External pin fixation for unstable Colles' fractures.
During a five-year period, a double-pin Roger Anderson apparatus, with pins perpendicularly placed in the second and third metacarpals and in the distal part of the radius, was applied in 130 patients with an unstable Colles fracture. Sixty of the 130 were followed for two years. Shortening was limited to a median of two millimeters and dorsal angulation, to a median of 3 degrees. Wrist dorsifl...
متن کاملSupraacetabular external fixation for pain control in geriatric type B pelvic injuries.
UNLABELLED PURPOUSE OF THE STUDY: Pelvic ring fractures in the geriatric population are of increasing frequency. Often insufficiency fractures or occult fractures are described. With a classical injury mechanism the majority of these injuries are the result of a low energy trauma, typically a fall from standing or during walking.Clinically, many patients report immediate anterior groin pain but...
متن کاملThe care of pin sites with external fixation.
Two protocols for the operative technique and care of the pin-site with external fixation were compared prospectively. There was a total of 120 patients with 46 in group A and 74 in group B. Infection was defined as an episode of pain or inflammation at a pin site, accompanied by a discharge which was either positive on bacterial culture or responded to a course of antibiotics. Patients in grou...
متن کاملBiomechanical analysis of four external fixation pin insertion techniques
Having multiple external fixation pin designs and insertion techniques has led to debate as to which combination creates the stiffest construct. This study sought to biomechanically evaluate construct strength using self-drilling (SD) and self-tapping (ST) pins inserted with either bicortical or unicortical fixation. SD and ST 5.0 mm stainless steel pins were used in combination with bicortical...
متن کاملAvoidance of external fixation pin induced rotational stiffness in the forearm; a cadaver study of soft tissue displacement relative to the varying position of radius and ulna fixation
INTRODUCTION Stiffness of forearm rotation secondary to transfixion pin sites is a frequent complication of external fixation. Conventional surgical atlases do not consider the effect of rotation on skin displacement and thus do not provide a comprehensive answer. We asked: (1) in what locations in the forearm is soft tissue displacement relative to the ulna and radius least during rotation; (2...
