Abstract
INTRODUCTION The reference surgical treatment for unstable posterior pelvic fracture is percutaneous iliosacral screw fixation, isolated or in association with other techniques. As there is a risk of passage outside the bone when performing screw fixation under fluoroscopy, new image-guidance techniques have been developed: fluoronavigation, peroperative 3D navigation, CT-linked navigation, etc. Since September 2011, our department has performed iliosacral screw fixation under CT control linked to navigation so as to optimize screw positioning. This innovative technology has been used in neurosurgery in our center since 2007, for disc implants, spinal fracture, vertebral arthrodesis and intracerebral localization. MATERIAL AND METHODS Six patients were treated by iliosacral screw fixation for posterior pelvic ring fracture lesion. The O-ARM (Medtronic(®)) computer-assisted surgical navigation system was used, combining surgical navigation and peroperative 3D imaging. This kind of osteosynthesis is suitable for non-displaced or prereduced fracture. A radiation dose report is drawn up at end of surgery. DISCUSSION Postoperative course does not differ from other percutaneous osteosynthesis techniques, combing the advantages of a percutaneous approach (reduced infection and blood-loss rates, etc.) while optimizing iliosacral screw positioning. To date, no radiation overexposure has been found. CONCLUSION The precision and safety of iliosacral screw fixation are now unequalled, meeting the basic computer-assisted surgery principles of reduced morbidity without overexposure to ionizing radiation. Indications for computer-assisted surgery should therefore be extended to iliosacral pathologies (arthritic, tumoral and inflammatory), non-displaced acetabular fracture, etc.

Abstract
BACKGROUND In an orthotopic rat osteosarcoma model, histological and molecular findings were compared with the results of non-invasive imaging methods to assess disease progression at the primary site, the pattern of metastatic dissemination and the chemoresistance phenotype. MATERIALS AND METHODS Primary tumor engraftment, vascularization, growth and metastatic spread were evaluated using 18FDG tomoscintigraphy. Bone neoformation in the primary tumor and metastasis was determined using 18FNa confirmed by classical histological studies. Chemoresistance phenotype was assessed by analysis of MDR1 and MRP1 genes expression compared to 99mTc MIBI imaging. RESULTS 99mTc MIBI imaging correlated with the overexpression of the MDR1 and MRP1 genes. 18FDG, 18FNa and 99mTc tomoscintigraphies revealed that the pattern of vascularization, bone neoformation and hematogeneous metastatic dissemination in our animal model mimics its human counterpart. CONCLUSION Multimodality, non-invasive imaging is a valid surrogate marker of histological and molecular characteristics in an orthotopic osteosarcoma model in immunocompetent rats; it allows extensive in vivo follow-up of osteosarcoma, including longitudinal analysis of chemoresistance.

Abstract
Excision is not a suitable treatment for all comminuted fractures of the radial head. In elbows where instability can be predicted, a replacement arthroplasty of the radial head is more effective. The aim of this paper was to present the medium-term results of the Judet floating radial head prosthesis. This operation was performed on 14 patients between 1992 and 2003, of whom 12 were reviewed at a mean follow-up of five years and three months (1 to 12 years). The outcome was assessed using the Mayo elbow performance score and a modified Disability of Arm Shoulder Hand (DASH) questionnaire. There were six excellent results, four good, one fair and one poor, as graded by the Mayo score. The mean DASH score was 23.9/100 (0 to 65.8/100). The only significant complication occurred in one patient who developed a severe complex regional pain syndrome. There were no patients with secondary instability of the elbow, implant loosening, cubitus valgus, osteoporosis of the capitellum, or pain in the forearm and wrist. Our experience, combined with that of other authors using this device, has encouraged us to continue using the Judet prosthesis in comminuted fractures of the elbow where instability is a potential problem.

Abstract
Traumatic lesions of the colon associated with fracture of the acetabulum occurs in less than 2% of the cases. Direct perforation of the colon by a bony spike, which occurred in our patient, is even more exceptional. We were unable to find any other case reported in the literature. This case illustrates the importance of looking for intestinal lesions in all patients with pelvic injury presenting an unexplained infectious syndrome. Imaging provides clear evidence for avoiding late diagnosis and life-threatening situations.

Abstract
We describe a model which can be used for in vitro biocompatibility assays of biomaterials. We studied the in vitro response of human osteoarthritis or rheumatoid arthritis fibroblast-like synoviocytes to Al2O3 or ZrO2 particles by analyzing the production of interleukin-1 (IL-1) and interleukin-6 (IL-6) and the metabolism of arachidonic acid via lipoxygenase and cyclo-oxygenase pathways. Our results show that, in these cells and under our experimental conditions, Al2O3 and ZrO2 did not significantly modify the synthesis of IL-1 and IL-6 or the metabolism of arachidonic acid.

Abstract
PURPOSE OF THE STUDY We studied the efficacy of papaine for treatment of herniated discs at a mean 10-year follow-up and compared results with other series and other treatments. MATERIAL AND METHODS From an initial group of 160 patients, 96 patients, 53 men and 43 women, mean age 39 years, were selected for evaluation. These patients had 46 L4L5 herniations and 50 L5S1 herniations. All 96 patients were operated in the same department and received the same dose of papaine under the same anesthesia conditions. All patients were followed regularly to 3 months postoperatively then were reviewed 3 to 17 years after surgery. Inquiries were made about return to work, pain, and activity. Physical examination and x-rays were obtained for all patients. RESULTS There were no neurological complications in our series. Seventeen patients required a second procedure for sciatic pain. Most of the patients continued their normal occupational and social activities after papaine treatment, but many of them had chronic lumbar pain. DISCUSSION Our results were comparable with series reporting a similar long follow-up. Surgery is more efficient than papaine but long-term results are equivalent. CONCLUSION Chemopapaine treatment provided good long-term results in our patients, similar to surgery. Chemonucleolysis may be employed as first line treatment for young patients with non-excluded disc herniation with sciatic pain.

Abstract
PURPOSE OF THE STUDY The aim of this study was to evaluate the long-term effect of tibiotalar arthrodesis on function, clinical and radiological tolerance, and subtalar joints. MATERIAL AND METHODS We reviewed 37 cases of tibiotalar arthrodesis in 27 young patients who were generally manual workers. Their mean age at surgery was 46 years and mean follow-up at review was 12.8 years (range 5-26 years). Functional outcome was assessed with the Duquennoy scale. We reviewed the anterioposterior and lateral weight-bearing views as well as the lateral view in dorsal and forced plantar flexion. RESULTS Mean functional outcome was good and very good in 66% of the cases, fair in 30% and poor in one case. Total pain relief had been achieved in 45% of the cases with a mean walking distance of 1500 m without crutches. Residual mobility at last follow-up was 13 degrees for the mediotarsal joint. This mobility allowed the arthrodesed foot to adapt to gait. Radiologically, fusion had been achieved in 83% of the cases within 3 months. The overall functional score fell off proportionally with the degree of arthrodesis valgus starting at 5 degrees. Likewise pes equinus > 10 degrees led to pain and reduced motion. The subtalar joints were affected in all cases, leading to poor adaptation of the foot on uneven ground. Grade 1 osteoarthritis affected the mediotarsal joint and was more marked in case of equine fixation. DISCUSSION Our results are similar to those reported in the literature. We had 4 cases of nonunion in patients with risk factors previously discussed in the literature. CONCLUSION Arthrodesis remains a useful method for treating talocrural osteoarthritis, providing good long-term results. The position of the fixation should be 90 degrees in the sagittal plane and 0 degrees to 5 degrees valgus in the frontal plane.

Abstract
We report a case of an aneurysmal cyst localized in the patella of a 37-year-old man. The lesion was secondary to a chondroblastoma at six years follow-up after initial curettage and bone graft. It were no recurrence. Treatment of aneurysmal cysts depends on the degree of articular involvement. We made a detailed study of 11 cases of this rare localization of aneurysmal cysts reported in the literature.

Abstract
We investigated the effects of the biomaterials hydroxyapatite (HAP) and fluorapatite (FAP) on cultured human osteoarthritis type B synoviocytes by analyzing interleukin-1 alpha (IL-1 alpha) production and arachidonic acid metabolism via lipoxygenase pathways. A portion of opsonized particles was endocytosed and was found in numerous phagolysosomes in human synoviocyte cytoplasms. The present study demonstrates that HAP and FAP calcined at 700 degrees C induced a decrease in IL-1 alpha production but markedly decreased the synthesis of lipoxygenase products after 1-month incubation with the particles. This model will allow us to study the possible inflammatory response (arachidonic acid metabolism, proinflammatory cytokines) that can be induced by any biomaterials used in orthopedics.

Abstract
PURPOSE OF THE STUDY We report a case of elastofibroma and have collected 280 cases in the literature. MATERIAL AND METHODS A 56 year-old man presented with a right subscapular mass. The patient was asymptomatic but he reported a "clicking"sensation associated with mobilization of the shoulder. Physical examination revealed a round mass clearly demonstrated with forward elevation of the arm. The MRI scan showed a heterogeneous soft tissue composed of inhomogeneous density with areas of more intense signal suggesting adipose tissue. The tumor was surgically excised and the diagnosis of elastofibroma was established by histopathologic examination. RESULTS Six months after removal of the mass, there were no functional complications. DISCUSSION Elastofibromas usually occur in active patients generally older than 55 years of age. They are typically located in the right subscapular region. The tumor remains asymptomatic in more than 50 percent of cases. 25 percent of the patients may report a simple discomfort sometimes with a "clicking" or "catching" sensation associated with mobilization of the arm. Pain is present in less than 10 percent of cases. Physical examination may reveal a rubbery, asymptomatic mass located in the subscapular region and barely noticable when the arm lies again the chest. Plain radiographs and preoperative laboratory data were unremarkable. CT scan or MRI scan may show an heterogeneous fibrous mass of intermediate density with entrapped signals of higher intensity. However, a definitive diagnosis requires a biopsy showing the distinctive feature of elastofibroma: elastic fibers in a collagenized fibrous tissue with entrapped adipose tissue. Pathogenesis of elastofibromas may result from the friction of the scapula against the thorax thus generating tumor growth. CONCLUSION Complete surgical excision in symptomatic patients is considered to be the treatment of choice. However, once the diagnosis of elastofibroma has been established, excision of lesions smaller than 5 cm can be avoided in asymptomatic patients.

Abstract
As conventional therapy of osteosarcoma is aggressive and its success relatively poor, notably in cases relapse, we investigated the therapeutic effect of retroviral herpes simplex thymidine kinase (HSV1-TK) gene transfer into a human osteosarcoma cell line. Transfected target cells are sensitive to ganciclovir (GCV) (IC50 0.1 microM), and a potent bystander effect, by which cell death can be induced in HSV1-TK negative dividing cells located in the vicinity of HSV1-TK positive ones, is demonstrated. This is significant for clinical applications as no available gene transfer method can achieve 100% transduction to target cells.

Abstract
Previous results have demonstrated the efficiency of Herpes simplex type 1 thymidine kinase (HSV1-TK) retroviral gene transfer and ganciclovir (GCV) treatment of a human osteosarcoma cell line resulting in the death of the cell population and a proximal bystander effect; therefore, we investigated gene therapy on an in vivo osteosarcoma rat model. For in vivo experiments, small fragments of tumor were grafted onto rats in a paratibial position. Seven days after the graft, packaging cells (psi CRIP-TK and psi CRIP-LLZ) were inoculated into tumor mass, followed by GCV administration. In vivo results showed the efficiency of this system that allowed the reduction of the tumor mass and prevented lung metastasis appearance, which represents the normal evolution. This type of treatment seems promising for rapidly proliferating tumors such as osteosarcoma; the lower IC50 makes this system particularly attractive as clinically doses may be of low magnitude to prevent secondary effects in patients.

Abstract
PURPOSE OF THE STUDY A clinical and radiographical study with CT in 30 cases was undertaken in femoral fractures fixed with Russel-Taylor intramedullary nail. MATERIAL AND METHODS In this retrospective study of 57 femoral fractures (mean follow-up 22 months), all fractures were analysed according to the classification of Wiss and Winquist-Hansen-Clawson. Fixation was performed with Russel-Taylor intramedullary mailing. Fifty fractures were classified as unstable due to the type of fracture and for its localization. Analysis of the clinical and radiographical results was performed immediately postoperatively and later by CT (30 cases). RESULTS Clinical results showed seven cases of hip pain and limited walking capability; twenty with decreased hip mobility; twenty-one with functional impairment of the knee with limited flexion (11 cases) and/or knee sprain (15 cases). Radiographical results showed sixteen cases of leg shortening inferior to 1 cm, three between 1 and 2 cm, and one exceeded 2 cm; nine with varus angulation of 5 degrees, one with valgus angulation of 5 degrees, and seven with external rotation exceeding 10 degrees, five with internal rotation exceeding 10 degrees. Results were determined according to Thorensen's criteria. DISCUSSION The use of Russel-Taylor intramedullary nail for the management of complex femoral fractures is discussed. Rotational deformities appeared related to the quality of reduction during surgery. Because of the stiffness of this type of nail, a smaller diameter can be used. Result analysis demonstrates that static nailing should probably be used more frequently in unstable femoral fractures.

Abstract
This work reports the development of a test to evaluate the biologic effects of implant material used in orthopaedics and traumatology based on the examination of inflammation and allergic reactions at the cellular level. The variation in arachidonic acid metabolite production by murine peritoneal macrophage cultures was studied using different powders of implant material. Macrophage activation by zymosan served as a control. Mouse peritoneal macrophages were labeled with 14C-arachidonic acid, and the synthesis of cyclooxygenase products (6-keto-prostaglandin F1 alpha; prostaglandins F2 alpha, E2, D2; and thromboxane B2) and lipoxygenase products (hydroxyeicosatetraenoic acids) was analyzed and quantified by chromatography. Results obtained through these assays support the reported clinical data that chrome and nickel increase the production of hydroxyeicosatetraenoic acids by mouse peritoneal macrophages. HXPATRI, titan oxide, and monoclinic zircon also increase the production of hydroxyeicosatetraenoic acids in contrast to other powders tested (alumina, HXPBL, chrome cobalt alloy, stainless steel 316L, titan, quadratic zircon), which have little effect on the production of arachidonic acid metabolites by the lipoxygenase pathway. It is concluded that determination of arachidonic acid metabolite production by murine peritoneal macrophage cultures is appropriate for evaluating implant material.

Abstract
Fractures on the base of the first metacarpal are uncommon lesions, affecting young subjects and have major social repercussions (an average of 3.5 months off work). The authors have analysed the clinical and radiological results of a series of 138 recent fractures of the base of the first metacarpal with a mean follow-up of 7 years (12 month-14 years). They used a classification into 5 types (Bennett's with a large fragment = 22%, Bennett's with a small fragment = 20%, Rolando = 15%, extraarticular fractures = 36%, Comminuted fractures = 6%) which are easy to recognize on standard x-rays, or preferably on Kapandji views, allowing a standardized therapeutic approach. 70% of patients were younger than 40 and in one half of cases the causal accident was a motor vehicle accident. 12% of fractures were open and 45% were associated with other traumatic lesions. In this series, 35% of cases were treated orthopedically, 57% according to Iselin's technique, 5% by direct osteosynthesis and 3% by external fixation with a mean immobilization of 40 days. A number of clinical and radiological criteria were studied in the 88 patients reviewed. A 100-point grading system was established and, independent of the type of treatment, the authors obtained 61% of very good results, 23% of good results, 12% of moderate results, 2% of poor results and 2% of very poor results. Articular lesions constituted a factor of severity and failure to respect opening of the commissure appeared to be more pejorative than a small imperfection of reduction. The authors noted that simple treatment according to Iselin's technique still has many indications despite progress in miniaturized osteosynthesis.

Abstract
The authors report an open study of 30 cases of intradiscal injection of triamcinolone hexacetonide in the treatment of sciatica. The patients were monitored at months 1 and 3. The results were judged to be good in 36.6% of the cases, moderate in 36.6% and poor in 26.7% of the cases. Two adverse effects were reported: 1 case of reversible urinary retention and 1 case of deficiency of the dorsiflexor muscles of the foot. The good results reported in previous series were only found in this study when the indications were restricted to certain favourable prognostic factors: duration of sciatica less than 6 months and CAT-scan appearance of discal hernia. This technique has the advantage of being simple, economical and nonallergic. On the basis of the encouraging results of the initial series, this technique should be considered as an interesting therapeutic alternative in sciatica. Larger series and double-blind studies, however, are necessary to confirm the initial results.

Abstract
The authors present a biomechanical study of tendon behavior after primary suturing and early active mobilization. In this animal study (23 specimens), three types of sutures are compared using 2 biomechanical parameters: the load at rupture (R), and Young's modulus of elasticity (E). The authors show that early mobilization does not compromise the final strength of a tendon. Moreover, early mobilization confers the biomechanical characteristics of resistance and elasticity more closely akin to those of the normal tendon. Pathoanatomical examinations confirm the fibroelastic reaction of cicatrization and the mechanical role of mobilization in the orientation of newly formed tendon fibers.
