Carpometacarpal (CMC) joint fractures-dislocations are rare due to the complex structure of the carpal bones and strong ligamentous support; while the clinical image is usually "noisy," they present significant management challenges due to the unstable nature of the injury. These injuries are typically caused by high-energy trauma and frequently result in dorsal dislocations. Treatment requires a careful balance between the immobilization and surgical restoration of the anatomical alignment to prevent complications.

A comparative approach to the microstructure in the carpus and tarsus in anurans.

Dev Growth Differ

Despite the significant literature about morphological features of limb skeletons involved in tetrapod limb evolution, some questions about carpal and tarsal elements remain. In anurans, the ecomorphological and biomechanical approaches studied long hind limbs (to jump) and forelimbs (to land) and emphasized the role of the long bones in locomotion but disregarded what happens with the nodular elements of the carpus and tarsus. Here, we present a comparative study of nodular elements of the carpus and tarsus in anurans based on whole-mount specimens stained with Alcian Blue (cartilage) and Alizarin Red S (bone and calcified cartilage).

Background: Musculoskeletal injuries (MSI) are a major concern in the horse racing industry, often leading to career-ending outcomes. Contributing factors include conformation, limb and joint defects, hoof structure, age, and hard track surfaces.

Objectives: This study aimed to evaluate the distribution of MSI in Thoroughbred and Arabian racehorses during racing and training, categorised by breed and track surface.

Purpose: To evaluate the rate of missed scaphoid fractures on follow-up computed tomography (CT) for suspected occult scaphoid fracture after normal radiography with residual radial-sided wrist pain.

Methods: In a retrospective analysis, wrist CT during a five-year period was analyzed. The CT examinations and radiological reports were re-evaluated.

Pediatric Scaphoid Nonunions: Does Insurance Status Play a Role?

J Pediatr Orthop

February 2025

Orthopaedic Surgery and Sports Medicine, Akron Children's Hospital, Columbus, OH.

Article Synopsis
  • The study aimed to assess how insurance status and socioeconomic factors influence treatment timelines and outcomes for scaphoid nonunions in children.
  • A review of patient charts from a pediatric hospital found no significant differences in treatment delays or postoperative outcomes between privately insured and underinsured patients.
  • Results indicated comparable recovery outcomes, including rates of fracture union and levels of pain or mobility issues, regardless of insurance status, suggesting equitable access to care across both groups.
