RESUMEN

Stress urinary incontinence is common in adult women. The use of introital or trans-labial ultrasound can help the surgeon (urologist or gynecologist) to better assess the type of incontinence the patient presents in order to guide him in the management of the patient. Often, surgical treatment with a mid-urethral sling (MSU) placement can be chosen in case of failure of non-invasive therapies (such as local estrogen or physical therapy) and if the clinical examination shows an urethral hypermobility. The use of ultrasound can help in this choice. Although rare, complications of MSU can sometimes cause disabling symptoms and be difficult to diagnose. Introital or trans-labial ltrasound can help diagnose them. The objective of this work was to describe the realization of ultrasound of stress urinary incontinence before or after the placement of a MSU, in order to make their realization easier for young surgeons which can use them in current practice.

RESUMEN

OBJECTIVE: To compare the effectiveness and safety of laparoscopic sacropexy (LS) and transvaginal mesh (TVM) at 4 years. DESIGN: Extended follow up of a randomised trial. SETTING: Eleven centres. POPULATION: Women with cystocele stage ≥2 (pelvic organ prolapse quantification [POP-Q], aged 45-75 years without previous prolapse surgery. METHODS: Synthetic non-absorbable mesh placed in the vesicovaginal space and sutured to the promontory (LS) or maintained by arms through pelvic ligaments and/or muscles (TVM). MAIN OUTCOME MEASURES: Functional outcomes (pelvic floor distress inventory [PFDI-20] as primary outcome); anatomical assessment (POP-Q), composite outcome of success; re-interventions for complications. RESULTS: A total of 220 out of 262 randomised patients have been followed at 4 years. PFDI-20 significantly improved in both groups and was better (but below the minimal clinically important difference) after LS (mean difference -7.2 points; 95% CI -14.0 to -0.05; P = 0.029). The improvement in quality of life and the success rate (LS 70%, 61-81% versus TVM 71%, 62-81%; hazard ratio 0.92, 95% CI 0.55-1.54; P = 0.75) were similar. POP-Q measurements did not differ, except for point C (LS -57 mm versus TVM -48 mm, P = 0.0093). The grade III or higher complication rate was lower after LS (2%, 0-4.7%) than after TVM (8.7%, 3.4-13.7%; hazard ratio 4.6, 95% CI 1.007-21.0, P = 0.049)). CONCLUSIONS: Both techniques provided improvement and similar success rates. LS had a better benefit-harm balance with fewer re-interventions due to complications. TVM remains an option when LS is not feasible. TWEETABLE ABSTRACT: At 4 years, Laparoscopic Sacropexy (LS) had a better benefit-harm balance with fewer re-interventions due to complications than Trans-Vaginal Mesh (TVM).

RESUMEN

OBJECTIVE: To assess the incidence of serious complications and reoperations for recurrence after surgery for pelvic organ prolapse (POP) and compare the three most common types of repair. DESIGN: Prospective cohort study using a registry. SETTING: Nineteen French surgical centres. POPULATION: A total of 2309 women participated between 2017 and 2019. METHODS: A multivariate analysis including an inverse probability of treatment weighting approach was used to obtain three comparable groups. MAIN OUTCOME MEASURES: Serious complications and subsequent reoperations for POP recurrence. RESULTS: The median follow-up time was 17.6 months. Surgeries were native tissue vaginal repairs (n = 504), transvaginal mesh placements (n = 692) and laparoscopic sacropexies with mesh (n = 1113). Serious complications occurred among 52 women (2.3%), and reoperation for POP recurrence was required for 32 women (1.4%). At 1 year the cumulative weighted incidence of serious complications was 1.8% for native tissue vaginal repair, 3.9% for transvaginal mesh and 2.2% for sacropexy, and the rates for reoperation for recurrence of POP were 1.5, 0.7 and 1.1%, respectively. Compared with native tissue vaginal repair, the risk of serious complications was higher in the transvaginal mesh group (weighted hazard ratio, wHR 3.84, 95% CI 2.43-6.08) and the sacropexy group (wHR 2.48, 95% CI 1.45-4.23), whereas the risk of reoperation for prolapse recurrence was lower in both the transvaginal mesh (wHR 0.22, 95% CI 0.13-0.39) and sacropexy (wHR 0.29, 95% CI 0.18-0.47) groups. CONCLUSIONS: Our results suggest that native tissue vaginal repairs have the lowest risk of serious complications but the highest risk of reoperation for recurrence. These results are useful for informing women and for shared decision making. TWEETABLE ABSTRACT: Laparoscopic sacropexy had fewer serious complications than transvaginal mesh and fewer reoperations for recurrence than vaginal repair.

RESUMEN

OBJECTIVE: To determine the usefulness of mid-urethral slings (MUS) in the surgical management of women presenting with urinary stress incontinence (USI) METHOD: A consensus committee of multidisciplinary experts (CUROPF) was convened and focused on PICO questions concerning the efficacy and safety of MUS surgery compared to other procedures and concerning which approach (retropubic (RP) vs transobturator (TO)) should be proposed as a first-line MUS surgery for specific subpopulations (obese; intrinsic sphincteric deficiency (ISD); elderly) RESULTS: As compared to other procedures (urethral bulking agents, traditional slings and open colposuspension), the MUS procedure should be proposed as the first-line surgical therapy (strong agreement). MUS surgery can be associated with complications and proper pre-operative informed consent is mandatory (strong agreement). Mini-slings (SIS/SIMS) should only be proposed in clinical trials (strong agreement). Both RP and TO approaches may be proposed for the insertion of MUS (strong agreement). However, if the woman is willing to accept a moderate increase in per-operative risk, the RP approach should be preferred (strong agreement) since it is associated with higher very long-term cure rates and as it is possible to completely remove the sling surgically if a severe complication occurs. The RP approach should be used for the insertion of MUS in a woman presenting with ISD (strong agreement). Either the RP or TO approach should be used for the insertion of MUS in an obese woman presenting with USI (strong agreement). In very obese women (BMI ≥35-40kg/m2), weight loss should be preferred prior to MUS surgery and bariatric surgery should be discussed (strong agreement) CONCLUSION: The current Opinion provides an appropriate strategy for both the selection of patients and the best therapeutic approach in women presenting with USI.

RESUMEN

INTRODUCTION: Inflammatory and sensory chronic bladder diseases have a significant impact on quality of life. These pathologies share alteration of the layer between urine and urothelium, making the use of topical agents appropriate. OBJECTIVES: Review the efficacy and tolerance of intravesical treatments for these pathologies. Give practical guidelines for the use of agents currently available in France. METHOD: A narrative review was performed in March 2021 using PubMed/MEDLINE, Google Scholar and the international guidelines. Pharmaceutical companies and pharmacies were interviewed. RESULTS: Although numerous molecules were tested over the last 5 decades, only dimethylsulfoxyde and glycosaminoglycans are available in France today. Results are promising: response rates are up to 95% and 84% respectively in bladder pain syndrome. In urinary tract infections, glycosaminoglycans could decrease annual number of cystitis by 2.56 (95% confidence interval (CI) -3.86, -1.26; P<0.001) and increase the time to first cystitis recurrence by 130 days (95% CI: 5.84 - 254.26; P=0.04). In radiation cystitis, results could be comparable to hyperbaric oxygen regarding pain and frequency of voiding (-1.31±1.3 visual analogic scale et -1.5±1.4 voiding per day, respectively, at 12 months, P<0.01). However, literature has a low level of evidence. CONCLUSION: Chronic bladder diseases have limited treatment options. Intravesical agents are a good alternative, although their cost is significant and their outcome uncertain.

RESUMEN

INTRODUCTION: Placement of a mid-urethral sling is the gold standard in the surgical management of stress urinary incontinence in women in France. The cure rate of this material is no longer to be demonstrated, but the per- and post-operative complications are currently the subject of a growing controversy not only in Europe but also across the Channel and across the Atlantic, having led to the modification of operative indications. In France, recommendations are also evolving with a stricter framework for indications for surgery by multidisciplinary consultation meeting and an obligation for postoperative follow-up in the short and long term. OBJECTIVES: In this context, CUROPF realized a review of the literature bringing together the available scientific evidence concerning the occurrence of per- and post-operative complications relating to the installation of mid urethral sling. The bibliographic search was carried out using the Medline database and 123 articles were selected. RESULTS: Analysis of the data highlights various complications, depending on the implanted material, the patient and the indication for surgery. The retro-pubic mid urethral sling provides more bladder erosion during surgery (up to 14%), more suprapubic pain (up to 4%) and more acute urinary retention (up to 19,7%) and postoperative dysuria (up to 26%). The trans obturator mid-urethral sling is responsible for more vaginal erosion during the operation (up to 10,9%), more lower limb pain of neurological origin (up to 26,7%). The risk of developing over active bladder is similar in both procedures (up to 33%). But these risks of complications must be balanced by the strong impact of urinary incontinence surgery on the overall quality of life of these women. CONCLUSION: Thus, surgical failure and long term complications exist but should not limit the surgical management of stress urinary incontinence with mid urethral tape. Women should be treated with individualized decision-making process and long-term follow -up is necessary.

RESUMEN

INTRODUCTION: Vaginal LASER therapy is increasingly used in the field of urogynecology, but several points remain unclear. Our goal was to produce a systematic review of available evidence and provide a critical appraisal of available data. METHODS: A systematic review until march 2020 was conducted using PubMed/MEDLINE, Cochrane and Embase databases. All studies about vaginal LASER use in the field of urogynecology were included. RESULTS: Forty studies have been included (8 for genitourinary syndrome of menopause, 19 for stress urinary incontinence, 3 for overactive bladder, 7 for urogenital prolapse, 3 for other indications). Data were heterogeneous, and level of evidence was weak or very weak. Few studies were comparative, and only 3 were randomized). Mild improvement of symptoms and quality of life and limited satisfaction were seen for genitourinary syndrome, stress urinary incontinence, overactive bladder and prolapse. Few adverse events were reported. However, major methodological biases were noted regarding efficacy and safety evaluation. No long-term results were available. CONCLUSIONS: While Vaginal LASER therapy seem to provide encouraging results, the level of evidence supporting its use was weak, especially regarding long-term outcomes. Studies of better quality are warranted before any recommendation can be made. Current use should be limited to clinical research.

RESUMEN

OBJECTIVE: To assess the short-term incidence of serious complications of surgery for urinary incontinence or pelvic organ prolapse. DESIGN: Prospective longitudinal cohort study using a surgical registry. SETTING: Thirteen public hospitals in France. POPULATION: A cohort of 1873 women undergoing surgery between February 2017 and August 2018. METHODS: Preliminary analysis of serious complications after a mean follow-up of 7 months (0-18 months), according to type of surgery. Surgeons reported procedures and complications, which were verified by the hospitals' information systems. MAIN OUTCOME MEASURES: Serious complication requiring discontinuation of the procedure or subsequent surgical intervention, life-threatening complication requiring resuscitation, or death. RESULTS: Fifty-two women (2.8%, 95% CI 2.1-3.6%) experienced a serious complication either during surgery, requiring the discontinuation of the procedure, or during the first months of follow-up, necessitating a subsequent reoperation. One woman also required resuscitation; no women died. Of 811 midurethral slings (MUSs), 11 were removed in part or totally (1.4%, 0.7-2.3%), as were two of 391 transvaginal meshes (0.5%, 0.1-1.6%), and four of 611 laparoscopically placed mesh implants (0.7%, 0.2-1.5%). The incidence of serious complications 6 months after the surgical procedure was estimated to be around 3.5% (2.0-5.0%) after MUS alone, 7.0% (2.8-11.3%) after MUS with prolapse surgery, 1.7% (0.0-3.8%) after vaginal native tissue repair, 2.8% (0.9-4.6%) after transvaginal mesh, and 1.0% (0.1-1.9%) after laparoscopy with mesh. CONCLUSIONS: Early serious complications are relatively rare. Monitoring must be continued and expanded to assess the long-term risk associated with mesh use and to identify its risk factors. TWEETABLE ABSTRACT: Short-term serious complications are rare after surgery for urinary incontinence or pelvic organ prolapse, even with mesh.

RESUMEN

INTRODUCTION: The objective of this study was to evaluate the long-term anatomical and functional efficacy, but also the safety of tension-free vaginal mesh in cystocele repair. METHODS: This retrospective and monocentric study included 90 women who underwent a prolapse repair between June 2006 and November 2008. A light-weight polypropylene vaginal mesh (22g/m2, Novasilk COLOPLAST®) was used without any fixation. Females were followed at 1 month, 1 year, 3 years and 6 years. Only long-term results are presented in this study. The anatomical result was assessed by the POP-Q classification and the functional results by standardized symptoms (PFDI-20), sexuality (PISQ-12) and quality of life (PFIQ-7) questionnaires. RESULTS: 6 years after surgery, the follow-up rate was 74%. Anatomically, the prolapse recurrence rate (Ba≥0) was 17% (n=8). Functionally, the overall patient satisfaction rate was 89%. Quality of life and symptoms scores (4,11±8.45 vs. 17.5±14.4 and 35.8±15.9 vs 94±23.4 respectively) were significantly improved (p<0.001). Concerning the prevalence of the complication, the retraction and exposition rate was 1.7% (n=1) and a re-intervention rate was 6.7% (n=4). The rate of de novo dyspareunia was 1.7% (n=1). CONCLUSION: In this short retrospective series of vaginal mesh interposition for cystocele repair, the prevalence of medium-term patient satisfaction was high.

RESUMEN

INTRODUCTION AND HYPOTHESIS: This aim of this study was to evaluate the feasibility and usefulness of an ovine model for training in vaginal surgery. METHODS: Four senior urogynaecological surgeons and five residents attended five sessions of vaginal surgery for pelvic organ prolapse (POP) in five old multiparous female sheep. Urogynaecological examinations were performed and measurements similar to the POP-Q classification in humans were obtained. Standard POP surgical procedures with and without mesh were performed. A pelvic CT scan was done on one animal and the structures were compared with the pelvic structures in a woman. After the feasibility of vaginal surgery had been established in three cadavers, surgery was performed in two living animals under general anaesthesia and was followed by laparoscopy to explore the internal pelvic anatomy. RESULTS: We found anatomic similarities in the vaginal and pelvic structures between sheep and women. After caudal traction on the cervix, all five sheep had significant POP of stage 3 or 4. We proved the feasibility of all types of vaginal surgery in this animal model: traditional anterior and posterior repair, apex fixation and anterior wall repair with mesh. The video shows the internal pelvic anatomy and different vaginal procedures. CONCLUSION: This study showed that training in vaginal surgery for POP is feasible and useful in an animal model, the ewe, that has vaginal and pelvic structures very similar to those in women.

RESUMEN

Heterotopic pregnancy is an extremely rare condition in which an intrauterine and an extrauterine pregnancy co-exist. In spontaneous conceptions, heterotopic pregnancy occurs in only 1/30 000 pregnancies. The treatment of heterotopic pregnancy must be as minimally invasive as possible to preserve the development of the intrauterine pregnancy. Superfetation, defined as the coexistence of 2 or more foetuses of different gestational ages, remains particularly exceptional and poorly explained (second ovulation? embryonic diapause?). Here, we present an extremely rare case of a spontaneous heterotopic evolutive pregnancy with superfetation, consisting of an embryo in the pouch of Douglas estimated at 8 + 1 weeks of gestation (WG) and a progressive intrauterine pregnancy estimated at 5 + 4 WG. We treated the extrauterine pregnancy with an intra-cardiac injection of potassium chloride echo-guided via the vaginal route, and the patient then underwent exploratory laparoscopy 9 days later and lavage and aspiration of the abdominal heterotopic pregnancy due to pain and biological inflammatory syndrome probably caused by pelvic mass syndrome and peritoneal irritation from the foetal necrosis. She has not yet given birth and is currently at 36 WG.

RESUMEN

Background: In France, 62,000 hysterectomies are performed per year, 70% of which are benign. The choice of approach (laparotomy, laparoscopy or vaginal route) is particularly important in the case of large uterus (> 280g) which are associated with a higher risk of complications. The current data are not sufficient to favour one or other approach. A new medical device, the vNOTES (Natural Vaginal Orifice Transluminal Endoscopy System), offers the advantage of both laparoscopic and vaginal route for pelvic surgery. Objectives: To demonstrate the superiority in terms of intraoperative and postoperative complications of the use of a natural orifice transluminal endoscopic hysterectomy system (vNOTES) versus laparoscopic hysterectomy for benign pathologies on estimated large volume uteri (>280g). Materials and Methods: A randomised, double-blind, superiority trial will be performed at five hospital centres. Women with benign uterine pathology requiring hysterectomy and with a large uterus (> 280g) will be randomised to receive either laparoscopic or vNOTES hysterectomy. Main outcome measures: The primary outcome will be the occurrence of intraoperative and postoperative complications within 6 weeks of surgery. Secondary outcomes will be conversion during surgery, duration of surgery and hospitalisation, postoperative pain, postoperative complications, resumption of sexual life and satisfaction with the surgical team. Results: 248 women will be randomised. Conclusion: This trial will provide a better understanding of the approach to large uteri optimise the care of these thousands of women undergoing hysterectomy. What's new?: This trial will evaluate the vNotes for large uteri.

RESUMEN

Eosinophils are the source of various immunoregulatory cytokines, but the membrane molecules involved in their secretion have not been clearly identified. Here we show that peripheral blood eosinophils from hypereosinophilic patients could express membrane CD86 but not CD80. The T cell costimulatory molecule CD28 is also detected on the eosinophil surface. CD28 ligation but not CD86 ligation resulted in interleukin (IL)-2 and interferon (IFN)-gamma secretion by eosinophils, whereas IL-4, IL-5, and IL-10 were not detected. In contrast to T cells requiring two signals for effective stimulation, CD28 ligation alone was sufficient for optimal eosinophil activation. Eosinophil-derived IL-2 and IFN-gamma were biologically active, as supernatants from anti-CD28-treated cells were able to induce CTLL-2 proliferation and major histocompatibility complex class II expression on the colon carcinoma cell line Colo 205, respectively. Addition of secretory immunoglobulin (Ig)A-anti-IgA complexes, which could induce the release of IL-10, very significantly inhibited both CD28-mediated IL-2 and IFN-gamma release. These results suggest that the release of type 1 (IFN-gamma and IL-2) versus type 2 cytokines by eosinophils is not only differential but also dependent on cross-regulatory signals. They confirm that through activation of costimulatory molecules, eosinophils could function as an immunoregulatory cell involved in the release of both type 1 and type 2 cytokines.

RESUMEN

It has been suggested that neutrophils may be involved in the late-phase reaction of immunoglobulin E (IgE)-dependent hypersensitivity states. However, the identity of neutrophil-associated molecules inducing the release of mediators remains unclear. In this report, we demonstrate that human neutrophils from normal donors or from patients with inflammatory disorders could bind myeloma IgE proteins, especially after desialylation. Northern blot, immunoprecipitation, and flow cytometry analyses revealed that neutrophils did not express Fc epsilon RII/CD23, but rather Mac-2/epsilon binding protein (BP), belonging to the S-type lectin family. Similarly to IgA used as positive control, myeloma IgE proteins, as well as polyclonal IgE antibodies with or without antibody specificity, were both capable of inducing a neutrophil respiratory burst. Anti-Mac-2 but not anti-CD23 mAb strongly decreased the IgE-dependent activation of neutrophils, induced either by the specific antigen or by anti-IgE antibodies. These findings open new perspectives on the functional role of neutrophils in IgE-associated diseases including allergic states or parasitic infections.

RESUMEN

BACKGROUND: Native tissue cystocele repair has been the cornerstone of prolapse surgery, especially since the learned societies warned clinicians and patients about serious mesh-related complications. Surgical techniques mainly consist in anterior colporraphy and vaginal patch plastron. However, success rates of native tissue cystocele repair are heterogeneous, depending on the design of studies and definition of outcomes. To date, high-quality data comparing vaginal native tissue procedures are still lacking. METHODS: Herein we aimed to describe the design of the first randomized controlled trial (TAPP) comparing anterior colporraphy (plication of the muscularis and adventitial layers of the vaginal wall) and vaginal patch plastron (bladder support anchored on the tendinous arch of the pelvic fascia by lateral sutures) techniques. Our aim is to assess the effectiveness of vaginal native tissue repair at 1 year for cystocele with a combined definition of success-anatomic and functional. The primary endpoint will be the success rate 1 year after surgery with a composite of objective and subjective measures (Aa and Ba points < 0 from POP-Q (Pelvic Organ Prolapse Quantification System) and a negative answer to question 3 of Pelvic Floor Distress Inventory and no need for additional treatment). DISCUSSION: A prospective study has found a success rate at 35% for anterior colporraphy based on a combined definition, both anatomic and functional, as recently recommended. However, the definition of anatomic was strict (POP-Q< 2), while it seems that the best definition of anatomic success is "no prolapse among the hymen", that is to say Aa and Ba points from the POP-Q classification < 0. We hypothesize that vaginal patch plastron will have a better anatomic and functional success comparatively to anterior colporraphy because native tissue is added, as it corrects both median and lateral cystoceles thanks to bilateral paravaginal suspension. TRIAL REGISTRATION: CHU LIMOGES is the sponsor of this research (n°87RI18_0013). This research is supported by the French Department of Health (PHRC 2018-A03476-49) and will be conducted with the support of DGOS (PHRC interregional - GIRCI SOHO). The study protocol was approved by the Human Subjects Protection Review Board (Comité de Protection des Personnes) on May 16, 2019. The trial is registered in the ClinicalTrials.gov registry ( NCT03875989 ).

RESUMEN

OBJECTIVES: To evaluate the feasibility and functional urinary and digestive results of nerve sparing techniques in endometriosis surgery. METHODS: A research on the medline/pubmed database using specific keywords (nerve sparing, endometriosis, pelvic nerves) identified 7 publications among about 50 whose purpose was to describe the feasibility, the techniques and the functional results of nerve preservation in this indication. Among them there are: 2 uncontrolled retrospective studies, 3 prospective non-randomized studies, a meta-analysis and a review of the literature. RESULTS: Nerve preservation requires a perfect knowledge of the anatomy of the pelvic autonomic system. The laparoscopic approach is preferred by the different authors due to its anatomical advantage. The feasibility of this technique seems to be demonstrated despite certain limitations in the different studies and depending of the retroperitoneal extension of the lesions. When feasible, it is likely to significantly improve postoperative urinary function (urinary retention) compared to a conventional technique. It is observed no difference regarding digestive function. CONCLUSIONS: Nerve sparing in this indication is a technique the feasibility of which has been demonstrated and is subject to the topography and extent of the disease. In the absence of invasion or entrapment of pelvic autonomic nerves by endometriosis, this technique improves postoperative voiding function (NP3). During pelvic surgery for endometriosis, it is recommended to identify and preserve autonomic pelvic nerves whenever possible (GradeC).

RESUMEN

Polymorphonuclear neutrophils (PMN) are phagocytic cells, able to secrete a large range of cytokines, including inflammatory cytokines, chemokines, as well as the Th1 cytokines interferon-gamma (IFN-gamma) and interleukin (IL)-12. Although PMN do not seem to express IL-10 and IL-13, no information exists on the ability of PMN to produce IL-4. Therefore intracellular flow cytometry was performed in the presence or absence of Brefeldin A. Similarly to eosinophils, freshly isolated neutrophils from normal donors contained low amounts of IL-4, which significantly increased upon culture with Brefeldin A (P < 0001). Immunostaining performed on cytospin preparations of normal granulocytes confirmed the presence of intracellular IL-4. Using a highly sensitive ELISA, the levels of IL-4 secreted by cultured PMN and peripheral blood mononuclear cells (PBMC) were compared. PBMC secrete up to 60 times more IL-4 as PMN but, in the presence of calcium ionophore, only PMN showed a slight but significant increase in IL-4 secretion (P < 0.05). In conclusion, we report here the presence within human PMN of intracellular IL-4, which can at least partly be released under calcium ionophore stimulation. The relevance of this production of IL-4 by human PMN is discussed.

RESUMEN

Trabecular bone microarchitecture and bone mineral density (BMD) are two main factors related to osteoporotic fractures. Currently, however, microarchitecture is not evaluated. We have developed and validated a trabecular bone texture analysis from radiographic images. The objective was to determine if the fractal analysis of texture was able to distinguish osteoporotic fracture groups from control groups, either in vertebrae, hip, or wrist fractures, and to determine if this indicator and BMD were independent and complementary. In this cross-sectional unicenter case-control population study in postmenopausal women, 107 fracture cases were enrolled and age-matched with 197 control cases. This population comprised 40 vertebral fractures (with 70 controls), 30 hip fractures (55 controls), and 37 wrist fractures (62 controls). Hip and lumbar spine BMD were measured by double-energy X-ray absorptiometry. Fractal analysis of texture was performed on calcaneus radiographs and the result was expressed as the H parameter (H = 2-fractal dimension). The H parameter showed a lower value (0.679 +/- 0.053 SD) in fracture cases versus control cases (0.696 +/- 0.030; p = 0.007), the statistical significance persisting after adjustment for age and for lumbar spine (LS) or hip BMD. This result was confirmed in vertebral fractures (p = 0.0001) and hip fractures (p = 0.003) but not wrist fractures (p = 0.07). We determined the threshold between high and low H values and then the odds ratios (OR) of fracture for low H for BMD < or = -2.5 SD in T score and for the combinations of both parameters. The OR of fracture for low H was 1.6 (95% CI, 1.1-2.6). For LS BMD < or = -2.5 SD the OR of 6.1 (3.4-10.8) shifted to 9.0 (4.0-20.4) when we added low H and for hip BMD it shifted from 5.6 (3.3-9.4) to 8.1 (4.0-16.8). In vertebral, hip, and wrist fracture cases the results were also significant. These data have shown that the fractal analysis of texture on calcaneus radiographs can distinguish osteoporotic fracture groups from control groups. This analysis and BMD provide independent and complementary information. These data suggest that we can improve the fracture risk evaluation by adding information related to microarchitecture, derived from analysis of conventional radiographic images.
