Stephen M Quinnan
Ring fixation is a powerful tool in the treatment of bone defects. The ability to create high-quality, biologically normal new bone of even massive proportions using distraction osteogenesis is a major reason for its success. In addition, ring fixation provides the ability to limit the risk of deep infection, improves flexibility in limb length control and alignment, and increases soft tissue coverage options. The drawbacks of ring fixation include long frame times, pin problems, risk of joint contractures, and difficult usage in areas with a large soft tissue envelope such as the thigh...

The induced membrane technique for reconstruction of bone defects has proved its effectiveness and is now widely accepted. The 2 stages procedure, implying a cement spacer in the first stage and a huge bone graft in the second stage, responds to rigorous technical details involving each phase of the procedure. Prerequisites for the technique, cement spacer, bone fixation, time between the 2 stages, grafting, and postoperative course are reported and discussed.

The management of long bone defects continues to be associated with significant challenges for optimum and timely bone repair. When bone grafting is needed, essential parameters to be addressed include adequate volume, optimum density, and structural capacity as well as potent biological properties. Although the autologous iliac crest bone graft remains the gold standard, its reduced availability and donor site morbidity have made the clinicians to seek for other alternative options. Reamer irrigator aspirator graft with materials used as graft expanders along with inductive molecules and cellular augmentation constitute the current trend for optimum bone regeneration...

Paul Toogood, Theodore Miclau
Bone defects associated with open fractures require a careful approach and planning. At initial presentation, an emergent irrigation and debridement is required. Immediate definitive fixation is frequently safe, with the exception of those injuries that normally require staged management or very severe type IIIB and IIIC injuries. Traumatic wounds that can be approximated primarily should be closed at the time of initial presentation. Wounds that cannot be closed should have a negative pressure wound therapy dressing applied...

Emil H Schemitsch
Bone defects are common and are associated with a significant burden of disease. The treatment of these injuries remains controversial, particularly those defects which are critical sized. Despite the need for decision making to be evidence based, a lack of consensus around definitions of critical-sized defects still exists, particularly around those defects in the 1-3 cm range. There is a need to define "critical" in bone defect size because noncritical defects may heal without planned reconstruction and secondary surgery...

Reconstruction of segmental bone defects requires a large commitment both on the part of the patient and the physician. Investing in preoperative evaluation and optimization is the only logical way to pursue such an endeavor. Unfortunately, detailed studies regarding segmental bone defects and preoperative factors are relatively lacking owing to the relatively low incidence of the problem. Fortunately, other orthopaedic pathologies (arthritis, ligamentous injuries about the knee) have high prevalence and consistency, allowing detailed analysis of preoperative factors...

High-energy, open tibial shaft fractures may result in significant comminution, bone loss, and soft tissue injuries. Early, thorough debridement of all nonviable tissue is of critical importance in treating these fractures as an inadequate initial debridement increases the risk of infection and nonunion. Large iatrogenic bone and soft tissue defects can result from debridement and will require subsequent reconstruction by both orthopaedic and plastic surgeons. Although a variety of approaches exist to address these reconstructions, successful management of bone defects remains a considerable challenge...

PURPOSE: Clinical indications are expanding for the use of fasciocutaneous free flaps in lower extremity traumatic reconstruction. We assessed the impact of muscle versus fasciocutaneous free flap coverage on reconstructive and functional outcomes. METHODS: A multicenter retrospective review was conducted on all lower extremity traumatic free flaps performed at Duke University (1997-2013) and the University of Pennsylvania (2002-2013). Muscle and fasciocutaneous flaps were compared in two subgroups (acute trauma and chronic traumatic sequelae), according to limb salvage, return to ambulation, flap outcomes, and secondary flap procedures...

Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry...

Distraction osteogenesis has proven effective in the management of tibial bone loss from severe trauma and infection. Unfortunately, pain and scarring from wires and half pins dragging through the skin and the required prolonged time in the external fixator make treatment difficult. Cable bone transport has been shown to improve cosmesis and decrease pain during transport. However, the published methods have limitations in that they have poor control of transport segment alignment, do not allow for lengthening of the limb, and do not permit weight bearing during the treatment process...

BACKGROUND: In forensic sciences to determine one's sex is quite important during the identity defining stage. The reliability of sex determination depends on the completeness of the remains and the degree of sexual dimorphism inherent in the population. Computed Tomography is the imaging modality of choice for two- and three-dimensional documentation and analysis of many autopsy findings. OBJECTIVE: The aim of the present work was to assess the reliability of Three-dimensional Multislice Computed Tomography (3D MSCT) to determine sexual dimorphism from certain chest measurements; sternum and fourth rib using the 3D MSCT and to develop equations for sex determination from these bones among adult Egyptians sample...

Several methods are available to treat mandibular tumours. This case series demonstrates the feasibility of resection and immediate reconstruction with free rib graft in limited resource settings. Innovative technical modifications are described to handle the problem of reconstruction of the angle of the mandible and to provide increased bone bulk in the centre of the mandible. Early postoperative complications are few. Follow-up demonstrates good functional results.

PURPOSE: To determine the incidence of pseudarthrosis at the osteotomy site after three-column spinal osteotomies (3-COs) with posterior column reconstruction. METHODS: 82 consecutive adult 3-COs (66 patients) with a minimum of 2-year follow-up were retrospectively reviewed. All cases underwent posterior 3-COs with two-rod constructs. The inferior facets of the proximal level were reduced to the superior facets of the distal level. If that was not possible, a structural piece of bone graft either from the local resection or a local rib was slotted in the posterior column defect to re-establish continual structural posterior bone across the lateral margins of the resection...

Intercalary endoprosthetic reconstruction following diaphyseal resection of osseous tumors offers functional advantages through preservation of native joints adjacent to the resected defect. Use of such implants is restricted by the amount of bone available for stem fixation adjacent to the defect. This study aimed to determine whether short osseous segment fixation with acceptable outcomes and complication rate can be reliably achieved with a customized intercalary endoprosthesis following extended diaphysectomy...

Hip arthroplasty is a common procedure used for the treatment of fractures and degenerative processes affecting the hip. Proximal femoral replacement is an uncommon type of hip arthroplasty used for reconstruction after extensive bone loss. Proximal femoral replacement is used most commonly after the resection of the proximal femur for malignancies and for extensive bone loss encountered in revision hip arthroplasty and occasionally for extensive bone loss after fractures. The authors present a case of a female patient who sustained a prosthetic dislocation of her proximal femoral replacement during sexual intercourse...

REVIEW
Adil Naeem, Hugo Gemal, Duncan Reed
A fracture of the mandible is a common trauma presentation amongst young males and represents one of the most frequently encountered fractured bones within the viscerocranium. Historically, assault was the dominant contributing factor but now due to the increased number of vehicles used per capita, motor vehicle accidents are the primary cause. Mandibular fractures can be classified anatomically, by dentition, by muscle group and by severity. The fracture may also be closed, open, comminuted, displaced or pathological...
