BACKGROUND We have recently developed a subcutaneous anterior pelvic fixation technique (INFIX). This internal fixator permits patients to sit, roll over in bed and lie on their sides without the cumbersome external appliances or their complications. The purpose of this study was to evaluate the biomechanical stability of this novel supraacetabular pedicle screw internal fixation construct (INF...

BACKGROUND Customized foot plates attached to the foot ring of an ankle-spanning circular external fixator present a unique opportunity for patients undergoing complex lower-extremity limb salvage to participate in highly advanced weight-bearing physical therapy. The purpose of this study was to identify the rehabilitation capabilities afforded by this external fixator modification. METHODS S...

UNLABELLED PURPOUSE OF THE STUDY: Pelvic ring fractures in the geriatric population are of increasing frequency. Often insufficiency fractures or occult fractures are described. With a classical injury mechanism the majority of these injuries are the result of a low energy trauma, typically a fall from standing or during walking.Clinically, many patients report immediate anterior groin pain but...

PURPOSE Femoral lengthening using a circular or mono-lateral frame is a commonly used technique. Fracture at the site of the regenerate bone is a major concern especially following removal of the external fixator. This aim of this study was to assess the rate of fracture of the regenerate bone in this single surgeon series of paediatric patients and determine potential risk factors. METHODS R...

Very little is known about the influence of the mechanical environment on the healing of large segmental defects. This partly reflects the lack of standardised, well characterised technologies to enable such studies. Here we report the design, construction and characterisation of a novel external fixator for use in conjunction with rat femoral defects. This device not only imposes a predetermin...
