The Ortho-SUV frame (OSF) is a novel hexapod circular external fixator which draws upon the innovation of the Ilizarov method and the advantages of hexapod construction in the three-dimensional control of bone segments. Stability of fixation is critical to the success or failure of an external circular fixator for fracture or osteotomy healing. In vitro biomechanical modelling study was perform...

This is a report of the experience we have gathered in the application of the pinless fixator in cases of tibial fracture with soft tissue damage. In the Berufsgenossenschaftlichen Unfallklinik Ludwigshafen (Clinic for Trauma Surgery) 12 diaphyseal fractures of the tibia were stabilized with the pinless fixator in 1991. In all cases, conversion to an intramedullary nail was intended from the ve...

Objectives. The aim of the study was to investigate the results of patients with isolated length discrepancy between ulna and radius who underwent distraction osteogenesis with unilateral external fixator. Material and Methods. A patient with ulna shortening due to multiple enchondromatosis, a patient with ulna shortening due to ulnar club hand, and a patient with radial shortening due to radia...

A 50-year-old man presented with severe back pain and tenderness throughout the lumbar area after falling from a ladder. He had an unstable type-B burst fracture, with a spinal canal narrowing of 36% and an anterior height loss of 65%. His lower-limb neurological function was intact. An Ilizarov external spinal fixator was used; the pedicular half pins were inserted into the bilateral T11, T12,...

The aim of this study was to evaluate the effectiveness of unilateral external fixator as primary and definitive treatment for open tibial fractures, fractures with severe soft tissues injuries, threatened compartment syndrome, and in multiply injured patients. Two hundred and twenty-three tibial shaft fractures (212 patients) were treated. In open fractures, union was achieved in 25 weeks, whi...

Pin-tract infection (PTI) is the most commonly expected problem, or even an almost inevitable complication, when using external fixation. Left unteated, PTI will progress unavoidably, lead to mechanical pin loosening, and ultimately cause instability of the external fixator pin-bone construct. Thus, PTI remains a clinical challenge, specifically in cases of limb lengthening or deformity correct...

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...

INTRODUCTION External fixation is the primary choice of temporary fracture stabilisation for specific polytrauma patients. Adequate initial fracture healing requires sufficient stability at the fracture site. The purpose of this study was to compare the rigidity of the Dynafix DFS(®) Standard Fixator (4 joints) with the Orthofix ProCallus Fixator(®) (2 joints), which differ in possibilities for...

We present a case of 16-year-old male with Salter-Harris type II physeal slip the distal femur managed closed reduction and K wire clamp-based external fixator. Knee range motion exercises were initiated after one week. The union was observed at 10 weeks, implant removal done on an outpatient basis. At year follow-up, patient had good clinical radiological outcomes. K-wire-based fixator frame i...
