizing were percentage paired with the respective native value. The ΔL values were used to discern load distribution. A linear regression was done using the RC loading plotted against the applied load to visualise the change of load distribution with changing applied loads. Data was analyzed using one-way analysis of variance.Summary

The treatment of comminuted fractures of the radial remains controversial. When preservation of the radial head mechanics is required, the choice between open reduction and internal fixation and
Purpose: Metal
Where reconstruction is deemed impossible, excision of the radial head has been the mainstay of treatment for shattered radial head and neck fractures. While some patients seem to do well after the procedure, some develop progressive instability and pain because of proximal translocation of the radius. We looked at a new procedure in which a metal radial head is inserted to provide greater stability after the excision. Historically silicone prostheses have been used, but these were found to fail dramatically after a time. We recruited 11 patients requiring
