High Rates of Imminent Subsequent Fracture After Femoral Neck Fracture in the Elderly.

BACKGROUND: Fragility fractures of the hip are known to be followed frequently by subsequent fragility fractures, including second hip fractures. Data on subsequent fractures are available for aggregated index femoral neck and intertrochanteric femoral fractures, grouped generically as hip fractures, but not specifically for femoral neck fractures. There is increasing recognition that a subsequent fracture often occurs early after a hip fracture in the elderly, creating an emphasis on the concept of "imminent fracture risk." Since 2000, there have been many reports on the care gap in interventions after a fragility fracture, with concern regarding the slow uptake of appropriate systemic treatments designed to prevent a subsequent fracture in high-risk patients. METHODS: As planned a priori, we performed an analysis of subsequent fractures after an index femoral neck fracture in 2 prospective clinical trials involving 2,520 patients from 90 sites on 5 continents. We recorded the incidence and time of occurrence of all secondary fragility fractures as well as the reported use of bone-protective medication in all subjects. RESULTS: In the 24 months following the index femoral neck fracture, 226 (9.0%) of 2,520 patients sustained at least 1 subsequent fragility fracture, including 113 hip fractures (4.5%). The median interval from the index fracture to a subsequent fracture was approximately 9.0 months. Only 25.2% (634) of the 2,520 patients reported using bone-protective medications at any time during follow-up. Female patients, those with nondisplaced index fractures, and those treated with arthroplasty, were more likely to have received protective medication. CONCLUSIONS: Subsequent fractures, including second hip fractures, occurred frequently and early following an index femoral neck fracture in 2 large global cohorts. Interventions to prevent a subsequent fracture were instituted in only 1 of 4 patients, even though a focused directive was included in both study protocols. LEVEL OF EVIDENCE: Prognostic Level II .

A customized percutaneous three-dimensional-printed guide for scaphoid fixation versus a freehand technique: a comparative study.

The aim of this study was to compare the accuracy and reliability of percutaneous fixation of minimally displaced scaphoid fractures using a customized three-dimensional (3-D)-printed guide with a conventional freehand method. A prospective cohort of ten patients underwent scaphoid fixation with the aid of a customized 3-D-printed guide. The final screw position, total surgery time (minutes) and fluoroscopy time (seconds) was compared with a retrospective cohort of ten patients who underwent fixation with a conventional technique. There were no differences in final screw position between both methods. The patients in which the 3-D guide was used had a surgery time reduction of 43% and a fluoroscopy time reduction of 52% compared with the control freehand group. The use of a customized 3-D-printed guide permits a fixation that is as accurate as the standard freehand technique, with reduction in surgical time and intraoperative radiation exposure.Level of evidence: III.

Timing and Management of Surgical Site Infections in Patients With Open Fracture Wounds: A Fluid Lavage of Open Wounds Cohort Secondary Analysis.

BACKGROUND: Many studies report on the incidence or prevalence of fracture-related surgical site infections (SSIs) after open fractures; however, few studies report on their timing and management outcomes. To address this gap, we used data from the Fluid Lavage of Open Wounds trial to determine timing of diagnosis, management, and resolution of SSIs. METHODS: All participants included in this analysis had an SSI after an open fracture. Participants were assigned to a group based on the type of SSI as follows: (1) those who developed a superficial SSI and (2) those who had either a deep or organ/space SSI. Descriptive statistics characterized the type, timing, and management of each SSI. RESULTS: Of the 2445 participants in the Fluid Lavage of Open Wounds trial, 325 (13.3%) had an SSI. Superficial SSIs were diagnosed significantly earlier [26.5 days, interquartile range (IQR) 12-48] than deep or organ/space SSIs (53 days, IQR 15-119). Of the 325 patients with SSIs, 174 required operative management and 151 were treated nonoperatively. For SSIs managed operatively, median time for infection resolution was 73 days (IQR 28-165), and on average, 1.73 surgeries (95% confidence interval 1.58-1.88) were needed during the 12 months follow-up. There were 24 cases whose SSIs were not resolved at the time of the final follow-up visit (12 months). CONCLUSIONS: Based on this study's findings and in contradistinction to the Centers for Disease Control and Prevention guidelines, after an open fracture, superficial SSIs were diagnosed at one month and deep/organ/space SSIs at 2 months. This information can allow for earlier infection detection. In addition, the knowledge that approximately 50% of the SSIs in our study required a reoperation and 3 months at a minimum to resolve will assist orthopaedic surgeons when counseling their patients.

"Can patients learn how to reduce their shoulder dislocation?" A one-year follow-up of the randomized clinical trial between the Boss-Holzach-Matter self-assisted technique and the Spaso method.

OBJECTIVE: The aim of this study was to assess the effectiveness and reproducibility of self-assisted Boss-Holzach-Matter (BHM) technique compared with the Spaso (Sp) method for shoulder dislocation. METHODS: We conducted a follow-up at 1 year from the randomization of 60 patients with shoulder dislocation enrolled in the study "Teaching patients to reduce a shoulder dislocation." Half of these patients had been taught the self-assisted technique, whereas the other half had been treated by a physician's manipulative maneuver for reduction. We surveyed all the enrolled patients to describe recurrence rates and reproducibility for both the techniques without supervision as well as the number of emergency visits. RESULTS: In total, 52 patients (age range: 18-44 years) answered the survey from the 60 patients enrolled in the study. The total rate of recurrence was 38.5% (20 patients). For the Sp group, 4 of the 30 patients were lost. There were 9 recurrent patients (30%), and 7 were treated in the emergency department (ED). For the BHM group, 4 of the 30 patients were lost. There were 11 recurrent patients (37%), and 2 were treated in the ED. The difference in self-reduction rates and ED visits for both the groups was statistically significant (p=0.025). CONCLUSION: Teaching the BHM technique to the patients is effective and reproducible without direct supervision. It can decrease the number of visits to the ED and is a valid option to teach the patients at risk of recurrence when not being able to get immediate help.

How Successful Is Antibiotic Treatment for Superficial Surgical Site Infections After Open Fracture? A Fluid Lavage of Open Wounds (FLOW) Cohort Secondary Analysis.

BACKGROUND: Although many studies report the incidence and prevalence of surgical site infections (SSIs) after open fractures, there is limited information on the treatment and subsequent outcomes of superficial SSIs in patients with open fractures. Additionally, clinical studies describing the factors that are associated with persistent infection after nonoperative treatment with antibiotics for patients with superficial SSIs are lacking. QUESTIONS/PURPOSES: Therefore, we asked: (1) What proportion of patients with superficial SSIs after open fracture treatment developed persistent infection after nonoperative treatment (that is, treatment with antibiotics alone)? (2) What risk factors are associated with SSIs that do not resolve with nonoperative (antibiotic) treatment? As a secondary objective, we planned to analyze the microbiological information about participants wound cultures, when these were available, and the proportion of positive cultures for patients whose SSIs were not resolved by antibiotics alone. METHODS: This is a secondary analysis of the Fluid Lavage of Open Wounds (FLOW) trial dataset. The FLOW trial included 2445 patients with operatively managed open fractures. FLOW participants who had a nonoperatively managed superficial SSI diagnosed in the 12 months post-fracture were included in this analysis. Superficial SSIs were diagnosed in 168 participants within 12 months of their fracture. Of these, 83% (139) had their superficial SSI treated with antibiotics alone. Participants were grouped into two categories: (1) 97 participants whose treatment with antibiotics alone resolved the superficial SSI and (2) 42 participants whose treatment with antibiotics alone did not resolve the SSI (defined as undergoing surgical management or the SSI being unresolved at latest follow-up [12-months post-fracture for the FLOW trial]). Of the participants whose treatment with antibiotics alone resolved the SSI, 92% (89 of 97) had complete follow-up, 6% (6 of 97) were lost to follow-up before 12 months, 1% (1 of 97) withdrew consent from the study before 12 months, and 1% (1 of 97) experienced mortality before 12 months. Of the participants whose treatment with antibiotics alone did not resolve the SSI, 90% (38 of 42) had complete follow-up, 7% (3 of 42) were lost to follow-up before 12 months, and 2% (1 of 42) withdrew consent from the study before 12 months. A logistic binary regression analysis was conducted to identify factors associated with persistent infection despite superficial SSI antibiotic treatment. Based on biologic rationale and previous evidence, we identified a priori 13 potential factors (corresponding to 14 levels) to be included in the regression model. RESULTS: The antibiotic treatment resolved the superficial SSI in 70% (97 of 139) of patients and did not resolve the SSI in 30% (42 of 139). After controlling for potential confounding variables, such as age, fracture severity, and time from injury to initial surgical irrigation and débridement, superficial SSIs diagnosed later in follow-up were associated with antibiotics not resolving the SSI (odds ratio 1.05 [95% CI 1.004 to 1.009] for every week of follow-up; p = 0.03). Sex, fracture pattern, and wound size were not associated with antibiotics not resolving the SSI. CONCLUSIONS: Our secondary analysis of prospectively collected FLOW data suggests that antibiotics alone can be an appropriate treatment option when treating superficial SSIs after an open fracture wound, especially when promptly diagnosed. Further research with longer follow-up time is needed to better identify the natural history of superficial SSIs and possibly some dormant or subclinical infections to help clinicians in the treatment decision-making process.
