Abstract
Sacral insufficiency fractures are traditionally treated with bed rest and analgesia. The importance of early rehabilitation is generally appreciated; but pain frequently delays this, resulting in prolonged hospital stay and the risk of complications related to immobility. We describe three women with sacral insufficiency fractures who were treated with percutaneous sacroiliac screws and followed up for a mean of 18 months (12 to 24). They had immediate pain relief, uncomplicated rehabilitation and uneventful healing.

Abstract
The present review evaluates the existing scientific proofs of this supplementary role of the BMPs and summarises its clinical implications. Bone regeneration is a process consisting of bone formation and bone resorption, two different but closely coupling pathways, which in most circumstances proceed simultaneously. Plenty of evidence has also characterised the bone morphogenetic proteins (BMPs) as inducing factors of bone formation. However, there is also evidence that these multifunctioning proteins affect bone resorption and the osteoclast homeostasis utilising various pathways. The present review evaluates the existing scientific evidence of this supplementary role of the BMPs, and summarises its clinical implications.

Abstract
Technological advances and shorter rescue times have allowed early and effective resuscitation after trauma and brought attention to the host response to injury. Trauma patients are at risk of progressive organ dysfunction from what appears to be an uncontrolled immune response. The availability of improved techniques of molecular diagnosis has allowed investigation of the role of genetic variations in the inflammatory response to post-traumatic complications and particularly to sepsis. This review examines the current evidence for the genetic predisposition to adverse outcome after trauma. While there is evidence supporting the involvement of different polymorphic variants of genes in determining the post-traumatic course and the development of complications, larger-scale studies are needed to improve the understanding of how genetic variability influences the responses to post-traumatic complications and pharmacotherapy.

Abstract
Posterior dislocation or fracture-dislocation of the shoulder is a rare entity, and is often missed in the Emergency Department. The causes include a tonic-clonic seizure, electrocution, and major trauma. The clinical presentations are often misleading and thus the correct diagnosis may be delayed. Proper imaging of the shoulder in suspected cases is important in making the correct diagnosis. We report a rare case of bilateral posterior fracture-dislocation of the shoulders, which presented in the Emergency Department with clinical features suggestive of a dissecting aneurysm of the thoracic aorta. A review of the relevant literature is also presented.

Abstract
A protocol of early intervention (flexible intramedullary nails, early hip spica, and external fixation) was started in 1999 and during a 3-year period there were 25 children who sustained a femoral shaft fracture (early intervention group). These were prospectively reviewed with a minimum follow up of 24 months (Range 24-35 months). A historical control group of 41 children was used. These children were injured between February 1996 and February 1999 and were retrospectively reviewed. They had traditional in patient treatments with either Gallows or Thomas splint traction (traditional treatment group). Over the 6-year period from 1996 to 2002 there were a total of 66 femoral shaft fractures in the study that presented to our hospital. The mean length of hospital stay was 29 nights in the traditional group and 10 nights in the early intervention group. This difference is significant (p<0.001). The malunion rate was slightly higher in the early active group at radiological union but most of these remodelled over the 2 years of follow up. The protocol of early intervention used in our institution, of flexible nails, early hip spica or external fixation depended on the age of the child, and has resulted in a shorter hospital stay for the children. This has benefits for the child, the family and the hospital.

Abstract
Open fracture management represents an orthopaedic emergency. Early aggressive management of these debilitating injuries within the first 6h has been encouraged in order to minimise the risk of infection and long term sequelae. Debridement and wash-out of the wound, followed by stabilisation of the bony elements and closure of the soft-tissue envelope are all considered essential. However, the available scientific evidence supporting the timing of this multistage approach of open fracture management, and the "Six-hour rule" itself, are unclear. This review article analyses the available evidence regarding the impact of the timing of wound debridement and closure of open fractures of the lower extremity.

Abstract
With the development of systems of trauma care the management of pelvic disruption has evolved and has become increasingly refined. The goal is to achieve an anatomical reduction and stable fixation of the fracture. This requires adequate visualisation for reduction of the fracture and the placement of fixation. Despite the advances in surgical approach and technique, the functional outcomes do not always produce the desired result. New methods of percutaneous treatment in conjunction with innovative computer-based imaging have evolved in an attempt to overcome the existing difficulties. This paper presents an overview of the technical aspects of percutaneous surgery of the pelvis and acetabulum.

Abstract
There is a potential for the use of pharmacological agents to enhance the quality of bone around a total hip or knee prosthesis, reducing the risk of implant failure or periprosthetic fracture. Bisphosphonates are currently used for the management of postmenopausal osteoporosis and recent investigations also suggest a potential role for the management of postoperative periprosthetic bone loss. Current evidence suggests that the short-term gains may not be sustained in the long term. Teriparatide and parathyroid hormone 1-84 have been licensed to treat postmenopausal osteoporosis and may also be investigated for the potential to enhance periprosthetic bone mass. In addition, other agents such as calcitonin and strontium ranelate, non-anabolic agents such as doxycycline, and recombinant OPG adeno-associated virus (rAAV) gene therapy, may in the future provide solutions for enhancing periprosthetic bone mass.

Abstract
Modern principles for the treatment of open fractures include stabilisation of the bone and management of the soft tissues. Wound debridement and irrigation is thought to be the mainstay in reducing the incidence of infection. Although numerous studies on animals and humans have focused on the type of irrigation performed, little is known of the factors which influence irrigation. This paper evaluates the evidence, particularly with regard to additives and the mode of delivery of irrigation fluid. Normal saline should be used and although many antiseptics and antibiotics have been employed, no consensus has been reached as to the ideal additive. Despite the advocates of high-pressure methods highlighting the improved dilutional ability of such techniques, the results are inconclusive and these irrigation systems are not without complications. New systems for debridement are currently being investigated, and an ideal method has yet to be determined.

Abstract
Our aim was to evaluate the efficacy of a two-level reconstruction technique using subchondral miniscrews for the stabilisation of comminuted posterior-wall marginal acetabular fragments before applying lag screws and a buttress plate to the main overlying posterior fragment. Between 1995 and 2003, 29 consecutive patients with acute comminuted displaced posterior-wall fractures of the acetabulum were treated operatively using this technique. The quality of reduction measured from three standard plain radiographs was graded as anatomical in all 29 hips. The clinical outcome at a mean follow-up of 35 months (24 to 90) was considered to be excellent in five patients (17%), very good in 16 (55%), good in six (21%) and poor in two (7%). The use of the two-level reconstruction technique appears to provide stable fixation and is associated with favourable results in terms of the incidence of post-traumatic osteoarthritis and the clinical outcome. However, poor results may occur in patients over the age of 55 years.

Abstract
We report the management of an adult patient with septic sacroiliitis. This is an uncommon condition. Debridement, decompression and spontaneous fusion are the treatment of choice when symptoms do not resolve with routine initial intravenous antibiotic therapy. A percutaneous technique is described, using the principles of sacroiliac screw insertion commonly used for pelvic reconstruction surgery. After successful evacuation of the infected joint, fusion was observed in our patient.

Abstract
BACKGROUND Sacral insufficiency fractures (SIFs) are often overlooked in elderly patients presenting with low back and pelvic pain following no or minimal trauma. OBJECTIVE The aim of this review is to raise awareness and outline the clinical presentation, methods of diagnosis and treatment of SIFs. DISCUSSION Insufficiency fractures represent a special category of stress fractures that occur in bones with reduced mineral content and elastic resistance. SIFs, a well-defined subgroup of the latter group, are not uncommon, but lack of clinical suspicion results in many being undiagnosed. SIFs are set to become an important clinical entity of both social and economic significance as the Western population ages. Subtle clinical presentations and signs coupled with radiographic findings that can mimic other unrelated or overlapping conditions, such as sacroiliac joint infection, spinal stenosis and metastatic bone disease, often make SIF diagnosis a challenge. The aim of this review is to increase awareness among clinicians, highlighting SIFs as an important differential diagnosis to be considered when patients present with low back and pelvic pain and subsequently allow prompt management. The paper provides an overview of epidemiology, anatomical considerations, relevant pathophysiology and risk factors, presenting symptoms and signs, investigations and imaging techniques, differential diagnoses and current treatment methods available for the management of SIFs.

Abstract
In infections following orthopaedic surgery, isolated staphylococci are reported to be methicillin resistant (MRSA) in up to 50% of cases. Linezolid, the first in a new class of antibiotics, has excellent efficacy against gram positive organisms that are resistant to other therapies and is 100% orally bioavailable. We report early results of its use for the treatment of resistant infections in orthopaedic practice. Infections were characterised according to the UK Nosocomial Infections National Surveillance Service classification of surgical infections as superficial, deep or organ/space. Osteomyelitis, joint sepsis and deep infection involving orthopaedic implants were included into the final category. Outcome was recorded as clinical, microbiological and blood parameter cure or fail. Over the 12-month study period, 54 patients received linezolid therapy, 41% of these had significant co-morbidity that might affect their ability to fight infection. Sixty-seven percent of infections were in association with implanted metal work. The majority of patients were treated with vancomycin for a short period before linezolid was used as oral 'switch' therapy for longer-term administration, allowing early discharge in all cases. MRSA was isolated in 87% of the patients treated. The mean length of linezolid therapy was 39 days (2-151). Clinical success was achieved in 90% of patients overall. Though there were no life-threatening complications, adverse event rates were significantly higher than those recorded in the literature, with 19% of patients needing to cease therapy. Linezolid offers an alternative to traditional treatments for resistant infections and can facilitate early discharge. Patients need to be monitored closely, particularly where long-term therapy is planned.

Abstract
The effect of head injury on systemic physiology, including bone healing is still a topic of vivid discussion. Whether the observed changes genuinely represent accelerated fracture healing or are a form of local heterotopic ossification remains unclear. We aimed to investigate whether in patients with long bone fractures the presence of head injury is associated with accelerated bone healing and excessive callus formation. In total 67 patients were studied 17 with head injury and 50 without head injury (25 treated with reamed and the other 25 with the unreamed nailing technique). Both groups were comparable in terms of age, sex, ISS. All underwent stabilisation of their femoral fracture with intramedullary nailing. The quantification of fracture healing response was estimated by taking the radiological ratio of the largest diameter of callus formed into two planes and the adjacent normal diameter of femoral canal. The minimum follow up of the patients was 12 months. In patients with head injury, the mean time to fracture union was significantly shorter than either the reamed or unreamed group (10.5 weeks compared with 20.5 and 26.9 weeks, p<0.001). The difference between the mean callus to diaphyseal ratio was statistically significant for both the AP and Lateral projections (AP: mean difference 0.462, 95% CI 0.312 to 0.602, p<0.0001, LAT: mean difference 0.289, 95% CI 0.142 to 0.436, p<0.001) with the head injured patients having more florid callus compared to the control group.

Abstract
Early, primary amputations are still necessary for certain patients sustaining high impact lower limb trauma. For cases with extensive proximal tibial bone loss a turn-up bone flap technique has been described to achieve a below-knee stump suitable for a prosthesis. However, in certain circumstances, for example if posterior soft tissues are injured, this type of reconstruction is not possible. This case report demonstrates that converting a severe open proximal tibial fracture to a successful below-knee amputation is also possible with acute limb shortening, flap cover and planned subsequent trans-tibial amputation.

Abstract
The management of radial nerve palsy associated with fractures of the shaft of the humerus has been disputed for several decades. This study has systematically reviewed the published evidence and developed an algorithm to guide management. We searched web-based databases for studies published in the past 40 years and identified further pages through manual searches of the bibliography in papers identified electronically. Of 391 papers identified initially, encompassing a total of 1045 patients with radial nerve palsy, 35 papers met all our criteria for eligibility. Meticulous extraction of the data was carried out according to a preset protocol. The overall prevalence of radial nerve palsy after fracture of the shaft of the humerus in 21 papers was 11.8% (532 palsies in 4517 fractures). Fractures of the middle and middle-distal parts of the shaft had a significantly higher association with radial nerve palsy than those in other parts. Transverse and spiral fractures were more likely to be associated with radial nerve palsy than oblique and comminuted patterns of fracture (p < 0.001). The overall rate of recovery was 88.1% (921 of 1045), with spontaneous recovery reaching 70.7% (411 of 581) in patients treated conservatively. There was no significant difference in the final results when comparing groups which were initially managed expectantly with those explored early, suggesting that the initial expectant treatment did not affect the extent of nerve recovery adversely and would avoid many unnecessary operations. A treatment algorithm for the management of radial nerve palsy associated with fracture of the shaft of the humerus is recommended by the authors.

Abstract
A tricortical bone graft harvested from the ilium was used to reconstruct a severely comminuted open intra-articular distal humerus fracture in an adult patient. The patient demonstrated a satisfactory functional and radiologic outcome despite loss of the lateral trochlear lip. When the lateral portion of the fractured trochlea cannot be repaired, excision of the fragments and insertion of an autogenous corticocancellous bone graft from the iliac crest can restore satisfactory function, even in the setting of an open fracture provided there is limited contamination and tissue devitalization. Radiocapitellar contact may be essential to good elbow function in this situation, because the corticocancellous bone graft does not restore the important lateral lip of the trochlea.

Abstract
The purpose of this study was to evaluate the efficacy and safety of recombinant bone morphogenetic protein 7 (rhBMP-7 or OP-1) as a bone-stimulating agent in the treatment of persistent fracture non-unions. Twenty-five consecutive patients [19 males, mean age 39.4 years (range: 18-79)] with 26 fracture non-unions were treated with rhBMP-7. There were 10 tibial non-unions, eight femoral, three humeral, three ulnar, one patellar, and one clavicular non-union. The mean follow-up was 15.3 months. The mean number of operations performed prior to rhBMP-7 application was 3.2, with autologous bone graft and bone marrow injection being used in 10 cases (38.5%). Both clinical and radiological union occurred in 24 (92.3%) cases, within a mean time of 4.2 months and 5.6 months, respectively. Of the remaining two cases, one patient ultimately underwent a below knee amputation, secondary to recurrence of deep sepsis. The other patient with recalcitrant ulnar non-union although the radiological union was incomplete, declined further intervention, as he was asymptomatic. No complications or adverse effects from the use of rhBMP-7 were encountered. This study supports the view that the application of rhBMP-7 as a bone-stimulating agent is safe and a power adjunct to be considered in the surgeon's armamentarium for the treatment of these challenging clinical conditions.
