Operative treatment of coronoid fracture often requires a large dissection of soft tissue, resulting in elbow stiffness and functional limitation. The authors present a minimal invasive, safe technique, useful in the case of isolated coronoid fracture associated with elbow dislocation. This technique does not require soft tissue dissection and allows an early unlimited resumption of sports activities.

INTRODUCTION: Hip fractures are responsible for excessive mortality, decreasing the 5-year survival rate by about 20%. From an economic perspective, they represent a major source of expense, with direct costs in hospitalization, rehabilitation, and institutionalization. The incidence rate sharply increases after the age of 70, but it can be reduced in women aged 70-80 years by therapeutic interventions. Recent analyses suggest that the most efficient strategy is to implement such interventions in women at the age of 70 years. As several guidelines recommend bone mineral density (BMD) screening of postmenopausal women with clinical risk factors, our objective was to assess the cost-effectiveness of two screening strategies applied to elderly women aged 70 years and older. METHODS: A cost-effectiveness analysis was performed using decision-tree analysis and a Markov model. Two alternative strategies, one measuring BMD of all women, and one measuring BMD only of those having at least one risk factor, were compared with the reference strategy "no screening". Cost-effectiveness ratios were measured as cost per year gained without hip fracture. Most probabilities were based on data observed in EPIDOS, SEMOF and OFELY cohorts. RESULTS: In this model, which is mostly based on observed data, the strategy "screen all" was more cost effective than "screen women at risk." For one woman screened at the age of 70 and followed for 10 years, the incremental (additional) cost-effectiveness ratio of these two strategies compared with the reference was 4,235 euros and 8,290 euros, respectively. CONCLUSION: The results of this model, under the assumptions described in the paper, suggest that in women aged 70-80 years, screening all women with dual-energy X-ray absorptiometry (DXA) would be more effective than no screening or screening only women with at least one risk factor. Cost-effectiveness studies based on decision-analysis trees maybe useful tools for helping decision makers, and further models based on different assumptions should be performed to improve the level of evidence on cost-effectiveness ratios of the usual screening strategies for osteoporosis.

Introduction: Osteoporosis presenting as low-impact fractures to traumatology units is often undiagnosed and under-treated. Results from the Osteocare study in Lausanne (a nurse based intervention, passive pathway) showed that only 19% of patients received management for osteoporosis, and in the literature [1], the rate is between 10-25%. We have evaluated a different management concept, based on the systematic assessment of patients with osteoporotic fractures during and after hospitalization (active pathway). Methods: Inpatients admitted to the Department of Musculoskeletal Medicine for a fragility fracture were identified by a nurse according to a predefined questionnaire and were then clinically evaluated by a doctor. Based on the results, a management plan was proposed to the patients. Patients could choose between follow up either by their GP or by the Centre of Bone Disease of the CHUV. For patients who chose follow-up in our Centre, we assessed their adherence to medical follow-up 1 year inclusion. The results of patients who had been evaluated in our cohort between the 1 November 2008 and the 1 December 2009 were analysed. Results: 573 inpatients received specific management of their osteoporotic fracture over 18 months. The mean age was 77 y (31-99), 81% were women (203 hip fractures, 40 pelvis fractures, 101 arm fractures, 57 vertebral fractures, 63 ankle fractures, and 25 others sites). During the study period, 303 patients received a proposition of a specific treatment. 39 (13%) chose a follow up with the GP, 19 (6%) dead and 245 (81%) preferred a follow up in our Centre. After 1 year, 166 (67%) patients are under follow up in our outpatient clinic. Conclusion: With an active clinical pathway that starts during the hospitalization, consisting on a nursing evaluation followed by a medical consultation by an expert in osteoporosis, the adherence increased from 19% to 67% in terms of follow up. These results lead us to propose a consultation with a doctor experienced in osteoporosis after all osteoporotic fractures.

PURPOSE: Orbital wall fracture may occur during endoscopic sinus surgery, resulting in oculomotor disorders. We report the management of four cases presenting with this surgical complication. METHODS: A non-comparative observational retrospective study was carried out on four patients presenting with diplopia after endoscopic ethmoidal sinus surgery. All patients underwent full ophthalmologic and orthoptic examination as well as orbital imaging. RESULTS: All four patients presented with diplopia secondary to a medial rectus lesion confirmed by orbital imaging. A large horizontal deviation as well as limitation of adduction was present in all cases. Surgical management consisted of conventional recession-resection procedures in three cases and muscle transposition in one patient. A useful field of binocular single vision was restored in two of the four patients. CONCLUSION: Orbital injury may occur during endoscopic sinus surgery and cause diplopia, usually secondary to medial rectus involvement due to the proximity of this muscle to the lamina papyracea of the ethmoid bone. Surgical management is based on orbital imaging, duration of the lesion, evaluation of anterior segment vasculature, results of forced duction testing and intraoperative findings. In most cases, treatment is aimed at the symptoms rather than the cause, and the functional prognosis remains guarded.

Introduction : Les fractures du membre inférieur (MI) de l'enfant traitées par immobilisation plâtrée engendrent une modification significative de la mobilité exacerbée en cas d'obésité. L'accéléromètre est un outil d'évaluation du degré d'activité physique (AP) de l'enfant scientifiquement validé. Il n'a jamais fait l'objet d'étude chez un enfant ayant souffert d'une fracture du MI. Le but de ce travail était d'identifier les problèmes dans l'utilisation d'un accéléromètre comme moyen de mesure de l'AP après fracture nécessitant une décharge du MI. Une adaptation de la réhabilitation post-traumatique en fonction du BMI pourrait alors être proposée. Méthode : Identification d'enfants âgés de 8 et 15 ans, victimes d'une fracture du membre inférieur, consultant aux urgences de l'Hôpital de l'Enfance d'octobre 2013 à mai 2014 et nécessitant une décharge post-traumatique. Etaient exclus les enfants polytraumatisés ou souffrants d'un déficit mental. Données pré-requises des patients: âge, poids, taille, sexe, mécanisme de l'accident, type de fracture et traitement. Proposition de port d'un Actiwatch® Spectrum au poignet et cheville pour la période de remobilisation en décharge. Identification des avantages et problèmes liés à l'usage de l'appareil durant les premiers 30 jours de la période de réhabilitation. Importance : L'absence totale d'étude sur la mobilité post-fracture, la complexité des problèmes liés à la marche en décharge, les contraintes de l'immobilisation plâtrée et la prévalence grandissante de l'obésité pédiatrique justifient la recherche d'un moyen fiable pour quantifier la mobilité d'un enfant en décharge après traumatisme du MI. Résultats : Sur 43 fractures du MI traitées à l'HEL durant la période de l'étude, 13 enfants identifiés, dont 1 exclu pour maladie psychiatrique, 1 refus de participation, 2 transferts immédiats, 2 non inclus pour causes pratiques. Sept garçons âgés de 11 à 16 ans ont accepté le port de l'Actiwatch® pour une durée variant entre 7 et 27 jours (moyenne 15). Nombre d'activités (NA) médians de 5 enfants: 171,79 ±105,37 [cpm]* à J1 et 219,48 ±145,52 [cpm] à J5. NA totales médianes sur 24h : 114'072±44'791 [cpm] à J1 et 234'452 ±134'775 [cpm] à J5. Une dynamique de regain de mobilité est mise en évidence avec intensités maximales et minimales du nombre d'activités pour chacun. La médiane du temps de sommeil des 5 enfants était de 716± 45,5 [mn]. Les problèmes rencontrés ont été d'ordre mécanique (Un Actiwatch® fut défectueux), d'ordre pratique (un perdu et rendu tardivement, un port intermittent, une réaction allergique au bracelet à 4j de port). Conclusions La compliance à l'utilisation de l'Actiwatch® sur toute la durée de la décharge n'était pas optimale. La mobilité moyenne des enfants était objectivable de par leur dynamique, leur intensité maximale et minimale et comparables vis-à-vis de certaines études. Une différence avec les sujets en surpoids est observable. La durée de sommeil de chaque enfant suggère que l'antalgie administrée en cours de traitement est suffisante. Utiliser ce capteur de manière prolongée et sur un grand collectif d'enfants serait un moyen fiable et simple d'objectiver la dynamique de reprise de l'activité physique chez ces patients. Profil de l'étude : observation de cas.

Trabecular bone score (TBS) is a gray-level textural index of bone microarchitecture derived from lumbar spine dual-energy X-ray absorptiometry (DXA) images. TBS is a bone mineral density (BMD)-independent predictor of fracture risk. The objective of this meta-analysis was to determine whether TBS predicted fracture risk independently of FRAX probability and to examine their combined performance by adjusting the FRAX probability for TBS. We utilized individual-level data from 17,809 men and women in 14 prospective population-based cohorts. Baseline evaluation included TBS and the FRAX risk variables, and outcomes during follow-up (mean 6.7 years) comprised major osteoporotic fractures. The association between TBS, FRAX probabilities, and the risk of fracture was examined using an extension of the Poisson regression model in each cohort and for each sex and expressed as the gradient of risk (GR; hazard ratio per 1 SD change in risk variable in direction of increased risk). FRAX probabilities were adjusted for TBS using an adjustment factor derived from an independent cohort (the Manitoba Bone Density Cohort). Overall, the GR of TBS for major osteoporotic fracture was 1.44 (95% confidence interval [CI] 1.35-1.53) when adjusted for age and time since baseline and was similar in men and women (p > 0.10). When additionally adjusted for FRAX 10-year probability of major osteoporotic fracture, TBS remained a significant, independent predictor for fracture (GR = 1.32, 95% CI 1.24-1.41). The adjustment of FRAX probability for TBS resulted in a small increase in the GR (1.76, 95% CI 1.65-1.87 versus 1.70, 95% CI 1.60-1.81). A smaller change in GR for hip fracture was observed (FRAX hip fracture probability GR 2.25 vs. 2.22). TBS is a significant predictor of fracture risk independently of FRAX. The findings support the use of TBS as a potential adjustment for FRAX probability, though the impact of the adjustment remains to be determined in the context of clinical assessment guidelines. © 2015 American Society for Bone and Mineral Research.
