[Metaphyseal defect substitute: hydroxylapatite ceramic. Results of a 3 to 4 year follow up].

45 trauma patients with fracture-related metaphyseal bone defects filled with hydroxyapatite ceramic (Endobon) were followed for three to four years after surgery. Osseointegration of Endobon could be confirmed histologically in all biopsates, which could be obtained during scheduled reintervention for hardware removal. The objective of clinical and radiological follow-up was to evaluate the extent of ceramic remodeling as well as long-term implant outcome. Thirteen patients undergoing surgery in 1992 or 1993 were available for follow-up. None of these patients showed radiologic evidence of loss of bony reconstruction or HAC sintering, nor was there evidence of HAC resorption or fragmentation. Our results--with respect to the examined few patients--suggest that Endobon is useful for filling bony defects in carefully selected trauma patients if certain surgical technique prerequisites are met. Like cancellous autografts special alloplasts appear to go some way toward solving problems of defect filling encountered in clinical practice.

External fixation in forearm shaft fractures.

External fixation for uncomplicated forearm fractures is rarely performed. The situation is different in a multiply injured patient or in a fracture with considerable soft tissue damage. In these cases the external fixator confers quick and efficient stabilisation which meets the requirements of adequate nursing and aids recovery of the general and local condition. Later change to an appropriate internal fixation procedure for definitive fracture treatment is recommended.

[Craniocerebral trauma in fall from bicycles--what is the effect of a protective helmet?].

A prospective study was performed to analyze the particular injuries of 76 cyclists who required in-patient treatment in our department in 1994. There were 50 male and 26 female cyclists, with a median age of 33 years (range: 4-87 years). The most frequent diagnosis, in 50% (n = 38), was head injury. The series included 63 cyclist (83%) who had not been wearing helmets, and 33 of these sustained a head injury; in the helmet group head injury was found in only 38% (5 out of 13). It is remarkable that more serious head injuries did not occur in the helmet group. In 24 of these 33 head-injured patients (73%) without helmets additional intra- and extracranial diagnoses were made: pathologic EEG in 18 patients (55%), skull fracture in 13 patients (39%), intracerebral haemorrhagic contusion in 4 patients (12%) and an increase in intracerebral pressure (edema) in 3 patients (9%). In contrast to these findings, only 2 of the 5 head-injured patients (40%) in the helmet group showed slight changes in the EEG. In our opinion the bicycle helmet can reduce the incidence and the grade severity of head injuries significantly, particularly as we had 2 deaths in the non-helmet group and none in the helmet group. The use of a bicycle helmet is therefore strongly advocated.
