The pin-bone interface is the least stable component of the external skeletal fixator. Concerns exist regarding the ability to obtain adequate implant purchase in poor quality bone. Consequently, reduced bone quality has been viewed as a contra-indication for the use of external skeletal fixators. The aim of this study was to investigate the holding power of two different fixator pin designs in...

OBJECTIVES This study aims to evaluate the outcomes of the Ilizarov external fixator for the correction of complex foot deformities. PATIENTS AND METHODS Between January 2000 and September 2005, 29 feet of 25 patients (18 males, 7 females; mean age 13.7 years; range 5 to 24 years) who were applied Ilizarov external fixators due to complex foot deformities in our clinic were prospectively anal...

BACKGROUND Intramedullary Ender nailing in intertrochanteric fractures was very popular in the past. However, this method has fallen in favor over time, due to complications. The purpose of this study was to evaluate results with this method and possible ways to prevent these complications, including the use of unilateral fixators to support the Ender nails. METHODS This technique (Ender nail...

Tissue engineering has recently gained popularity as an alternative to autografts stimulate bone tissue regeneration through structures called scaffolds. Most of the in vivo experiments on long-bony defects use internally-stabilized generic Despite wide variety computational methods, a standardized protocol is required optimize ceramic scaffolds for load-bearing bony stabilized with flexible fi...

PURPOSE To enhance bone healing through controlled interfragmentary movements, numerous experiments have been conducted in animal models employing external fixation devices to apply mechanical stimulation to the fracture site. However, the efficacy of these fixators has been questioned. On the other hand, intramedullary nailing is a widely established clinical practice for reducing closed tibia...

BACKGROUND Infection in orthopedic surgery is a disaster both for the patient and surgeon. Although its incidence has been reduced due to modern theatre facilities and aseptic measures but in developing countries its prevalence is still high. It is better to prevent infection rather than to treat it. The objective of this study is to know the frequency of infection in orthopedic implant surgery...

A sagittal split fracture of the C1 lateral mass is an unstable subtype of C1 fractures and has a high propensity for developing late deformities and pain with nonoperative management. A primary internal fixation of this type of fracture has been recently described with good clinical outcomes and preservation of motion. We present a modified technique of primary internal fixation using an obliq...

Diaphyseal fractures of the III metacarpal bone represent 22% of all fractures of the long bones in horses. Treatment of such cases is difficult. The most popular solution used in these types of fractures is two plates applied directly to the bone surface, but they are not applicable on contaminated and infected fractures. External fixators are quite commonly used in human medicine, although in...

Unlike external fixators, the use of solid intramedullary lengthening nails is restricted to defined anatomical preconditions, such as an adequate bone length. Furthermore, all deformity corrections except the lengthening procedure have to be implemented intraoperatively and cannot be adjusted postoperatively. Conversely, even complex deformity corrections can be performed using intramedullary ...
