The aim of this study was to investigate whether growth factors essential for fracture healing are released in the immediate aftermath following fracture and whether reaming of IM cavity causes increased liberation of these autocoids. Consecutive adult patients with femoral shaft fractures forming two groups (a group who received unreamed nail (n=10) and a second group who received reamed nail (n=10) were recruited for this study. Peripheral blood samples and samples from the femoral canal before and after reaming and before and after the solid nail insertion were collected. Serum was extracted and using Elisa colorimetric assays the concentration of Platelet Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), Insulin-like Growth Factor I (IGF-I) Transforming Growth Factor beta 1 (TGF-21) and BMP-2 levels was measured.Purpose
Methods
The timing of definitive fixation for major fractures in polytrauma patients is controversial. To clarify this aspect of trauma management, we randomised patients with blunt multiple injuries to either initial definitive stabilisation of the femur shaft with an intramedullary nail or an external fixator which was converted to an intramedullary nail at a secondary procedure and documented the post-operative clinical condition. Multiply injured patients with femoral shaft fractures were randomised to either initial (<24 hours) intramedullary femoral nailing or to initial external fixation and conversion to an intramedullary nail at a later phase. Inclusion criteria: New Injury Severity Score >16 points, or 3 fractures and Abbreviated Injury Scale score >2 points and another injury (Abbreviated Injury Scale score >2 points), and age 18 to 65 years. Exclusion criteria: unstable or patients in extremis. Patients were graded as stable or borderline (increased risk of systemic complications). OUTCOMES: Incidence of acute lung injuries.Purpose
Methods
We aimed to investigate the treatment and outcome of patients over 65 years of age with tibial Pilon fracture. Patients were treated by primary open reduction and internal fixation or external fixation (EF) as determined by local soft tissue conditions. Patient course, incidence of radiological osteoarthritis and functional outcome using the SF-36 questionnaire were recorded. All patients were evaluated serially until discharge from final follow-up. The mean follow-up time was 28 months (12-45). Statistical analysis was performed using Analyse-it(tm) software for Excel. In total 25 patients were studied. Two patients died before completion of treatment and were excluded from the final analysis. Therefore, 23 patients (10 male) were included with a mean age of 70.9 years (range 66-89) and a mean ISS of 10.25 (range 9-22). There were 4 grade IIIb open injuries. Three patients suffered superficial tibial wound infection. Two patients underwent early secondary amputation due to deep bone sepsis within 8 weeks of injury. One patient in the ORIF group underwent primary arthrodesis, which was subsequently revised due to non-union. 3 patients underwent secondary bone grafting to enhance healing, performed at 2, 6 and 9 weeks. 2 patients with metal work failure underwent subsequent revision of ORIF and progressed to union; the mean time to union was 33.8 weeks. At final follow-up 7 (28%) patients had radiological features of osteoarthritis but none had symptoms severe enough to warrant ankle arthrodesis. There were significant differences from the USA norm in physical function score, role physical score, and physical component score, (p< 0.01). In older patients local complications are relatively common and clinical vigilance must be maintained in order to allow appropriate intervention during their post-operative course. Despite the incidence of radiological post-traumatic arthrosis, none of the patients progressed to ankle fusion.Conclusion/Significance
