    Notes: Summary.  Severe factor IX deficiency is an X-linked disorder which gives rise to spontaneous and often life-threatening bleeds. The major source of morbidity worldwide is recurrent haemarthroses, giving rise to joint destruction and deformity. However, the incidence of spontaneous haemarthroses has decreased since the advent of prophylactic home-based, on-demand, early replacement therapy.We present the case of a non-ambulant, 13-year-old boy from Chernobyl, who did not have access to this type of treatment, and whose deformity was managed using the Ilizarov external fixator.An external fixator was applied under general anaesthetic in theatre. Haemostasis was achieved by maintaining his FIX levels at 1.0 IU mL−1 pre- and post-operatively. Three months later, the fixed flexion deformity had been reduced from 50 to 5°. Four months postsurgery, this boy was walking freely without pain. There was no peri- or post-operative bleeding or joint swelling.

    Notes: Abstract Simultaneous ipsilateral fracture of the elbow and forearm – floating elbow – is an uncommon injury. During a 7-year period we prospectively followed 12 children who presented with completely displaced supracondylar fractures of the humerus associated with a forearm fracture of the same limb. All patients underwent emergency operative reduction and percutaneous K-wire stabilisation. At a minimum of 18 months, all patients were assessed clinically and radiologically and the results evaluated according to a conventional scoring system. Ten patients had good or excellent outcomes, and there were two fair results. The incidence of open fractures and nerve injury and the need to perform an open reduction were higher than those recorded for isolated supracondylar fractures. The floating elbow is an indicator of a high energy injury and requires aggressive operative management.

    Notes: Abstract Glass-ionomer cements (GIC) offer several advantages over the conventional acrylic-based bone cements. The formation of an adhesive bond with bone and metals, a low setting exotherm and no systemic or local toxicity are some of the advantages cited. This study examines the in vivo biological and biomechanical behavior of two polyalkenoate cements (LG26 and LG30) implanted for 6 wk into the submetaphyseal spongiosa of the rabbit femur. Cements were implanted as both set cement rods and unset cement dough. Implantation of set rods resulted in the formation of variably mineralized osteoid/woven bone at the bone–cement interface. Mechanical (push-out) testing revealed the strength of this bone–cement interface was of similar magnitude to control (PMMA-rod implanted) animals. The bone of LG cement-dough implanted animals exhibited demineralization of pre-existing bone local to the site of implantation, accumulation of aluminum both locally and at a distance from the site of implantation, and defective mineralization of newly formed osteoid. The histological picture following LG implantation was strikingly similar to human renal osteodystrophy, in which skeletal accumulation of aluminum is a noted feature. The development of a GIC with low/no aluminum release from the unset cement dough is a priority in the further development of these cements for possible orthopaedic applications. © 1998 Kluwer Academic Publishers
