Open palmar metacarpophalangeal joint dislocation: Case report, pathogenesis and literature review
Abstract:
We report the case of a 58-year-old man who sustained an open palmar dislocation of the fifth metacarpophalangeal joint of the little finger secondary to a bicycle accident with an uncommon presentation. These open dislocations have only been reported once in the literature. A palmar and dorsal approach had to be used to completely free the joint from incarcerations and allow complete reduction and repair of the damaged anatomical structures. We then discuss this particular type of dislocation, its pathophysiology and management.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
