Hand Fracture

Abstract

Each metacarpus consists of three parts: a body, head, and base. The base articulates with the carpus and with the adjoining metacarpal bones. The body is curved in the form of a prismoid; thus convex in the longitudinal direction posteriorly. There is a tubercle on either side of the head for the attachment of the collateral ligaments of the metacarpophalangeal joint. Based on the OTA classification, metacarpal fractures are classified as the following: metacarpal proximal (16.73% of all metacarpal fractures) and distal (15.93% of all metacarpal fractures) extra-articular fracture, diaphysis non-comminuted fracture (43.33% of all metacarpal fractures), metacarpal proximal (8.24% of all metacarpal fractures), distal (2.48% of all metacarpal fractures), partial articular fracture and diaphysis wedge comminuted fracture (6.12% of all metacarpal fractures), metacarpal proximal (2.78% of all metacarpal fractures) and distal (1.42% of all metacarpal fractures), complete articular fracture and diaphysis comminuted fracture (2.78% of all metacarpal fractures).
