Surgical Management

Repair of the injured collateral ligaments and volar plate in the acute setting does not improve the outcome and may result in increased stiffness of the joint. Acute surgical intervention is reserved for cases of incongruent reductions, generally from tissue interposed within the joint. Stern has described a Stener-type lesion after lateral dislocation of the PIP joint in which the collateral ligament was incarcerated between the lateral band and the central slip, necessitating operative intervention. Although this lesion would seem more likely in volar rotatory dislocations, in which the triangular ligament between the lateral band and central slip is ruptured, it may be seen in true lateral dislocations.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
