The authors present an inovated Charnley's operation method of ankle arthrodesis by a modified anterior approach and method of external fixation. They evaluate a group of 26 patients operated on the period from 1993 to 1996. The patients were operated on 14 cases for purulent ankle arthritis, in 7 c …

2024年10月23日 · Many studies have demonstrated fusion by external fixators because infection is the most common indication of this procedure. We studied knee arthrodesis using Charnley’s compression clamps which are easy to apply and economical. A prospective observational study was conducted on 15 patients for 18 months.

Knee fusion using circular external fixation is a reliable surgical option for complex knee problems especially in infected failed revision total knee replacements. Keywords: Knee, Fusion, Arthrodesis, Ilizarov, External fixation, Hexapod external fixator. Introduction

2016年2月20日 · In this series, we used a monorail external fixator to achieve fixation and compression across the knee for arthrodesis in patients with either post-traumatic or post-septic sequelae (Figs. 1, 2). Immediate post-operative antero-posterior plain radiographs showing knee arthrodesis performed with an anterior monorail fixator.

The classic indications for the external fixator are compression arthrodeses (Charnley) and certain open fractures (Hoffmann). Like the medullary nail, the external fixator can be useful in unusual situations by virtue of its special indications and operative technique.

Introduction: Extra-focal or external fixation is the method of fracture fixation through the healthy part of the bone using pins or wires. Objective: The aim was to determine which external splints (Ortofix, Mitković, Charnley and Ilizarov) had the best biomechanical properties in primary stabilization of spiral, transverse and commutative ...

2014年7月1日 · Sir John Charnley first described compression arthrodesis in 1951 using an external compression device transfixed on either sides of the ankle (5). The inability to resist rotatory forces and the high nonunion rates using Charnley's external compression device led to modification of external fixation techniques 6, 7.

External fixation can be used to augment or provide primary stabilization for arthrodesis of the midfoot. The indications for external fixation in arthrodesis of the midfoot include Charcot arthropathy, treatment of ongoing sepsis or osteomyelitis, and nonunions and in osteopenic patients in whom internal fixation would be difficult . Patients ...

Today's standard applications of external fixation for tibial fractures is a unilateral fixator, using Schanz screws. The pin-bone interface is the most critical site of all external fixation. By avoiding heat necrosis (low temperature drilling) and preventing micro motion at the pin-bone interface (by applying bending- or more recently radial ...

The external fixator is a device that is used in bone surgery, war and peace trauma. It is used for the fixation of bone fragments, using nee-dles and pins that pass through the parts of the skeleton fixed for the construction of exter-nal splints. This therapeutic method with an external fixator is called outer fixation. It can
