The results of operative treatment of acetabular fractures as well as its role in the occurrence of post-traumatic osteoarthritis (OA) are presented. From 1990 to 2000, 50 patients (32 male and 18 female), aging from 18 to 71 years (mean: 37.8 years) underwent an open reduction and internal fixation of their displaced acetabular fracture. They were reviewed at a mean of 5.8 years (2-10 years). ⋯ Early post-operative complications included 2 peroneal nerve palsies and 3 wound infections and late complications included 1 patient with avascular necrosis of the femoral head (ANFH), 5 patients with grade III and IV heterotopic ossification according to Brooker classification and 12 patients with post-traumatic osteoarthritis of the hip joint. Although the rates of early and late complications were relatively common, the functional outcome was satisfactory in most of the cases and comparable with other larger series. We concluded that operative treatment of most of the displaced acetabular fractures--except of isolated anterior column or/and anterior wall - could be attempted via a single posterior approach, leading to good to excellent results in the majority of the cases.

With the introduction of Locking Compression Plates (LCP), Minimally Invasive Plate Osteosynthesis (MIPO) has become widely used. The plates act as internal fixators in a bridging manner, thus resulting in secondary bone healing. We retrospectively evaluated the healing pattern and the clinical evolution of diaphyseal and distal tibial shaft fractures over two and a half years in 32 patients (6 females, 26 males). ⋯ Plate bending was observed in one patient and called for re-operation at 5 months. Two patients required re-operation at 13 months secondary to pseudoarthrosis. Though MIPO seems more advantageous for soft tissue and bone biology, prolonged healing was observed in simple fracture patterns when a bridging plate technique was used.

Studies of the consequences of major trauma have traditionally focused on mortality rates. The aims of this study were, firstly, to investigate the long-term functional health status in a large, unselected group of severely injured patients and to compare this with normative data, and secondly, to explore relations between functional health status and personal and injury characteristics. ⋯ Subjects were 249 men and 86 women, mean age 37.7 years, mean ISS was 24.9 (S.D.=10.6). Almost, three quarters were traffic victims. Mean hospital stay was 25 days (S.D.=23.4). Discharge destination was home in 70% of all subjects. At follow-up, the mean overall SIP score was 9.3 (S.D.=10.1), which means mild to moderate disability. The mean score on the physical function dimension was 7.2 (S.D.=9.8) and that on psychosocial function was 8.7 (S.D.=12.0). Most problems were experienced in the categories of Work, Ambulation, Home Management, Recreation and Pastimes, and Alertness Behaviour. Scores of younger subjects deviated more strongly from the norm scores than those of elderly patients. Type of injury, especially lesions of traumatic brain and spinal cord and extremity injuries, was a predictor of both psychosocial and physical functioning after more than 1 year. The most important predictors, however, were age and co-morbidity.

To investigate in vitro the mechanical stability of a locking compression plate (LCP) construct in a simulated diaphyseal fracture of the humerus at increasing distances between the plate and bone. ⋯ At a distance 5 mm we observe an inferior performance in the mechanical properties of the LCP construct with decrease in axial stiffness and torsional rigidity. If it is desirable for an LCP to be used the distance between plate and bone should be

Post-injury abdominal compartment syndrome (ACS) is an increasingly recognised phenomenon in critical care. During the last decade, ACS had also been characterised in patients without abdominal injuries, referred to as secondary ACS. ⋯ Regardless of the cause of the syndrome and the nature of any extra-abdominal injuries, secondary ACS is invariably associated with massive fluid resuscitation. With a reliable, predictive model and new monitoring techniques, trauma clinicians should be able to identify the high-risk patient and attenuate the impact of this syndrome.
