We compared delayed distraction (DD) with immediate distraction (ID) in bone-lengthening. Open femoral diaphyseal osteotomy was performed on 24 three-month-old lambs, and external distractor fixators were applied. In the ID group (n 12), distraction commenced on the first postoperative day; in the DD group (n 12), distraction was delayed until the tenth day after surgery. In all the animals, th...

BACKGROUND Multiple cartilaginous exostoses cause various deformities of the epiphysis. In exostoses of the ulna, the ulna is shortened and the radius acquires varus deformity, which may lead to dislocation of the radial head. In this study, we present the results of exostoses resection, with correction and lengthening with external fixators for functional and cosmetic improvement, and preventi...

In this issue we are pleased to have a review of recidivism and the use of external fixators for control of pelvic haemorrhage in haemodynamically unstable patients. The accompanying editorial and article provide an insight into the lack of strong scientific evidence favouring modalities currently used in haemorrhage control in patients with major pelvic trauma. This indicates the need for a br...

This paper presents a comparative analysis of the biomechanical characteristics an external fixator with frame made two different materials (stainless steel and composite material) during anterior–posterior bending. Before test itself, representative configurations Sarafix were selected for application on lower leg upper extremities under designations B50 C50, which are most widely used in orth...

Introduction: To determine the stiffness characteristics of a new proposed hybrid fixator in comparison with more commonly used commercialized hybrid external fixators and idealized hybrid fixator. Materials and Methods: A prospective laboratory investigation was used to test the mechanical stiffness between the new proposed hybrid fixator (Figure 1) and the more commonly used hybrid external f...

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...
