Re-establishing normal osteoarticular anatomy, and early mobilization are the principal elements in the successful treatment of fractures of the base of the first metacarpal. To achieve these goals in thirty-nine fractures rigid fixation was obtained by screw alone, or by a mini-plate. Seven Bennett's fractures have been treated by screw fixation when the size of the fragment has made it possible. Extra-articular fractures have been treated, either by screw alone, in oblique fractures (7 cases). Or by mini-plate, T or L shaped, in transverse fractures (23 cases). The use of these techniques have been extended, to comminuted fractures but is not used in Bennett's fractures when the fragment is too small to allow the screw to be anchored in it without its being shattered.

When infants are admitted to the hospital with skull fractures, providers must distinguish between cases of accidental and abusive head trauma. Limited information about the incident is available in such cases, and witness statements are not always reliable. In this study, we introduce a novel, data-driven approach to predict fall parameters that lead to skull fractures in infants in order to aid in determinations of abusive head trauma.

Background: Clavicle fractures associated with ipsilateral coracoid process fractures are very rare, with limited literature reporting only a few cases. This study reports on 27 patients with ipsilateral concomitant fractures of the clavicle and coracoid process who were followed for more than 12 months.
Material And Methods: This retrospective study reviewed the charts of skeletally mature patients with traumatic ipsilateral clavicle and coracoid process fractures treated at the authors' institution.
Purpose: Previous studies have shown that subtrochanteric femoral fractures treated with intramedullary nails might lead to varus-procurvatum malalignment. Similar results have been reported when using antegrade intramedullary lengthening nails (ILNs). The purpose of our study is to examine if antegrade telescoping intramedullary lengthening nails lead to varus-procurvatum malalignment of the proximal femur and what are possible predictors of that shift.

Introduction: Impact microindentation (IMI) measures bone material strength index (BMSi) in vivo. However, its ability to predict fractures is still uncertain. This study aimed to determine the association between BMSi and 10 year fracture probability, as calculated by the FRAX algorithm.

Objective: This study is aimed at evaluating the distribution of metastatic bone disease (MBD), with a particular focus on the humerus, and its association with pathological fractures. Factors for contributing to the underestimation of fracture risk were assessed, including their impact on surgical management.
Materials And Methods: We retrospectively reviewed patient records of patients undergoing surgical treatment for MBD at our institution between 2005 and 2023.
