A healthy respect for the tenuous soft tissue envelope, compromised vascularity, and challenging mechanical environment is advisable. Achieving osseous union and improved functionality requires an individualized plan of care based on the personality of the nonunion and host. Attention must be focused on providing mechanical stability at the site of nonunion and providing biologic supplementation.

Preoperative planning and the potential advantages and disadvantages of newer fixed-angled plates versus established implants are discussed. With proper planning, surgical execution with proved techniques, augmented by the addition of newer graft harvesting techniques, anatomic restoration, and bone reconstitution with healing, has invariably been the result.

The most common indication for RIA is harvesting of autololgous bone graft from the femur for nonstructural bone graft. The second most common indication is for irrigation and debridement of intramedullary osteomyelitis. The final indication for RIA is for acute nailing of femoral shaft fractures in patients with multiple long bone fractures with or without pulmonary injury. If one pays careful attention to the details of the technique, RIA is a safe and effective method of harvesting autologous bone graft with minimal morbidity. Autologous bone graft harvested with RIA is our graft of choice for nearly all of our bone grafting cases.

We also quantify growth factor concentrations in the collections from the TCP filter. A second filter attached in series with the standard RIA filtration system yields TCP with substantial concentrations of bioactive proteins that are equal to those seen in the bone graft that is harvested in the first filter.

The graft expansion with growth factors as the bone morphogenetic proteins (BMPs) offers the possibility to reduce the number of operative procedures, complications, length of hospital stay, and time to union. In this article, we consider the potential clinical scenarios for graft expansion with BMPs.

Anterior iliac crest graft is the most commonly used site; however, the posterior iliac crest and intramedullary canal provide greater quantities of bone. The anterior and posterior iliac crests also have some donor site complications such as nerve injury and persistent pain. The intramedullary canal, when compared with anterior and posterior iliac crest, offers the largest quantity of bone graft with the least amount of patient donor site morbidity. The intramedullary canal also appears to be a bone graft source that can be reharvested, unlike the anterior and posterior iliac crest donor sites.

The reamer-irrigator-aspirator (RIA) technique allows access to a large volume of cancellous bone graft containing growth factors with potency equal to or greater than autograft material from the iliac crest. The purpose of this study was to evaluate the effectiveness of RIA-harvested autogenous bone graft for treating large segmental defects of long bones.

The biologic potential of intramedullary reaming material has been studied both in vitro and in vivo. The material provides osteogenic, osteoinductive, and osteoconductive properties that are comparable to the material harvested from the iliac crest. In addition to the ability to obtain a large volume of bone, the graft harvested by the Reamer-Irrigator-Aspirator has been shown to be rich in growth factors, including BMP-2, TGF-β1, IGF-I, FGFa, and PDGFbb.

Clinically relevant animal models have demonstrated that standardized particulate bone constructs can be used to repair large bone defects using the procedure and that the osteogenic ability of these constructs partially approaches that of bone autografts.

Although many treatment approaches exist, they all have limitations. Recently, bioresorbable polylactide membranes have become commercially available. These membranes, when applied to bone defects, enhance bone healing by direct osteoconduction, exclusion of nonosseous tissues, and enhancing the osteogenic environment for autologous grafts. When combined with appropriate internal fixation and autologous bone graft, bioresorbable polylactide membranes allow for single-step reconstruction of large bone defects.

The main properties of the membrane are to prevent the resorption of the graft and to secrete growth factors. The induced membrane appears as a biological chamber, which allows the conception of numerous experimental models of bone reconstruction. This concept could probably be extended to other tissue repair.

The surgeon must choose adequate fixation for stability and to promote healing by not making the construct too stiff. If a bone graft substitute is necessary, the surgeon must choose the type of bone graft substitute depending on patient factors and surgeon factors involving the treatment of the fracture.

Current non-invasive therapeutic alternatives are anti-inflammatory in nature, and outcomes are unpredictable. The benefit of invasive alternatives resides in the induction of the healing response. A new technology that uses non-invasive monopolar capacitive coupled radiofrequency has demonstrated the ability to raise temperatures in tendons and ligaments above 50°C, the threshold for collagen modulation, tissue shrinkage and recruitment of macrophages, fibroblasts, and heat shock protein factors, without damaging the overlying structures, resulting in activation of the wound healing response.

Despite a long learning curve and technical demands of the procedure, thoracoscopy has several advantages, including better cosmesis, adequate exposure to all levels of the thoracic spine from T2 to L 1, better illumination and magnification at the site of surgery, less damage to the tissue adjacent to the surgical field, less morbidity when compared with standard thoracotomy in terms of respiratory problems, pain, blood loss, muscle and chest wall damages, consequent shorter recovery time, less postoperative pulmonary function impairment, and shorter hospitalization. Good results at short- and medium-term follow-up need to be confirmed at long-term follow-up.

The use of PVP is a minimally invasive option in the treatment of osteoporotic or metastatic vertebral collapses. Our personal experience, using a CT-guided technique, confirms the efficacy and safety of PVP with a lower risk for complications compared with conventional fluoroscopic approaches because of a precise placement of the instruments in the vertebral body and an early detection of small cement leakages.

It is technically demanding. Although some would consider that arthroscopy is the ultimate minimally invasive procedure, over the course of the last few years many techniques and philosophies of treatment have been introduced and have since evolved. Now such techniques are used to manage fractures, nonunions, malunions, bone infections, arthritis, and deformities. These techniques have the theoretic advantage of decreasing recovery and rehabilitation times, because surgical exposure and deep tissue dissection are smaller and gentler to the soft tissues.

The use of a gait, or biomechanical, analysis provides objective evidence of the efficiency of the treatments or the effectiveness of hip replacement approaches. Based on our biomechanical analysis, patients who have undergone total hip arthroplasty use a stair ascent and descent strategy allowing them to significantly reduce loading at the prosthetic hip joint. Since hip joint reaction forces are highly dependent on muscle activation, the THA group have adopted a neuromuscular control strategy that is enabling them to reduce loading on the prosthetic hip joint. It could also be a joint loading pattern that stems from a muscular defi...

Review of our human data suggests that the MRI contrast dye is retained for longer periods of time, suggesting decreased perfusion out of regions of osteoarthritis and avascular necrosis. Use of such a noninvasive measure of assessing bone perfusion could be useful in the diagnosis, prevention, and treatment of not only osteoarthritis and avascular necrosis but also other entities that affect the musculoskeletal system.

The parenteral administration of the vasoactive drug iloprost constitutes a new approach to the treatment of painful bone marrow edema syndrome of the hip of pregnant women. Six postpartal women (8 hips) with bone marrow edema syndrome of the femoral head were treated with iloprost followed by 3 weeks of partial weight-bearing. Relief from pain, restoration of functional capacity, and normalization of the MRI signal pattern were rapidly achieved, thus avoiding the need for surgical intervention. As the substance is contraindicated in pregnancy, therapy may begin only some days aft...

Limited data suggest that statins modulate cholesterol metabolism and may protect against osteonecrosis. The authors analyzed their prospective renal transplant database to determine if statin usage reduces the incidence of corticosteroid-related osteonecrosis and identified 2,881 renal transplantation patients who met the entry criteria. Among 338 patients on statins, 15 (4.4%) developed osteonecrosis, versus 180 of 2,543 (7%) patients who were not on statins. Osteonecrosis-free survival was similar in patients with and without statin exposure.

Their use in treating osteonecrosis of the femoral head has been studied and theoretically holds promise. There are complications associated with these medications, however, including the development of osteonecrosis in the jaw.

For the treatment of osteonecrosis, most studies have focused on pain relief, surgery, or the need for surgery, disease progression (advancing stage), and change in lesion size. Quantification of imaging techniques continue to gain in sophistication but have not yet been validated for use in clinical trials. Despite recent interest in using biomarkers or genetic markers in the diagnosis and analysis of disease progression, more research is needed to determine the sensitivity and specificity of these techniques with respect to osteonecrosis.
