A systematic review of the literature was conducted to investigate data regarding femoral head fractures, particularly focusing on their management, complications and clinical results. Twenty-nine eligible articles, meeting prespecified inclusion criteria, reported on 453 femoral head fractures in 450 patients (mean age of 38.9 years with a mean follow-up of 55.6 months). 84.3% of patients had been victims of an automobile accident. The most widespread classification scheme used was that of Pipkin (65.4% of cases) whereas clinical results were evaluated mainly according to Thompson-Epstein criteria (63.3% of cases). ⋯ Wound infection was encountered with a rate of 3.2% of surgical cases and sciatic nerve palsy complicated 3.95% of fracture-dislocations. Major late complications included avascular necrosis (11.9%), post-traumatic arthritis (20%) and heterotopic ossification (16.8%). Neither the trochanteric-flip nor the anterior approach seems to put in more danger the femoral head blood supply compared to the posterior one, with the former giving promising long-term functional results and lower incidence of major complication rates.

Case Reports Multicenter Study
Application of bone morphogenetic proteins to femoral non-unions: a 4-year multicentre experience.
Fracture non-unions often complicate orthopaedic trauma. BMPs (bone morphogenetic proteins) are currently considered the most appealing osteoinductive agents. Applications of BMP-7 since January 2004 were prospectively recorded in a multicentre registry of aseptic femoral non-unions. ⋯ No adverse events were associated with BMP-7 application. Our case series supports the safety and efficacy of BMP-7 in femoral non-unions. Multicentre networks and systematic, long-term follow-up of patients may improve understanding of this promising osteoinductive bone substitute.

The purpose of this study was to determine whether three-dimensional reconstructed computed tomography (CT) images can improve intra-observer and inter-observer reliability for classification systems of tibial plateau fractures compared to plain radiographs and two-dimensional CT images. ⋯ Three-dimensional CT is a more reliable radiographic modality than 2D CT in evaluation of fracture patterns in tibial plateau fractures. This finding seems to show that more sophisticated imaging techniques can improve the reliability of fracture classification systems.

The recent development of new orthopaedic devices and advanced techniques for soft-tissue reconstruction have clearly improved the outcome in trauma and orthopaedic surgery. Nevertheless, large bone defects are still difficult to treat and require a careful analysis of the situation. Individual planning of the reconstructive strategy is desirable. ⋯ BMPs are often used in combination with autogenic, allogenic, xenogenic or synthetic grafting materials and even with mesenchymal stem cells. In addition, gene therapy approaches present an attractive option. Experimental studies and first clinical results are promising in the use of BMPs for treatment of critical-size defects; however, there is obvious need for further controlled studies to define strategies.

Current ATLS protocols dictate that spinal precautions should be in place when a casualty has sustained trauma from a significant mechanism of injury likely to damage the cervical spine. In hostile environments, the application of these precautions can place pre-hospital medical teams at considerable personal risk. It may also prevent or delay the identification of airway problems. In today's global threat from terrorism, this hostile environment is no longer restricted to conflict zones. The aim of this study was to ascertain the incidence of cervical spine injury following penetrating ballistic neck trauma in order to evaluate the need for pre-hospital cervical immobilisation in these casualties. ⋯ Penetrating ballistic trauma to the neck is associated with a high mortality rate. Our data suggests that it is very unlikely that penetrating ballistic trauma to the neck will result in an unstable cervical spine in survivors. In a hazardous environment (e.g. shooting incidents or terrorist bombings), the risk/benefit ratio of mandatory spinal immobilisation is unfavourable and may place medical teams at prolonged risk. In addition cervical collars may hide potential life-threatening conditions.
