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 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 کاملBone-FixES: An External Skeletal Fixation Expert System
Bone-FixES is an expert system currently under development to aid student and clinical practitioner decision making for construction of external skeletal fixation devices. External skeletal fixation devices (also called fixators) are used to secure broken bone segments during the healing process. For teaching, Bone-FixES will be used to provide feedback to students given a clinical scenario and...
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 کاملParametric analyses of pin-bone stresses in external fracture fixation devices.
Problems occurring in the use of external fixators for bone fractures include pin-bone interface necrosis, infection, and loosening. These may be initiated and enhanced by pin-bone interface stress levels. Based on stress data from finite element method (FEM) models, an analytical "closed-form" model of the local pin-bone configuration in long-bone fracture fixation is developed. This model is ...
